Occlusal splints are a key component in modern orthodontic practice by safeguarding occlusion and mandibular function during treatment. These personalized oral appliances are fabricated using rigid or pliable acrylic materials and are worn over the upper or lower teeth. Although commonly linked to managing teeth grinding and 表参道 歯科矯正 TMJ discomfort, their use in orthodontic care extends beyond symptom relief.

A primary rationale for prescribing occlusal splints is to diminish the forces from bruxism and jaw clenching that can occur during orthodontic treatment. During active tooth movement with brackets or clear aligners, they are at higher risk for mechanical stress. Splints serve as a protective barrier, eliminating enamel-on-enamel friction and preserving tooth structure. This is especially helpful for patients who have a history of nighttime grinding or who suffer from stress-induced parafunction.
