Use of occlusal digital splint for treating the patients with temporomandibular joint dysfunction and planning orthopedic treatment

Abstract

Objective of the study: to develop and assess the occlusal digital splint for treating patients with temporomandibular joint dysfunction (TMJD). Material and Methods — 17 patients between the ages of 30 and 49 diagnosed with TMJD were admitted for treatment. To normalize mandibular position, an occlusal digital splint for all patients was manufactured in accordance with our original method. An intensity of pain sensations in all patients prior to, and after, the treatment was assessed by a visual analogue scale, along with the changes in the mandibular movements’ amplitude, and the signs of splint wear and stability of occlusal contacts. Results — Patients have adapted themselves well to the splint and found it convenient in use. The study results showed that it was sufficiently effective in treatment of TMJD. Reduction in pain intensity and restoration of mandibular movements’ amplitude were detected with certainty. Only in 2 (11.7%) cases, the signs of wear on the splint were found, as evidenced by the changes in pre-treatment occlusal contacts. In all other cases throughout the study, a stable occlusal contact has been encountered. Conclusion — Our results indicated that proposed occlusal digital splint may be considered as a treatment option for the patients with TMJ disorders.
