ABSTRACT
Statement of the Problem: Cementation failure is one of the most common complications associated with the long term function of implant supported fixed restorations. However, the rate of failure and longevity of restorations luted with permanent and provisional cements against cementation failure remains unclear. Aim: The aim of the systematic review was 1) To evaluate the long term rate of cementation failure in implant supported fixed restoration luted with provisional luting cements. 2) To evaluate the long term effectiveness of permanent luting cements VS provisional luting cements in implant supported fixed restorations against cementation failure Search Methodology: Review of literature published up to July 2011 in the PUBMED was conducted to recognize clinical studies involving implant supported fixed restorations. The search methodology followed was a combination of Mesh terms and suitable key words. Thirty-two (32) studies met with the inclusion criteria. Studies were further divided into two categories: 15 short term clinical studies with an observation period of less than5years and more and 17 clinical studies with an observation period of 5 years and more. Results: For the primary outcome of cementation failure, the data extracted revealed 713 implants were placed in that 400 were single crowns luted with permanent cements. The mean weighted percentage for cementation failure was calculated to be 25.50% more than 5 years. (CI = 95% [21.23-29.73]. Out of 880 implants 319 implants were luted with provisional cements. The mean weighted percentage for cementation failure was 12.66%. (CI = 95% [9.35-15.97] Out of 59 fixed cantilever prosthesis in that result showed cementation failure rate of 5.08% with both permanent and provisional restoration. Out of 488 implants, 212 multiple restorations were placed and luted with permanent cements and mean rated percentage for failure rate was 40.57%.Out of 158 implants, 68 multiple restorations were placed and luted with provisional cements and mean percentage for failure rate was 10.29%. Conclusion: This review concluded that there was no difference in longevity of restorations luted with provisional and permanent cements in implant supported fixed restorations over a period of more than five years. Further research involving standardised long time prospective trials and randomized control clinical trials will provide more valuable information to this issue.
