NY-9DDS: Webinar: Implant Restorations from Simple to Complex Challenges & Solutions - Part 2

Webinar: Implant Restorations from Simple to Complex Challenges & Solutions - Part 2


Instructor: Leonard B. Kobren, D.M.D.

Part 2 will start with a brief review of the important concepts and protocols described in Part 1 for implant placement based upon the design of the definitive prosthesis. It will emphasize the imperative of utilizing carefully crafted provisional restorations as the template for developing ideal gingival architecture, proper form, function, and esthetics for the definitive prosthesis. While Part 1 concentrated on single-tooth implant supported, multiple-tooth implant supported and combinations of tooth- and implant-supported restorations, Part 2 will concentrate on protocols for full arch and dual arch implant supported restorations. The emphasis will be on proper diagnosis followed by the meticulous sequencing of prosthodontic protocols for establishing and maintaining CR, VDO, and proper occlusal planes from provisional to the definitive restoration. These will enable the practitioner to achieve esthetic success, ideal function, long-term viability and patient satisfaction.
