Three-dimensional reproducibility of natural head position. DW Weber, DW Fallis, MD Packerc.

Date: May 2013 Source: American Journal of Orthodontics and Dentofacial Orthopedics, Volume 143, Issue 5, pp 738-744. Introduction: Although natural head position has proven to be reliable in the sagittal plane, with an increasing interest in 3-dimensional craniofacial analysis, a determination of its reproducibility in the coronal and axial planes is essential. This study was…

Multimodal registration of three-dimensional maxillodental cone beam CT and photogrammetry data over time. N Bolandzadeh, W Bischof, C Flores-Mir, P Boulanger.

Date: February 2013. Source: Dentomaxillofacial Radiology, Volume 42, Issue 2. Objectives: In recent years, one of the foci of orthodontics has been on systems for the evaluation of treatment results and the tracking of tissue variations over time. This can be accomplished through analysing three-dimensional (3D) orthodontic images obtained before and after the treatments. Since…

Three-dimensional airway evaluation in 387 subjects from one university orthodontic clinic using cone beam computed tomography. CC Chiang, MN Jeffres, A Miller, DC Hatcher.

Date: November 2012 Source: Angle Orthodontist; 82(6): pp 985-92. Abstract: Objective: To determine the linear, volumetric, and cross-sectional area measurements in a large sample of subjects seeking treatment in a university clinic of orthodontics. Materials and Methods: Cone-beam computed tomography (CBCT) scans from 387 patients were analyzed retrospectively. All scans were loaded into the 3dMDvultus…

The Facial Profiling of Malocclusions: The Promise of Emerging 3-Dimensional Technologies. C Wholley and M Walters

Date: 10-14 February 2012. Source: Australian Society of Orthodontists’ 23rd Congress 2012, Perth, Australia. Abstract: The assessment of facial profile, bite and underlying dental-skeletal discrepancies are critical in the diagnosis and treatment planning of malocclusions. In addition to the clinical evaluation, other records such as facial photography, dental impressions and cephalometry are routinely taken to…

Three-dimensional evaluation of changes in lip position from before to after orthodontic appliance removal. L Eidson, LHS Cevidanes, L Koerich de Paula, HG Hershey, G Welch, PE Rossouw.

Date: September 2012. Source: American Journal of Orthodontics & Dentofacial Orthopedics; Volume 142, Issue 3 , pp 410-418. Introduction: Our objectives were to develop a reproducible method of superimposing 3-dimensional images for measuring soft-tissue changes over time and to use this method to document changes in lip position after the removal of orthodontic appliances. Methods:…

Methods of Measuring the Three-Dimensional Face. NM Souccar, CH Kau.

Date: September 2012. Source: Seminars in Orthodontics; Volume 18, Issue 3, pp 187-192. Abstract: Three-dimensional surface imaging is a popular technique among orthodontists and maxillofacial surgeons. It allows the capture of the face in 3 dimensions and the measurement of distances, surfaces, and volumes. Many devices and analyses have been developed to reconstruct and accurately…

Thesis: Sexual Dimorphism in Soft Tissue Facial Form as captured by Digital Three-Dimensional Photogrammetry. SB Lim

Date: June 2012. Source: University of Pittsburgh, School of Dental Medicine, Master’s Thesis. Abstract: Sexual dimorphism in the head and neck area is a particular interest to orthodontists who manipulate the underlying hard tissue in order to alter the overlaying soft tissue. Hard tissue differences between the sexes have been well documented in the literature…
