Infraocclusion occurs at an early age and becomes worse with age, causing increased damage in young children. Extraction of affected teeth is the preferred treatment modality for prevention of possible complications. It is rare for a primary molar to temporarily exhibit secondary failure of eruption, followed by regeneration of full eruptive capacity. This report was written to describe two patients who experienced spontaneous eruption of an infraoccluded primary molar at approximately 7 years of age. While watchful waiting is not always a suitable treatment option, we propose that extraction be deferred until the first permanent molar erupts, unless significant problems occur.
低位阻生在幼年时就会出现，且随年龄增长而加重，对幼儿造成更大损害。拔除患牙是预防可能出现并发症的首选治疗方式。乳牙磨牙暂时出现萌出继发失败，随后又恢复完全萌出能力的情况较为罕见。本报告旨在描述两名患者，其低位阻生的乳牙磨牙在大约7岁时自发萌出。虽然密切观察并不总是合适的治疗选择，但我们建议在第一恒磨牙萌出之前推迟拔牙，除非出现严重问题。
