RESUMEN
The object of the paper is a clinical assessment of the resin-bonded fixed partial dentures (RBFPD) produced by the indirect method of dental composite resin materials with various reinforcement, in patients with I degree high teeth abrasion. 80 persons with I degree high teeth abrasion and small defects in the lateral part of dental arch with a length of not more than one tooth were examined. For patients of I group, 40 RBFPDs were made of nano dental composite resin and three glass fiber tapes laid horizontally; for patients of II group, 40 RBFPDs made of hardened nano dental composite resin were reinforced with the same tapes laid by the developed method. In 12 months, fractures and fixation disorders of 9 dentures were found in patients from I group (22.5% of the initial quantity), and patients of II group had fixation disorders in 2 dentures (5.0%), and 7 (17.5%) and 32 dentures (80.0%), respectively, had no significant and insignificant disorders. In 24 months, the patients of I group had fractures and fixation disorders of another 7 dentures (22.6% of the number of RBFPDs at a given time), and patients from II group had such disorders in 3 RBFPDs (7.9%), while 3 dentures (7.5% of the initial amount) and 22 RBFPDs (55.0%), respectively, had no disorders. In order to restore the dental integrity with small bounded edentulous teeth in patients with I degree high teeth abrasion, it is possible to use RBFPDs indirect production of which requires the application of hardened nano dental composite resin with reinforcement by means of three glass fiber tapes according to the developed method, which ensures restoration efficiency within 12 and 24 months at the level of 80.0% and 55.0%.
