Abstract

When we notice missing maxillary incisors, how to restore the extraction site is a difficult decision. Usually, we restore this kind of tooth with conventional fixed partial denture or implant prosthesis. However, some literatures present another solution: tooth substitution with proximal tooth by orthodontic force. In this paper, we put together few cases treated in Chi-mei orthodontic department, and we also discover some problems in the process of the orthodontic treatment. Hence, if we meet a case alike to these, the experiences we had can help to improve the orthodontic results.
