Abstract

The effect of implant size and crown-to-implant (C/I) ratio on crestal bone loss in partially edentulous patients is of interest. Fourteen patients were assigned to short, wide implant with high C/I ratio (1–1.2) or long, narrow implants with low C/I ratio (0.5–0.9). Crestal bone loss was assessed radiographically at baseline and four months post-loading using standardized imaging and blinded observers. Mean bone loss was 0.232 mm for high C/I implants and 0.459 mm for low C/I implants, with no significant difference (p = 0.133). These findings suggest that higher C/I ratios do not adversely affect short-term implant performance in the absence of mechanical overload.
