简要总结
In conventional segmental sandwich osteotomy technique the moving the transport segment inferiorly to increase the vertical height causes the segment to move bucco-palatally, increasing the horizontal defect. So using the computer guided in segmental sandwich osteotomy and fixation the transport segment hopefully will reduce the bucco-palatal tipping.

研究组 & 干预措施
computer guided sandwich osteotomy
segmental sandwich osteotomy will be done for vertically deficient ridges in anterior area of the maxilla. Either using surgical guides (Computer guide segmental sandwich osteotomy technique) for study group and conventional segmental sandwich osteotomy technique for control group.
干预措施: computer guided sandwich osteotomy (Procedure)
conventional sandwich osteotomy
:conventional segmental sandwich osteotomy will be done for vertically deficient ridges in anterior area of the maxilla.
