Exclusion criteria
Exclusion criteria: Patients under 18 years of age, edentulous patients or patients treated with removable dentures, no presence of bruxism or other nocturnal parafunctions of the jaw, arthropathy of the temporomandibular joints requiring treatment, dental treatment required during the study period - with the exception of tooth cleaning, lack of consent and data protection declaration, participation in the planning and implementation of the study, Presence of alcohol or drug abuse, Uncontrolled pathological processes in the oral cavity, Mental or psychosomatic illness that would affect participation in the study and compliance with the study protocol.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Wear of the splint material: The wear is recorded by means of a surface scan after the test wear and after 3 and 6 months of wearing. The surfaces are scanned with high-precision scanners (GOM Atos 135, GOM Metrology, Braunschweig). Wear is determined by superimposing the scans and using the GOM Inspect analysis software. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Resistance to discoloration: The resistance to discoloration is assessed with overhead photography under standardized conditions after the test wear and after 3 and 6 months of wear and by a blinded rater in a direct comparison of the two materials. Photographing is carried out under standardized conditions, the camera body EOS 90D from Canon, the flash Macro Flash 18 from Nissin and the macro lens 105mm F2.8 EX DG Macro OS from Sigma. The standardized settings ??are aperture F20, exposure time 1/200, sensitivity ISO 200, flash ETTL. The color values ??are then calibrated and objectified. As a uniform background, the same black background is used for every shot. The lighting conditions and white balance are uniformly calibrated using a gray card. 2. Wearing comfort: The wearing comfort is evaluated in a direct comparison of the two materials using questionnaires after 3 and 6 months of wearing. In addition to the standardized questionnaires PHQ-9, HADS-D, stress load according to Ahlers/Jakstat, Bruxism Screening Index (BSI) and OHIP, questionnaires on wearing comfort and subjective evaluation of the splint materials are used. | — |
