目的评价应用微螺钉种植体压低上前牙以改善露龈笑的临床效果。方法选择11例露龈笑伴前牙深覆患者,其中男性1例,女性10例,年龄18.6~24.3岁,平均21.2岁,在上颌双侧侧切牙与尖牙间唇侧植入微螺钉种植体,配合全口固定矫治器,以种植体支抗弹性牵引的方式压低上前牙,力量约为每牙30~50 g,压低时间平均约为7个月,治疗前后拍摄全口曲面断层片进行测量对比,观察前牙的位置变化和露龈笑改善的程度。结果 11例患者治疗后上颌前牙平均压低3.8 mm,深覆得到有效的纠正,露龈笑明显改善。结论利用微螺钉种植体支抗能有效地压低上前牙改善露龈笑,实现了前牙的绝对压入,避免了使用传统支抗措施压低前牙时的副作用,是一种纠正深覆改善微笑曲线的较好方法,值得在临床上推广。
Objective To evaluate the clinical effect of using micro-screw implants to lower the anterior teeth to improve the gingiva. Methods Eleven patients with deep gingival sulcus who had gingival recession were selected, including 1 males and 10 females, aged from 18.6 to 24.3 years old (average 21.2 years old). Micro-screws were implanted into the lateral maxillary lateral incisors and canines Body, with a full mouth fixed appliance, implants with implant elastic traction way to lower the upper anterior teeth, the strength of about 30 ~ 50g per tooth, the average time to suppress about 7 months before and after the treatment of full face curved surface film Measurements were made to compare the changes in the position of the anterior teeth and the degree of improvement of the gums. Results Eleven patients underwent an average reduction of 3.8 mm in anterior maxillary anterior teeth, which was effectively corrected in deep lashes and the gingival larynx was significantly improved. Conclusion The use of micro-screw implant support can effectively reduce the anterior teeth to improve the gingival laryngeal, to achieve the absolute pressure of the anterior teeth to avoid the use of traditional support measures to reduce the side effects of anterior teeth is a correction to improve the coverage A better way to smile curves is worth promoting in the clinic.
