About

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.

16 participants in 2 patient groups

Single tenting screw

Experimental group

Description:

8 patients indicated for lateral ridge augmentation in premolar-molar area (class I Seibert's classification) will be candidates to screw tent technique using single screw at crest position

Treatment:

Procedure: horizontal bone augmentation using single tenting screw

Double tenting screw

Active Comparator group

Description:

8 patients indicated for lateral ridge augmentation in premolar-molar area (class I Seibert's classification) will be candidates to screw tent technique using double screws, one at a crestal position and the other one 5 mm apical to the first one.

Treatment:

Procedure: horizontal bone augmentation using Double tenting screw
