Abstract

<abstract abstract-type="main" id="clr12439-abs-0001"> <title>Abstract</title> <sec id="clr12439-sec-0001" sec-type="section"> <title>Objectives</title> <p>Rehabilitation with implant‐supported fixed prostheses is a predictable modality to restore lost function and esthetics; however, fixed restorations are subject to biological and prosthetic complications, which may represent a problem in the long‐term. The aim of this study was to evaluate the long‐term survival and complication rates of fixed restorations supported by Morse‐taper connection implants.</p> </sec> <sec id="clr12439-sec-0002" sec-type="section"> <title>Materials and Methods</title> <p>Between January 1992 and December 2002, 49 patients (age range 22–70 years), were included in this study. The restorations involved 58 fixed reconstructions (15 single crowns [SCS], 29 partial prostheses, 14 full‐arches), supported by 178 Morse‐taper connection implants with a follow‐up ranging from 10 to 20 years. Outcomes such as implant survival, marginal bone loss, frequency of biological and prosthetic complications as well as "complication‐free" survival of restorations were investigated.</p> </sec> <sec id="clr12439-sec-0003" sec-type="section"> <title>Results</title> <p>The 20‐year overall cumulative implant survival was 97.2%. A few biological (3.4%) and prosthetic (10.3%) complications were reported. The "complication‐free" survival rate of restorations was 85.5%. No statistically significant differences were observed among patients' gender, age, smoking or parafunctional habits, prosthesis site and type.</p> </sec> <sec id="clr12439-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Satisfactory "complication‐free" survival rates can be achieved after 20 years for fixed restorations supported by Morse‐taper connection implants, with minimal marginal bone loss and complications.</p> </sec> </abstract>
