True
False
Functional indications for transitional prostheses include:
Select all correct answers
preserving the prosthodontic space by preventing unwanted movement of adjacent teeth
assisting phonetics and articulation
enabling mastication to maintain dietary and nutritional status
All transitional prostheses must have a design that allows:
Select all correct answers
surgical access at the planned site
access for effective daily plaque removal by the patient
reshaping as needed for hard tissue management of the implant site
