Investigation of the effect of fixing zinc-phosphate cements on the tissues surrounding a fixed denture structure

Abstract

Despite the rapid development of orthopedic dentistry and the release of a large number of materials used to fix fixed structures, it is impossible to single out among them an ideal one for every case. There are several classes with significantly different characteristics. Even representatives of the same group have significant differences in properties, which is associated with continuous work on the recipe to adapt to modern requirements. Every orthopedic dentist tries to choose for himself a material that satisfies all parameters, used in dental practice as a fixing fixed structures. He pays special attention not only to the convenience of working with cements or their physico-chemical, physico-mechanical properties, but also to its bioinertness and biocompatibility. To assess the effect of fixing materials on surrounding tissues, a comparative assessment was carried out with the measurement of the toxicity index of materials and the papillary-marginal-alveolar index (PMA).
