Abstract
The aim of this study was to perform an analysis of the incidence of implant body
fracture and to identify possible risk factors. A long-term follow-up retrospective
evaluation of 3477 patients who received 8588 implants from five implant systems was
performed. Overall, 2810 patients who received 7502 implants, with an average follow-up
of 6.9 years, were included in the analysis. The overall body fracture rate was 0.49%
(37/7502), among which 32.4% (12/37) were implants with a reduced diameter. The estimated
cumulative fracture rate was 1.24%. Fractures were observed in two patients with three
Brånemark implants, 13 patients with 15 Nobel Replace implants, eight patients with
eight Camlog implants, eight patients with 11 Ankylos implants, and none of the patients
with Thommen implants. Most fractures occurred in the molar region (29/37) and in
single implant-supported restorations (30/37). The results showed significant differences
between splinted and unsplinted restorations (P = 0.005) and between regular and narrow diameter implants (P = 0.009). Within the limitations of this retrospective analysis, a narrow implant
diameter is a potential risk factor for implant body fracture in the posterior region.
Furthermore, unsplinted restorations appear to be associated with a higher rate of
implant fracture.
