Three-Year Outcomes of Dental Implants With a Hybrid Surface Macro-Design Placed in Patients With History of Periodontitis: A Randomised Clinical Trial
Aim: This randomised controlled trial (RCT) with a 3-year follow-up was aimed at assessing the clinical and radiographic outcomes of implants with either a hybrid or moderately rough macro-surface design placed in patients with a history of periodontitis.

| Sumario: | Aim: This randomised controlled trial (RCT) with a 3-year follow-up was aimed at assessing the clinical and radiographic outcomes of implants with either a hybrid or moderately rough macro-surface design placed in patients with a history of periodontitis. Material and methods: Forty periodontitis subjects with a stable periodontal condition were included and randomly assigned to receive either a hybrid implant with a machined-collar surface (HS) or a conventional implant with a moderately rough-collar surface up to the shoulder (RS). Radiographic, clinical, microbiological and patient-related outcome measurements (PROMs) were assessed at baseline (implant loading) and 3, 6, 12, 24 and 36 months post-loading. Results: Thirty-six patients (17 and 19, in the test and control groups, respectively) completed the three-year follow-up. At this visit, mean marginal bone level (MBL) changes were -0.08 (SD 0.2) and 0.02 (SD 0.28) mm for the test and control groups, respectively, with only three patients exhibiting MBLs exceeding 1 mm and only one implant with a peri-implantitis diagnosis. Patients in both groups showed a high degree of satisfaction, and implants in both groups harboured a similar proportion and counts of measured periodontal pathogens. No significant differences were observed between the two groups regarding any of the radiographic, clinical or microbiological variables. Conclusions: At the three-year follow-up, both implant groups demonstrated high peri-implant bone stability, as well as a low incidence of peri-implant diseases. |
