Retrospective Study for Survival Rate of Implant Supported Zirconia Fixed Prosthesis
Deepak Goyal, Ranjana Balla, Shuchi Gupta, Ritesh Gupta

Background: Zirconia has been used in dentistry for around 15 years for different indications, with a primary aim on replacement of metal to improvise esthetics. Therefore,  the  main aim  of  this  clinical study was to retrospectively evaluate the survival outcomes of titanium based dental  implants  and  the  survival  of  zirconia complete-arch fixed prosthesis. Materials and methods: The present retrospective study consisted of patients that were treated between the last 3 years with titanium dental implants and zirconia prosthesis. The fit of each prosthesis was established by visual,   radiographic,   and   tactile tests.   Patients were followed up for 3-4 months for any complications or routine oral hygiene checkups. All the failures and complications were recorded amongst the subjects for 4-year period and recorded in a tabulated form. These were analyzed statistically using SPSS software. Results: For first year the interim survival rate was 99.07%, for second year it was 99.6%, during third year it was 99.63%.  There was only 1 prosthesis failure during the first year and for the rest of the years the interim survival rate was 100%. There was one failure in first year leading to the interim survival rate of 99.48%. In the second year there were 3 failures giving the interval failure rate of 97.7%. The interim survival rate was 100% for the rest of the years. Conclusion: In the present study, the zirconia prosthesis offered a great survival rate of more than 95% in a four year duration.
Key words: Implants, prosthesis, zirconia.
