摘要
目的:探讨种植牙修复中保留拔牙位点对患者修复后美观度及中远期骨缺失的影响。方法:选取鹰潭市人民医院2021年1月—2022年3月收治的种植牙修复患者81例为研究对象。采用随机数字表法将其分为对照组(40例)和观察组(41例)。两组均采用微创拔牙,对照组采用常规种植牙修复,观察组采用保留拔牙位点的种植牙修复。比较两组拔牙前、拔牙6个月及12个月后牙槽骨骨密度、骨高度、骨宽度变化,比较两组美观度、满意度评分及种植成功率情况。结果:拔牙前,两组牙槽骨骨密度、骨高度、骨宽度组间比较,差异均无统计学意义(P>0.05);拔牙6、12个月后,两组牙槽骨骨密度、骨高度均低于拔牙前,骨宽度均小于拔牙前(P<0.05);但观察组拔牙6、12个月后牙槽骨骨密度、骨高度均高于对照组,骨宽度均大于对照组,差异均有统计学意义(P<0.05);两组拔牙前、拔牙6个月及12个月后牙槽骨骨密度、骨高度、骨宽度比较存在交互作用,差异均有统计学意义(P<0.001);观察组美观度与满意度评分均高于对照组,差异均有统计学意义(P<0.001);两组种植成功率比较,差异无统计学意义(P>0.05)。结论:种植牙修复中拔牙位点保留技术可减少患者骨吸收,保护牙槽骨骨密度、骨高度、骨宽度,提升拔牙修复后的美观度和满意度,值得临床推广和应用。
Objective:To investigate the effect of retaining the extraction site in dental implant restoration on the aesthetic appearance and mid to long-term bone loss of patients after restoration.Method:A total of 81 patients with dental implant restoration admitted to Yingtan People's Hospital from January 2021 to March 2022 were selected as the research subjects.They were divided into the control group(40 cases)and the observation group(41 cases)using random number method.Both groups of patients were treated with minimally invasive tooth extraction,the control group received conventional dental implant restoration,the observation group received dental implant restoration with retaining the extraction site.The changes in alveolar bone density,bone height,and bone width between two groups of patients before tooth extraction,6 and 12 months after tooth extraction were compared.The aesthetic appearance,satisfaction score,and implant success rate between the two groups were compared.Result:Before tooth extraction,there were no statistically significant differences in alveolar bone density,bone height,and bone width between the two groups of patients(P>0.05);after 6 and 12 months of tooth extraction,the alveolar bone density,bone height,and bone width of both groups of patients were lower than those before tooth extraction(P<0.05);however,after 6 and 12 months of tooth extraction,the bone density and height of the alveolar bone in the observation group were higher than those in the control group,and the bone width were greater than those in the control group,the differences were statistically significant(P<0.05).There were interactive effect between the two groups of patients in terms of alveolar bone density,bone height,and bone width before tooth extraction,6 months after tooth extraction,and 12 months after tooth extraction,the differences were statistically significant(P<0.001).The aesthetic appearance and satisfaction scores of the observation group were higher than those of the control group,the differences were statistically significant(P<0.001).There was no statistically significant difference in the success rate of implantation between the two groups(P>0.05).Conclusion:The technique of preserving the extraction site in dental implant restoration can reduce patient bone resorption,protect alveolar bone density,bone height,and bone width,and improve the aesthetic appearance and satisfaction after tooth extraction restoration,it is worthy of clinical promotion and application.
