Three-dimensional virtual treatment planning has greatly enhanced the efficiency and accuracy of dentofacial deformity correction through orthognathic surgery [1]. Moreover, the advent of rigid internal fixation has allowed a change in this classical sequence. Performing mandibular surgery first presents several advantages and surgeons must consider some indications in order to achieve better results, and the ability of the surgeon to reproduce the treatment plan in the operating room is essential [2]. Most of orthognathic surgery treatment plan has been performed by traditional sequence, but the surgery itself was performed using an inverted sequence. However, repositioning the lower jaw first during three-dimensional virtual planning, as well as in actual surgery, can be really advantageous. The purpose of this paper is to suggest a protocol for double-jaw orthognathic surgery repositioning the mandible first in both three-dimensional virtual planning and surgery itself.
