One-stage Versus Two-stage Inverted U-shaped Ridge Splitting

Not Applicable

Completed

• Conditions: Maxillary Ridge Augmentation

• Registration Number: NCT04720495
• Lead Sponsor: Hams Hamed Abdelrahman

Brief Summary

Fourteen patients having anterior maxillary undercut defect were selected to match a list of inclusion and exclusion criteria.

The participants were randomly allocated using a computer system into two groups:

Group A undergo inverted U-shaped maxillary ridge splitting using piezotomes with simultaneous implant placement in the same surgery.

Group B undergo inverted U-shaped maxillary ridge splitting as a first stage and after four weeks, ridge expansion and implant placement will be performed with only envelop flap.

Assessment included measurements of bone gain at the undercut defect and bone density labial to implants in each group from the cone-beam computed tomography
