“Effect of Remineralizing Agents on Dental Erosion in a Reduced Salivary Flow Population”
This table clinic will provide an overview of remineralization therapies for adult patients with low salivary flow and describe findings of an in situ study comparing the efficacy two remineralization agents.
- To become familiar with contemporary dental literature on agents used for remineralization of adult population.
- To learn the efficacy of two fluoride containing remineralizing agents on erosive surface lesion after one-week application period.
- To compare the remineralization effectiveness of each agent on reduced salivary flow patients (Sjogren’s syndrome) and optimal salivary flow patients.
The prevalence of dental erosion is rising for a variety of reasons in all ages. In addition, the prevalence of patients with hyposalivation has increased steadily over the last decades. Despite good oral hygiene, these individuals present with an extreme risk of developing dental caries and erosion and suffer commonly from progressive dental erosion. Different remineralization strategies have been shown to counteract these deficiencies. However, there is limited evidence to support recommendations. This table clinic will (1) summarize the current evidence on remineralization of a reduced salivary flow population and (2) present research findings of an in situ clinical study comparing remineralization protocols for enamel on patient with low salivary flow. A complete research protocol follows: Objectives: An in-situ crossover design study was carried out to compare the remineralization effectiveness of a high concentration fluoride dentifrice and a remineralizing agent used by a patient, with reduced salivary flow after one week of home application period; specifically Prevident 5000 Toothpaste (1.1 %NaF), MI Paste (CPP ACP), and a positive control 1450 PPM Colgate Cavity Protection. To do so, twenty-one subjects, 11 with reduced salivary flow and 10 with normal salivary flow participated in a double blind crossover design completing 3 arms. In each arm, each participant wore one custom made orthodontic bracket attached to the buccal surface of a mandibular molar containing one slab of demineralized bovine enamel. In one week, subjects completed the treatment regimen brushing twice a day for 1 minute with the test dentifrice, always starting with the 1450 PPM dentifrice. Subjects were randomized to the second two arms to either Prevident or MI paste in combination with 1450PPM fluoride dentifrice. After one week, enamel slabs were retrieved and analyzed using surface microhardness recovery (SMH). Statistically significant difference was observed (p<0.05) in surface microhardness between the pre and post-test for both salivary flow groups amongst all remineralization treatments. No significant differences in SMH recovery were observed between the reduced salivary flow group and normal salivary flow group (p>0.05). In conclusion, a differential effect of remineralizing agents was not discernible between reduced salivary flow and normal salivary flow subjects on early enamel erosion. A 1,450 PPM fluoride dentifrice alone, and in combination with a 5000 PPM prescription strength fluoride dentifrice and a calcium-based product were able to enhance remineralization in both normal and reduced salivary flow patients with a trend towards better remineralization response for the 5000 PPM fluoride dentifrice.

“Orthodontic Treatment in the Interdisciplinary Patient Care”
Attendees will learn about the role orthodontists play in interdisciplinary cases through a case and-evidence based discussion. Specifically: vertical bone augmentation for single teeth; changes in the anterior vertical dimension of occlusion for successful esthetic zone rehabilitation, and; changes in the posterior vertical dimension of occlusion for full mouth reconstruction.
- Learn to recognize cases in which orthodontics can play a vital role in hard and soft tissue augmentation
- Learn about various orthodontic modalities and auxiliaries that may be used when managing inter-disciplinary cases
- Learn about the limitations of orthodontic treatment for interdisciplinary cases.
Orthodontists can play a critical role in interdisciplinary patient care, be it for single-tooth ridge augmentation, or as a prelude to a full mouth rehabilitation. This is especially true when patients have a high esthetic demand. This presentation will focus on the outcomes of several cases with very different needs: extrusion of single teeth to augment the ridge prior to implant placement; correction of a deep overbite with asymmetric gingival display, and; complete change in the vertical dimension of occlusion on a growing patient who will ultimately require a full mouth rehabilitation. The desired versus achieved outcomes of each case will be discussed in the context of the limitations of orthodontic treatment for complex cases. The use of fixedbrackets, removable clear aligners, along with various orthodontic accessories and auxiliaries will be discussed as they relate to each case, as well.

