size drills and subsequent implants
to use.
CBCT scans can be taken to evaluate
the bone prior to starting the implant.
A 2021 study found CBCT a highly accurate
method4
over 2D radiology for
detecting and measuring peri-implant
bone defects.
Prior to the advent of CBCT, there
was no viable way to clinically evaluate
whether a patient was a good
candidate for dental implants without
actually laying a flap. With CBCT,
dentists can now clinically evaluate if
enough quality bone is present, and
whether the bone is strong enough or
if grafting will be needed to augment
4
the bone. For example, images that
show generalized pitting with thin
borders may point to osteoporotic
changes, indicating poor quality bone
in that area.
A study in the European Journal of
Molecular and Clinical Medicine5
found that " CBCT is advantageous
in evaluating alveolar fenestrations
and dehiscences, which determines
the need for alveolar bone grafting at
the time of implant placement... In
anterior maxilla, CBCT has the main
advantage in measuring alveolar bone
height in the nasal floor region. When
implants are planned in the anterior
maxillary region, CBCT is used, due
to the capability of measuring buccal

alveolar bone width. In the maxillary
premolar and molar region, bone quality
and vertical height in relation to
the maxillary sinus, buccal and lingual
cortical thickness are imaged properly
with CBCT. "
" If you only have a 2D panoramic
image, you can see the height of the
bone but that's about it, " explains Dr.
Vorholt. " You have to flap the tissue
back to feel its thickness. With 3D imaging,
you have a clearer view of the
situation prior to the surgery, so you
can potentially make a smaller incision
and use a less invasive approach. "
Treatment planning CBCT helps the
dentist identify the right implant size,
CASE
Nº
2
A patient was missing
teeth three, four and five.
The CBCT scan revealed
that the patient's sinus
drooped down. The 3D image
provided a much more precise measurement
than a PA radiograph, in
which other structures like the cheekbone
would have been superimposed
on the image. With CBCT, it was clear
exactly where the sinus was and
which technique was appropriate for
the sinus lift. In this case, Dr. Vorholt
was able to perform the less invasive
version of a sinus lift.
The second premolar also needed a
procedure to add more bone. The
insights from the CBCT scan helped
Dr. Vorholt prep the patient appropriately,
so they understood the costs
and the time that would be involved
to heal. Because Dr. Vorholt knew
preoperatively the type of surgery
necessary, he prescribed Augmentin
to help the sinus stay as healthy as
possible during and immediately after
surgery. The patient healed nicely
from the surgery, and was pleased
with the final result.
Top and bottom images: Preoperative treatment planning using CBCT allows the surgeon to
choose the appropriate approach to implant placement. This includes whether sinus augmentation
is necessary and what approach is taken. The patient can be better prepared, the team
can be better and appropriately compensated and the surgery can be performed with better
ease and accuracy.
