Eruption of a first permanent molar ectopically is a common occurrence in any office in which a significant number of children are treated. Approximately 65 per cent of the ectopically erupting molars will self-correct. It is imperative that the dentist closely examine all preschool children to determine the possibility that the condition will occur and follow the child closely to determine the subsequent need for treatment. If clinical treatment is advisable the dentist can use a modified version of the Humphrey appliance to successfully and rapidly correct ectopically erupting molars with relative ease.
第一恒磨牙异位萌出在任何治疗大量儿童的诊所中都是常见现象。大约65%的异位萌出磨牙会自行纠正。牙医必须仔细检查所有学龄前儿童，以确定发生这种情况的可能性，并密切跟踪该儿童，以确定后续的治疗需求。如果建议进行临床治疗，牙医可以使用改良版的汉弗莱矫治器，相对轻松地成功快速纠正异位萌出的磨牙。