“The Bonded Functional Esthetic Prototype as an Aid in Complex Restorative Cases”
Dentists who take on the complexity of increasing occlusal vertical dimension (OVD), while esthetically redesigning a smile, must address a multitude of issues before confidently moving forward with treatment. This table clinic describes a long -term provisional technique called the bonded functional esthetic prototype (BFEP) that allows dentists and patients to work together to enhance the outcome of therapy.
- Understand how the BFEP can be used as an “occlusal splint” for increasing OVD
- Learn how the BFEP can help during clinical crown lengthening procedures
- Understand how to use the BFEP as a preparation guide.
Dentists who take on the complexity of increasing occlusal vertical dimension (OVD), while esthetically redesigning a smile, must address a multitude of issues before confidently moving forward with treatment. This table clinic describes a long-term provisional technique called the bonded functional esthetic prototype (BFEP) that allows dentists and patients to work together to enhance the outcome of therapy. Increasing OVD is often a necessary, yet complex, step that calls for a conservative approach to treatment planning. Factors to consider include the magnitude of OVD loss, facial esthetics, temporomandibular joint (TMJ) status, remaining tooth structure and occlusion. Given that these factors must be addressed for adequate prognosis, diagnostic wax-ups and articulated mounted study casts are essential tools to provide necessary information for predictable outcomes. One literature review concluded there is limited evidence due to the lack of randomization, appropriate controls, and long-term follow-up to suggest that increasing OVD might cause temporomandibular disorders (TMD). In addition, of those studies that qualified in the reviewers’ parameters, the results do not suggest that a moderate increase of OVD (< 5 mm) correlates with significant TMD symptoms. A separate review supports this and states that a 5-mm alteration is feasible, and that OVD increases greater than this are rarely indicated clinically. Many patients present with mild to moderate anterior attrition that has resulted in a decreased OVD. Traditionally, when increasing OVD, a clinician would provide either a splint or provisional restoration to see how the patient responds to the proposed treatment before a definitive path is taken. However, Poyser et al note that mandibular anterior composites placed at an increased OVD have a success rate of 94% at 2.5 years. In addition, Hemmings et al report similar findings, as they note a success rate of dental composite at 89% over 30 months when placing anterior direct restorations at an increased OVD. The predictable nature of bonding composites to increase vertical dimension in anterior dentition allows clinicians to confidently place long-term temporary composites (< 9 months) to gather information regarding posttreatment symptoms. The BFEP is a provisional technique in which the clinician bonds highly filled, flowable temporary restorations to untouched/minimally prepared enamel/dentin as if they were final restorations.8 A clear matrix is fabricated from the diagnostic wax-up, and the flowable composite is cured through the matrix. With this bonding technique, the patient can function for months to evaluate the phonetics, lip support and OVD, as well as the esthetics of the new smile design. This allows clinicians to evaluate how the definitive prostheses (such as veneers or crowns) will affect a patient’s occlusion, and to identify possible pitfalls that may cause the prostheses to fail.

“Bioactive Restorative Materials in Operative Dentistry: Are We There Yet?”
Bioactive materials have now emerged in product compositions for clinical uses in restorative dentistry. Resin-based materials such as liners, cement, and most recently, fillings materials are claimed to be bioactive. We aim to report the applications, benefits, and update evidence on commercially available bioactive restorative materials and discuss further developments to meet additional restorative clinical needs for the newly emerging category of dental materials.
- Define bioactive restorative materials and explain what it meant by the term “ bioactive”
- Summarize the applications, benefits and update evidence on commercially available bioactive restorative materials
- Describe the updated evidence and ongoing research on new bioactive restorative materials
Bioactive materials have evolved over the past three decades from relatively specialized, highly biocompatible, but low-strength dental materials to now emerge in product compositions for expanded clinical uses in restorative dentistry. With it, the term “bioactive” has become a trend in dental materials marketing, but many clinicians and researchers are struggling to understand what it truly means. Until recently, restorative polymeric fillings present no bioactivity. The complexity of oral biofilms contributes to the difficulty in developing effective novel restorative dental materials. The bioactivity of these platforms aims to the prevention of mineral loss of the hard tooth structure and antibacterial activities against carries-related pathogens. It has been suggested that this bioactivity could minimize the incidence of caries around restorations (CARS) and increase the longevity of such filling materials. The last few years witnessed growing numbers of studies on the preparation evaluations of these novel materials. Herein, we describe several classes of restorative materials that have been termed bioactive and explore the evidence for their claims of bioactivity; also, while it provides product examples for clinical context. We also highlight the status of most studies on calcium phosphate compounds with an eye toward translating the potential of these approaches to the dental clinical reality.

