Fifty consecutive cases presenting with unerupted maxillary incisors at orthodontic clinics were recorded and progress of the unerupted tooth followed up over a 4-year period following the exposure of the unerupted tooth (including removal of supernumerary tooth, etc., if present). The occlusal level, rotation, tilting, and general appearance were assessed at the conclusion of the investigation and the results are presented in this report. The earlier the removal of the causative factor preventing eruption of the incisor the better is the prognosis, and it is suggested that all teeth that have not erupted 6 months after the normal eruption date should be subject to radiological examination to ascertain any possible cause for the delayed eruption.
记录了在正畸诊所就诊的50例上颌切牙未萌出的连续病例，并在未萌出牙暴露后（如有额外牙等则包括拔除额外牙等操作）的4年期间对未萌出牙的进展进行了随访。在调查结束时评估了咬合平面、旋转、倾斜和整体外观，并将结果呈现在本报告中。越早去除阻碍切牙萌出的病因，预后越好，建议所有在正常萌出日期后6个月仍未萌出的牙齿都应接受放射学检查，以确定任何可能导致萌出延迟的原因。
