Orthodontic movement of the teeth is accompanied by the remodeling of what to permit movement of the tooth: PDL, alveolar bone, alveolar bone proper, or cementum?
- Alveolar bone proper. This movement effects the PDL, stretching it on one side (tension) and compacting it on the other (compression). When bone is resorbed, the fibers in the PDL become established to their new parameters and hold the tooth in its new position after all bone remodeling has occurred. PDL likes to be a specific width!
