Treatment of condylar osteophyte in temporomandibular joint osteoarthritis with muscle balance occlusal splint and long-term follow-up: A case report

Abstract

BACKGROUNDCondylar osteophytes, a remodeling form of temporomandibular joint osteoarthritis (TMJ OA), mainly manifest as marginal angular outgrowths of the condyle. Previous researchers have advocated surgical removal of condylar osteophytes. Reports on the effect of occlusal splint on TMJ OA patients’ joints have mostly focused on treatment with this splint, which can reduce the absorption of the affected condyle and promote repair and regeneration. However, the effect of the splint on the dissolution of condylar osteophytes has not yet been reported.CASE SUMMARYA 68-year-old female patient suffered from occlusal discomfort with left facial pain for 2 years. Cone beam computed tomography showed a rare osteophyte on top of her left condyle. She was finally diagnosed with TMJ OA. The patient refused surgical treatment and received conservative treatment with a muscle balance occlusal splint. The pain experienced by the patient on the left side of her face was relieved, and her chewing ability recovered after treatment. The osteophyte dissolved, and the condylar cortex remained stable during long-term follow-up observations.CONCLUSIONThe muscle balance occlusal splint could be a noninvasive means of treating condylar osteophytes in TMJ OA patients.
