The Optimal Type of Prosthesis Based on A Comparative Assessment of The Impact of Cermet and Zircon Prostheses

Abstract

     In the modern world, the loss of one or more teeth as a result of dental diseases is one of the serious problems of the healthcare system, since it leads to a decrease in the quality of life of the patient, which  leads  to  various  diseases.  According  to  an epidemiological  study  by  the  World  Health  Organization (WHO),  partial  or  complete  absence  of  teeth  due  to  injuries, caries and periodontitis is observed in 75% of the population in different regions of the world." According to some authors, the proportion  of  complete  occlusive  defects  increases  with  age. Often, in the absence of one or more teeth, treatment is carried out with conventional portable prostheses or bridge prostheses with  a  base  in  the  formed  teeth.  The  need  for  orthopedic treatment remains high:  from 30.3% in the age group of 20-29 years to 68.1% in the age group of 50-59 years." In turn, the high frequency of patients with dentition defects requires the speedy  solution  of  such  social,  physiological,  aesthetic  and psychological problems.
