CBCT use in dental practices
CBCT systems can record different
fields of view, depending on the application.
A small field of view shows
several teeth in higher resolution. This
is typically used for endodontics when
visualizing root fractures, periapical
lesions or root canal issues. A medium
field of view typically shows the maxilla
and mandible. This is often used to
image one or both dental arches for
Real-world examples
Dr. Vorholt shares real cases
that illustrate the value
of 3D imaging for practices.
CASE
Nº
1
During a screening that
included CBCT review,
Dr. Vorholt discovered
the contralateral maxillary
molar had an asymptomatic apical
infection, likely due to a vertical root
fracture. The patient was referred
back to their original dentist, who
extracted and grafted the site, and
an implant was later placed and
restored. The 3D images made it
clear exactly where the undercut of
the patient's mandible was, so that
he could perform the implant surgery
without damaging the mandible or
surrounding nerves.
Top right image: While planning an
implant for tooth number 30 in the CBCT,
measurements of the width of bone and
height to the mylohyoid ridge undercut
were taken to ensure appropriately sized
implants were placed and to avoid potential
anatomical complications. Coincidentally,
while planning for implants in the patient's
lower right, the upper left first molar was
noted to have a large, asymptomatic vertical
root fracture. The clarity of the infection
and severity of it on the CBCT scan versus
the 2D image helped convince the patient
of the importance of treatment, even
though she was asymptomatic. She was
advised to return to her general dentist for
evaluation. That dentist removed the tooth
and grafted the site for a future implant.
implant planning. A large field of view
includes the mandibular condyles and
may also show airway space. This may
be used by oral surgeons or orthodontists,
depending on the specific case.
Unlike conventional 2D radiographs,
CBCT offers the ability to see some
soft tissues and bone, as well as
nerve pathways, all in one view. This
is particularly beneficial for implant
dentistry.
The role of CBCT in implant treatment
planning and placement
Diagnostic considerations An accurate
assessment of bone quality and
quantity is crucial for determining the
viability of implant surgery. This helps
dentists identify whether patients are
suitable for implant surgery and what
areas are ideal for implant placement.
Knowing the quality of the bone helps
determine where to drill and what
Bottom left and bottom right images: CBCT leads to more thorough diagnosis and treatment
and can pick up unrelated pathology. This is beneficial for the dental team for improving
production, as well as advantageous for the patients, because issues are often identified
before they cause pain. In this instance, the extent of the hard tissue damage and scope
of the infection around tooth number 14 is not as clear in a PA of the same region versus
the CBCT. After extracting and grafting the site, an implant was later placed and restored to
maintain the patient's occlusion and archform.
