The etiology of late lower arch crowding alternative to mesially directed forces: a review.
The causes of late crowding in the lower arch alternative to mesially directed forces are reviewed under the headings: late mandibular growth, skeletal structure and complex growth pattern, soft tissue maturation, periodontal forces, tooth structure, occlusal factors, and connective tissue changes. A multifactorial basis for late lower arch crowding seems likely.
