Abstract

In cases of extensive prosthetic restoration, correction of occlusal contact is often needed, as it is the essential component for a successful restoration. If occlusal contact is given incorrectly, various symptoms of occlusal trauma can occur of which temporomandibular joint disorder (TMD) is one of them. As one of the common symptoms of TMD, patients may suffer with masticatory muscle disorder and temporomandibular joint pain. This case presents satisfactory results for the improvement of masticatory muscles and temporomandibular joint pain of a TMD patient, caused by incorrect occlusal contact of the restoration, by replacing the prosthesis after occlusion correction.

Fig. 3.

T-Scan examination at MIP before treatment. (A) Severe imbalance of occlusal force of right side was observed and the center of force (COF) was biased to the right, (B) About 75% of total occlusal force was biased to the right side (red line), whereas the left side (green line) accounted for about 25% of total occlusal force.

Fig. 5.

Provisional restoration. (A) Frontal view, (B) Maxillary occlusal view, (C) Left lateral view. After removing the previous prosthesis, a temporary crown was fabricated for a uniform occlusal contact at the left premolars and molars. After 5 months of follow-up, pain reduction of the masticatory muscles and TMJ was observed.

Fig. 6.

T-Scan examination at MIP after provisional restoration. (A) Occlusal contact was evenly distributed, and the COF was formed close to the center of the arch. (B) The graph showed 50:50 force distribution in left (green line) and right side (red line).

Final restoration. (A) Frontal view, (B) Maxillary occlusal view, (C) Right lateral view, (D) Left lateral view. Excluding deflective occlusal contact, after installing the new prosthesis with an evenly distributed occlusal contact, pain on the masticatory muscles and TMJ was gone.

Fig. 9.

T-Scan examination at MIP after setting a new prosthesis (A) occlusal contact was evenly distributed and the COF was formed close to the center of the arch. (B) The ratio of left and right forces was balanced. Green and red line overlapped each other at center of graph.
