【摘要】 目的：探究In-ceram全瓷嵌体在恒磨牙Ⅱ类洞修复中的应用及对美观度、预后的影响。方法：回顾性分析2021年1月-2022年12月笔者医院收治的200例(200颗患牙)恒磨牙Ⅱ类洞患者的临床资料，根据修复材料不同分为全瓷嵌体组102例(102颗患牙)和复合树脂组98例(98颗患牙)，全瓷嵌体组给予In-ceram全瓷嵌体修复，复合树脂组给予复合树脂嵌体修复。比较两组患者修复效果、微渗漏，修复前和修复后3个月的美学效果[改良美国公共卫生署直接临床评价系统(USPHS)]及预后[口腔健康影响程度量表(OHIP-5)]。结果：修复后3个月，全瓷嵌体组修复成功率高于复合树脂组，微渗漏轻于复合树脂组(均P<0.05)；两组USPHS评分均显著升高，全瓷嵌体组高于复合树脂组(均P<0.05)；OHIP-5评分显著降低，全瓷嵌体组低于复合树脂组(P<0.05)。结论：In-ceram全瓷嵌体在恒磨牙Ⅱ类洞修复中效果更显著，可减轻微渗漏，提高牙体美观度，改善预后效果。更多还原

【Abstract】 Objective To explore the application of In-ceram all-ceramic inlay and composite resin inlay in the repair of permanent molar Class II cavity defects and the influence on aesthetic degree and prognosis.Methods The clinical data of 200 patients (200 affected teeth) with permanent molar Class Ⅱ cavity defects admitted to the hospital from January 2021 to December 2022 were retrospectively analyzed.According to different repair materials,the patients were divided into all-ceramic inlay group (102 affected teeth) and composite resin group (98 affected teeth).The all-ceramic inlay group was given In-ceram all-ceramic inlay repair,and the composite resin group was given composite resin inlay repair.The repair effect,microleakage,and aesthetic effect[United States Public Health Service direct repair evaluation criteria (USPHS)]and prognosis[Oral Health Impact Profile-5 (OHIP-5)]before repair and after 3 months of repair were compared between the two groups.Results After 3 months of repair,the success rate of repair in all-ceramic inlay group was higher than that in composite resin group,and the microleakage was milder than that in composite resin group (all P<0.05).The USPHS scores were significantly enhanced,and the scores in all-ceramic inlay group were higher than those in composite resin groups (all P<0.05).The score of OHIP-5 was significantly reduced,and the score in all-porcelain inlay group was lower compared with that in composite resin group (P<0.05).Conclusion In-ceram all-ceramic inlay has a significant repair effect,and it can relieve the microleakage,enhance the dental aesthetic degree and improve the prognosis effect.更多还原
