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

Not Applicable

Completed

• Conditions: Bone Loss
• Interventions: Procedure: conventional interpositional bone grafting; Procedure: sandwich interpositional bone grafting computer guided

• Registration Number: NCT05666414
• Lead Sponsor: Future University in Egypt

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.
