Background: Ankylosing temporomandibular joint (TMJ) is characterized by restricted mandibular movement, pain, and functional limitations. Conservative physiotherapy interventions such as laser therapy and joint mobilization are commonly used; however, evidence regarding their combined effect remains limited.

Objective: To evaluate the impact of Class 3B BEMO Laser therapy combined with joint mobilization techniques in improving pain and range of motion in subjects with ankylosing temporomandibular joint.

Methodology: An experimental study was conducted on 40 subjects diagnosed with ankylosing TMJ. Participants received Class 3B BEMO Laser therapy along with joint mobilization techniques for 6 weeks. Outcome measures included Visual Analogue Scale (VAS), maximum mouth opening (MMO), mandibular protrusion, and lateral excursion. Pre- and post-intervention data were analyzed using paired t-test, one-sample t-test, and repeated measures ANOVA.

Results: Significant improvements were observed in all outcome measures. VAS scores significantly reduced (p < 0.001). Maximum mouth opening improved from 24.63 ± 3.13 mm to 47.70 ± 4.98 mm (p < 0.001). Protrusion and lateral excursions also showed statistically significant enhancement (p < 0.001). Repeated measures ANOVA confirmed a significant main effect of time across variables.

Conclusion: Class 3B BEMO Laser therapy combined with joint mobilization techniques is effective in reducing pain and improving mandibular mobility in subjects with ankylosing TMJ. The intervention demonstrated both statistical and clinical significance
