Primary outcomePrimary: Marginal Bone Loss — 1.17; 0.83; 1.28; 0.96 millimeters
Summary
A prospective randomized controlled clinical trial will be conducted. Study groups will be assigned as described above. The patients will be randomly divided into two groups in order to study the influence of prosthetic screw abutment in marginal bone loss (MBL) around Bone Level Tapered implants (BLT® Roxolid® SLActive® guided implants, Straumann Dental Implant System, Institut Straumann AG, Basel, Switzerland).
