Does Head and Neck Posture Affect Cone-Beam Computed Tomography Assessment of the Upper Airway?
Kevin Coppelson, MD, DDS; Isabella Summersgill, BS; David Hatcher, DDS, MSc; Gloria Nguyen, PA-S; Hilary Pada, DMD; Hal Stewart, DDS; Tim Herre, DDS; Michael Hansen, DDS; Soroush Zaghi, MD
Radiographic analysis is often used as a screening tool to assess for risk of sleep-related breathing disorders. This study aimed to address 2 questions: (1) Does head posture significantly affect the minimum cross-sectional area (MCA)? and (2) Is the NBC3 (nasion-basion-C3) angle a reliable measurement to control for alteration of head position in cone-beam computed tomography (CBCT) scans?
The Mystery of the Anterior Open Bite — Is It Really the Teeth?
Dr. Dania Tamimi
One of the vexing issues that may arise in the orthodontic practice is the relapse or change of the bite a few months or years after the completion of treatment. While it is tempting to consider a dentoalveolar etiology, the reality is many of these bite changes have etiologies that lie outside the dentoalveolar complex...
Imaging Pearls: When to Recruit the Third Dimension and How to Maximize your Yield from Radiographic Studies
Zubad Newaz, DDS
Both two- and three-dimensional imaging have great utility in dental diagnostics, each with their advantages and limitations. Radiology has the ability to not only answer questions about disease or abnormalities but also to provide anatomic information that is essential to proper diagnosis, treatment planning, and treatment delivery...
Imaging of the Temporomandibular Joint
Drs. Dania Tamimi, Husniye Demirturk Kocasarac & Shaza Mardini
The temporomandibular joint (TMJ) is a unique structure as it is the only diarthroidal synovial join in the body. It is continuously loaded, even when not functioning, and needs to be biomechanically sound in order to withstand the high mechanical loading that it is subject due during function. This article will discuss the anatomy and function...
Considerations for Use of Cone Beam Computed Tomography in Orthodontics
Shikha Rathi, BDS, MS, and David Hatcher, DDS, MSc
Abstract: The intent of this article is to identify clinical presentations that may benefit from an investigation with a cone beam computed tomography scan. These indications include dolichofacial growth pattern, mandibular asymmetry, acquired change in bite, impactions, craniofacial malformations, TMD and patients with suspected sleep disorders.
High Value Scenarios for CBCT Imaging in Orthodontics
Drs. David C. Hatcher & Shikha Rathi
Imaging is utilized in orthodontics as a tool to acquire anatomic information for diagnosis, treatment planning and treatment assessment. CBCT, a widely available 3 dimensional imaging technique, provides an anatomic accuracy that is not achievable with conventional panoramic and cephalometric imaging and therefore has the potential to have unique clinical value in selected clinical scenarios...
Advancing Technologies in Virtual Planning and Guided Execution
Richard F. Jackson
This topic reflects the accelerating changes that are occurring both in dentistry and medicine. It reminds me of the brand new book by the NY Times editor and best-selling author, Thomas Friedman, titled "An Optimist Guide to Thriving in the Age of Acceleration". My topic, "Virtual Planning and Guided Surgery" reflect these accelerations that are taking place today...
Patient Specific Modeling and Clinical Applications
Drs. David C. Hatcher & Shikha Rathi
One of the goals of digital technology, besides improved diagnostics, has been to create and interact with the virtial dynamic patient-specific model that can be used for a variety of therapeutic endeavors. This anticipated process begins with imaging the patient with the appropriate devices required to meet the diagnostic challenge and then producing a patient specific...
