摘要: 目的

观察采用微种植体支抗对下颌第二磨牙严重近中倾斜阻生患者的正畸治疗效果,为临床正畸医生治疗该类患者提供临床依据。

方法

收集1例双侧下颌第二磨牙严重近中倾斜阻生患者的临床资料,结合文献复习,探讨治疗该类患者的正畸临床方案。

结果

患者,女性,21岁,双侧下颌第二磨牙严重近中倾斜阻生伴牙列拥挤,诊断为安氏Ⅱ类错畸形,毛氏Ⅰ1+Ⅲ1+Ⅴ类错畸形,骨性Ⅰ类错畸形。拔除15、18、28、38和48,在双侧下颌升支前缘植入微种植体,外科手术暴露双侧下颌第二磨牙后,采用微种植体与第二磨牙面舌侧扣间弹性橡皮线的牵引作用,直立下颌第二磨牙。矫治后下颌第二磨牙与对颌牙齿建立良好的咬合关系,与下颌第一磨牙建立良好的邻接关系。

结论

对下颌第二磨牙严重近中倾斜阻生的患者,微种植体能够为其正畸治疗提供支抗,简洁高效地实现良好的咬合和邻接关系。

Abstract: Objective

To observe the orthodontic treatment effect of micro-implant anchorage in the patients with severe mesioclination impaction of mandibular second molars, and to provide the clinical basis for the clinical orthodontists to treat the patients.

Methods

The clinical data of one patient with severe mesioclination impaction of bilateral mandibular second molars were collected. Combined with literature review, the orthodontic clinical scheme for the treatment of this kind of patient was discussed.

Results

One 21-year-old female patient with severe mesioclination impaction of bilateral mandibular second molars with crowded dentition was diagnosed as Angle Class Ⅱ malocclusion, Mao Ⅰ1+Ⅲ1+Ⅴ malocclusion and skeletal Class Ⅰmalocclusion.After extraction of 15, 18, 28, 38 and 48, the micro-implants were implanted in the front edge of bilateral mandibular ramus. After surgical exposure of bilateral mandibular second molars, the mandibular second molars were uprighted by using the traction of elastic rubber line between the micro-implant and the lingual buckle of surface of the second molars. After the orthodontic treatment, a good occlusal relationship was established between the mandibular second molar and the opposite teeth, and a good adjacent relationship was built up with the mandibular first molar.

Conclusion

For the patients with severe mesioclination impaction of mandibular second molars, the micro-implants can provide anchorage for the orthodontic treatment, and concisely and efficiently achieve a good occlusion and abutment relationship.

Key words: mesioclination limpaction, mandibular second molar, molar uprighting, micro-implant, crowded dentition
