This work aimed to evaluate an alternative form of maxillary expansion anchored with mini-implants. A patient 12 years, class III in permanent canine teeth, with multiple agenesis of upper posterior teeth was treated with the aid of four mini-implants in the palate and Haas modified type appliance. During the period of expansion, an interincisal diastema was observed as the first clinical sign of disjunction of the sutures. After correction of cross bite, the expansion of the palate was confirmed by upper occlusal radiographs. Thus, the evaluations showed that the technique was effective and that new scientific studies should be conducted to further develop this subject.

这项研究旨在评估一种使用微型种植体锚固的上颌扩弓替代方法。一名12岁的恒牙列III类错颌患者，上颌后牙多处缺失，通过在腭部植入四颗微型种植体并借助哈斯改良型矫治器进行治疗。在扩弓期间，观察到切牙间出现间隙，这是缝线分离的首个临床迹象。纠正反合后，通过上颌咬合片证实了腭部的扩弓效果。因此，评估表明该技术是有效的，并且应该开展新的科学研究以进一步拓展该领域。关键词：矫治器；生物力学；种植体；错颌畸形
