Comparative Study of Maxillary and Mandibular Splints Used for the Treatment of Masticatory Muscle Parafunction (FEA)

Single-group, Comparative Biomechanical Study of Maxillary and Mandibular Splints Used for the Treatment of Masticatory Muscle Parafunction

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

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.

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
