玻璃纤维桩联合复合树脂修复牙颈部缺损的美学效果及临床疗效(1)
[摘要]目的:评价纤维桩联合复合树脂修复前磨牙重度楔状缺损的美学效果和临床疗效。方法:选择96例患者的128颗穿髓型楔状缺损的前磨牙,64颗采用玻璃纤维桩联合复合树脂修复,64颗采用采用简单树脂核充填法修复。统计修复后即时及1年后的美学效果,及修复后1年的临床疗效。结果:在美学效果评价方面,两组的美学效果在修复后即时比较,差异无统计学意义(P>0.05);而修复后1年则前者优于后者,差异有统计学意义(P<0.05)。在临床疗效上玻璃纤维桩联合复合树脂修复明显优于简单树脂核修复,差异有统计学意义(P<0.01)。结论:玻璃纤维桩联合复合树脂修复穿髓型楔状缺损患牙,具有良好的美学效果和临床疗效。

Abstract: Objective To evaluate the aesthetics and clinical effect of severe wedge-shaped defect of premolar restored with fiber post-core combined with composite resin. Methods 128 teeth in 96 cases with severe wedge-shaped defects were randomly divided into two groups.64 teeth were restored with fiber post-core combined with light-cured composite resin and the other 64 teeth restored by only composite resin.Evaluation of aesthetic effect was made immediately and 1 year later respectively.Evaluation of clinical effect was made after restoration for 1 year. Results Aesthetic effects were no significant difference between the two groups on immediate postoperative(P>0.05), and 1 year later the former was better than the latter(P<0.05).The clinical efficacy on the glass-fiber post restored was significantly better than the simple composite resin core repaired(P<0.01).Conclusion The aesthetics and clinical effect of severe wedge-shaped defect of premolar restored by fiber post-core combined with composite resin is preferable.

前磨牙的重度楔状缺损通常伴有牙髓病、根尖周病的临床症状[1],经过根管治疗后,可以采用玻璃纤维桩联合复合树脂修复,也可以通过复合树脂核简单充填修复。本研究分别采用这两种方法,修复后即时及1年后随访,评价修复后的美学效果和临床疗效,以期指导临床。
1 资料和方法
1.1 一般资料
2013年1月-2014年3月就诊于天津大学医院口腔科的96例患者的128颗重度楔状缺损的前磨牙,患者年龄37~75岁,平均59岁。128颗前磨牙中,上颌牙53颗,下颌牙75颗。按患者知情同意、自愿原则,将受试者分为两组,第1组48例(64颗)采用玻璃纤维桩联合复合树脂修复,第2组48例(64颗)采用树脂核充填法修复。
1.2 材料与设备
ParaBond?粘结系统和ParaCore?双固化树脂(Coltene公司,美国);TENAX?多型号玻璃纤维桩及匹配扩孔钻(康特公司,瑞士);3M ESPE Filtek Z350通用型光固化复合树脂(3M公司,美国);Adper Prompt自酸蚀粘结剂(3M公司,美国)。
1.3 治疗方法
全部患牙经过完善的根管治疗后,无主观及临床症状,无根尖病变或根尖病变已明显好转。两组分别采用玻璃纤维桩联合复合树脂充填及树脂核充填法修复。修复后牙体最外层使用3M ESPE Filtek Z350通用型光固化复合树脂美学修复。
1.4 效果评价
修复术后1年定期复诊。①成功:临床观察无自觉症状,能正常行使咀嚼功能,充填物保持正常形态,与洞壁密合,无缝隙染色或继发龋,叩诊无不适,X线片显示未发生牙折,根尖周正常或病变无进展,牙周正常;②失败:修复后咀嚼功能不良,有咬合痛或叩痛,修复体松动、脱落,桩折,根折,牙龈红肿明显或牙周袋形成,有任何一项均为失败。修复后即时美学评价及1年后复查。美学效果满意度:①满意:患者对修复后的患牙外形、颜色、光泽、通透度等满意,修复体无异物感;②不满意:对修复后的患牙外形、颜色、光泽、通透度等有任一不满意者[2]。
1.5 统计学方法:使用SPSS 18.0统计学软件进行数据处理,成功率的比较采用χ2检验,检验水准α=0.05。 (侯曦晨)
