Brief Summary:
The aim of this study is to clinically and radiographically compare the performance of short (6 mm-long) versus long (≥11 mm-long) dental implants placed in the interforaminal region of fully edentulous mandibles, supporting a screw-retained full-arch cantilever bridge.
Detailed Description:
The use of short dental implants provides undeniable benefits in sites where the reduced available volume would otherwise need bone augmentation procedures and their use has greatly expanded in the recent years. However, well designed clinical trials which provide a sound evidence of their performance and reliability are still lacking to date.
In this post-market, multi-center, open, parallel-group, randomized, controlled clinical trial the investigators aim to to clinically and radiographically compare the performance of short (6 mm-long) versus long (≥11 mm-long) dental implants supporting a mandibular screw-retained full-arch cantilever bridge.
Five 4mm-wide/6mm-long (test) or 4mm-wide/≥11mm-long (control) titanium dental implants (Osseospeed™, ASTRA TECH Implant System™, Dentsply Sirona) are placed in the interforaminal region of fully edentulous mandibles, in non-regenerated sites, with at least 1 mm of peri-implant bone circumferentially.
All products are CE (European Conformity) marked and used within their intended use.
Two-Stage surgery is performed, implants are positioned in healed bone and exposed after 3 months to be connected with the prosthesis.
This is a medium-term follow-up study including evaluations also at 1 and 3 years from the baseline.
Three italian centers participate: Naples (University of Campania "Luigi Vanvitelli"), Naples (AORN "A. Cardarelli"), Catania (Private Office).
The study protocol has been approved by the Institutional Review Board of the University of Campania "Luigi Vanvitelli".
