治療齒列擁擠的病患除了拔牙的選擇之外,還可以利用配戴口內裝置將上顎大臼齒作遠心移動製造出空間,來改善擁擠的齒列並且達到正常的咬合位置,然而如何將所得到的空間完全用於前牙擁擠的改善,往往需要更完善的考量。本篇病例報告使用鐘擺式矯正裝置(pendulum)搭配切角式全口固定式矯正器(Tip-Edge Plus)不需藉助額外之口內外裝置來治療齒列擁擠的病患。(J. Taiwan Assoc. Orthod. 23(4): 32-41, 2011)
Using intraoral molar distalization appliance is one of the treatments of patients with crowding dentition besides extraction for crowding relief and achievement of normal occlusion. However, how to keep the space gained with the intraoral appliance for crowding relief is what we need to consider. In this paper, we use pendulum appliance combines ”cutting edge” brackets (Tip-Edge Plus) in these patients with crowing dentition without other auxiliary intraoraI or extraoral appliances. (J.
