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 کاملChanges of lip morphology following mandibular setback surgery using 3D cone-beam computed tomography images
BACKGROUND The aims of this study are to evaluate the lip morphology and change of lip commissure after mandibular setback surgery (MSS) for class III patients and analyze association between the amount of mandibular setback and change of lip morphology. METHODS The samples consisted of 14 class III patients treated with MSS using bilateral sagittal split ramus osteotomy. Lateral cephalogram ...
متن کاملSoft tissue response to mandibular advancement using 3D CBCT scanning.
This prospective longitudinal study assessed the 3D soft tissue changes following mandibular advancement surgery. Cranial base registration was performed for superimposition of virtual models built from cone beam computed tomography (CBCT) volumes. Displacements at the soft and hard tissue chin (n = 20), lower incisors and lower lip (n = 21) were computed for presurgery to splint removal (4-6-w...
متن کاملSkeletal displacements following mandibular advancement surgery: 3D quantitative assessment
Objective: To evaluate changes in the position and remodeling of the mandibular rami, condyles and chin with mandibular advancement surgery through the superimposition of 3D Cone-Beam Computed Tomography (CBCT) models. Methods: This prospective observational study used pre-surgery and post-surgery CBCT scans of 27 subjects presenting skeletal Class II with normal or horizontal growth pattern. A...
متن کاملRetrospective analysis of the effects of orthognathic surgery on the pharyngeal airway space.
PURPOSE Dentofacial deformities can be defined as defects in the growth and development of facial bones, mainly the maxilla and mandible. Such deformities can change the dimension and function of the pharyngeal airway space and orthognathic surgery is the treatment of choice. The aim of this study was to evaluate changes in the pharyngeal airway space after orthognathic surgery and test the abi...
