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

ABSTRACT:

Background

This study aimed to enhance understanding of how unilateral posterior tooth loss (UPTL) affects temporomandibular joint (TMJ) structures and to explore potential influencing factors on joint morphology.

Methods

The study included 68 subjects (34 patients with UPTL and 34 with complete dentition), divided into the missing group (n = 34 joint sides), the contralateral group (n = 34 joint sides), and the control group (n = 68 joint sides). Morphological measurement of the condyle, glenoid fossa and joint spaces were performed using cone-beam computed tomography (CBCT) and Mimics software. Analyses and comparisons were made among the three groups, with subgroup analyses based on the duration of tooth loss (< 1 year and ≥ 1 year), first molar loss, and the presence of
