Spontaneous Correction of Pathologic Migration Following Periodontal Therapy

Two case reports illustrate spontaneous correction of pathologic migration following periodontal therapy. In one case, the displaced teeth were repositioned without orthodontic appliances after nonsurgical and surgical peridoontal treatment. In the other case, closure of a diastema occurred following only nonsurgical therapy. The predictability of these findings needs further investigation. A discussion of possible reasons for this type of tooth movement is included.
