A retrospective study of remodeling changes of the temporomandibular joint structures in patients with unilateral posterior tooth loss

An overall enlargement of both the glenoid fossa and joint spaces was observed in patients following UPTL; the glenoid fossa was found to be more susceptible to bone resorption than the condyle. Factors such as the duration of tooth loss, the absence of the first molar, and UCH contribute variably to these structural changes, indicating that different tooth-loss conditions can impose distinct biomechanical impacts on the TMJ.
