Equilibration





We at Perfect-32, strive to achieve equilibration for patients suffering from jaw joint pain or muscle fatigue. The term equilibration literally means to establish balance or equality. The importance of equal forces on the teeth is intuitively easy to understand. If only a few teeth engage when a person bites together, those teeth will endure much more force than they are structurally able to withstand. They will wear excessively (a condition called attrition), chip, crack, or the patient will (often subconsciously) continuously move their jaw in an attempt to locate a position where the forces are more in balance. Unfortunately, repositioning the jaws to provide balanced force distribution on the teeth may not be possible for the patient, due to crowding or misalignment of the teeth. The problem of poorly distributed bite forces on the teeth is magnified if teeth are lost. The patient's jaw muscles may become fatigued (myalgia) by continuously trying to achieve a position of balanced force distribution on the teeth. The muscles may also become painful. The patient may chronically brux (grind) their teeth until they wear the teeth into a position of more equal force distribution. The jaw joints themselves may be the weak link and develop popping, clicking, grating (crepitus) or pain from the unequal balance of forces. Collectively, these symptoms represent various stages of temporomandibular joint (TMJ) dysfunction, or TMD. We adjust the way the teeth mesh such that when the jaw muscles are at rest and the jaw joints are in a stable, neutral position, the teeth are engaging uniformly with equal contacts between the upper and lower teeth to achieve equilibration in regard of the jaw joints, jaw muscles and teeth (the stomatognathic system). The temporomandibular joints (i.e. the jaw joints) are not pure hinge joints like knees or elbows. Instead, only the first 15 degrees or so of opening is rotational (hinge). With further opening, the lower jaw begins to slide along the skull base until it reaches the maximum opening. It is the only joint like this in the body. In order for this type of motion to be possible, we free the mandible (lower jaw) to move in all three dimensions (forwards, backwards and side-to-side).
