By focusing on prosthetic-based rather than bone-based treatment planning, this presentation will show how to avoid the common problems of short clinical crowns, poor emergence profile, inadequate inter-implant/tooth distance, visible prosthesis/tissue transition, and lack of prosthesis strength.
This unique dual lecture presents an easy-to-use recipe based on concepts in common use to control for implant depth angulation and position for the single immediate restoration to the full-arch prosthesis. Having a concept-based formula allows both experienced practitioners and those early in their careers more control, predictability, and confidence to do more with improved results by removing the guesswork from treatment planning. By using an eight-step protocol, the presenters will outline formulae for the placement of an implant body established on evidence-based concepts. For example, it is prudent to assess both the vertical dimension of occlusion and the plane of occlusion prior to using these formulae for placing the implant. The formulae use simple geometric markers based on a prosthetic mockup of the restoration. The presenters will demonstrate how to use the gingival zenith to plan the ideal single immediate implant angulation and depth. A “zenith reference” line will be used to conceptually allow both the surgical and restorative clinician to idealize implant placement. The power of the formulae will allow you to evaluate the prosthetic space in order to idealize both the restorative space and the implant space within in it. We will discuss simple concepts that can be utilized in clinical practice to plan both the analogue or digital implant position. This can be incorporated into a printed surgical template or even utilized in a freehand approach. For the full-arch prosthesis, occlusal reference lines are utilized to plan the desired prosthetic space based on the eight-step protocol. For example, the protocol will be used to demonstrate when it may be appropriate to do either a fixed zirconia bridge or a hybrid prosthesis. The eight-step protocol will allow you to plan the restoration first and in order to visualize any bone reduction, a-p spread, or bar thickness requirements, etc. In summary, this program will provide a checklist approach to idealize implant position for easy restoration. Understanding the eight-step protocol and applying these simple formulae will enlighten the audience to look at all future cases in a new way!
