Performance Esthetics - The Vertical Shoulder Laminate Preparation - VSL Veneers Performance Esthetics - The Vertical Shoulder Laminate Preparation - VSL Veneers

Summary:

The Vertical Shoulder Laminate (VSL) Veneer is based upon a unique preparation design that enables accurate reproduction of the facial anatomy of anterior teeth. Traditional veneer preparations focus on conservative tooth reduction, yet little effort is made to ensure that the definitive restoration will have a sufficient structural design to maintain structural integrity under stress. Due to the clinician's desire to perform conservative tooth preparation, anatomic accuracy in the cervical third, incisal third, and interproximal aspects of traditional veneer preparations are neglected. As a result the ceramist is forced to compromise the esthetic and structural quality of the veneer. The VSL veneer preparation design emphasizes tooth morphology rather than conservative reduction. The idea is to provide a stable base on which to build a structurally sound and accurate restoration. Used in conjunction with the VSL veneer preparation the ceramist can recreate tooth contour in the facial, interproximal, cervical, and incisal aspects, which were previously unfeasible with a chamfered margin laminate preparation. If attention is given to to certain anatomic components during the preparation phase, the resultant biomimetic behavior of the porcelain laminate veneer can be optimized.

Consecutive Case Series of Monolithic and Minimally Veneered Zirconia Restorations on Teeth and Implants: Up to 68 Months
The aim of this study was to evaluate the performance of monolithic zirconia in function and minimally veneered zirconia (feldspathic ceramic, not in function, on then facial surface to enhance tooth esthetics or replace gingival structures) on both teeth and implants. The restoration parameters monitored in the patient base were fracture, cracking, or chipping of the zirconia structure and/or the minimally veneered feldspathic ceramic. There were no observed complications with respect to these parameters associated with any of the restorations included in this study.

Interdisciplinary Team Dentistry for Total Dentofacial Esthetics - Part 1 of 2
Orthodontics sets up the foundation for future prosthetics in cases with periodontal, surgical and restorative dentistry requirements. Adult orthodontics simplifies complex clinical situations. Making it easier for restorative dentist to achieve better esthetic & functional results. Orthognatic surgery combined with orthodontics corrects skeletal discrepancies in order to have the patient ready for prosthodontic replacement of multiple missing teeth. Cases combined with implants to restore form & function will further illustrate the importance of multidisciplinary dentistry. Today´s practice requires a team approach that will be presented. In order to meet the patient´s demands for better esthetics and to obtain long term occlusal stability of our results.

“Finally” - Predictable Indirect Conservative Posterior Restorations
Predictable and repeatable results can be achieved through materials and clinical practices that, on one hand, preserve the original structure of the compromised tooth and, on the other hand, involve a very low biologic price. New technologies for the enamel-dentin adhesion and the continuous evolution of more sophisticated esthetic materials (composite resins and porcelains) allow the effective reaching of verifiable and predictable results. This lecture aims to point out the relevant guidelines for obtaining predictable indirect posterior restorations through the evaluation of a correct biomechanical approach rather than giving just a “trendy” adhesive approach.
