在治疗计划过程中,提取决策至关重要。作为一种治疗选择,在咬合缺乏面部和谐和稳定性的情况下,应考虑拔牙。治疗目标,这种错牙合,美学考虑,和生长模式都是影响不对称提取的因素。在大多数情况下,当牙齿之间存在明显的中线差异或不对称连接时,需要拔除前磨牙。前磨牙,它们是第一颗萌出的牙齿,在咀嚼时占据后面的位置,比其他恒牙更容易受伤。去除第二磨牙的最佳时间是在磨牙之间的连接正常化或可以纠正主要的前交叉咬合时。
During the treatment planning process, extraction decisions are crucial. As a therapy option, the extraction of teeth should be considered in instances where there is a lack of facial harmony and stability in the occlusion. Treatment aims, the kind of malocclusion, aesthetic considerations, and growth patterns are all factors that influence asymmetric extraction. For the most part, premolar extractions are required when there is a significant midline difference or an asymmetrical connection between the teeth. Premolars, which are the first teeth to erupt and occupy the posterior position in chewing, are more vulnerable to injury than other permanent teeth. The optimal time to remove a second molar is at the moment when the connection between the molars has normalized or when a major front cross-bite can be remedied.
