A systematic review of the survival and complication rates of fixed partial dentures (FPDs) after an observation period of at least 5 years

Abstract

Despite a high survival of FPDs, biological and technical complications are frequent. This, in turn, means that substantial amounts of chair time have to be accepted by the clinician following the incorporation of implant-supported FPDs. More studies with follow-up times of 10 and more years are needed as only few studies have described the long-term outcomes.

Biomechanical evaluation of internal and external hexagon platform switched implant-abutment connections: An in vitro laboratory and three-dimensional finite element analysis

“…Since the main challenges in the development of implantabutment connection designs comprises reducing the incidence of mechanical failures while improving the interface between soft tissue and implant-abutment junction [31,32], the evaluation of reliability and failure modes supported by evaluation of stress distribution in each component of platform-switched connections may provide insight into the mechanical behavior of different configurations of implant-abutment connection. Therefore, the present study sought to assess the effect of abutment's diameter shifting (regular and switched-platform) on reliability and failure modes of anatomically correct maxillary central incisor crowns varying the geometry of implant connection (internal and external hexagon).…”

Ten-year survival rate for cantilevered fixed partial dentures

“…This systematic review is the final one following three other reviews [1][2][3] by the same group looking at the survival and complication rates of different designs of FPD. The title of the series is slightly misleading in suggesting that the data reflect a minimum of 5 years of observation, whereas the inclusion criteria for study selection in fact required a mean follow-up time of 5 years or more.…”

“…Although it is likely that cantilevered designs are chosen for what are thought to be less-stressed environments, these success rates are lower than those for conventional FPD designs. 3 This too should be considered when treatment planning options are available.…”

Prosthodontic complications associated with implant retained crowns and bridgework: a review of the literature

“…[3][4][5][6][7] However, these reviews have also identified a variety of complications that may be associated with these prostheses. [2][3][4][5][6][7] Although these complications rarely result in the complete failure of treatment, their management can be frustrating, expensive and time consuming for the patient, clinician and technician. This review discusses the incidence, aetiology, prevention and management of common prosthodontic complications, which may occur following the delivery of implant retained crowns and bridgework.…”
