Use of Mini-anchors and Rehabilitation with 0° Cusp Angle Teeth Complete Denture in Recurrent Condylar Dislocation:...

To report a case of association between the surgical treatment of temporomandibular dysfunction and rehabilitation with denture total prosthesis (TP) using nonanatomic teeth (cusp 0°) in patients with anterior recurrent dislocation of the temporo-mandibular joint (TMJ) and persistent uncontrolled mandibular movement, showing a technical adaptation and conduct.

There are several treatment approaches available for dislocation of the TMJ. The use of condylar mini-anchors for recurrent TMJ dislocation is a valid option and should be considered since it does not alter the joint anatomy. In edentulous patients undergoing TMJ surgical procedures, prosthetic rehabilitation can be seen as a means of treatment preservation.

A 73-year-old female patient attended the oral and maxillofacial surgery clinic presenting with joint instability, ligament laxity, and chronic recurrent TMJ dislocations. She had already been through three previous unsuccessful surgical procedures. A treatment plan was done based on the installation of a mini-anchor in the patient's TMJ through the preauricular surgical access. Dislocations were then resolved, but the lack of mandibular control even to a lesser extent after surgery precluded the use of prosthetics even at rest. Thus, it was planned to manufacture two conventional TPs with 0° cusp angle teeth, a clinical protocol shortened to three sessions in an attempt to improve the stability of the prosthesis.

The use of an individual mini-anchor is simple and effective, and the use of artificial teeth is well suited to the case.

A multidisciplinary intervention (surgery/ prosthesis) is of utmost importance for the resolution and preservation of the treatment of these complex cases.
