Composite Restoration Using a Two-step Matrix Technique for Gingivally Extensive Lesions

To Bond or not to Bond? The answer to this question is always a puzzle. When the lesion to be restored is subgingival, the answer is blurred furthermore. The two step matrix technique for the restoration of gingivally extensive lesions with glass ionomer first and then with composite is the missing piece to this puzzle. Although technique sensitive, this restoration protocol is effective and predictable. First, clear the tooth of caries and remove all infected dentin from the DEJ and CEJ. After the bonding protocol, the first matrix (modified toffelmire) is placed subgingivally close to the root surface to allow placement of a glass ionomer restoration upto the CEJ. The second matrix (V-ring with sectional matrix) is then used to restore the remainder like a standard class II composite restoration. Occlusion is adjusted and the restoration is then finished and polished. Composite restorations are simple in concept but challenging in reality in most scenarios. It becomes especially technique sensitive when the lesion is deep and subgingival. Using the two-step matrix placement protocol for restoration of a gingivally extensive lesion makes it manageable and predictable towards success and longetivity of the restoration.

Learning Objectives:

  • Understand the importance of establishing a clean periphery when performing direct restorations.
  • Know a method for isolating the extensive gingival wall in a class II preparation for composite.
  • How to build a class II back to ideal controls and contact utilizing a two-step matrix technique.

Efficacy of Direct Restorative Materials in Proximal Box Elevation (PBE) on the Marginal Quality and Fracture Resistance of Molars Restored with CAD/CAM Onlays

Proximal box elevation (PBE) is a conservative technique use to restore severely damaged teeth. However, only a handful of studies have been published regarding the technique’s efficacy. Published studies have evaluated resin-based composites (RBC) and other direct materials to elevate tooth margins. No study to date has compared restorative glass ionomers (GI) and resin-modified glass ionomers (RMGI) to RBCs in elevating tooth margins prior to delivering CAD-CAM (Computer Aided Design-Computer Aided Manufacturing) onlays. The purpose of this study was to investigate the effect of four direct restorative materials (Fuji IX Plus, Fuji II LC, Filtek Supreme Plus, Filtek Bulk Fill uno) that may be used with the PBE technique. Following margin elevation, samples were submerged in water at constant 37 C and subjected to cyclic fatigue (100,000 cycles at 65 N). Margin quality was evaluated with scanning electron microscopy (SEM) at 200x using epoxy resin replicas before and after cyclic fatigue. In addition to margin quality, the fracture resistance of each group was measured using a Zwick 10k testing instrument.

Learning Objectives:

  • How PBE material affects maximum fracture resistance of molar teeth restored with CAD-CAM onlays.
  • How PBE material affects marginal quality of molar teeth restored with CAD-CAM onlays.
  • Ideal material choices for PBE dependent on environment and situation.

Practical Application of 3D Printing in Dental Offices

Over the last decade there has been many advancements in 3D printing technology which included a decrease in costs and increase in accuracy. It is foreseeable that 3D printing will play a huge role in the dental profession. The purpose of this study is to explore new ways in which 3D printing can be applied in the dental field. They included the formation of custom RPD guide plane jigs, jigs which can allow a practitioner to place orthodontic brackets at a precise location, jigs for restorative purposes (ie: diastema closure, cuspal fracture) which will allow the clinician to apply composite against the jig and restore tooth esthetics and function, and the 3D printing of basic dental components such as rubber dam clamps. The completion of the backbone design for a successful rubber dam clamp will help accomplish a few goals. One, it allows for the creation of dental supplies which can be printed in a dental office with ease. Second, the design can be modified and customized for specific clinical purposes Third, it probes into the thought of possibly 3D printing other day to day dental supplies as a convenience and cost saving measure. Overall, as 3D printing becomes mainstream in the dental environment it is important to figure out ways in which it can benefit the delivery of patient care and effectiveness of clinical time.


Learning Objectives:

  • Successfully capture a 3D image of a rubber dam clamp.
  • Develop CAD knowledge and modify rubber dam clamp so that it is compatible with 3D resin.
  • 3D print rubber dam clamp and use intraorally.

Bioactive Materials: Ion Release, Flexural Strength and Secondary Caries Depth

Caries remains a significant clinical problem especially in salivary deficient individuals. Caries development is a dynamic process between demineralization and remineralization of dental hard tissues that eventually results in cavitation. Fluoride releasing materials like resin modified glass ionomers (RMGI) may protect the restored tooth from demineralization, but salivary deficient individuals have limited remineralization since little calcium, phosphate, fluoride or bicarbonate are available. Bioactive materials have begun to appear in the literature and hence the need to understand them better. A bioactive material is one that forms a surface layer of an apatite-like material in the presence of an inorganic phosphate solution. Bioactive materials release calcium, phosphate, and fluoride which may increase tooth remineralization. Limited remineralization data is available demonstrating the superiority of bioactive or ion releasing materials compared to fluoride or no ion releasing materials. Activa, Cention N ,Fuji LC II and Filtek Supreme Ultra were studied. Firstly, the fluoride, calcium and phosphate release of these materials was measured using ion specific electrode at 24 hours, 1 week, 1 and 3, month intervals in deionized water and acidic solution Secondly, the flexural strength of the materials was measured using at 24 hours, 1 week, 1 and 3-month intervals. Thirdly, the efficacy of these materials to prevent demineralization in an artificial caries solution was. measured and compared. In many cases, fluoride releasing materials have inferior mechanical and lower wear resistance compared to non-ion releasing materials. The obtained measurements from all specimen groups should reflect the bioactive nature of calcium and fluoride releasing materials. This study aims to enhance the understanding of the mechanism behind the bioactivity of these materials and emphasise their clinical application.

Learning Objectives:

  • Clinicians will learn a better definition and uses of bioactive restorative materials.
  • The ability of bioactive materials to clinically perform with or without adhesive will be demonstrated.
  • Ion release of bioactive materials will be demonstrated as well as success of these materials in artificial caries solution.
  • Clinical success of one of the bioactive material will be demonstrated.
