简要总结
The aim of this study was to assess the efficiency of the computer-guided interpositional sandwich osteotomy for the vertical bone gain and effects on vital structures (inferior dental nerve bundle) compared to free hand interpositional osteotomies.
详细描述
in this research a full digital sandwich osteotomy protocol was conducted to be compared with the conventional protocol. the investigators were seeking to determine the significance of using surgical computer software in sandwich interpositional bone grafting at atrophied posterior mandibles and how efficiently can it affect this technique.

研究组 & 干预措施
computer guided sandwich interpositional bone grafting
patient specific cutting guide were fabricated to perform the osteotomies ( and another patient specific guide was then fabricated to start the fixation of the cut bony segment a full digital intervention for sandwich interpositional grafting in patients with vertically atrophied mandible (bilateral split mouth study)
干预措施: sandwich interpositional bone grafting computer guided (Procedure)
conventional sandwich osteotomy interpositional bone grafting
conventional interpositional bone grafting was done for patients with vertically atrophied mandibles (bilateral split mouth study)
干预措施: conventional interpositional bone grafting (Procedure)
结局指标
主要结局
