Joint Cephalometric Experts Group 2011
Wednesday, November 9, 2011 at 6:30 PM - Friday, November 11, 2011 at 12:00 PM (EST)
Intercontinental Suites Hotel ask for CASE JCEG
A link with the past-A promise for the future.
Purpose: To map the transition from 2D cephalometrics to 3D cone beam imaging for assessment of orthodontic outcomes as well as diagnosis and treatment planning. To facilitate the transition from plaster models to 3D digital study casts.
In 2001, the introduction of low cost, low radiation dose, high resolution cone beam computed tomography in clinical orthodontics created the potential for new discoveries in craniofacial biology and facial growth. This technology provides researchers and clinicians with the tools needed to study 3D changes in craniofacial anatomy associated with the growth process and clinical care. In the 20th century, radiographic cephalometry was a pioneering advance that led to many fundamental insights into the effects of orthodontic treatment. CBCT imaging promises similar advances in the 21st century.
In 2010, new low cost scanners are able to digitize plaster models and/or dental impressions to produce digital study casts. The high quality and low cost of these new devices makes the prospect of digital study casts practical for orthodontists interested in keeping pace in the age of technology. However, as with CBCT, the steep learning curve combined with the desire of manufacturers to sell product necessitates a forum for unbiased discussion of the pros and cons of adopting this technology in orthodontics. Therefore, this year JCEG III will also include 3D model scanning in the discussion matrix.
Shuttle Service: Please note, The Intercontinental Suites Hotel will provide one round trip per day. The shuttle on Thursday morning will leave for Dively Center at 7:30am.

New this year!! Pre JCEG 3D Software Course Wed 9am to 4 pm at the Dively Center.
This 6 hour workshop and will requre participants to bring a laptop computer capable of running high end graphics based programs.
Latest Update from Lucia:
The recently updated image analysis tools run more efficiently in Mac or Linux. A dual boot ( Boot camp) mac/linux would be ideal, but a mac or a windows laptop are ok for this workshop. Presenters will bring USB drives for each attendee. Also please check the NAMIC website that has further info and agenda for the workshop:
Please contact Lucia at firstname.lastname@example.org for more details. Below is the workshop description.
Background: This workshop will highlight the use of publicly available software for dental applications of 3D virtual models from Cone-beam CT volumes. The ability to visualize the face in 3D does not imply the ability to quantify growth or treatment changes. 3D structural shape analyses continue to mandate a multidisciplinary collaborative team including clinician researchers, shape analysis and statistical modeling experts. Purpose: The intent of this workshop is to update researchers on the development and application of 3D quantitative analyses. In this workshop researchers will learn: 1) underlying statistical methods used; 2) implementation of the software that allows construction of 3D averages; and 3) quantitative analysis of differences in shape. Speakers: 1. Softwares and statistical analysis of shape; 2. Quantification of 3D craniofacial morphology. Outcomes/significance: The workshop will allow participants to understand the use of 3D quantitative methodology across patients with different facial morphology and for longitudinal assessments. Potentially, this workshop will enhance a more generalized use of quantitative 3D data. Attendees are requested to bring PC laptops and will be sent URLs to download relevant 3D analysis software programs in advance of the workshop. The workshop participants will be presented with the opportunity to use a number of the software packages discussed.
The following are the official working groups of JCEG along with a short description of the scope of the group:
Superimposition/Outcomes Assessment --Identify biologically stable and relevant features for superimpositionof 3D volumes.
Registration- Establish a set fiducial landmarks within the volume to insure the integrity of the image and to allow landmark data derived from the imageto be stored in a known coordinate system.
3D Morphologic Standards/Diagnosis and Treatment Planning- Combine the existing 3D Bolton Landmark data withsurface data acquired from CBCT to create 3D graphical standards thatcan be used for orthodontic diagnosis and treatment planning-.
Database of 3D CT images - Develop and implement a database of 3D images forcraniofacial research.
3D Digital Models- Establish guidlelines for 3D digital models that facilitates free exchange of model data among practitioners. Identify useful 3D tools for model analysis.

Mark Hans, DDS, MSD
The purpose of J.C.E.G. is to map out a plan for the transition from 2D cephalometrics to 3D cone beam imaging AND 3D models for assessment of orthodontic outcomes, as well as diagnosis and treatment planning.
