An alternative method of
augmenting a narrow ridge is by ridge splitting instead of only grafting. This
technique can be applied in selected cases. It requires that the alveolar ridge
has two cortical plates separated by a layer of chancellor’s bone in a
preoperative CBCT image. This situation is normally confined to alveolar ridges
featuring an orofacial thickness of more than 4mm.
Ridge
splitting can be performed simultaneously with implant placement. This is the
only way to obtain primary stability in this scenario is by engaging the bone at
the apical region of the implant. In
selected cases, it may be possible to stabilize the mobilized buckle plate with
bone screws if required.
It
is advisable to perform the splitting with minimal flap reflection to expose
only the Cristal region of the ridge. A somewhat higher level of surgical skill
and experience is needed for flapless ridge splitting compared to conventional
bone grafting.
The
main indication for ridge splitting is to expand a horizontally reduced ridge
in the maxilla and take advantage of elastic and chancellors quality of this
bone and its peripheral type of blood perfusion.
Splitting
a narrow mandibular ridge is possible but technically more difficult due to
brittle, thicker, and more cortical nature of this bone.
A
flapless approach in the maxilla offers the benefits that even small bone
fragments remain attached to periosteum and are contained by the intact
soft-tissue envelope. On balance, ridge expansion via splitting is effective
but does have its limitations.
Only
bone grafting, with addition to particulated grafts and a membrane for
protection, is the more versatile and widely used approach.
