Computer-Assisted Design and Manufacture of Implants in the Late Reconstruction of Extensive Orbital Fractures

摘要

Objective: To evaluate the use of computer-assisted designed and manufactured (CAD/CAM) orbital wall and floor implants for late reconstruction of extensive orbital fractures.Methods: We performed a retrospective data review on 29 patients treated for extensive orbital fractures from January 1, 1997, through December 31, 2007, at the University College London Hospitals. The use of a CAD/CAM technique based on cross-sectional computed tomographic scans, generating an accurate ste-reolithographic model, enabled surgeons and technicians to plan and create the best dimension and position of the implant. Sheet titanium was then
