In cases with an end-on-class II molar relationship, extraction of the maxillary first premolar and the mandibular second premolar may be selected as treatment options (# 14, 24, 35, 45 extraction) to improve the molar relationship. Before the orthodontic treatment begins, premolars are extracted first and the orthodontic treatment may be started. However, in some cases, timing of extracting the maxillary and mandibular premolars may be different for specific purposes. 1) Extracting maxillary first premolar first if there is a high risk of Temporomandibular Joint Disorder
If the patient's lower jaw is unstable and the CO-CR discrepancy is large so Idiopathic condylar resorptio…
The position of the maxillary anterior teeth is one of the most important factors when evaluating the results of orthodontic treatment. In the case of severe crowding, even if the tooth was judged to be severely crowded, it was found that excessive extraction space remained when leveling was finished. The teeth were arranged ruggedly back and forth, but the teeth were inclined inward, so lack of space was not actually that very serious. In this case, contrary to the dentist's intention, the maxillary anterior teeth are lingually positioned, or additional effort is needed to prevent them. We measure ALD in a variety of ways to minimize these errors, for example, continuous wire measuring …

좋은 칼럼입니다~ ^^ 저는 44-55 ext 나 44-00 ext 둘 중에 고민 되는 증례에서는 턱관절질환이 의심시에는 상악을 먼저 발치할 수 있다고 생각합니다. 다만 하악 발치가 꼭 필요하다고 생각되는 증례에서는 하악을 먼저 빼고 어떻게 해서든 molar key를 개선시켜 가면서 치료해야된다고 생각합니다. 이 전략은 상악에도 크라우딩이 심해서 초반부터 상악도 같이 빼야하는 증례에서도 상악의 anchor를 mini-screw로 잘 보존하면서 molar key를 개선해 나가야한다고 생각합니다~ 좋은글 감사합니다 ^^

Good article. I agree with you. Sometimes timing of extraction matters in Class II cases.
