Extrusion of teeth may be necessary in cases of delayed eruption, primary retention, traumatically intruded teeth, or subgingivally fractured teeth. Removable appliances are advantageous, as anchorage is not as tooth-dependant as in the case of fixed appliances. They are cost-effective, operator friendly, and a valuable treatment option to consider in cases where extrusion of anterior teeth in the transitional dentition is necessary. The purpose of this paper was to describe a simple, cost-effective technique using a removable appliance for extrusion of incisors in the transitional dentition.
在牙齿萌出延迟、乳牙滞留、牙齿受外伤嵌入或牙颈部折断的情况下，可能需要进行牙齿牵引。可摘矫治器具有优势，因为其支抗不像固定矫治器那样依赖牙齿。它们性价比高、操作简便，对于混合牙列期上前牙需要牵引的情况而言，是一种值得考虑的有效治疗选择。本文旨在描述一种使用可摘矫治器对混合牙列期切牙进行牵引的简单且经济有效的技术。
