ABSTRACT

The use of ceramic prosthesis for the replacement of missing teeth has become abundant in recent years due to its aesthetic appearance. Certain factors that contribute to failure of the ceramic prosthesis can be broadly divided into 3 - biological factors, mechanical factors and aesthetic factors. The dental professional and dental technician should pay a great deal of attention to all these aspects in order to preserve the longevity of the prosthesis. The aim of this study is to determine the failures associated with existing ceramic prosthesis. This was a comparative, descriptive study, where the data of the patients who reported to the dental clinics in saveetha dental college, Chennai, India, was obtained from the dental information archiving software (DIAS). Data was collected and tabulated. The collected data was further analyzed, recorded in microsoft excel software and was subjected to statistical analysis using IBM SPSS statistics analyzer. The total sample size of the current study was 26 cases. In this study, the ceramic prosthesis was analysed for defects and failure associated with the ceramic prosthesis. Satisfactory results demonstrating defects and failure of the prosthesis were obtained. Most commonly reported old prosthesis were of the metal ceramic type. Ceramic fracture was the major observation of the present study following which secondary caries, marginal integrity and discoloration were observed.
