J Endod:无创拔牙系统对颈环外吸收牙齿的意向再植应用

2019-09-07 lishiting MedSci原创

颈环外吸收(ECR)通常会导致牙齿无法修复,特别是范围较深已达到牙本质硬组织层面。有时,意向再植成为挽救牙齿的最后一种方法,但由于牙周膜细胞损伤或冠折的风险较高而使常规的外科拔除手术受到一定的限制。这篇病例报告描述的是一例采用轴向无创拔牙系统对其他方法无法挽救的存在ECR的上颌中切牙施以意向再植技术的病例汇报。

颈环外吸收(ECR)通常会导致牙齿无法修复,特别是范围较深已达到牙本质硬组织层面。有时,意向再植成为挽救牙齿的最后一种方法,但由于牙周膜细胞损伤或冠折的风险较高而使常规的外科拔除手术受到一定的限制。这篇病例报告描述的是一例采用轴向无创拔牙系统对其他方法无法挽救的存在ECR的上颌中切牙施以意向再植技术的病例汇报。

患者为一位37岁无任何病史且无任何症状的男性。治疗方案包括无创拔牙,随后去除肉芽组织、口外根管治疗和粘接修复外吸收损伤。在口外操作期间,最大限度的避免牙根表面干燥,施以牙科粘接材料或在治疗过程中对牙周膜损伤施以热诱导。再植2年半,临床和X线影像检测显示,牙齿正常愈合并且没有任何症状,与术前相比骨水平存在轻微的减少,无牙根吸收或关节强直的指征。

结论:这篇病例的成功疗效表明,采用无创拔牙系统的意向再植理念能够挽救颈环外吸收牙齿并且可以避免拔牙过程中折断的高风险。
