OBJECTIVE
To evaluate the clinical effect of semi-attached quad-helix appliance in expanding the narrow maxillary arches in patients with cleft lip and palate.
METHODS
15 cases with cleft lip and palate were selected and treated by semi-attached quad-helix appliance. Before, during, and after treatment, the dental arch width between cuspid, the first premolar and first molar were measured.
RESULTS
The upper dental arches of all patients were expanded effectively in about five months. After orthodontic treatment, the upper dental arches were expanded, and the teeth were alined regularly, which provided good conditions for alveolar bone grafting.
CONCLUSION
The semi-attached quad-helix appliance with the fixed orthodontic treatment can expand the narrow maxillary arches in patients with cleft lip and palate effectively and conveniently.
目的
评估半固定式四螺旋矫治器扩宽唇腭裂患者狭窄上颌牙弓的临床效果。
方法
选取15例唇腭裂患者，采用半固定式四螺旋矫治器进行治疗。在治疗前、治疗期间及治疗后，测量尖牙、第一前磨牙和第一磨牙之间的牙弓宽度。
结果
所有患者的上颌牙弓在约5个月内均得到有效扩宽。正畸治疗后，上颌牙弓扩宽，牙齿排列整齐，为牙槽骨植骨提供了良好条件。
结论
半固定式四螺旋矫治器联合固定正畸治疗能有效、便捷地扩宽唇腭裂患者狭窄的上颌牙弓。
