If the diastema is too big, the size harmony is important.A small artificial tooth added in the diastema is not good . 如果缝隙太宽,要注意大小协调,中间加一小塑料牙是不良设计。
A clinical examination revealed a moderate midline diastema between maxillary central incisors. 临床检查：上中切牙间中缝，中度大小。
Afterward, the mice were fed a soft diet and the transplants monitored.Just three weeks later teeth could be clearly identified in the diastema. 仅仅三个星期之后，就可以在牙间隙清楚看到牙齿的形成。
The effects on permanent maxillary incisors were found in approximately half of the patients including uneruption, ectopic eruption, and diastema. 有半数以上病患的门齿萌发会受影响，其影响包括阻碍门齿萌发、门齿异位萌发以及造成过大的齿缝间隙。
This paper reports a case on diastema closure in anterior teeth that was successfully treated using gingival recontouring and composite resin restorations. 本文就成功应用牙龈成形方法，以复合树脂关闭前牙间隙做一病例报道。
The purpose of this paper is to describe a case report in which the diastema closure was accomplished using direct adhesive restorations and gingival tissue recontouring. 本文旨在利用牙龈再成形方法，以复合树脂直接关闭前牙间隙做一病例报道。
