Features of comprehensive rehabilitation for secondary dental deformations as a result of the carious process and dental alveolar lengthening of the antagonist tooth

Abstract

Among the most common diseases of hard tissues of teeth, leading to the development of deformations of the dentition and occlusion, are caries and its complications (significant destruction of the crown part of the teeth, damage to groups of teeth with multiple caries, chipped walls, tooth extraction). With a carious lesion, the anatomical shape of the crowns of the teeth changes, and all surfaces of the tooth can be damaged, which leads to the development of pathological processes in the periodontium of the teeth and deformation of the dentition and occlusion. When restoring small defects in the occlusal surfaces of the posterior teeth in the cavities of the first class, the presence of cement fillings does not affect the geometry and area of the occlusal contacts. But with a significant loss of dental tissues, when IROPZ ≥0.5, as well as in the cavities of the second class according to Black, the presence of cement fillings significantly changes the localization and area of the contact points of the chewing teeth, in some cases completely excluding the tooth from occlusion.
