Abstract

<abstract abstract-type="main" id="clr12125-abs-0001"> <title>Abstract</title> <sec id="clr12125-sec-0001" sec-type="section"> <title>Objective</title> <p>The aim of this review was to test the hypothesis that 6 mm micro‐rough short Straumann<sup>®</sup> implants provide predictable survival rates and verify that most failures occurring are early failures.</p> </sec> <sec id="clr12125-sec-0002" sec-type="section"> <title>Materials and methods</title> <p>A PubMed and hand search was performed to identify studies involving micro‐rough 6‐mm‐short implants published between January 1987 and August 2011. Studies were included that (i) involve Straumann<sup>®</sup> 6 mm implants placed in the human jaws, (ii) provide data on the survival rate, (iii) mention the time of failure, and (iv) report a minimum follow‐up period of 12 months following placement. A meta‐analysis was performed on the extracted data.</p> </sec> <sec id="clr12125-sec-0003" sec-type="section"> <title>Results</title> <p>From a total of 842 publications that were screened, 12 methodologically sound articles qualified to be included for the statistical evaluation based on our inclusion criteria. A total of 690 Straumann<sup>®</sup> 6‐mm‐short implants were evaluated in the reviewed studies (Total: placed‐690, failed‐25; maxilla: placed‐266, failed‐14; mandible: placed‐364, failed‐5; follow‐up period: 1–8 years). A meta‐analysis was performed on the calculated early cumulative survival rates (CSR%). The pooled early CSR% calculated in this meta‐analysis was 93.7%, whereas the overall survival rates in the maxilla and mandible were 94.7% and 98.6% respectively. Implant failures observed were predominantly early failures (76%).</p> </sec> <sec id="clr12125-sec-0004" sec-type="section"> <title>Conclusion</title> <p>This meta‐analysis provides robust evidence that micro‐rough 6‐mm‐short dental implants are a predictable treatment option, providing favorable survival rates. The failures encountered with 6‐mm‐short implants were predominantly early and their survival in the mandible was slightly superior.</p> </sec> </abstract>
