초록
성장기 아동의 ClassII 부정교합에서 과도한 성장의 억제, 미약한 성장의 촉진으로 성장 시기에 적절히 치료하는 것이 가장 효과적이며 좋은 치료 방법이다. 이러한 방법중 가장 적절히 쓰이는 장치 중 Cervical headgear의 사용을 들수 있으며 악골에 효과적으로 적용된다. 그러나 장치의 부작용이라 할 수 있는 수직적 성장의 과잉을 볼 수 있는데 이에 대해 많은 선학들의 연구가 시행되어 왔다. 본 연구는 Cervial headgear의 상하악골에 대한 효과를 분석하고 Lover facial height를 기준으로 증가군(>0)과 증가하지 않은 군 (
This study was to investigate the horizontal & vertical bone change pattern when using cervical headgear in Class II malocclusion of growing children and compared the skeletal features between the group with increased lower facial height and the group without increase in lower facial height. The results are as follows ; 1. Forward growth of maxilla was inhibited, downward tipping of anterior palatal plane could be seen and distal movement of maxillary first molar was observed. 2. There was relative forward movement of Mandible against the Maxillary cranial base, and relative forward movement of mandibular 1st molar against the Maxilla and vertical increase due to alveolar growth of Mandible. 3. There was significant increase in anterior and posterior facial heights but the ratio of facial height showed no significant difference. 4. The group with increased lower facial height has shorter ramus length, than the smaller palatal plane angle, and more distal movement of Maxillary 1st molar than the group without increase Ha-young Hyun
