This paper presents an intuitive nose surgery planning and simulation system, using 3D laser scan image and lateral X-ray image, to provide high quality prediction of the postoperative appearance, and design the patient specific prosthesis model automatically. After initial registration, the internal surface of soft tissue at the nose region was generated(More)
PURPOSE The aim of this study was to examine the possible association between different grades of joint effusion (JE) and osteoarthritis (OA) in temporomandibular joint (TMJ) anterior disk displacement without reduction (ADDwoR). MATERIAL AND METHODS A sample of 101 female patients 20-40 years of age with unilateral TMJ ADDwoR were retrospectively(More)
PURPOSE To establish a three-dimensional finite element model of mandible with dental implants for immediate loading, which will provide a basis for study of the biomechanical characteristics of the immediate loading implant-bone interface. METHODS A female edentulous mandible was adopted for CT scanning, the scanned data were saved with the form of(More)
OBJECTIVE To evaluate a finite element method (FEM) for analysis of the cranial-facial morphology. METHODS The two-dimensional finite element analysis system was established and used to analysis the lateral side morphology of the soft tissue by the change of each finite unit of the soft tissue in a X-ray cranial-facial lateral cepholometrics film.

OBJECTIVE To evaluate the usefulness of two- dimensional (2D) and three-dimensional (3D) computed tomography (CT) in the identification and classification of Le Fort type fractures. METHODS Sixty-two patients with different types of Le Fort fractures underwent CT scanning and 3D-CT reconstruction. The data were analyzed by multiplanar reconstruction(More)
PURPOSE The purpose of this study was to investigate the maxillofacial morphologic characteristics of children with complete unilateral cleft lip and palate (UCLP) with and without surgical correction and better understand the relation between surgery and inhibition of maxillary growth. MATERIAL AND METHODS Lateral cephalometric radiography was performed(More)
OBJECTIVE To discuss the application of MRI in indirect temporomandibular joint injury without condylar fracture. METHODS MRI examination on temporomandibular joint was conducted in 28 patients with indirect injury to temporomandibular joint without condylar fracture. The scanning sequence included T(1)WI, PDWI on oblique sagittal section at both open and(More)
