Cone Beam Scanner

Carestream 9300 3D cone beam CT scanner

Our entire team at Hilliard & Dietrich Orthodontics strives to stay up-to-date with all the latest advances in orthodontic treatment in order to provide the safest and most effective treatment.  Because traditional 2-dimensional imaging can be inaccurate and limited in the information it provides, Cone Beam CT imaging is quickly becoming the standard of care in providing accurate, safe and exceptional orthodontic treatment. With this in mind, we are pleased to offer our patients the CS 9300 3D Cone Beam CT.  

The CS 9300 gives us the capability to take traditional 2D panoramic and cephalometric x-rays when indicated but also functions as a 3D Cone Beam CT scanner when a more accurate image is necessary.   The Cone Beam CT options are unlimited to allow us to focus in on a single tooth area for a much lower dose of radiation or expand the field of view to a larger area for more complex treatment diagnostics. Unlike with traditional imaging equipment, you don’t have to worry about receiving too much radiation exposure.  Even the largest field of view has approximately 90% less radiation than a traditional CT.

Orthodontists have historically relied on 2-dimensional x-rays in evaluating 3-dimensional structures. We are now entering a new age of technology in orthodontics. With Cone Beam CT imaging, we are able to ensure a more comprehensive orthodontic diagnosis, exceptionally accurate treatment planning and better outcomes for our patients by allowing for:

  • 3D views of vital structures
  • 3D evaluation of impacted tooth position and anatomy
  • TMJ assessments of condylar anatomy in all three dimensions
  • Orthognathic surgery treatment planning and growth assessments in true 1:1 imaging (traditional imaging can have 25-30% magnification distortion and inaccuracy)
  • Airway and sinus assessments (important for patients suffering from sleep apnea)
  • Planning for placement of dental implants for tooth restoration or orthodontic anchorage
  • Assessment of skeletal symmetry or asymmetry

 

Impactions:

Cone Beam CT scans provide a more accurate 3-dimensional assessment to provide more predictable treatment results while reducing the risks associated with any impacted tooth. These images improve our ability to:

  • Visualize an impacted tooth’s position in relation to surrounding vital structures and nearby teeth and their roots
  • Plan orthodontic movement of impacted teeth to minimize risk to the surrounding teeth and structures.
  • Better assess the risk of treatment or non-treatment based on more accurate 3-dimensional analysis

 

Sinus and Airway:

Volumetric data obtained from a CBCT survey can be used to visualize the sinuses and the entire airway path from the nasal and oral entrances to the laryngeal spaces for:

  • Identification of anatomical borders
  • Determination of infection and presence of polyps
  • Assistance in airway studies for diagnosis and treatment of obstructive sleep apnea
  • Calculation of actual volume of airway space
  • Determination of the point of airway constriction

 

TMJ:

Accurate evaluation of the temporomandibular joint (TMJ) has been difficult in the past due to the superimposition of other structures in conventional radiographs. With Cone Beam CT imaging, it is now possible to:

  • Assess the condylar anatomy of the TMJ without superimposition and distortion of the image
  • Obtain a true 1:1 imaging of the condylar structures for more accurate assessments
