An interdisciplinary treatment plan is often required to allow restoration of function and aesthetics in the "mutilated dentition". Loss of teeth is associated with social and psycological impacts for the patient, however most often aesthetic requirements and financial constraints predominate in the treatment decision making. Historically, unfavourable occlusal contacts have been viewed as predisposing factors in the development of temporo-mandibular joint dysfunction (TMD). This linkage has now been refuted by many authors and it is understood that occlusion may be a co-factor only in TMD. In determining the "ideal occlusion" to restore the mutilated dentition consideration must be given to an occlusion that is physiologic for the patient, and the simplest scheme to construct from a clinical and technical view point. In successfully restoring function of the teeth an aesthetic outcome can be achieved. The planning and treatment for three patients is reviewed to highlight interdisciplinary patient care from a prosthodontics perspective.
