Three-Dimensional Computer-Assisted Orthognathic Surgery

Abstract

This computer-assisted orthognathic surgery system helps to improve surgical planning, reduce surgical difficulty, facilitate positioning and fixation of the maxillomandibular complex, and improve outcome.

Three-dimensional surgical simulation improves the planning for correction of facial prognathism and asymmetry: A qualitative and quantitative study

“…Lin et al . proposed a protocol for assessing the surgical simulation, guide positioning, intraoperative navigation, and outcome validation provided by computer-assisted surgery systems3839. The 3D virtual surgery combined with navigation was proposed and suggested that simulation-guided navigation makes accurate postoperative outcomes possible for maxillary repositioning in orthognathic surgery404142434445.…”

Intraoperative navigation for single-splint two-jaw orthognathic surgery: From model to actual surgery

“…However, a better treatment outcome is obtained, especially for patients with complicated deformity and asymmetry. In our experience, postoperative facial symmetry and harmony have much been improved (Lin et al, 2015). The cost and time are expected to be reduced in the future because of improvements in technology and experience.…”

Guías y miniplacas personalizadas: un protocolo guiado para cirugía ortognática

“…Son varios los autores que han presentado sistemas alternativos a las FO clásicas para realizar la transferencia intraoperatoria del plan quirúrgico virtual [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23] . Estos protocolos suelen aplicarse para posicionar el maxilar superior o para facilitar la relación céntrica condilar, y se podrían clasificar en 2 grupos según el sistema de osteosíntesis utilizado: a) grupo 1: reposicionamiento exclusivo: uso de diferentes férulas aplicadas en distinto tiempo o asistido por navegación 8-16 para posicionar el fragmento maxilar; posteriormente la osteosín-tesis se realiza con miniplacas convencionales, y b) grupo 2: reposicionamiento y osteosíntesis simultánea mediante el uso de miniplacas de titanio personalizadas con la ayuda de guías de brocado/osteotomía o sistemas de navegación [17][18][19][20][21][22][23] .…”