“Remove It or Not? Demineralized Enamel at the Gingival Margins in Class II Preparations”
One of the challenging aspects in class II composite resin restorations would be treatment of the gingival margins of the proximal boxes, especially if demineralized. In this presentation we will discuss how to detect the demineralized gingival margins as well as show how to manage an determine the extension of the margins by a newly developed decision tree at Harvard School of Dental Medicine.
- Detect and diagnose the demineralized gingival enamel margins
- Learn how to determine the extension of gingival margins if demineralized
- Discuss management strategies with the demineralized gingival margins
One of the biggest challenges in class II composite resin restorations is leakage at the gingival margin of the proximal boxes. Several studies have shown increased marginal leakage when the cervical margin is located below the cement-enamel junction (Scotti, 2014, Wibowo 2001, Ozel 2008). It is well-known that adhesion strength and the quality of marginal sealing have different predictability on enamel versus dentin or cementum (Scotti, 2014). Microleakage is not a major concern in restorations when their margins are in enamel, as bonding in enamel is reliable. Clinically, however, margins are frequently placed apical to the cementoenamel junction, on dentin or cementum where moisture control and access for finishing are more problematic. Demineralized enamel is defined as a superficial dissolving of the surface enamel and might be the earliest stage of caries. Demineralized enamel has been often observed at the gingival margins in class II preparations (Antoniazzi 2016). The weaker bond strength on demineralized enamel has been reported, but such enamel may be remineralized with fluoride treatment. There is not yet any article that has compared the bond strength or microleakage of sound enamel, demineralized enamel, dentin and cementum in the same study. In addition, not much evidence-based research has supported the determination of preserving the demineralized enamel or extending the preparation further apically. Thus, it would be essential to establish a protocol on how to determine the extension for proximal box preparations. A suggested decision tree to manage the demineralized gingival enamel margins has been developed and will be shared in this presentation.

