摘要
目的观察改良C型粘结固定桥修复下颌单个后牙缺失伴桥基牙倾斜的患者的临床效果.方法选择口腔门诊下颌单个后牙缺失并伴远端基牙向近中或舌侧倾斜的32例患者,采用改良C型粘结桥修复,修复体粘结后即刻、半年、1 a和2 a观察,对修复体边缘适合性、基牙菌斑指数、X线片检查和患者主观感受等方面进行评价.结果修复后半年内复查,未有一例失败,基牙菌斑指数与对照牙相比,差异无统计学意义(P>0.05);0.5～2 a定期复查有4例舌侧属翼板松脱,但患者自觉咀嚼功能良好,X线片显示基牙牙周膜间隙无异常,基牙菌斑指数与对照牙相比,差异有统计学意义(P<0.05).结论改良C型粘结固定桥修复下颌单个后牙缺失,短期临床修复效果较好,树脂粘接技术也能满足临床修复的要求,但修复后牙周的维护是很有必要的.
Objective To observe the clinical result of patients with single posterior tooth and abutment tooth bevel repaired by improved C-type retainer adhesion fixed bridge.Methods 32 patients with loss of mandibule single posterior tooth and abutment tooth bevel buccal or lingual direction were selected using C-type retainer adhesion fixed bridge to restore.We observed the bonder compatibility,abutment dental plaque index, radiography and subjective perception of patients after bond instantly,half a year,1year and 2 years after treatment.Results Patients were reviewed in half a year after treatment,and there was no failure.Compared with control teeth,abutment dental plaque index didn＇t show statistically significant difference（P0.05）.4 cases occurred lingual wing loosening after recheck in 0.5-2 years,but patients felt good masticatory function. Radiography displayed normal periodontal membrane space,abutment dental plaque achieved statistically significant difference（P0.05）.Conclusion Improved C-type retainer adhesion fixed bridge has better repair effect in short-term,the technique of resin splice can also satisfy the request of repair,and protecting periodontal tissue is necessary following repair.
