| Abstract [eng] |
Restoring tooth loss with the help of a dental implant is a modern treatment method, but one of the failures of this treatment is the reversal of the implant screw, causing the patient's dissatisfaction, the need for additional work by a dentist and the work of the dental laboratory and expenses of the work. In this work, the dental implant screw tightening characteristics are studied. Under the experimental conditions, different implant screw tightening is performed, differences in these actions are evaluated trying to create the best possible tightening of the screw to reduce the number of complications of this treatment. Aim of the work: to analyze the abutment screw torque tightening parameters and identify criteria which can influence to the screw loosening in dental implant. In this work it is compare different types of dental implant tightening, examine the possibilities of evaluating tooth implant tightening with different parameters taken from the tightening torque rotation curve. In this work are performed dental implant torque tests, they are compared with each other, the results are analyzed. The possibility of turning the screws not according to the torque, but according to the angle of rotation of the screw was evaluated. Following the tests, there was a tendency for the implant to be counter clocked by using springs designed to simulate the gums, which has a lower clamping angle and higher speeds than without the use of springs. This is determined by the physical laws, because the implant catches the thread faster. Based on these data, it can be concluded that the tightening of the implant screw according to the torque is possible, but more detailed and longer tests are required. |
