Long-Term Clinical and Radiographic Analysis of Platform Matching and Platform Switching Implants in the Esthetic Zone: A Retrospective Cohort Study

Background: The aims of this study are to retrospectively compare the clinical, radiographic and esthetic outcomes platform switching (PS) matching (PM) dental implants in anterior maxilla after ≥ 10 years functional loading. Methods: Marginal bone loss (MBL) levels were recorded; furthermore, peri-implant clinical parameters (PPD, BOP, PI) collected Pink White Esthetic scores (PES/WES) used evaluate outcomes. Wilcoxon signed rank tests performed among two groups, with a p-value < 0.05. Results: A final sample 58 patients was enrolled (PM = 29; PS 29). showed lower MBL (1.02 ± 0.81 mm vs. 1.67 0.99 mm, p 0.028) PPD values (3.69 1.1 5.16 1.09 0.001) compared PM implants. Mean PES higher group (8.46 0.69 7.89 0.78, 0.005), while there no differences for WES (7.82 7.71 0.85, > 0.05) diseases’ prevalence (p 0.05). Conclusions: After years, statistically significant
