We usually do bite or myorelaxant splints on patients, who present strong occlusal wears caused by grinding (bruxism) or on clenching patients or with light muscular troubles and on dysfunctional patients.
The bites are real
functional devices whose main purpose is to correct the mandible dislocation positioning it in a correct therapeutic position;
the clinician establishes that position with specific tests (axiography) and he can set it with the help of the repositioning waxes or using the CPM
in not dysfunctional cases, where it’s sufficient to know the condylar housing inclination, but not the complete path.
The bite can be a real “orthopaedic” appliance in patients with problematic cases, where it can be necessary to capture the joint disc or to remove an asymptomatic and symptomatic joint clicking.
Thanks to the information get from the clinician, the laboratory can set the articulator with individual values and realise a precision bite
A bite should have the following characteristics:
. Occlusal stability . Correct occlusal contacts . Canine guide . Protrusive check . The front sector must touch lightly the antagonist.
Normally I prefer to do lower bites for patient’s comfort and small dimension, but it doesn’t exist a real rule that shows us to work only on the lower maxillary.
