Imaging

In order to create an ideal and detailed treatment plan; Dr. Amin and Dr. Vaziri need to have the best understanding of the position of your teeth within the bone and the position of the jaws within the skull. Not having the proper X-ray images and trying to come up with a treatment plan is like being in a dark room and trying to find the way out!

During your consultation appointment some X-ray images will be taken to provide the necessary information for your customized treatment plan. Below is a list of the most common radiographic images used in orthodontic practices:

Periapical

  • Small, high resolution, two dimensional image
  • Focused on a limited area, one or two adjacent teeth and their surrounding bone structure.
  • Orthodontists usually use it to evaluate the bone level supporting the teeth, to detect any abnormality on the roots of the teeth or for the placement of temporary anchorage devices.
  • A family dentist usually uses it to diagnose cavities and to provide root canal therapy.
  • Minimal exposure to radiation.

Disadvantage

  • Two dimensional.
  • Too many images are required to cover the whole mouth.

Panoramic

  • One of the most common radiographs taken in an orthodontic office.
  • Covers a broad area including both jaws, chin, all teeth, maxillary sinuses and part of the neck and the nose in one image.
  • Excellent tool for Dr. Amin Movahhedian and Dr. Hamed Vaziri to evaluate teeth development, chance of crowding or spacing before happening, find out if there is any missing, extra or impacted tooth in the bone, and position of the wisdom teeth related to other teeth.
  • Minimal exposure to radiation, about the same as four periapical images.

Disadvantages

  • Two dimensional
  • Images of the different structures may overlap each other.
  • Image of the objects in the picture may not be proportionate to their actual size.  
  • Lower resolution makes it a poor tool for diagnosing cavities.

Lateral Cephalometric

  • It is a radiograph of the profile of a patient.
  • Commonly used by orthodontists to evaluate the dental and skeletal relationship of upper and lower teeth and jaws. For example, patients with severe overjet, also known as overbite, this X-ray will help the orthodontist to diagnose if the problem is the prominent upper jaw or a weak lower jaw. The cause will significantly affect the treatment approach.

Disadvantage

  • Images of the different structures and the opposite side may overlap each other.
  • Image and the actual profile may not be exactly the same size.  
  • Only represents one side of the face.
  • Two dimensional

Cone Beam Computed Tomography (CBCT)

As mentioned above, the main disadvantage with the previous X-rays being that a 2 dimensional image is representing a 3 dimensional structure. CBCT on the other hand provides a 3 dimensional representation which makes it one of the best tools for precise diagnosis and treatment planning. 

  • All of the structures are the actual size and there is no magnification.
  • There is no overlapping of the image.
  • It provides valuable detailed information about the position of the impacted tooth within the bone and to detect if the adjacent teeth are damaged by it. It can also be used as a communication tool between the orthodontist and oral surgeon in terms of treatment planning for surgical orthodontics.
  • Implant dentistry has been revolutionized by the details that CBCT can provide about the density of the bone and where to place the implant.

Disadvantage

  • More expensive than regular X-rays.
  • More radiation

Computed aided surgical simulation

Fairly new approach that uses the data from CBCT to virtually treatment plan the surgical orthodontic cases. This approach provides the most comprehensive treatment planning that is available today. We would like you to know that we are one of a few offices in the nation that utilizes this technique.

We look forward to being a part of your wonderful, life-changing experience.
