Brief summary
the purpose of this study is to clarify the rationale for the choice of the upper or lower jaw for positioning the occlusal splint
Detailed 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.
Interventions
DEVICEOcclusal splint
Occlusal splints are hard, made of polymer biocompatible material using digital additive technology.

Intervention model description
patients are included in a single study group. In a study group, each patient is assessed for both of the same primary treatment. The final results for each of the treatments for each patient are used for further analysis by the finite element method.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Difference between mandible and maxilla of occlusal splints in terms of stress-strain state and magnitude of displacement of the splinted teeth | during one appointment, up to 2 hours | By means of the final elemental analysis, data on the stress-strain state (in MPa) and the displacement of the splinted teeth (in mm) will be obtained, individually for each patient. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Difference between mandible and maxilla dentition in terms of stress-strain state and magnitude of displacement of the teeth | during one appointment, up to 2 hours | By means of the final elemental analysis, data on the stress-strain state (in MPa) and the displacement of the teeth (in mm) will be obtained, individually for each patient. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Measurement of the influence of the occlusal splint use on the indicators of the stress-strain state and the magnitude of tooth displacement | during one appointment, up to 2 hours | By means of the final elemental analysis, data on the stress-strain state (in MPa) and the displacement of the teeth (in mm) will be obtained, individually for each patient. |
