Methods: Patients who had been fitted with a Brånemark or Replace implant in ourclinic between January 1997 and October 2012 and who were recalled between October 2011and October 2012 (1₅8 patients, 4₅8 implants) were investigated to determine the causes ofdefluxion of their implants and 10 potential related factors. Results: Defluxion occurred in a total of 19 of the 4₅8 implants (4.1%), ranging from asearly as 26 days post–insertion in an unloaded implant to as late as 4,269 days post–insertionin a case of implant fracture. Univariate and multivariate analysis revealed a greaterincidence of implant defluxion among men compared to women (P = 0.022), and a significantlygreater incidence for implant overdentures compared to simple prosthetic designs,such as crowns, linked crowns, and bridges (P=0.004). Conclusion: The present findings reaffirmed aspects of dental implant fitting that requireattention in clinical practice to ensure longevity, particularly prosthetic design andfitting method, as well as the effects of smoking. However, a multicenter survey is requiredto provide further evidence and support these findings.}, pages = {91--104}, title = {当施設における15年間のインプラントの脱落原因に関する解析}, volume = {40}, year = {2014} }
