There are a few topics concerning temporomandibular disorders (TMDs) that elicit disagreement and controversy in management of TMJ disorders. The most common one is the use of oral appliances (OAs). There are various types of oral appliances used to relieve TMD symptoms, with several indications, contra-indications, and uses. The uses include diagnostic purpose before any substantial intervention, stabilizing the occlusion to treat TMDs, for proper occlusal positioning, and to prevent occlusal wear or any damage to prosthesis/restorations which are brittle in nature. They are termed based on their uses such as occlusal appliance, mouth/bite guard, orthodontic appliance, surgical splint, or stent. There are several theories based on which the occlusal splints perform its function in various TMD. The presentation will discuss some points of controversy in oral appliances uses.
