Horizontal Ridge DeficiencyNCT06845449
Tenting Screws Versus Autogenous Ring Block Grafts During Horizontal Ridge Augmentation
A study testing tenting screw combined with particulate autogenous and autogenous ring block grafts combined with xenogenic bone in people with Horizontal Ridge Deficiency, run by Fayoum University at 1 site in Egypt.
Trial summary
After administering local anesthesia,. A full-thickness mucoperiosteal flap will be incised and be reflected to expose the alveolar bone. The dimensions of the defect will be measured using a periodontal probe to determine the appropriate size of the block graft or the quantity of particle bone graft required.

About this study
Official title: Tenting Screws Combined With Particulate Autogenous and Xenogenic Bone Versus Autogenous Ring Block Grafts Combined With Xenogenic Bone During Horizontal Ridge Augmentation
After administering local anesthesia,. A full-thickness mucoperiosteal flap will be incised and be reflected to expose the alveolar bone. The dimensions of the defect will be measured using a periodontal probe to determine the appropriate size of the block graft or the quantity of particle bone graft required.
In the non screw group, the blocks will be adapted to fit the recipient sites and secured to the alveolar bone using titanium bone fixation screws. Following the placement of the blocks, bovine particles will be applied over the graft and into any remaining gaps between the block and the recipient site, a resorbable collagen membrane (CM) will be shaped and placed over the graft and fixed using subperiosteal sutures.

In Tenting screw cases, the screws will be placed in suitable positions and depths, blocks will be crushed into particulates which will then be mixed with equal amount of bovine particles. the mixture will be applied to the recipient site all around the tenting screws a resorbable collagen membrane (CM) will be shaped and placed over the graft and fixed using subperiosteal sutures.
The flaps will then be sutured

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
After administering local anesthesia,. A full-thickness mucoperiosteal flap will be incised and be reflected to expose the alveolar bone. The dimensions of the defect will be measured using a periodontal probe to determine the appropriate size of the block graft or the quantity of particle bone graft required.
In the non screw group, the blocks will be adapted to fit the recipient sites and secured to the alveolar bone using titanium bone fixation screws. Following the placement of the blocks, bovine particles will be applied over the graft and into any remaining gaps between the block and the recipient site, a resorbable collagen membrane (CM) will be shaped and placed over the graft and fixed using subperiosteal sutures.

Questions about this trial
What is this clinical trial studying?
A study testing tenting screw combined with particulate autogenous and autogenous ring block grafts combined with xenogenic bone in people with Horizontal Ridge Deficiency, run by Fayoum University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?

The record says: enrolling by invitation, as of the sponsor's last update on 25 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Horizontal bone width gain (time frame: 6months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Mar 2025; AzTrials last refreshed its copy on 26 Oct 2026.
