This study aimed to evaluate the use of orthodontic mini-implants for the intrusion of supraerupted maxillary molars.
Nine patients were treated using buttons bonded on dental surfaces and mini-implants inserted on the buccal and palatal sides. The intrusion was evaluated by comparing radiographs obtained at the start of treatment and at the end of intrusion. The t test was used to compare the teeth positions.
There was statistically significant intrusion using this method (mean: 2.4 mm; minimum: 1.2 mm; and maximum: 4.5 mm; P = .00).
The direct use of orthodontic mini-implants was effective for the intrusion of maxillary molars.
本研究旨在评估正畸微型种植体在上颌磨牙伸长矫治中的应用。
对9例患者进行治疗，在牙面粘结纽扣并在颊侧和腭侧植入微型种植体。通过比较治疗开始时和伸长矫治结束时拍摄的X线片来评估伸长情况。采用t检验比较牙齿位置。
采用该方法实现了具有统计学意义的伸长（平均值：2.4mm；最小值：1.2mm；最大值：4.5mm；P = .00）。
直接使用正畸微型种植体对上颌磨牙伸长矫治有效。
