Abstract
Introduction:
Resin bonded fixed dental prostheses (RBFDPs) have been available in dentistry for nearly 40 years since its introduction in the 1970s and is an accepted alternative for the replacement for a single missing tooth. Functional longevity, however, has always remained an issue with these types of restorations demonstrating frequent incidences of debonding leading to complete failure of the intended therapy. There have been clinical studies which demonstrate that a cantilevered design (Cantilevered Resin bonded fixed dental prostheses CL-RBFDPs) in such restorations exhibit lesser chances of failure of restorations.The objective of this review was to evaluate the Success rates and Debonding rates of conventional and cantilevered resin bonded fixed dental prostheses.
Materials and Method:
Search strategy-A literature search was conducted using a combination of electronic search engines such as PUBMED (U.S. National Library of Medicine, Bethesda, MD, USA), referencing relevant titles and citations and manual searching of journals for identifying studies which evaluated conventional RBFDPs and cantilevered RBFDPs and reported on the success rates and debonding rates of these two types of restorations. The electronic search was conducted without any date restrictions. Selection of Studies - Eligibility criteria included human studies and excluded any reviews, case reports and in vitro trials. The publications’ intervention had to have been both conventional and cantilevered RBFDPs for replacement of missing teeth. Data extraction- Data were extracted from the final studies according to a customised data collection form. The outcome measures success rates and debonding rates of the restorations.
Results:
The search strategy yielded a total of 30 articles. Abstract analysis performed for these articles augmented with hand searching of journals resulted in 6 studies which met the inclusion criteria formulated for this review. The prospective and retrospective studies obtained were analysed and the most common complication for these types of prostheses were found to be debonding irrespective of design, choice of material or luting system, or preparation design followed by a fracture of retainers. Survival rates were also provided in a few of these studies. The cantilevered RBFDPs appear to demonstrate a lower incidence of debonding, and fractures compared to conventional RBFDP
Conclusion:
Further well designed randomised controlled trials with long term follow up are required to provide higher levels of evidence for this treatment modality. However, based on all the studies currently available the overall incidences of debonding appear to be lesser when cantilevered RBFDPs were provided. Hence, we are able to conclude that Cantilevered RBFDPs are an acceptable alternative to conventional RBFDPs with lower incidences of complications resulting in improved clinical performance.
