Superimposition of 3D cone-beam CT models in orthognathic surgery.
INTRODUCTION: Limitations of 2D quantitative and qualitative evaluation of surgical displacements can be overcome by CBCT and three-dimensional imaging tools. OBJECTIVES: The method described in this study allows the assessment of changes in the condyles, rami, chin, maxilla and dentition by the comparison of CBCT scans before and after orthognathic surgery. METHODS: 3D models are built and s...
متن کاملSuperimposition of 3D cone-beam CT models of orthognathic surgery patients.
OBJECTIVES To evaluate the registration of 3D models from cone-beam CT (CBCT) images taken before and after orthognathic surgery for the assessment of mandibular anatomy and position. METHODS CBCT scans were taken before and after orthognathic surgery for ten patients with various malocclusions undergoing maxillary surgery only. 3D models were constructed from the CBCT images utilizing semi-a...
متن کاملSuperimposition of 3-dimensional cone-beam computed tomography models of growing patients.
INTRODUCTION The objective of this study was to evaluate a new method for superimposition of 3-dimensional (3D) models of growing subjects. METHODS Cone-beam computed tomography scans were taken before and after Class III malocclusion orthopedic treatment with miniplates. Three observers independently constructed 18 3D virtual surface models from cone-beam computed tomography scans of 3 patie...
متن کاملA method for mandibular dental arch superimposition using 3D cone beam CT and orthodontic 3D digital model
OBJECTIVE The purpose of this study was to develop superimposition method on the lower arch using 3-dimensional (3D) cone beam computed tomography (CBCT) images and orthodontic 3D digital modeling. METHODS Integrated 3D CBCT images were acquired by substituting the dental portion of 3D CBCT images with precise dental images of an orthodontic 3D digital model. Images were acquired before and a...
متن کاملAssessment of mandibular advancement surgery with 3D CBCT models superimposition.
OBJECTIVES: To assess surgery and short-term post-surgery changes in the position of the condyles, rami and chin after mandibular advancement. METHODOLOGY: Pre-surgery (T1), 1 week post-surgery (T2), and 6 week post-surgery (T3) CBCT scans were acquired for 20 retrognathic patients with short or normal face height. 3D models were built and superimposed through a fully automated voxel-wise meth...
