塑料冠暂时固定纵折后牙的保存治疗

Preservative Therapy of the Posterior Teeth with Longitudinal Fracture by Plastic Crown Temporary Fixation

为探讨塑料冠暂时固定纵折后牙的疗效 ,采用自凝塑料冠固定纵折后牙 ,牙合面钻孔行根管治疗后铸造金属全冠修复 .结果表明 :2 8颗患牙中有 2 6颗经治疗后铸造全冠修复 ,成功2 4例 ,成功率达 85.71% .塑料冠固定纵折后牙比单纯金属丝固定效果好 ,且制作简便 .

To study the curative effect of the posterior teeth with longitudinal fracture by temporary fixation of plastic crown,the posterior teeth with longitudinal fracture was fixed with instant crown of selfcuring crylic resin, following root canal treatment and then replaced with cast crown.All of cases were followed up 1～3 years. 24 of 28 cases(85.71%) treated by this method were satisfactary.The results showed that the curative effect of the posterior teeth with longitudinal fracture fixed by the plastic crown was better than that by the tiny steel wire,and the method is simple.
