Dual Bite

  1. Difference between jaw joint bite and tooth bite
    1. Teeth control muscles to protect teeth
    2. Jaw joint wants power control muscles to full seat joint-relax muscles
  2. Definitions:
    1. Tooth bite is maximum interdigitation teeth
    2. Jaw joint bite is fully seated condyles in fossa
  3. Control of chewing muscles = “muscle guarding”
    1. Teeth controll muscles to go into tooth proctected bite
    2. Jaw joint tries order muscles to allow fully seated condyles
    3. There are teeth in way to full seat condyles
    4. So conflict erupts between muscle controlls
    5. This muscle guarding by both controllers increases muscle inflammation
  4. Muscle overuse or over contraction contributors
    1. Joint laxity = hypermobility = dual bite
    2. Tooth position does not allow full seat joint
  5. Orthotic allows full seat jaw joint w/o teeth interfering w/ the jaw joint need fully seat
  6. Who has dual bite?
    1. 85 % no dual bite
    2. 10 % small dual bite
    3. 5% moderate dual bite
  7. Great difference Dual Bite, the greater muscle activity
