SPONTANEOUS CORRECTION OF PATHOLOGICAL MIGRATION FOLLOWING PERIODONTAL THERAPY

Two case reports illustrate spontaneous correction of pathologic migra tion following periodontal therapy. In one case, the displaced teeth w ere repositioned without orthodontic appliances after nonsurgical and surgical periodontal treatment. In the other case, closure of a diaste ma occurred following only nonsurgical therapy. The predictability of these findings needs further investigation. A discussion of possible r easons for this type of tooth movement is included.
