Objective: The aim: Determination of the factors complications occurrence in prosthetics with metal-ceramic prostheses.
Patients and methods: Materials andmethods: Clinical, cytological, cytochemical methods and methods of statistical processing of the received data are applied.
Results: Results: A number of factors with different degrees of significance have been identified, which in the dynamics of clinical observations of the percentage of absorbed dispersion are decisive in the development of changes in the gums. At the stage of odontopreparation - the 1 factor, with the percentage of absorbed dispersion (12,3%) - preparation. The 2 factor - (11,9%) - traumatic. The 3 factor, periodontal, was slightly less significant (9,8%). In the dynamics of clinical observations for 45 days in the first place was the dissecting factor - (14%). The second most important factor was the vitality of the teeth - (11,5%). The 3 factor remained relatively stable - periodontal (8,5%). In the dynamics of clinical observations after 1 year, a redistribution of significance was noted. The largest percentage of absorbed dispersion covered periodontal factor - (15%). Vitality factor - (11%). Slightly lower, but clinically significant, of (8%) absorbed dispersion, was the preparation factor.
Conclusion: Conclusions: Statistical analysis of the studied parameters made it possible to determine the key factors for predicting their development and diagnostics, it is important for organizing an increase in the effectiveness of orthopedic prophylactic therapeutic measures at the stages of restoration of dental hard tissues.
