Tenting Screws Versus Autogenous Ring Block Grafts During Horizontal Ridge Augmentation

Egypt20 participantsStarted 2025-03-10

Plain-language 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. 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

Inclusion Criteria: * Patient has anterior maxillary horizontal defect less than 4mm in the alveolar ridge and (classified as class III or IV atrophy according to Cawood and Howell classification). (Cawood \& Howell, 1988require horizontal bone augmentation in anterior maxilla before dental implant placement and in need of an implant-supported restoration in at least one site, * Adult individuals aged 18 years or older * Satisfactory oral hygiene, * No previous history of bone augmentation procedures at the site to be treated in the study, * The ability to comprehend and provide informed consent. Exclusion Criteria: * Uncontrolled systemic disorders, * Prior irradiation in the head and neck region, * Immunosuppression or compromised immune system, * Oral disorders such as lichen planus, ongoing or recent treatment with intravenous amino- bisphosphonates, untreated periodontitis, * Poor oral hygiene and motivation, * Parafunctional habits, pregnancy or lactation, * Substance abuse involving drugs or alcohol, psychiatric disorders, a history (within the last 3 months) of regular use of smokeless chewing tobacco, smoking a pipe, cigar, or more than 10 cigarettes per day, acute or chronic infection or inflammation in the area, or * Extraction with less than 3 months of healing.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
