The report describes a 27‐year‐old female patient with amelogenesis imperfecta (AI) accompanied by nocturnal bruxism, who was treated with a combination of occlusal splint and full‐mouth fixed prosthetic rehabilitation through follow‐ups within 2 years. Soft splint protection, regular follow‐up, and monitoring of carries are guaranteed to maintain a long‐term curative effect.
Background: Occlusal splint therapy, which is a conservative approach to treat temporomandibular disorders (TMDs) and bruxism, can change the occlusal contact of dentition. However, little is known about the variation in bite force and temporomandibular joint (TMJ) sounds. The objective of this case report is to compare the effects of different splint thicknesses constructed by vacuum lamination technology on occlusal function and TMJ sounds. Clinical Presentation: This study presents a 24-year-old male with bruxism. Four splints of different thicknesses (0.6 mm, 1 mm, 2.5 mm and 3 mm) were fabricated and tested. Then, an array of occlusal data were recorded and analyzed by the T-Scan ® III system and joint vibration analysis (JVA). Conclusion: The results reveal that splints of different thicknesses manufactured by the vacuum hot-lamination apparatus may cause a change in occlusal force.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
