Abstract: Anterior segmental osteotomy (ASO) is considered the
treatment modality of choice in patients with bimaxillary
dentoalveolar protrusion. However, this meticulous surgical technique
accompanies a number of possible disadvantages. The considerable
time required before, during, and after the operation,
limited movement of the segment, damage of the mental nerve,
loss of tooth vitality, loss of a tooth or teeth, or indeed total loss of
the anterior segments are those that affect the result of the surgery.
Recently, the authors have devised a computer-aided surgical
simulation programme and fabricated the customized osteotomy
guides and the spider-shaped plates based on the programme. They
were then applied to a 28-year-old patient with the complaint of a
bimaxillary dentoalveolar protrusion. This approach helped to
overcome several problems related to ASO reported earlier.
