상악 매복 견치의 교정학적 고찰

Orthodontists, in evaluating maxillary impactd canines, must take into consideration the etiology of the problem. First, the possible etiologic factors must be eliminated. Thus some cases can be treated with orthodontic treatment alone without surgical trauma following window opening etc. Now, two cases are reported, which were treated without surgical intervention. Sometimes, impacted canine can be included in a plan for tooth removal due to its severe impaction and displacement. In such case, first premolar can be substituted for canine. One case which was treated by substituting maxillary first premolar for maxillary impacted canine is reported.
