摘　　要：目的探究个别托盘不同预留空间厚度与牙槽嵴低平无牙颌义齿修复的关系。方法选择2020年3月至2023年3月期间于我院就诊的75例牙槽嵴低平无牙颌患者,采用随机数字表法将患者分为A组(n=25)、B组(n=25)和C组(n=25),3组分别按无预留空间(0 mm),预留空间(1.5 mm)和(2 mm)制作个别托盘并行全口义齿修复。对比3组患者的一般资料、修复有效率、VAS评分、TMD及PES评分,并分析3组患者修复后的满意程度评分。采用广义估计方程模型评价3组患者各项指标的改善情况。结果3组在终印与组织面的偏差值、复诊次数以及压痛位点之间存在显著差异,B组<C组<A组(P<0.05)。B组患者的总有效率高于A组和C组(P<0.05)。术后3个月,3组患者的VAS评分无明显差异,B组患者的TMD评分显著低于A组和C组,PES评分显著高于A组和C组(P<0.05)。比较3组患者对固位效果、稳定性、咀嚼功能、舒适度的满意度,B组患者的满意度明显高于A组和C组(P<0.05)。经广义估计方程分析可见:B组在TMD评分、PES评分、固位效果、稳定性、咀嚼功能、舒适度方面的改善情况优于A组和C组,C组在各方面的改善情况优于A组。结论个别托盘预留空间为1.5 mm时制作终义齿组织面与粘膜形态适合性较好、复诊次数和压痛位点较少、修复效果较好、患者的满意度较高。Objective Exploring the relationship between different reserved space thicknesses of individual trays and the restoration of edentulous dentures with a low and flat alveolar ridge.Methods 75 edentulous patients with low and flat alveolar ridge who were treated in the hospital from March 2020 to March 2023 were selected and randomly divided into Group A(n=25),Group B(n=25),and Group C(n=25)using a random number table method.The three groups were treated by fabricating individual trays and restoring dentures with no reserved space(0 mm),reserved space(1.5 mm)and(2 mm),respectively.Compare the general information,repair efficiency,VAS score,TMD,and PES scores of the three groups of patients,and analyze the satisfaction scores of the three groups of patients after restoration.Use a generalized estimation equation model to evaluate the improvement of various indicators in three groups of patients.Results There were significant differences among the three groups in the deviation values of the final impression from tissue surface,number of follow-up visits,and tenderness sites,with Group B<Group C<Group A(P<0.05).The total effective rate of Group B was higher than that of Group A and Group C(P<0.05).Three months after surgery,there was no significant difference in VAS scores among the three groups of patients,and TMD scores of Group B were significantly lower than those of Group A and Group C,while PES scores were significantly higher than those of Group A and Group C(P<0.05).Comparing the satisfaction of three groups of patients with regard to retention effect,stability,chewing function,and comfort,the satisfaction of Group B was significantly higher than that of Group A and Group C(P<0.05).By generalized estimation equation analysis,it was shown that Group B had superior improvement in TMD score,PES score,retention effect,stability,chewing function,and comfort than Group A and Group C,while Group C had better improvement in all aspects than Group A.Conclusion Individual trays with reserved space(1.5 mm)produced a bett
