Three-Year Outcomes of Dental Implants With a Hybrid Surface Macro-Design Placed in Patients With History of Periodontitis: A Randomised Clinical Trial. J Clin Periodontol. 2025 Jun;52(6):802-812. doi: 10.1111/jcpe.14153.

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.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/journal article1600-051Xhttps://doi.org/10.1111/jcpe.1415340277088https://onlinelibrary.wiley.com/doi/10.1111/jcpe.14153https://pubmed.ncbi.nlm.nih.gov/40277088/open access[616.314-089.843:615.46]:616.314.17-008.1Hybrid designMarginal bone lossPeriodontitisPeri‐implantitisSurface topographyOdontología (Odontología)Implantes dentalesPeriodonciaMateriales dentales3299 Otras Especialidades Médicas3213 Cirugía
