Bone Loss
Conditions
Brief summary
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.
Detailed description
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.
Interventions
performing the 2 vertical and the 1 horizontal osteotomies using a cutting patient specific guide and fixation of the vertically elevated bony segment after gap calculation using patient specific fixation guides
performing the conventional interpositional sandwich osteotomies free-hand and fixation of the mobilized bone segment free-hand
