Tissue responses resulting from tooth movement surgically assisted by corticotomy and corticision in rats.

Objective: To compare the histological responses in corticotomy- and corticision-assisted tooth movement.

Materials And Methods: Ninety Wistar rats were divided into three groups: C (control-tooth movement only), CT (tooth movement + corticotomy), and CI (tooth movement + corticision). Surgeries were performed on the vestibular and lingual cortical bone of the maxillary first molar.
