简要总结
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.

研究组 & 干预措施
Single tenting screw
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
干预措施: horizontal bone augmentation using single tenting screw (Procedure)
Double tenting screw
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.
干预措施: horizontal bone augmentation using Double tenting screw (Procedure)
结局指标
主要结局
Change in Horizontal Ridge Width at Mid-Crestal Level
时间窗: 6 months post-intervention
Ridge width will be measured at the mid-crestal level using a bone caliper to the nearest millimeter. A standardized stent will ensure consistent measurement positioning.
Change in Horizontal Ridge Width 5 mm Apical to Crest
时间窗: 6 months post-intervention
Ridge width will be measured 5 mm apical to the crestal level using a bone caliper to the nearest millimeter. The same stent will standardize measurements.
次要结局
- Change in Keratinized Mucosa Width at 6 Months Post-Reentry(6 months post-intervention)
- Change in Alveolar Ridge Width via CBCT at 6 Months(6 months post-intervention)
- Change in Bone Density via CBCT at 6 Months(6 months post-intervention)