“Nanocarriers in Adhesive Dentistry, Small Scale, Huge Potentials!”
One of the common challenges we face as clinicians is secondary caries adjacent to adhesive restorations. This table clinic will present a novel approach to tackle the secondary carious lesions at a nano-level. The use of nanoparticles loaded with therapeutic natural compounds has the potential to improve the longevity of adhesive restorations and might open the doors for a revolutionary concept in oral health care.
- To identify the issues within the current bonding to dentin at the tissue level.
- To list the advantages and the challenges of using Grape Seed Extract as a dentin therapeutic that would consequently prevent secondary carious lesions.
- To describe the rationale beyond using nanoparticles as drug carriers in adhesive dentistry.
Translating basic dental science and biomaterial innovations into our daily clinical applications is imperative for facilitating clinicians’ practice and patients’ care. A major problem with the current dental adhesives is the short durability of the resin-dentin bond that could result in secondary caries and failure of the treatment. Repairing or replacing those materials is inconvenient, costly, time consuming, and it might lead to unnecessary removal of the sound tooth structure. A promising strategy to improve the biostability of collagen at the hybrid layer and improve dentin mechanical properties is biomodification. Such therapy relies on the use of natural compounds, such as proanthocyanidins (PACs), which are naturally derived collagen cross-linkers, most commonly extracted from grape seeds. Grape-seed extract (GSE) has been introduced in the literature with great potential to improve resin-dentin bond stability due to its potential to strengthen collagen and inhibit endogenous proteolysis of the dentin, resulting in the preservation of the bond between the tooth and the resin material. To simplify the use of PACs in the bonding strategy and reduce the number of steps required for their use, PACs should be delivered to the dentin in a simple, sustainable and effective way. The simple addition of PACs to adhesive systems and acid etchants compromises the performance of these materials and results in lower bonding to dentin. Therefore, the use of nano-sized carriers seems to be a promising alternative to overcome current limitations for the clinical translation of dentin biomodification. Nano-sized carriers have been tested and have provided promising results in medicine as a drug vehicle to targeted sites; however, their use in dentistry has been limited. Our group has worked on the synthesis nanocarriers, called Mesoporous Silica Nanoparticles (MSN), loaded with PACs to be incorporated in an experimental adhesive system. MSN will replenish the targeted site (resin-dentin interface) with a continuous long-term supply of GSE which might result in increased longevity of adhesive restorations and no changes in the chemistry, polymerization or mechanical properties of the adhesive material. With collaborative work with other interested researchers we are hoping to be able use this innovative approach in future adhesive systems and in other potential dental applications. We believe that this table clinic would provide an excellent information for the audience in this arena which they might be able to eventually apply it in their clinical practice.

”Creating Optimal Finish Lines in All-Ceramic Preparations”
This table clinic will exhibit the current spectrum of finish margins for ceramic preparations and compare their adherence to the ideal ceramic finish line. Attendees will gain an understanding of the different requirements for feldspathic, lithium disilicate and zirconia ceramic materials.
- Be able to define and identify the difference between a true shoulder, a radial shoulder, a rounded shoulder, an angled shoulder, a true chamfer, a modified chamfer and a heavy chamfer finish line.
- Understand which diamond burs best satisfy the requirements for all-ceramic restorations.
- Know which finish line to use for feldspathic, lithium disilicate and zirconia ceramic materials.
The use of shoulder finish lines to create butt-joint margins has long been the standard to maximize strength, longevity and esthetics of bonded ceramic restorations. Numerous diamond bur shapes have evolved over the past four decades to address these requirements. This presentation will show the resultant finish lines with six different “shoulder” burs on natural tooth structure and compare the shapes generated to desired configurations. Additionally, the spectrum of shoulder finish lines will be compared for ease of scanning for both precision and reproducibility (trueness) using an optical scanner. Finally, the term “heavy chamfer” will be defined and its use and shape will be contrasted for its adherence to, or deviation from, the ideal ceramic finish line for lithium disilicate, feldspathic and zirconia materials.

“A Simple Technique to Fabricate an Immediate Provisional Crown in the Aesthetic Zone”
- Altering soft tissue contours for predictable results with implant restorations
- Providing fixed temporary implant restorations in the aesthetic zone
- Exploring the various material options available for temporary implant restorations
As we all know, bone is the primary determinant of tissue position. Although preservation of bone height and width is the primary focus of all implant restorations, the success of an implant restoration is largely dependent on the final soft tissue position, especially in the aesthetic zone. Therefore, preservation of soft tissue contours after implant placement provides dentists with valuable information and ultimately guides the final restoration design. Fabrication of an aesthetic provisional either at stage I (immediate) or stage II (delayed) may provide the clinician with more predictable final tissue morphology. By making adjustments in the emergence profile a clinician can achieve more desirable final tissue morphology and deal with potential challenges in tissue levels and height prior to final impression. This table clinic presents a simple chairside technique to fabricate provisional implant crowns in the aesthetic zone. This technique can be employed directly in the immediate stage and indirectly in the delayed stage, to provide the patient with an aesthetic, fixed implant provisional crown. In addition, it provides the clinician with an opportunity to control the tissue morphology and emergence profile around an implant restoration so that results with the final implant crown are predictable and as desired.

