B-Splint

A B-Splint — an anterior midpoint contact splint (muscle deprogrammer) for quick harmonisation of muscular disorders. It reduces temporalis, masseter and lateral pterygoid parafunctional activity, disengaging the posteriors during clenching. Often prescribed for TMJ.

How a dental deprogrammer works

The B-Splint is an anterior midpoint contact splint — a muscle deprogrammer. By allowing only a single point of contact at the front of the mouth, it interrupts the habitual bite and lets the jaw muscles release the pattern they have learned to hold.

  1. A single point of contact

    The splint presents one small, smooth acrylic platform behind the upper front teeth. Only the lower incisors meet it — every back tooth is held slightly apart, so the posterior teeth never touch.

  2. Posterior feedback switches off

    Clenching and grinding are driven by proprioceptive feedback from the way the back teeth interlock. With the posteriors separated, that input stops — and the brain no longer has a familiar bite position to clench into.

  3. The muscles deprogram

    A single anterior contact cannot transmit heavy load, so the masseter and temporalis can no longer brace the way they do on a full bite. Over minutes of wear — and more so over days — the elevator muscles relax and the parafunctional habit fades.

  4. The jaw seats in centric relation

    Freed from the memorised occlusion, the condyles settle into their seated position in the joint. This reveals the true jaw relationship — valuable before restorative or occlusal work, and settling for muscular pain and TMD symptoms.

Good to know — because an anterior-only appliance holds the back teeth apart, the B-Splint is intended for short-to-medium-term, supervised wear rather than indefinite full-time use. Follow your usual review protocol to guard against posterior over-eruption.
