INVESTIGATION OF INFLUENCE OF VARIOUS TEETH PREP ALGORITHMS ON OUTCOMES OF PROSTHETIC TREATMENT
Teeth prep is an integral step in dental prosthetic treatment with fixed dentures. Making of a ledge of enough breadth and stable geometry, its correct relationship with the marginal periodontal tissues are among the key requirements of teeth prep for metal ceramic crowns. The quality of the ledge largely depends on the set of used tools. The authors have developed a set of dental diamond burs “Start” to prepare teeth for metal ceramic crowns. The article presents the results of clinical approbation of the developed set of burs for teeth preparation for metal ceramic crowns. The authors have carried out the comparative study in parallel groups. In the experimental group teeth preparation was performed using the developed set of burs “Start”, in the control group the teeth were prepared with traditional technique. This research is dedicated to finding the relationship between the applied set of tools, quality of the made ledge, the accuracy of fit of crowns in the region of the ledge, the state of marginal periodontium after prosthetic treatment. The obtained data testify to the impact of the used set of burs for teeth prep on the quality of dental prosthetic treatment with fixed dentures. Comparative analysis of clinical efficiency of differential algorithm of teeth prep for crowns was carried out according to the following criteria of the quality of prosthetic treatment: completeness and correctness of execution of medical procedures, the absence of iatrogenic complications, the quality of workmanship of denture.
