ABSTRACT
Statement of problem
Although high survival rates of implant-supported fixed partial dentures (ISFPDs)
have been reported, evidence for complications, failures, and factors that interfere
with their longevity is lacking.
Purpose
The purpose of this scoping review was to review the literature to investigate the
most common failures and complications of ISFPDs.
Material and methods
This review followed the preferred reporting items for systematic reviews and meta-analyses
scoping review (PRISMA ScR) guidelines, and the methodology was registered on the
open science framework (osf.io/5xqkp). An electronic search was conducted in PubMed/MEDLINE,
Embase, Cochrane Library, Scopus, and Web of Science databases and nonpeer-reviewed
literature for articles published from 2013 to January 2023. Studies that evaluated
the clinical performance of ISFPDs with at least 1 year of follow-up and described
the concepts of failure and success were included.
Results
The search yielded 5695 studies. Fourteen articles were included in this review for
data extraction. Veneering porcelain fracture, screw fracture, and implant loss were
the most common failures reported. Technical complications mainly involved screw loosening,
loss of retention, and wear of the screw-access restoration.
Conclusions
Bruxism, mismatch of the thermal expansion coefficient, unsatisfactory support of
the framework, choice of cement, shape of the titanium abutments, and extended length
of the cantilever were associated with the longevity of the ISFPD. Despite the high
survival rate of ISFPDs, data must be carefully interpreted because of the variation
in the materials used to manufacture the ISFPD and the heterogeneity of the studies
in this review.
