Abstract

The aim of this study is to assess the quality of posterior teeth restorations in to identify the iatrogenic cause of primary traumatic occlusion.
Materials and methods.
306 participants with physiological bite were examined. They were separated into 4 groups according to iatrogenic factors: unacceptable posterior restorations, 3-rd molar affection, combination of these factors.
Results.
Only 45 (14.7%) people did not have symptoms of primary traumatic occlusion, all the other examined (261 people, or 85.3%) had violations of occlusal relief of posterior teeth of various origins. It was found that 76.5% of fillings did not meet clinical requirements, in most cases due to poor representation of occlusal surface, contact point, presence of a marginal gap. It can be explained that many dentists do not pay attention to morphology of occlusal surface and correct relation with antagonists. The most common symptoms of primary traumatic occlusion were: hard tissue abrasion facets, enamel cracks, wedge-shaped defects, changes in the gingival margin and periodontal pockets, supracontacts on the working or balancing sides.
Conclusion.
 Authors considered that iatrogenic unacceptable occlusal relief should be interpreted not only as a mistake, but also as a potential cause of severe dental diseases in long term.

Key words:

iatrogeny, occlusion, occlusial-articulatory relations, primary traumatic occlusion, supracontacts, prophylaxis of dental diseases
