Primary outcomePrimary: Marginal Bone Level (MBL) Change — 0.30; 0.40 mm
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.
