摘要
目的 观察锥形束CT(CBCT)测量下颌低平牙槽嵴修复前牙槽骨高度、皮质骨厚度及密度与修复效果的相关性。方法选取2022年1月至2023年10月下颌低平牙槽嵴患者146例,均行全口义齿修复,随访6个月,根据义齿固位效果分为修复良好组(121例)与修复不良组(25例)。比较两组基线资料、修复前CBCT测量的牙槽骨高度、皮质骨厚度、皮质骨密度,分析修复前牙槽骨高度、皮质骨厚度、皮质骨密度与牙槽嵴分级的关系及与修复效果的相关性,并评价修复前牙槽骨高度、皮质骨厚度、皮质骨密度对修复效果的预测价值。结果修复不良组牙槽嵴分级Ⅳ级比例高于修复良好组(P<0.05);修复不良组修复前牙槽骨高度、皮质骨厚度、皮质骨密度低于修复良好组(P<0.05);牙槽嵴Ⅳ级患者修复前牙槽骨高度、皮质骨厚度、皮质骨密度低于修复良好组(P<0.05);修复前牙槽骨高度、皮质骨厚度、皮质骨密度与牙槽嵴分级呈负相关(P<0.05);ROC曲线分析显示,修复前牙槽骨高度、皮质骨厚度、皮质骨密度及联合预测下颌低平牙槽嵴修复效果的AUC为0.815、0.769、0.820、0.913;以ROC曲线获取的最佳截断值分为低值与高值,危险度分析,修复前牙槽骨高度、皮质骨厚度、皮质骨密度低值的下颌低平牙槽嵴患者修复不良风险是高值患者的6.884倍、6.160倍、6.585倍(P<0.05)。结论 CBCT测量下颌低平牙槽嵴修复前牙槽骨高度、皮质骨厚度、皮质骨密度与牙槽嵴分级、修复效果显著相关,对修复效果具有较高的预测价值,可协助临床进行早期预测,为制定可靠的修复方案提供客观依据。
Objective To observe the correlation between the alveolar bone height,cortical bone thickness and density measured by conical beam CT(CBCT) before mandibular alveolar ridge restoration and the restoration effect.Methods A total of 146 patients with low flat mandibular alveolar ridge were selected from January 2022 to October 2023,all of whom underwent full denture restoration.They were followed up for 6 months,and were divided into good repair group(121 cases) and poor repair group(25 cases) according to the denture retention effect.The baseline data,alveolar bone height,cortical bone thickness and cortical bone mineral density measured by CBCT before restoration were compared between the two groups.The relationship between alveolar bone height,cortical bone thickness and cortical bone mineral density and alveolar ridge grade and the correlation with the restoration effect were analyzed,and the predictive value of the restoration effect was evaluated.Results The proportion of alveolar ridge grade IV in poor repair group was higher than that in good repair group(P<0.05).The anterior alveolar bone height,cortical bone thickness and cortical bone density in poor repair group were lower than those in good repair group(P<0.05).The alveolar bone height,cortical bone thickness and cortical bone density of patients with grade IV alveolar ridge before restoration were lower than those in good restoration group(P<0.05).Alveolar bone height,cortical bone thickness and cortical bone density were negatively correlated with alveolar ridge grade before restoration(P<0.05).ROC cu rve analysis showed that the AUC of anterior alveola r bone height,co rtical bone thickness,cortical bone density and the com bined prediction effect of mandibula r alveolar ridge restoration were 0.815,0.769,0.820 and 0.913.The best truncation value obtained by ROC cu rve was divided into low value and high value.Risk analysis showed that the risk of poor repair in patients with low mandibular alveolar ridge with low value of anterior alveolar bone hei