“CAD/CAM Resin -based Blanks for Long Term Provisional Restorations: An In-Vitro Study”
This table clinic will discuss the various computer-aided design and computer-aided manufacturing (CAD/CAM) resin materials available for the construction of long-term provisional restorations. It will also present a study investigating the load-bearing capacity of resin-based CAD/CAM milled bridges. This would help provide better insight into the various provisional restorative materials available.
- To learn about the various types of resin CAD/CAM blanks currently available for the construction of provisional restorations.
- Describe the advantages of using CAD/CAM technology in the fabrication of long-term provisional restorations.
- Describe the indications for long-term provisional restorations and the possible advantageous material choice to use in challenging restorative cases.
Background: There are several clinical situations where long-term provisional restorative management, up to one year, is needed. The fabrication of strong esthetic restorations in these cases is critical and the choice of material and fabrication technique plays an important role in the success of the restorative treatment plan. A wide range of resin blocks and discs for provisional fixed partial dentures (FPDs) fabrication is available in the market today. Most long-term provisional materials for CAD/CAM are composed of PMMA. Some micro-filled and unfilled PMMA blanks contain built-in shade ranges to better mimic natural teeth shades. Fiberglass-reinforced Epoxy resin blanks are available for milling of high strength biocompatible hypoallergenic long-span FPD frameworks. Acetal resin-based blanks with no free monomer are also available for provisional FPDs fabrication. CAD/CAM technology allows easy use of MMA-monomer free, form- and shade-stable industrially pre-polymerized materials under high temperature and pressure leading to a higher degree of conversion and superior mechanical properties. CAD/CAM resin materials are highly polishable and lightweight. The milled FPD surface shade can be modified with readily available light-cure composite resin mimicking natural dental shades. CAD/CAM long-term provisional resin materials are radiolucent allowing radiological examination of the dental understructure. Data storage of the CAD/CAM fabricated FPDs in the standardized chain of production allows easy reproduction of the restoration and the desired characteristics to be transferred to the definitive restoration. We are presenting an in-vitro study testing the load-bearing capacity of 4-unit long-term provisional FPDs fabricated using CAD/CAM technology from three commercially available resin materials.

“Computer Controlled Dental Local Anesthesia Delivery”
- Convey the importance of patient perception of local anesthesia
- Provide video instruction for the use of the Wand device
- Input benefits to practitioner and patient
All aspects of clinical dentistry with the exception of orthodontia require administration of local anesthesia. As the patient population becomes more discerning, it is incumbent upon clinicians to be proficient in delivering comfortable injections. This presentation will provide information and techniques to allow those who provide local anesthesia to do so in an improved less invasive manner.

“The Evolution of Composite Resin…So Much More than Posterior Fillings”
The composite resin filling should be your “bread and butter”, but did you know it can be so much more?
- To present research that supports routine utilization of composite restorations for posterior teeth
- To demonstrate the endless possibilities of saving teeth with composite resin restorations
- To demonstrate techniques and products that can be used for innovative application of posterior composite resin restorations
Dr. Gammichia has found ways to use composite resin restorations to save teeth from the endless cycle of tooth loss. With the advent of superior adhesion and modern techniques the possibilities are endless. Even severely broken down teeth can be rescued with composite resin restorations (four and five cusps restorations in less than 30 minutes with the most exquisite anatomy.)
We have the ability to make every tooth beautiful while keeping it out of the “cycle of death” for more than a decade. Dr. Gammichia will demonstrate the use of Ribbond to support restorations placed instead of full coverage; he will demonstrate how to avoid full coverage restorations on endodontically treated teeth, and how to restore distal bridge abutments affected by caries and to preserve the bridgework.

