Abstract: Objective To analyze the effect of stabilization splint on condylar bone remodeling in patients with temporomandibular disorders (TMD) from the aspect of condylar bone mineral density (BMD) changes. Methods 40 TMD patients treated with stabilization splint were selected. Cone beam computed tomography (CBCT) scanning was taken before and after treatment. The condylar BMD was measured by the Density function of MIMICS 21.0 software, and the condylar BMD of the anterior slope, the top and the posterior slope was analyzed statistically. Results Before and after treatment, the condylar BMD in female was significantly higher than that in male (P<0.05). The condylar BMD in 22–40 age group was significantly higher than that in 13–21 age group (P<0.05). Compared with pre-treatment, the condylar BMD increased significantly after treatment (P<0.05). The condylar BMD of the anterior slope was (347.31±11.98) HU before treatment and (367.69±12.98) HU after treatment; that of the top was (310.46±12.40) HU and (331.20±13.56) HU; the posterior slope was (291.55±13.75) HU and (319.94±14.19) HU respectively. There was no statistical difference of the increment between gender and age. Conclusion There are differences in condylar BMD between gender and age. Stabilization splint is beneficial to TMD patients for a better condylar remodeling.
