Prevalence Of Ceramic Failure Among Fixed Dental Prosthesis

Abstract

Fixed Partial Prostheses (Fpds) Have Been Successfully Used For More Than Four Decades. These Prostheses Are Considered A Reliable And Long Lasting Device In Oral Service, Porcelain Fracture Associated With An Implant-Supported, Metal Ceramic Crown Or Fixed Partial Denture Occurs At A Higher Rate Than In Tooth-Supported Restorations, According To The Literature. Clinical Data On Survival Rates Reveal That All-Ceramic Dental Prostheses Are Susceptible To Fracture From Repetitive Occlusal Loading.The Aim Of The Study Is To Evaluate The Prevalence Of Ceramic Failure Among Fixed Dental Prosthesis.A Cross Sectional Study Was Conducted From June 2019 To March 2020. Patient Records Were Collected And Evaluated. Patients Having Ceramic Failure With Respect To Their Fixed Dental Prostheses Were Selected For The Study. The Most Common Cause Of Ceramic Failure In Fixed Partial Denture Was Found To Be Fracture Of Ceramic Veneer In  Prosthesis. (79.4%) Followed By Unaesthetic Prosthesis (9.5%) Discolouration Of Prosthesis (7.9%), And Worn Out Prosthesis (3.2%). The Prevalence Of Ceramic Failure Was Present More In Females As Compared To Males Within The Limits Of The Present Study, It Can Be Concluded That The Most Common Type Of Ceramic Failure Is  Fracture Of Ceramic Veneer  Which Is  More Prevalent In Females Rather Than Males