"An objective quantitative digital assessment of the resin infiltration/microabrasion of facial anterior white spot lesions"
- State the potential structural/esthetic problem of facial white spot lesions and its clinical management
- Review the current literature/evidence about resin infiltration of anterior facial white spot lesions
- Present a technique using standardized digital photography to measure the effectiveness of resin infiltration/microabrasion of anterior white spot lesions
White spot lesions are defined as enamel surface and subsurface demineralization. If the lesions have not encroached the DEJ, they are usually considered reversible and can be arrested. The process of arresting white spot lesions can take a long time and common problems of arresting these lesions are the darkening of the areas and the potential enamel breakdown because of the lower microhardness of the surface. Microabrasion and infiltration using fluid resin have proven to be valid micro-invasive alternatives compared with traditional conservative therapy to treat these lesion early, before darkening or breakdown of the enamel occurs. This has allowed treatment without any trauma (no use of local anesthesia and cavity preparation) of numerous lesions in only one session with stable clinical (mechanical stability, enamel hardness, conservation of sound tissue) and aesthetic results (disappearance of lesions) over the time. However, the assessment of the esthetic and structural improvement of these techniques has usually been visual without objective tools to quantify the changes after the procedures are completed. This table clinic will present an objective technique to assess the changes in opacity after infiltration/microabrasion of facial anterior white spot lesions using digital standardized clinical photographs. This technique can be applied to any clinical scenario where microabrasion or resin infiltration procedures are executed. The standardization of clinical pictures and their processing/editing/analysis will also be detailed and discussed.

“Injection Molded Direct Composite: Reimagining the Dreaded Black Triangle Treatment”
Closing “black triangles” is arguably the most dreaded direct
restorative procedure of our time. And while legacy methods such as the palatal shelf technique, indirect veneers, or multi-layered posterior composites offer noble solutions, predictability, longevity, and biologic cost are common concerns. Injection overmolded direct composite is a modern-day additive solution that eases these concerns by offering both clinicians and patients an alternative that rivals indirect solutions.
- What is Injection Overmolding?
- How does Injection Overmolding compare to legacy methods such as layering?
- Employing Injection Overmolding as a patient-focused treatment modality for Black Triangles
Injection overmolding is potentially one of the most significant technical advances in the realm of direct restorative since the advent of composite resins. Within the framework of legacy methods, some inherent properties of composites are considered a liability. Polymerization shrinkage is a disadvantage within mechanically retentive cavity preparations and definitive margins. Non-distinct color contrast and handling properties make for difficult interproximal shaping. Depth of cure concerns may lead to early failure if material properties are not fully achieved. With injection overmolding, the fluid nature of composite resin is exploited to optimize the handling and restorative outcomes. Injection overmolding is a three-step process for placement of warmed flowable and regular composite resin. Following air abrasion, total etch conditioning of the tooth, and immediate dentin sealing as needed, adhesive is reapplied then air thinned. Flowable then regular composite is injected into the cavity prep and/or containment before the dual viscosity composites are co-cured. Injection overmolding can be done with any matrix system but most ideally within a clear mylar matrix system. Success of horizontal layering methods are very dependent upon clinician skill. The method lends itself to incorporation of seams and voids which can be a detriment to the final restoration integrity and strength. With indirect restorations, the professional is trending towards monolithic, milled restorations for increased strength. Injection overmolding allows for the creation of monolithic direct composite restorations with improved integrity and more predictable esthetics. One of the most sensible applications of injection overmolding method is the treatment of “black triangles.” Legacy direct composite solutions are prone to ledges and voids, and often necessitate extreme surgical measures such as papillae amputation. Indirect restorations have path of draw concerns which necessitate the removal of tooth structure for restoration strength and seating. The injection overmolding method of warming composite resin improves flow and adaptation around the tooth thus facilitating virtually seamless black triangle closure without the biologic cost of hard or soft tissue removal. As our patient population ages and adult orthodontic treatment gains popularity, public awareness and desire for black triangle solutions will surge. History has shown with digital dentistry and posterior direct composites that patient-demand often guides and helps advance the dental profession. The trend of patients unwilling to sacrifice healthy tooth structure for the elective aesthetic treatment of black triangles is on the rise, thus requiring clinicians to diversify their skillset. Though still in the early stage of adoption, direct composite via injection overmolding offers a viable solution for clinicians seeking an additional treatment modality to meet patient needs.
