A prospective, multi-center study assessing early loading with short implants in posterior regions. A 3-year post-loading follow-up study.

Abstract:

BACKGROUND:Few prospective studies about early loading of short implant have been available and very little evidence exists on the outcomes longer than 3 years. PURPOSE:To assess clinical and radiographic outcomes of 6 mm-short implants placed in the posterior maxilla and mandible applying an early loading protocol. MATERIALS AND METHODS:Ninety-five short implants (6 mm-short, Ø 4 mm) were placed in 45 subjects at 3 study sites, 2 or 3 implants per subject, using a one-stage surgical procedure and loaded with a screw-retained splinted fixed prosthesis 6 weeks later. Follow-up took place at 6, 12, 24, and 36 months after loading. Marginal bone level changes, implant survival, clinical variables, and adverse events were assessed. RESULTS:The survival rate for all implants placed was 95.8%. From implant loading to 3 years follow-up, mean marginal bone level changes were minimal (0.07 ± 0.49 mm) and the peri-implant soft tissue status was healthy. No major technical or biological complications occurred except for the 4 early implant losses. CONCLUSION:Three-year data indicates that the use of splinted 6 mm-short implants is a viable treatment in posterior regions with low marginal bone resorption. Early loading after 6 weeks should be taken cautiously in patients with known risk factors.
