Posttreatment stability is one of the challenges facing orthodontists today. Relapse of the mandibular anterior segment during the postretention period is perhaps the most predictable and frustrating of all orthodontic relapses. This type of relapse is sometimes erroneously construed as a sign of inappropriate treatment or evidence of misdiagnosis or incorrect mechanics. This article reviews mandibular incisor postretention stability outcomes in the setting of different treatment techniques and different ages of beginning orthodontic treatment. Mandibular incisor relapse is almost inevitable, regardless of orthodontic techniques and timing of orthodontic treatment. However, mandibular incisor relapse might be reduced when palatal expansion is combined with prolonged retention.
治疗后的稳定性是当今正畸医生面临的挑战之一。保持期下颌前段的复发可能是所有正畸复发中最可预测且最令人沮丧的。这种类型的复发有时会被错误地解释为治疗不当的迹象或误诊或矫治力学不正确的证据。本文回顾了在不同治疗技术和不同正畸治疗起始年龄情况下下颌切牙保持后的稳定性结果。无论正畸技术和正畸治疗时机如何，下颌切牙的复发几乎是不可避免的。然而，当腭扩展与延长保持相结合时，下颌切牙的复发可能会减少。
