Abstract
The aim — to develop objective screening methods for predicting complications of dental implantation, which have high sensitivity and specificity to provide the necessary preventive and therapeutic measures to improve the efficiency of the selected protocol for early functional loading. Materials and methods. Implantation using the protocol of early functional loading was performed in connection with the loss of the 4—7th teeth of the upper and lower jaws. The study participants underwent the installation of Thommen Medical (27 implants), Astra Tech (26 implants) and Konmet (7 implants) conical and cylindrical shapes. The primary stability was measured with an Osstell resonance frequency analyzer (Sweden). Results. The primary stability of implants installed in the upper jaw is lower than in the lower one due to the anatomical features of the jaw. From the obtained results of the Torque/ISQ analysis, conical implants have an advantage in the upper jaw, and cylindrical ones in the lower jaw. Conclusions. A mathematical model has been developed that describes the dependence of the initial results of determining the torque and ISQ during the operation and subsequent failure of the functioning of dental implants. When installing dental implants, an assessment of the primary stability of implants and the use of a mathematical model to identify risk groups should be included in the operation protocol. The development and implementation of models for predicting the outcomes of dental implantation contributed to the choice of the correct tactics for the timing of orthopedic treatment, an increase in the life of implants and an improvement in the quality of dental care for patients.
