Abstract

Introduction: The use of in vitro implants can repair severe resorption. This sometimes requires the use of prostheses in the most extreme cases, when the proportion of crown implants is not ideal, to reach 2:1 or 3:1. Materials and methods: clinical analysis was carried out on implants with a residual of 5.5mm or less and more than 6 months. Chi square test was used for categorical variables and student t–test was used for continuous variables. Then, a linear fitting regression model is established. Results: Six patients received in vitro implantation. 21.2% of the patients in the study were male and 78.8% were female, with an average age of 57 years. The average crown planting ratio was 3.19 (+/–0.24). The average bone loss of the implant was 0.86mm (+/–0.33) in the near median position and 0.83mm (+/–0.47) in the anterior position. There was no statistically significant difference in the functional proportion of proximal and distal bone loss (P=0.224). Conclusion: According to the data provided in this study, even if the crown implant.
