Effects of monocortical and bicortical mini-implant anchorage on bone-borne palatal expansion using finite element analysis

Bicortical mini-implant anchorage results in improved mini-implant stability, decreased mini-implant deformation and fracture, more parallel expansion in the coronal plane, and increased expansion during bone-borne palatal expansion. However, the depth of bicortical mini-implant anchorage was not significant.
