Case 1
Case 2
Bite Ramps, Part 2: Class 3 Bite Ramps
A
s I mentioned in my December
column, I don't think there has
been a bigger game-changer in
my offi ce's clinical process in
regard to treatment effi ciency than
strategically positioning and shaping
our bite turbos. [Editor's note: If you
missed Dr. Foster's December column,
which focused on Class 2 bite ramps,
head to orthotown.com/magazine
and click the link embedded inside this
column.]
Here, I'll share a few case examples
and my thoughts on how I approach
Class 3 bite ramps. (I will be presenting
this material with much more
in-depth discussion during a scientifi c
lecture at the general session of the
2023 AAO Annual Session in Chicago,
so if you're attending that meeting, I
hope to see you at my presentation!)
To begin with, Class 3 bite ramps
are not a universal fi x for any and
every Class 3 malocclusion. Th ey do
not produce orthopedic maxillary
advancement and they likely don't
restrain mandibular growth. Th eir
principal anteroposterior (AP) eff ect
acts to advance/mesialize the maxillary
dentition and retract/distalize
the mandibular dentition, to " jump " a
tooth or teeth out of anterior crossbite.
In this manner, in regard to patient
selection, if a patient is not an ideal
candidate for these tooth movements
or if the crossbite is secondary to a
more signifi cant skeletal Class 3 jaw
position, they might not be an ideal
candidate for Class 3 bite ramps. If,
however, the patient in anterior crossbite
is a good candidate for these tooth
movements, I fi nd the occlusal correction
occurs much faster and with less
reliance on patient cooperation.

Th e key to case selection with
Class 3 ramps is simple. Have the
patient fully seat themselves in centric
occlusion. Th en have them slightly
open to the point where the anterior
tooth/teeth crossbite is unlocked
and see if there is a retrusive AP slide
into centric relation that brings the
anterior teeth closer into a more edgeto-edge
position. If this is the case,
and if the upper incisor angulation
aesthetically/functionally allows a
mild increase in labiolingual torque
and the lower incisor angulation also
aesthetically/functionally allows a
mild decrease in labiolingual torque,
then you likely have a great case to
employ this technique.
A few additional tips:
* When bonding the ramp to lower
anterior teeth, make sure you bond
it to multiple teeth for a splinting
