Not Applicable

Not yet recruiting

• Conditions: Horizontal Bone Augmentation; Horizontal Ridge Deficiency
• Interventions: Procedure: free hand modified ridge splitting technique in horizontal bone deficiency in posterior mandible; Procedure: computer guided modified ridge splitting technique in horizontal bone deficiency in posterior mandible

• Registration Number: NCT06195761
• Lead Sponsor: Cairo University

Brief Summary

To assess the accuracy of the computer assessed guides in horizontal bone augmentation achieved at posterior mandible using guided modified ridge splitting technique versus free hand modified ridge splitting technique

Detailed Description

The first treatment plan includes harvesting and fixing the bone graft in posterior mandibular area using a computer-modified surgical guide.

The second treatment plan includes manually harvesting and fixing the bone graft in posterior mandibular area without a surgical guide.
