Many edentulous posterior maxillas are found to be
encumbered by alveolar ridge resorption and increased pneumatization
of the sinus. These factors limit the quantity and quality of bone
necessary for successful implant placement in these areas. One
solution is the use of shorter implants but this often results in an
unfavorable crown to root ratio. In order to create an improved
environment in such small regions, the classical sinus floor elevation
with bone augmentation is a well-accepted technique. However, when the
edentulous area is limited to a zone between one or two teeth, lifting
the membrane becomes difficult and may be subject to iatrogenic
injury. The Antral Membrane Balloon Elevation (AMBE) technique is a
modification and combination of surgical techniques that add
sufficient bone height allowing placement of longer implants of up to
16mm. The success of this technique does not depend on the accessible
ridge height and when teeth are adjacent to the edentulous area, the
membrane is easily elevated making the antral floor accessible for
augmentation with the appropriate graft material.
