A borderline case presents with mild skeletal disharmony or orthodontic problems due to arch length discrepancy and migration of teeth or a combination of these but is masked by a balanced soft tissue relationship. This case report describes one such borderline case of a 13-year-old girl who complained of irregularly placed upper and lower front teeth. Extraoral examination revealed balanced soft tissue with a mild convex profile, competent lips, and an average nasolabial angle. Intraorally, she had mixed dentition with flush terminal in primary molars and a class I relation in the permanent molars, severe crowding in the lower anterior, and congenitally missing permanent right laterals. A nonextraction protocol was followed, harnessing the pubertal growth spurt to alleviate the crowding and thereby preserving the soft tissue harmony.

临界病例表现为轻度骨骼不协调或因牙弓长度差异、牙齿移位或两者共同作用导致的正畸问题,但被平衡的软组织关系所掩盖。本病例报告描述了一名13岁女孩的此类临界病例,该女孩主诉上下前牙排列不齐。口外检查显示软组织平衡,面型轻度凸,唇部功能正常,鼻唇角正常。口内检查发现,她处于混合牙列期,乳牙磨牙末端平齐,恒牙磨牙为I类关系,下前牙严重拥挤,先天性缺失右上侧切牙。采用不拔牙矫治方案,利用青春期生长突增来缓解拥挤,从而保持软组织协调。
