The aim of this retrospective study was to report the mid-term outcome (3 years) of standard implants with 20 to 24 mm of length in immediate function with bicortical anchorage for prosthetic rehabilitation of complete edentulous jaws with low-density bone. To this end, clinical, instrumental and 3-year outcome data of 27 patients with complete edentulous arches and low bone density treated with long implants were investigated. Follow-up examinations were performed at 10 days, 2, 4, 6 months, 1 year, 2 years, and 3 years after implant placement. Marginal bone was evaluated at baseline (before surgery) and after 1, 2, and 3 years. The survival of the prosthesis was evaluated in terms of function. A prosthesis that needed to be substituted was considered a failure. A 100% survival rate was observed. All prostheses were in function during the follow-up period. No patient was lost during the follow-up. Regarding the short implants, the average marginal bone remodelling was 0.09 ± 0.21 at the baseline time point, 0.71 ± 0.32 after 1 year and 1.48 ± 0.28 at 3-year follow-up. Similarly, a constant and significant increased average marginal bone was observed at the sites of long implants. In conclusion, the data reported improved evidence about the clinical success of using long implants (≥20 mm) in immediate function with bicortical anchorage to treat patients with low bone density and partial or complete edentulous fixed prosthetic rehabilitation. © by BIOLIFE, s.a.s.

Abstract
The aim of this retrospective study was to report the mid-term outcome (3 years) of standard implants with 20 to 24 mm of length in immediate function with bicortical anchorage for prosthetic rehabilitation of complete edentulous jaws with low-density bone. To this end, clinical, instrumental and 3-year outcome data of 27 patients with complete edentulous arches and low bone density treated with long implants were investigated. Follow-up examinations were performed at 10 days, 2, 4, 6 months, 1 year, 2 years, and 3 years after implant placement. Marginal bone was evaluated at baseline (before surgery) and after 1, 2, and 3 years. The survival of the prosthesis was evaluated in terms of function. A prosthesis that needed to be substituted was considered a failure. A 100% survival rate was observed. All prostheses were in function during the follow-up period. No patient was lost during the follow-up. Regarding the short implants, the average marginal bone remodelling was 0.09 ± 0.21 at the baseline time point, 0.71 ± 0.32 after 1 year and 1.48 ± 0.28 at 3-year follow-up. Similarly, a constant and significant increased average marginal bone was observed at the sites of long implants. In conclusion, the data reported improved evidence about the clinical success of using long implants (≥20 mm) in immediate function with bicortical anchorage to treat patients with low bone density and partial or complete edentulous fixed prosthetic rehabilitation. © by BIOLIFE, s.a.s.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
