目的观察与分析外伤性前牙脱位牙再植术的临床治疗效果。方法本文选择了80例行外伤性前牙脱位牙再植术的患者进行研究,其中患牙100颗,手术之后的2周对再植牙的具体情况进行复查,并进行2年的随访,对2年的再植成功率进行观察。结果手术之后2周的复查,100颗(100%)再植牙全部再植成功。进行2年的随访之后,73例87颗成功再植,2年的再植成功率是87%,其中82%(71/87)脱位的时间保持在1个小时之内,年轻恒牙为66%(57/87)。4例13颗(13%)再植失败,全部属于同一时间存在多颗脱位牙,并且全部伴随着较为严重的牙槽骨折,其脱位的时间全部在1个小时之上。结论对于外伤性脱位牙进行的治疗脱位牙再植术是一种非常有效的治疗方法。处理及准备好外伤性前牙脱位患者的脱位牙以及牙槽窝,及早的对脱位牙性再植术,对其进行可靠的调节以及固定,是脱位前牙再植术的成功率有所提高的关键。
Objective To observe and analyze the clinical effect of replantation of traumatic anterior tooth dislocation. Methods 80 cases of traumatic anterior teeth dislocation replantation were selected in this study, including 100 teeth, 2 weeks after surgery on the specific conditions of replantation were reviewed and followed up for 2 years, the Two years of replantation success rate were observed. Results Two weeks after surgery, 100 replantings (100%) were replanted successfully. After 2 years of follow-up, 87 patients were successfully replanted in 73 cases. The successful rate of replantation at 2 years was 87%, of which 82% (71/87) remained within 1 hour and young permanent 66 % (57/87). Four of 13 (13%) failed to replant, all belonging to the same time multiple dislocated teeth, and all accompanied by a more serious alveolar fracture, the dislocation of time all in 1 hour above. Conclusion For the treatment of traumatic dislocation teeth dislocation dental replantation is a very effective treatment. Treatment and preparation of dislocation of teeth and alveolar fossa in patients with traumatic anterior dislocation, early dislocation of dental replantation, its reliable regulation and fixation, is the success rate of dislocation anterior dental replantation has increased key.
