Change in Mandibular Bone Width Using Two Stages Splitting Approach

Not Applicable

Completed

• Conditions: Narrow Mandibular Ridge
• Interventions: Procedure: 2-stage ridge splitting

• Registration Number: NCT04589806
• Lead Sponsor: Hams Hamed Abdelrahman

Brief Summary

Alveolar ridge splitting technique is a commonly used procedure for horizontal ridge augmentation of narrow ridges to allow placement of implants. However, the commonly used one-stage technique can cause malfracture and subsequent necrosis of the fractured part.

Detailed Description

Twelve patients were selected randomly having posterior mandibular narrow edentulous ridge. The sample were selected to match a list of inclusion and exclusion criteria. In the first stage, all patients will underwent a mandibular ridge splitting technique using piezotomes. In the second stage, ridge expansion and implants were placed with only envelope flap. Assessment were included measurement of the buccal and lingual bone surrounding the implants and amount of increase in the bone width from the cone beam computed tomography.
