Impacted Teeth
With CBCT, it has become very easy to determine where an
impacted tooth is located in relation to the rest of the dentition.
Traditionally, many different types of x-rays were needed to
localize an impacted tooth in relation to the adjacent teeth.
Although the films were able to identify whether the tooth was
buccal or lingual, it was still impossible to measure exactly how
far away the impacted crown was to the roots of the other teeth.
With CBCT, the diagnosis becomes a simple visual exercise,
with the images showing exactly the location of the entire
dentition, even the impacted teeth. The inclination of the teeth,
direction of eruption, and completion of rootformation is shown.
The CBCT software can also measure exactly how far in the bone
the impacted tooth is positioned, and can accurately determine
the distance to the closest root structure.
CBCT diagnosis makes the recovery of these teeth much easier
for orthodontists and oral surgeons. Orthodontists use this
extensive information in devising the best biomechanics and
vectors to bring the impacted teeth into the dental arch. Oral
surgeons, knowing exactly where the tooth is located, can
minimize the amount of bone drilling needed to access the crown
of the teeth and avoid damage to adjacent proximal root
structures.
Other applications for CBCT:
· Temporo-mandibular Joint (TMJ)
· Oral Pathology
· Orthodontics
· Periodontics
· Airway Assessment
· Cervical Spine
· Specialized Visualization Technique
nSequence 3D Diagnostic Imaging provides a full range of imaging services to support any implant, oral or maxillofacial surgical treatment planning
needs. We also offer 3D image interpretation and consultation service by an oral and maxillofacial Radiologist.
nSequence is pleased to introduce a new 3-dimensional imaging technology to Reno. The new technology is known as Cone-Beam Computed
Tomography (CBCT) or Cone-Beam Volumetric Tomography (CBVT) and is an x-ray imaging approach that provides high resolution 3-dimensional images
of the jaws and teeth. CBCT images provide invaluable information that is not contained in conventional 2-dimensional films. The quality of CBCT images
is comparable to conventional medical CT scans but at a fraction of the radiation dosage, ensuring that radiation exposure is kept to a minimum.
Cone-Beam CT fulfills a much needed comprehensive diagnostic imaging in dentistry. The technology is derived from its medical counterpart, the
computed axial tomography, which is one of the most important radiological exams world-wide. While cone-beam CT is very different from medical CT, it
also produces 3-dimensional images. Clear advantages of CBCT are its rapid imaging time (under 40 seconds) and its much lower radiation dose
compared to medical CT.

Clinical applications of CBCT imaging
Dental Implants
Dental clinicians who are placing dental implants are rapidly
becoming one of the largest user groups who are referring patients
for CBCT scans and images. This is because CBCT generated
images provide more information not contained in regular 2D films.
Both 2D and 3D X-rays can show bone height and width, yet only the
CBCT can measure the bone thickness of the jaws and also define
the shape of the bony contours. CBCT can also accurately locate the
position of the inferior alveolar canal in the lower jaw, thereby
minimizing the risk of parasthesia caused by damaging the nerve.
In the upper jaw, knowing exactly how much bone there is for the
implant site will reduce perforations through the maxillary sinus.
All of these advantages result in a greater success rate from CBCT
guided implant placement.
