树脂嵌体与大块充填树脂、传统树脂修复离体牙Ⅱ类洞效果对比

Effect of Resin Inlay,Bulk Filling Resin and Traditional Resin in Repairing Class Ⅱ Holes in Isolated Teeth

目的 对比树脂嵌体与大块充填树脂、传统树脂修复离体牙Ⅱ类洞效果。方法 选取2023年6—12月镇江市第一人民医院收治的60例牙体缺损患者为研究对象,根据填充材料不同将患者分为树脂嵌体组、大块充填树脂组和传统树脂组,各20例。对比不同填充材料边缘裂隙宽度、边缘微渗漏深度、微渗漏等级。结果 树脂嵌体组的边缘裂隙宽度最小,其次为大块充填树脂组,最大为传统树脂组,差异有统计学意义(F=15.758,P<0.05)。边缘微渗漏深度最小为树脂嵌体组(0.95±0.08)mm,其次为大块充填树脂组的(1.12±0.10)mm,最大为传统树脂组的(1.17±0.11)mm,差异有统计学意义(F=28.00,P<0.05)。树脂嵌体组微渗漏分级低于其余两组,差异有统计学意义(P<0.05)。结论 在离体牙Ⅱ类洞修复中应用树脂嵌体,修复体边缘裂隙宽度、微渗漏深度和等级均低于大块充填树脂、传统树脂,临床效果显著。

Objective To compare the effect of resin inlay,bulk filling resin and traditional resin in repairing Class Ⅱ holes in isolated teeth.Methods A total of sixty patients with dented defects admitted to Zhenjiang First People's Hospital from June to December 2023 were selected as the research objects.According to different filling materials,the patients were divided into resin inlay group,bulk filling resin group and traditonal resin group,with 29 cases in each group.The edge crack width,edge microleakage depth and microleakage grade of different filling materials were compared.Results The edge crack width of the resin inlay group was the smallest,followed by the bulk filling resin group,and the largest was the traditonal resin group,and the difference was statistically significant(F=15.758,P<0.05).The lowest edge microleakage depth was(0.95±0.08) mm in the resin input group,followed by the bulk filling resin group(1.12±0.10) mm,and the highest was(1.17±0.11) mm in the traditional resin group,and the difference was statistically significant(F=28.00,P<0.05).The microleakage grade of resin inlays group was lower than that of the other two groups,and the difference was statistically significant(P<0.05).Conclusion Resin inlay was used in the repair of Class Ⅱ holes in isolated teeth,and the edge crack width,microleakage depth and grade of the prosthesis are lower than that of bulk filling resin and conventional resin,and the clinical effect is remarkable.
