Because I have recently treated several cases of patients who asked for Invisalign, but due to the need for extractions, were rejected by several doctors, or recommended that patients change to traditional braces, so I feel the need to do a little bit of simple popularization of Invisalign technology for patients with extractions: 1, Invisalign can be used for the majority of extractions case treatment! 2, Invisalign will not prolong the course of orthodontic treatment! Wuhan University Stomatology Hospital Orthodontics Xia Dahong 3, Invisalign is not a fool’s errand, the design of its extraction case program and the realization of the treatment of the doctor’s requirements than traditional orthodontics! 4, No bracket invisible orthodontics does not reject the traditional wire orthodontics, if necessary, can be combined with the traditional orthodontic techniques; for example, in the posterior teeth area, localized on the wire! 5, Article 4 above does not indicate that every patient needs to use wire; on the contrary, if properly controlled, most patients can be invisible orthodontics alone to complete the treatment! As the first batch of Invisalign certified doctors in Hubei, and the first certified instructor, I am pleased to see the vigorous development of invisible orthodontic technology and the wide range of applications! But also noted that there are some problems: 1, abuse, many doctors who do not have mastery of Invisalign technology, and even the lack of orthodontic general knowledge, no basic orthodontic training of Invisalign technology as a fool’s errand technology applied to patients. The result must be as tragic as when many charlatan doctors used porcelain teeth for orthodontics! 2, won’t use because won’t use, so refuse to use! So that part of the patients who can use invisible orthodontics did not enjoy the pleasant orthodontic experience brought by invisible orthodontics. At present, due to the price, Invisalign mainly applies to some patients with good economic conditions, so remind this part of the patients and friends, before making a decision, please consider carefully, so as not to jeopardize your interests!
