Orthodontic Finalization Strategies in Dysfunctional Adult Patients

Abstract:

Although orthodontic treatment for the finalization of temporomandibular dysfunction (TMD) patients is often advocated, it represents a risk of failure. Furthermore, in the literature there are few articles that illustrate appropriate orthodontic strategies for the finalization of these patients. In this article the authors suggest a step-by-step clinical procedure in order to: 1. verify the rationale for orthodontic finalization in TMD patients; 2. illustrate the guidelines for correct orthodontic treatment; and 3. suggest a strategy to stabilize the mandible during orthodontic treatment and to retain that stabilization after treatment. If splint therapy is successful in relieving the TMD symptoms, a fixed posterior bilateral stop is used for occlusal stability. After one or two months during which the bilateral stop is shown to be adequate in maintaining TMJ health without a splint, orthodontic finalization can be performed with minimal risk of failure. The essential sequences of Class I, Class II, and Class III treatment for the finalization of TMD patients are also presented. The difficult goal of a long term stability in cases that have been orthodontically finalized is reached by the conversion of the posterior bilateral stops (crown build-ups) into permanent vertical stops.
