植入位点骨条件对动态导航技术下种植精度的影响
Influence of bone condition at implant sites on implant accuracy by dynamic navigation technology
摘要
Abstract
Objective:To evaluate the influence of bone condition at implant sites on the accuracy of implant place-ment with dynamic navigation technology.Methods:A retrospective analysis was conducted on patients with dental arch de-fects in the posterior mandibular region who underwent dynamic navigation implant surgery from 2022 to 2023.A total of 30 implant from 26 patients were studied.The bone density at the implant site,as well as crestal cortical bone thickness,bucco-lingual cortical and cancellous bone thickness at 3,6,and 9 mm below the crestal bone were measured.The ratio of cortical bone thickness to cancellous bone thickness at different depths was calculated.Pearson correlation analysis and multiple line-ar regression analysis were performed to assess the correlation between these bone conditions and implant deviation data.Re-sults:The bone density was significantly negatively correlated with the implant angle deviation(r=-0.471,P＜0.01),indica-ting a significant causal relationship(b=-0.005,P＜0.01).The implant angle deviation was also negatively correlated with crestal cortical bone thickness(r=-0.400,P＜0.05),as well as with buccolingual cortical bone thickness at 3 mm below the crestal bone(r=-0.372,P＜0.05),and the ratio of cortical bone thickness to cancellous bone thickness at 3 mm below the crestal bone(r=-0.362,P＜0.05).Conclusion:Higher bone density and greater cortical bone thickness in the implant area are associated with smaller deviations in implantation angles by dynamic navigation technology.关键词
