Details and patient eligibility

About

the purpose of this study is to clarify the rationale for the choice of the upper or lower jaw for positioning the occlusal splint

Full description

After being informed about the study and potential risks, all patients are giving written informed consent. Occlusal splints for the upper and lower jaws are made for each of the patients. An assessment is made of the relative values and distribution of chewing forces in two cases:

1. "maxillary occlusal splint - lower dentition";
2. "mandibular occlusal splint - upper dentition". The obtained values are used in the final elemental analysis of the stress-strain state and the degree of displacement of the dentition in both indicated cases.

Occlusal splints

Experimental group

Description:

In a clinical setting, participants test the closure of the occlusal splint with the antagonistic dentition. Only one of the two occlusal splints (mandibular splint and maxillary splint) is used at a time. Occlusal splints are applied separately and alternately.
