Introduction: Marginal bone loss is one of the biological complications associated with dental implants, and the crown-to-implant ratio (C/I-R) is considered a potential contributing factor. This study aimed to evaluate the effect of C/I-R on marginal bone loss (MBL) in short implants placed in the posterior mandible.
Materials and Methods: In this descriptive-analytical cross-sectional study, 38 patients who received short implants in the mandible during 2022–2023 were evaluated. Marginal bone level was assessed using panoramic radiographs at implant placement and parallel periapical radiographs one year after prosthetic loading. Data were analyzed using Pearson correlation, multiple linear regression, and t-tests at a significance level of 0.05.
Results: The mean marginal bone loss in implants with a C/I-R < 1.5 was 1.1 ± 1.14 mm, and in those with a C/I-R ≥ 1.5, it was 1.04 ± 0.63 mm. No statistically significant relationship was found between the crown-to-implant ratio and marginal bone loss (P > 0.05).
Conclusion: The crown-to-implant ratio does not have a significant effect on marginal bone loss in short implants placed in the posterior mandible.
