Brief summary
The study involved 28 edentulous patients (20 female/8 males; average age of 67.75± 8.627 years) rehabilitated with 33 prostheses (17 all-on-4/16 all-on-6) supported by 164 implants.
Detailed description
Clinical and radiographic outcomes were implants survival, prostheses success/survival, implant marginal bone loss, incidence of biological and prosthetic complications.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Implant marginal bone loss (MBL) | from the functional loading time with the provisional prosthesis (baseline) T0 to the end of the follow-up, assessed up to 10 years and measured in millimeters on periapical radiographs taken every year using the parallel long-cone technique. | difference in marginal bone level from the functional loading time with the provisional prosthesis (baseline) to the end of the follow-up measured in millimeters/years on periapical radiographs. Periapical radiographs of each implant were taken every year using the parallel long-cone technique and a standardized film holder (Rinn Centratore XCP Evolution 2003, Dentsply, Rome, Italy). |
| Prosthetic complications | Every 6 months from the functional loading time with the provisional prosthesis (baseline) to the end of the follow-up, assessed up to 10 years. | included detachment/incisal and occlusal wear/fracture/chipping/replacing of denture teeth, fracture of implant, prosthesis or framework, loosening/fracture of abutment or occlusal screw, loosening/fracture of the prosthetic screw |
| Biologic complications | Every 6 months from the functional loading time with the provisional prosthesis (baseline) to the end of the follow-up, assessed up to 10 years. | inflammation / infection under fixed prosthesis, soft tissue hypertrophy / hyperplasia, soft tissue recession / dehiscence, peri-implant mucositis, peri-implantitis. Modified plaque index (mPI), modified gingival index (mGI), bleeding on probing (BoP), and probing depth (PD). mPI, mGI, BoP, and PD measurements were performed at 6 aspects per implant. mPI was scored as: 0 = no detection of plaque; 1 = plaque only recognized by running a probe across the smooth marginal surface of the implant; 2 = plaque can be seen by the naked eye; 3 = abundance of soft matter. mGI was scored as: 0 = no bleeding when a periodontal probe is passed along the mucosal margin adjacent to the implant; 1 = isolated bleeding spots visible; 2 = blood forms a confluent red line on mucosal margin; 3 = heavy or profuse bleeding. BoP was scored as 0 = absence; 1 = presence; PD was measured in mm. |
