Single vs. Double Tenting Screws for Horizontal Ridge Augmentation.

The Effect Of Single Versus Double Screws In Tenting Screw Technique For Horizontal Ridge Augmentation Before Dental Implant Placement (Randomized Clinical Trial)

The goal of this clinical trial is to learn if using two screws works better than one screw for building up jawbone width before dental implant placement. It will also check the safety of both techniques. The main questions it aims to answer are:

• Does using two screws give better bone growth than using one screw?
• Which technique creates more stable bone for dental implants?

Researchers will compare the single-screw technique to the double-screw technique to see which works better for jawbone reconstruction.

Participants will:

• Receive either one or two small titanium screws placed in their jawbone to support a bone graft
• Have the graft covered with a protective membrane
• Return after 6 months for screw removal and dental implant placement
• Attend follow-up visits to check healing progress

The study will help dentists determine the best method for patients who need jawbone reconstruction before getting dental implants. All procedures use FDA-approved materials and follow standard surgical protocols.
