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.

Eligibility Criteria

Inclusion Criteria

total edentulous patients in the lower region since at least 8 months,
sufficient amount of native bone (no augmentation procedures) in the recipient sites to allow ≥11 mm long and 4 mm wide implant installation (≥1 mm of peri-implant bone circumferentially)
systemic health
compliance with good oral hygiene
informed consent signed.

Exclusion Criteria

any disease, medication or drug that could jeopardize healing, osseointegration or treatment outcome,
untreated caries or periodontitis of the remaining teeth,
mucosal and bone tissue lesions,
severe bruxism or other parafunction habits,
unrealistic aesthetic demands,
patient taking part to another study
