Importantly, our analysis revealed a strong trend toward a higher rate of subsidence in the ZPD group compared to the CPS group (9.9% vs. 2.8%, p = 0.057) and multivariate logistic regression analysis, which controlled for confounding factors such as BMD, identified the implant type as an independent and significant predictor of subsidence risk (OR 5.479, 95% CI 1.269–23.666, P = 0.023).
