Abstract
Background/Objectives: Contemporary implant designs incorporating progressive macrogeometry and hybrid surface characteristics are intended to enhance primary stability while supporting favorable peri-implant tissue outcomes. This prospective cohort study evaluated the 2-year clinical, radiographic, prosthetic, and patient-reported outcomes of a contemporary hybrid surface tapered implant system with progressive macrogeometry. Methods: Thirty participants received 31 implants and were prospectively followed. Twenty-nine participants (30 implants) completed the 2-year follow-up evaluation. The study was prospectively registered at ClinicalTrials.gov (NCT05498662). Treatment protocols, including adjunctive grafting and loading, were selected according to predefined clinical criteria. Outcomes included implant survival and success, implant stability, peri-implant clinical parameters, marginal bone levels, prosthetic complications, and patient-reported satisfaction. Standardized radiographs were obtained longitudinally to assess marginal bone-level changes. Results: No implant failures were observed during the study period, and implant success was 96.7% at 2 years. Mean probing depths remained stable, measuring 2.91 ± 0.91 mm at 1 year and 2.86 ± 1.21 mm at 2 years. Marginal bone levels also remained stable between prosthesis delivery and the 1-year follow-up (mean change: 0.00; p > 0.05) and showed a small coronal shift between the 1- and 2-year evaluations (mean change: −0.17; p < 0.001). Prosthetic complications occurred in 16% of sites. Patient-reported satisfaction remained high throughout follow-up. Conclusions: Within the limitations of this small, single-center prospective cohort study, the evaluated implant system demonstrated acceptable clinical, radiographic, and patient-reported outcomes. Larger prospective studies are needed to confirm these findings.
