"TERMINAL DENTITION...Where doe we draw the line???"
Ricardo Mitrani, DDS,. MSD
For over a decade, the term “Terminal Dentition”, has unquestionably gained a lot of traction in the dental community, and it implies that there is a need to remove a patient’s remaining dentition. But how do we reach such stage or conclusion? Does it mean the same to everybody?
The reality is that the term Terminal Dentition is actually a “dentist made term”.
Of the same token, until this day, there seems to be confusion among dental practitioners as to what is the ideal prosthetic solution for these patients.
This presentation will discuss a linear thought process that allows the treating team to decide when to choose to give up hope on the remaining dentition and how to decide among the different restorative designs available.
- Review a simple Classification (LTR Classification) that helps identify the patient´s condition and therefore decide the ideal treatment design for each given patient.
- Review the different implant assisted/supported prosthetic solutions.
- Improve communication amongst the treating team.
- Review a treatment planning algorithm that allows the treating team to follow a linear thought process in assessing the remaining dentition.

"The evidence behind Minimal Intervention in Cariology- The role of SDF and other non-restorative strategies for caries management"
Margarita Fontana, DDS, PhD
The objective of this presentation is to provide an overview of currently accepted, evidence-based and/or expert opinion recommendations for the management of dental caries lesions, with a focus on non restorative management strategies for caries lesion arrest. Discussions will be centered on current concepts for caries lesion detection (e.g., cavitated and non-cavitated lesions) and diagnosis (e.g., active vs. arrested lesions), including thresholds for non-surgical and surgical interventions, caries tissue removal (selective caries removal, no caries removal, etc.), with a focus on non-restorative strategies for caries lesion control (e.g., fluorides-including SDF, sealants, infiltration, etc.).
At the end of this presentation attendees will be able to discuss:
- Evidence to support use of SDF in non restorative caries management in permanent teeth
- Evidence behind strategies for selective caries removal or no caries removal
- Evidence behind sealing of caries lesions of varying severity

"Ceramic Onlays…Contemporary Guidelines for Clinical Success"
Taiseer Sulaiman, DDS, PhD
Modern operative dentistry has experienced a dramatic rise in awareness of minimally invasive restorations. Clinicians routinely challenge traditional guidelines that instruct on the indications for preparation/restoration design with the goal of conserving as much tooth structure as possible. Further, the development of reliable enamel and dentin adhesive techniques and ceramic materials with improved physical properties has led to a significant increase in the utilization of ceramic restorations in the previous decade. Research focusing on cuspal coverage indications using modern restorative materials is sparse. The few published research studies that evaluated the effect of remaining cusp thickness on fracture rates did not use lithium disilicate ceramic onlays. Additionally, these research studies did not compare possible differences in preparation design of the functional versus nonfunctional cusps. Therefore, the overall objective of this presentation is to develop contemporary clinical guidelines for cuspal coverage indications.
- Classify the different types of ceramic-based materials available partial coverage restorations.
- Compare the mechanical properties of each ceramic type to the natural tooth structure.
- Describe the fatiguing effect may have on different partial coverage designs.
- Describe successful bonding protocols of different partial coverage restorative materials.

The 2019 Richard V. Tucker Lecture of Excellence
"From Casting Gold to Ceramic: Understanding Science Matters"
Chandur Wadhwani, BDS, MSD
Dr. Richard Tucker taught us to simplify but be precise and predictable- this follows through on all aspects of dentistry, including dental Implants.
Gold casting onto UCLA milled abutments for implants has been shown to be damaging to the fit of components due to air particle devesting. To overcome the issue special techniques have been developed. These will be explained along with explanations on the latest studies relating to implant screw loosening- which is still considered the greatest complication in implant dentistry. Simply understanding the dynamics of screw tightening and knowing if the torque limiting device you are using is accurate and precise will also be discussed.
Other issues with dental implants and disease will be explored, all clinically relevant, with much of the research coming from university graduate programs such as Loma Linda, Oregon health Sciences, University of Washington.
You will learn up to date techniques to improve laboratory work. How to check if your torque wrench is calibrated. Implant screw loosening- techniques that reduce incidence. How to monitor the health of dental implants- what you must know.
- Improving gold castings for cast too Implant components: How modifying casting techniques can improve the fit of componentry and increase success rates.
- Screw seating and restorations used in Implant dentistry- what matters. Understanding how screws work to achieve optimum clamping forces with implant componentry- and how to optimize tightening values.
- Ceramics and the push for metal free dentistry- the truth is out there. There is a huge misunderstanding about how metals interact with the human body. What dentists need to understand when discussing treatment options and materials with patients.

"Restoring Endodontially Treated Teeth with the Biomimetic Approach: Stategies, Concepts and Techniques"
Matt Mejad, DDS
The biomimetic approach aims to restore teeth with restorations that mimic natural teeth in strength, function, esthetics, and biomechanical properties. The natural tooth is an absolute testament to the power of adhesion between two drastically different materials (enamel and dentin) which work together harmoniously to withstand the harsh conditions of the oral environment. Frequently, endodontically treated teeth present with substantial loss of natural tooth substrates (enamel and dentin) and we are challenged with restoring this complex structural deficit.
This lecture will cover the concepts behind restoring anything from the most simple and intact endodontically treated teeth to the severely damaged, no ferrule scenarios. An emphasis is placed on prioritizing and utilizing the best restorative strategies possible for a given scenario, but also in restoring teeth which have traditionally been abandoned in-favor of implant-supported restorations. Many patients and clinicians have preferences toward preserving the original root and periodontal ligament in order to postpone more invasive surgical procedures. This lecture will cover the ideal materials and technique to favorably restore teeth presenting with these more complex scenarios.
- Factors affecting successful adhesion (c-factor, polymerization shrinkage and stress, hierarchy of bondability)
- Adhesive build-up strategies for endodontically treated teeth
- Ideal materials and techniques to restore endodontically treated teeth without ferrule

"Fundamentals of Fixed Prosthodontics; Legacy vs Modern Concepts"
Lane Ochi, DDS, FACD, FICD
There is no other field in dentistry where measurable improvement in results can be directly attributed to attention to detail and execution. Just as important as technical improvement is developing an awareness of the interactions of all the choices we make, from preparation design, margin configuration, as well as our luting agent selection. Equally essential is our relationship with our laboratory support. Unfortunately there is not much contact between dentists and laboratory technicians because of the increased size of dental laboratories, technical developments, and our preoccupation with restorative techniques instead of laboratory procedures. We cannot improve our outcomes if errors are made buy us or in the laboratory, making group cooperation and communication mandatory. This presentation will take an honest and critical look at the issues that face both the dentist and our labs.
At the end of the day, we cannot afford clinically unacceptable outcomes in our treatment. Costs lost to time, remakes, and loss of patient confidence are not something we strive for. By understanding the interdependence of the process, you will be able to identify the cause of failures so you can prevent them occurring.
- Understand the interaction between preparation design and luting agent selection to maximize retention
- Be able to evaluate un-retentive preparations and understand how to make structural modifications with the addition of the appropriately located resistance features to improve the retention.
- Understand things dentists do that make lab technicians jobs more challenging.
