Vertical Bone Gain and Neurosensory Affection in Computer Guided vs Conventional Sandwich Osteotomy

Future University in Egypt7 enrolled

Overview

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.

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.

sandwich interpositional bone grafting computer guidedPROCEDURE

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

conventional interpositional bone graftingPROCEDURE

performing the conventional interpositional sandwich osteotomies free-hand and fixation of the mobilized bone segment free-hand
