A bruxism splint is a special device made of transparent, hard acrylic material, typically placed on the chewing surfaces of all upper teeth. It is mainly used during the night but can also be worn during the day if needed. The purpose of the splint is to prevent the normal application of teeth and balance their pressures, thereby helping to relax the muscles and relieve symptoms related to the temporomandibular system and articulation.

Using the splint provides protection against friction, reduces tooth mobility, and protects potential dental work from wear. It’s important for the splint to be non-porous, made of hard acrylic, allowing free horizontal and lateral movements of the lower jaw. Conversely, soft splints are avoided as they can worsen bruxism.

The treatment process involves taking digital impressions and fabricating the splint by the dental technician. During the final application, occlusion is adjusted, and follow-up appointments are conducted for possible re-adjustment of occlusion over months.
