A novel combination of treatments for acute anterior disc displacement without reduction of temporomandibular joint

Abstract This study aimed to evaluate the effectiveness of a new combined treatment approach using arthrocentesis, hyaluronic acid (HA) injection, mandibular manipulation (MM), and the Twin-Block appliance (TBA) for managing acute anterior disc displacement without reduction (ADDwoR).

description Abstract This study aimed to evaluate the effectiveness of a new combined treatment approach using arthrocentesis, hyaluronic acid (HA) injection, mandibular manipulation (MM), and the Twin-Block appliance (TBA) for managing acute anterior disc displacement without reduction (ADDwoR). A retrospective cross-sectional study was designed. Thirty-seven patients (38 joints) diagnosed with acute ADDwoR were treated with arthrocentesis plus HA combined with MM and TBA in turn from January 2022 to December 2023. The maximum mouth opening (MMO), visual analogue scale (VAS) pain score, condyle/disc position were measured and comparatively analyzed at baseline and one week, three and six months post-treatment. Analysis of variance, Dunnett’s T3 analysis, and paired samples t-tests were conducted for statistical analyses setting the threshold for statistical significance at P < 0.05. This treatment achieved a success rate of 94.59% (35/37). After one week of treatment, the MMO exhibited a statistically significant improvement, while the VAS pain scores showed a statistically significant decrease (P < 0.001). Magnetic resonance imaging revealed that at six months post-treatment, there was a significant forward shift in the condylar position compared with pre-treatment (P < 0.001),alongside a significant backward movement of the disc on the affected side (P < 0.001).The combination of arthrocentesis plus HA, MM, and TBA can effectively relieve clinical symptoms and restore the disc-condylar relationship in patients with acute ADDwoR.
