【摘要】 目的：探究微创超薄瓷贴面技术修复前牙散在间隙的效果及美观性。方法：回顾性分析2021年6月-2023年4月笔者科室收治的前牙区散在间隙修复患者，根据治疗方案不同，将所有患者分为全瓷组(采用常规全瓷贴面修复)与超薄组(采用微创超薄瓷贴面修复)，两组各纳入30例(全瓷组患牙76颗，超薄组患牙82颗)。对比两组修复后即刻效果，修复前及修复后3个月牙周情况[菌斑指数(PLI)、龈沟出血指数(BI)、牙周探诊深度(PD)]，咬合情况(咬合力、咀嚼效率、咀嚼疼痛感)，修复后12个月的美观度(USPHS)及并发症。结果：超薄组优良率显著高于全瓷组(P<0.05)；修复后3个月，两组PLI、BI、PD均显著下降，且超薄组各指标显著低于全瓷组(均P<0.05)；修复后3个月，两组咬合力、咀嚼效率显著上升，咀嚼疼痛感显著下降，且超薄组咬合力、咀嚼效率显著高于全瓷组，咀嚼疼痛感显著低于全瓷组(均P<0.05)；修复后12个月，超薄组边缘密合度、外观、颜色评分显著优于全瓷组(P<0.05)，而两组折裂、继发龋评分差异无统计学意义(P>0.05)；超薄组并发症发生率显著低于全瓷组(P<0.05)。结论：微创超薄瓷贴面技术可改善前牙散在间隙患者牙体美学效果，恢复咀嚼功能，对牙周健康具有积极影响，且并发症少。更多还原

【Abstract】 Objective To explore the effect and aesthetics of minimally invasive ultra-thin porcelain veneer technology in the repair of anterior teeth scattered in the gap.Methods A retrospective analysis was performed on patients with repair of anterior teeth scattered in the gap from June 2021 to April 2023.According to different treatment regimens,all patients were divided into all-ceramic group (conventional all-ceramic veneer repair) and ultra-thin group (minimally invasive ultra-thin porcelain veneer repair).According to the propensity matching method,the confounding factors of baseline data were excluded,and 30 cases in each group were obtained (76 affected teeth in all-ceramic group and 82 affected teeth in ultra-thin group).The immediate effect of repair,periodontal conditions[plaque index (PLI),gingival sulcus bleeding index (BI),periodontal probing depth (PD)],occlusion conditions (occlusal force,masticatory efficiency,masticatory pain) before repair and after 3 months of repair and aesthetic effect (USPHS) and complications after 12 months of repair were compared between groups.Results The excellent and good rate in ultra-thin group was significantly higher than that of the all-ceramic group (P<0.05).After 3 months of repair,the PLI,BI and PD of the two groups were decreased significantly,and the indicators in ultra-thin group were significantly lower than those in all-ceramic group (all P<0.05).The occlusal force and masticatory efficiency in both groups were increased significantly after 3 months of repair while the masticatory pain was decreased significantly,and the occlusal force and masticatory efficiency in ultra-thin group were significantly higher while the masticatory pain was significantly lower compared to all-ceramic group (all P<0.05).After 12 months of repair,the scores of edge density,appearance and color in ultra-thin group were significantly better than those in all-ceramic group (P<0.05),but there were no significant differences in the scores of fracture and secondary caries between groups(P>0.05).The incidence of complications in ultra-thin group was significantly lower than that in all-ceramic group (P<0.05).Conclusion Minimally invasive ultra-thin porcelain veneer technology can improve the dental aesthetics and restore the masticatory function in patients with anterior teeth scattered in the gap,and it has a positive impact on periodontal health and has few complications.更多还原
