WAYS TO IMPROVE THE EFFICACY OF ORTHOPEDIC TREATMENT OF PATIENTS WITH SEVERE EXCESSIVE TOOTH WEAR

Excessive tooth wear is currently one of the main problems of oral health. Excessive tooth wear affects both function and aesthetics. Teeth with excessive tooth wear cannot be effectively used for biting and chewing food. Treating excessive tooth wear is complex and time consuming. Studies on increasing the effectiveness of treatment of such patients are relevant. The study involved 60 people with a significant degree of excessive tooth wear and a decrease in the height of the bite. We examined patients using measurements of the electromyographic (EMG) activity of mm.masseter and temporalis. The subjects were divided into two groups - in the first group (30 people), the maxillofacial system was prepared for further prosthetics by wearing a removable dental splint-teethguard, in the second group (30 people) we used both removable splint-teethguards and transcutaneous electrical nerve stimulation (TENS). In both groups, an electromyographic study of mm.masseter and temporalis was performed after 1 week, 1 and 2 months of treatment. In patients with excessive tooth wear and a significant decrease in bite height, our method of preparation for orthopedic treatment contributed to a more rapid normalization of mm.masseter and temporalis functions. The results indicate a pronounced positive effect of the use of removable teeth guard and TENS on the normalization of the bioelectric activity of the masticatory muscles in the preparation of patients for orthopedic treatment of excessive tooth wear.
