occlusal splint
A removable hard or soft acrylic appliance fitted over the teeth to protect against bruxism, stabilise the temporomandibular joint, or facilitate diagnostic repositioning of the mandible.
Full Definition
An occlusal splint (also called a night guard, bruxism appliance, or stabilisation splint) is a laboratory-fabricated removable device worn over the maxillary or mandibular dentition. It is designed to prevent tooth wear, reduce muscle hyperactivity, and protect restorations in patients who grind or clench. In editorial work, the term appears in laboratory prescriptions, dental journal articles, and patient information documents. Editors should distinguish between a 'stabilisation splint' (flat-plane design for TMD management), a 'repositioning splint' (mandible repositioned anteriorly), and a simple 'night guard' (protective, no therapeutic design).
Usage
Usage note: Use 'occlusal splint' as the preferred clinical term in formal laboratory and journal contexts. 'Night guard' is acceptable in patient-facing copy but should be avoided in technical prescriptions.
