Characteristics of Temporomandibular Joint Osteoarthritis Patients With Condylar Erosion: A Retrospective Cross-Sectional Study.

Background: Condylar erosion (CE) may indicate an active progressive stage of temporomandibular joint osteoarthritis (TMJOA), but no studies have analysed the characteristics of this population.

Objective: This cross-sectional study analysed the characteristics of TMJOA patients with CE.

Methods: A total of 267 patients were included.

Effect of TMJ disc position on condylar bone remodeling after arthroscopic disc repositioning surgery.

Purpose: The objective of this study was to analyze the effect of TMJ disc position on condylar bone remodeling after arthroscopic disc repositioning surgery.

Methods: Nine patients with anterior disc displacement without reduction (ADDWoR, 15 sides) who underwent arthroscopic disc repositioning surgery were included. Three-dimensional (3D) reconstruction of the articular disc and the condyle in the closed-mouth position was performed using cone-beam computed tomography (CBCT) and magnetic resonance imaging (MRI) data.
