摘要

上顎側門齒是第二常見先天缺失的牙齒。針對這類型病人主要有兩大方向的矯正治療方式：一是騰出缺失的側門牙空間，並且日後利用植牙或是牙橋方式恢復外觀；另一則是關閉空間，利用犬齒取代原先側門齒的位置。治療計劃需根據患者個人咬合狀況、相鄰的牙齒關係、犬齒的大小與美觀等考量來制定。本案例為一12歲女童檢查發現有雙側先天側門牙缺失情形，經評估後選擇騰出空間的矯正方式，待日後女童顎骨與咬合穩定後做最後的贋復治療。

Maxillary lateral incisor is the second most common congenitally absent teeth. Two treatment options exist for treating patients with this problem. One option is to open space to replace the missing tooth; the other is to close the space and substitute the canine for the missing lateral incisor. Selecting the appropriate treatment plan depends on the malocclusion, the tooth-size relationship, and the size and esthetics of the canine. The purpose of this article is to present a case of 12-year-old girl with congenital missing maxillary lateral incisors and the treatment strategy to open the space and maintain the space for prosthetic treatment after mature.
