Which splint is used to reduce muscle activity and provide temporary relief?

• A. NTI splint
• B. Full-arch splint
• C. Mouthguard
• D. Bite plate

Answer: (A)

The key idea is how a splint can decrease jaw muscle activity to relieve symptoms. The NTI splint is an anterior bite appliance that sits on the upper front teeth and prevents contact of the back teeth. By blocking posterior occlusion and limiting how hard the jaw can clench, it reduces the force the jaw muscles must generate. That drop in clenching force leads to less muscle activity and provides quick, temporary relief from muscle strain and related pain. It’s intended for short-term use to break the cycle of clenching, rather than to stabilize the bite or protect all teeth long-term. Other options either aim to stabilize the bite across all teeth (full-arch splint) or protect the teeth without actively reducing muscle activity (mouthguard, generic bite plates), so they don’t target the neuromuscular reduction as specifically as the NTI splint.
