Single Teeth and Partial Implant Rehabilitations Using Ultra-Hydrophilic Multi-Zone Anodized Surface Implants: A Retrospective Study with 1-Year Follow-Up

Background/Objectives: In the last decades, dental implant surfaces have been evolving to increase success and implant survival rates. More studies evaluating outcomes with implants with ultra-hydrophilic multi-zone anodized surfaces are necessary. The aim of this study is to evaluate the short-term outcome of implants of conical connection with anodized ultra-hydrophilic surfaces for support of single teeth and partial rehabilitations. Methods: In this retrospective study, patients received parallel-walled implants with a gradually anodized surface. The primary outcome measure was implant survival. Secondary outcome measures were marginal bone loss and mechanical and biological complications. This study included 253 conical connection implants with anodized ultra-hydrophilic surfaces, placed in 145 patients (71 males and 74 females; average age: 55.8 years). Sixty patients presented comorbidities, and 19 patients presented smoking habits. Results: Ten patients (15 implants) were lost to follow-up. Two implants failed in two patients, resulting in a cumulative survival rate of 99.2%, with 98.5% and 100% for males and females, respectively, and 99.1% and 100% for single teeth and partial rehabilitations, respectively. The average marginal bone loss was 0.52 mm at 1 year, with 0.60 mm and 0.42 mm for males and females, respectively, and 0.52 mm and 0.50 mm for single teeth and partial rehabilitations, respectively. The rate of mechanical complications was 4.8% and 3.2% at patient and implant levels, respectively. Biological complications occurred in one patient (0.7%) at one implant (0.4%). Conclusions: These results indicate that the use of implants with ultra-hydrophilic multi-zone anodized surfaces for single teeth and partial rehabilitations is viable in the short term.
