Assessment 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...
متن کامل3D Mandibular Superimposition: Comparison of Regions of Reference for Voxel-Based Registration
INTRODUCTION The aim was to evaluate three regions of reference (Björk, Modified Björk and mandibular Body) for mandibular registration testing them in a patients' CBCT sample. METHODS Mandibular 3D volumetric label maps were built from CBCTs taken before (T1) and after treatment (T2) in a sample of 16 growing subjects and labeled with eight landmarks. Registrations of T1 and T2 images relati...
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 کاملMandibular response after rapid maxillary expansion in class II growing patients: a pilot randomized controlled trial
BACKGROUND The aim of this pilot randomized controlled trial (RCT) was to evaluate the sagittal mandibular response induced by rapid maxillary expansion (RME) therapy in mixed dentition patients with class II malocclusion, comparing the effects of bonded RME and banded RME with a matched untreated class II control group. METHODS This RCT was designed in parallel with an allocation ratio of 1:...
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...
