Results of a study of zinc-phosphate cements for fixation of fixed orthopedic structures under the influence of material hardening time

Abstract

Patients often prefer non-removable prosthesis designs to replace dental row defects, given their undeniable benefits. However, there is a possibility of developing complications during prosthetics, it is impossible to completely exclude medical errors and errors of the dental technician.
 Dentists know that in 20% of cases, prosthetics with non-removable types of prostheses end unsuccessfully due to errors in treatment, as well as improper use of fixing cements at the stage of storing the prosthesis. About 20% of cases are complications in the near future after prosthetics during the operation of the prosthesis. The proportion of complications due to carious tooth damage under prostheses can reach more than 49%.
 Non-removable prostheses, firmly fixed by zinc-phosphate cements, gain a number of advantages by choosing this particular material: a slight percentage of shrinkage; low percent solubility; increased strength; creation of a holding layer between tissues of the oral cavity and a selected type of prosthesis.
 Our study is devoted to the issues of assessing the most significant qualities of fixing cements, which is of great practical importance.
