【Abstract】 Objective: To develop a computer-aided three-dimensional design software and laser scanning technique for the restoration of unilateral orbital defect. Method: By laser scanning apparatus plaster face model and the acquired primitive face point data were scanned; with the three-dimensional design software the point data were reconstructed to one smooth face surface image and the data of the defect of the orbital tissue were obtained from the normal contralateral tissue data by software. Results: The face-model data obtained by laser scanning apparatus was distinct and precise; the Digisurf retrograde engineer software succeeded to fulfill the computer-aided design for restoration of unilateral orbital defect. Conclusion: The laser scanning technique and three-dimensional design software can be used in the computer-aided design of the unilateral orbital defect restoration.更多还原
