About this trial

This is an interventional basic science trial for Jaw, Edentulous focused on measuring Denture, Complete, Technology, Dental, Biomedical and Dental Materials

Eligibility Criteria

18 Years - 50 Years (Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • continuous dentition
  • diagnosis (by ICD*-10): K03.0 Excessive attrition of teeth
  • diagnosis (by ICD-10): K07.6 Temporomandibular joint disorders
  • complaints of nocturnal bruxism
  • complaints of discomfort in the area of the chewing muscles
  • no history of orthopedic and / or orthodontic treatment
  • absence of concomitant general somatic pathologies in the stage of decompensation
  • no history of psychogenic and psychosomatic disorders
  • no history of cancer *ICD - Classification of Diseases

Exclusion Criteria:

  • refusal of the patient during the clinical trial from further treatment

Sites / Locations

  • A.I. Yevdokimov Moscow State University of Medicine and Dentistry

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Occlusal splints

Arm 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.

Outcomes

Primary Outcome Measures

Difference between mandible and maxilla of occlusal splints in terms of stress-strain state and magnitude of displacement of the splinted teeth
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 Outcome Measures

Difference between mandible and maxilla dentition in terms of stress-strain state and magnitude of displacement of the teeth
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.

5. Study Description

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: "maxillary occlusal splint - lower dentition"; "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.
