目的比较分析两种术式导萌对上颌埋伏阻生中切牙牙周组织影响。方法 40例上颌埋伏阻生中切牙,分别采用开窗术和根向复位瓣术联合正畸牵引移入牙弓正常位置。结果 12例采用开窗术导萌入牙弓位置后,1例松动度1度,1例出现1~2 mm唇侧牙龈退缩,2例有牙龈炎症和(或)牙龈增生堆积症状,而28例采用根向复位瓣术中,有2例牙齿1度松动,2例唇侧牙龈退缩现象,5例不同牙龈炎症状,40例牙牙髓活力检测均无异常。结论两种术式导萌上颌埋伏中切牙,对牙周组织影响无统计学意义(P>0.05)。

Methods Forty cases of maxillary impacted incisors were treated with fenestration and root reduction and orthodontic traction respectively. Results One case had loosening degree of 1 degree and one case had 1 ~ 2 mm gingival recession on the labial margin. Two cases had gingival inflammation and / or gingival hyperplasia and accumulation symptoms. In the case of root reduction, there was no abnormality in 2 cases with 1 degree of loosening, 2 cases of labial gingival recession, 5 cases of different gingivitis symptoms and 40 cases of dental pulp vitality.
