All prosthetic rehabilitations require healthy, stable oral conditions. The biologic response to the preliminary treatment provides important criteria for planning the final reconstruction and permits testing of the desired prosthetic treatment goals within the unique patient-specific biologic conditions before final restoration. This study used long-term provisional restorations that corresponded in both form and function to the anticipated restorations. Intraoral testing of the diagnostic waxup is an outstanding basis for discussing the provisional as well as final restoration. As required, changes necessary to teeth form and position can be simply accomplished.
