title: Revisiting tooth preservation in prosthodontic therapy.
abstract: Dental implants have been established as long-term supports for tooth replacements, and they have profoundly altered treatment concepts of traditional prosthodontics. The use of teeth as prosthetic abutments is revisited relative to implants as predictable support mechanisms for fixed and removable prostheses. The purpose of this review is to appraise tooth preservation in a different manner while considering implants as additional and even preferred support mechanisms for dental prostheses. Data reviewed in this article include a comparison of implants and traditional prostheses and their effects on abutment teeth, the use of periodontally and endodontically compromised teeth as abutments, and prosthetic complications potentially created by healthy remaining teeth. The evidence presented suggests that the longstanding objective of tooth preservation during prosthetic treatment be appended to include the use of dental implants for fixed/removable prostheses, and to avoid or remove teeth presenting as liabilities that diminish the overall prognosis. Patients are not well served if they are faced with biologic, economic, and psychological burdens associated with ongoing revisions of dental rehabilitations using natural teeth. Dentists must use all means available to carefully evaluate remaining teeth to determine if they benefit or impair proposed prosthetic outcomes.
