A retrospective case report series of clinical outcomes with moderately rough, wide-diameter 8-mm implants in the posterior maxilla

Int J Periodontics Restorative Dent. 2013 Jul-Aug;33(4):e95-100. doi: 10.11607/prd.1440.


Patients with insufficient residual alveolar bone height are often treated using short implants. Historically, short implants are associated with higher failure rates. However, recent research has shown short implants with modified surfaces to have success rates similar to those of longer implants. This retrospective report aimed to evaluate clinical outcomes of 8-mm-wide diameter, moderately rough threaded implants in the posterior maxilla. From June 2008 through May 2010, 16 patients were identified who had been treated with short implants. The mean age of the patients was 50.4 years, the mean primary stability of the implants was 66 ISQ, the mean secondary stability was 75.6, and the mean loading time was 16.2 months. There were no failed implants. The mean marginal bone loss at final follow-up was 0.04 mm. This study exhibited excellent short-term clinical outcomes.
