ZLZhenlong Liu JFJunxi Feng LHLiang Huang

Key Points

This study aims to evaluate clinical and radiographic outcomes of a new posterior occlusal splint in patients with temporomandibular joint osteoarthritis.
Analyzed clinical data from adult patients with TMJ-OA using the novel posterior occlusal splint (nPOS).
Assessed improvements in TMJ-OA symptoms and condylar morphology over 3-12 months.
Retrospective case series design to examine outcomes.
Improvements in key TMJ-OA symptoms were observed during the early to mid-treatment phase.
Positive changes in condylar morphology were noted.
Findings indicate a need for further validation through randomized controlled trials.

Abstract

In this observational study, the use of nPOS was associated with improvements in key TMJ-OA symptoms and condylar morphology, especially during the early to mid-treatment phase (3-12 months). These findings warrant validation in randomized controlled trials before clinical adoption. Furthermore, long-term effects require further investigation.
