Maxillary midline diastema is a common aesthetic problem in mixed and early permanent dentitions. The space can occur either as a transient malocclusion or created by developmental, pathological or iatrogenical factors. Many innovative therapies varying from restorative procedures such as composite build-up to surgery (frenectomies) and orthodontics are available. Although literature says every frenectomy procedure should be preceded by orthodontic treatment, we opted for frenectomy technique without any orthodontic intervention. Presented herewith is a case report of a 9-year-old girl with a high frenal attachment that had caused spacing of the maxillary central incisors. A spontaneous closure of the midline diastema was noted within 2 months following frenectomy. The patient was followed up for 4 months after which the space remained closed and there was no necessity for an orthodontic treatment at a later stage.
上颌中线牙缝是混合牙列和恒牙早期常见的美学问题。该间隙可能是暂时性错牙合，也可能由发育、病理或医源性因素导致。有许多创新疗法可供选择，从复合树脂充填等修复程序到手术（系带切除术）和正畸治疗。尽管文献表明每次系带切除术前都应进行正畸治疗，但我们选择了不进行任何正畸干预的系带切除术技术。本文报告了一名9岁女孩的病例，其系带附着过高导致上颌中切牙出现间隙。在系带切除术后2个月内，中线牙缝自发关闭。对该患者进行了4个月的随访，此后间隙保持关闭，后期无需进行正畸治疗。
