Ridge Preservation Following Tooth Extraction

Plain-language summary

An animal study and our pilot human study demonstrated that placing a smooth-surface titanium bone screw (TBS) over the buccal plate of an extraction socket resulted in less dimensional changes of the alveolar ridge along with no adverse effects. The purpose of this randomized clinical trial is to investigate the effectiveness of TBS application for ridge preservation in comparison to (1) unassisted/non-interventional socket healing and (2) alveolar ridge preservation (ARP) approach using allografts and a membrane.

Inclusion Criteria: * age ≥18 years * a tooth, which is in the area from the central incisor to the second premolar bounded by teeth (or implants) mesiodistally * a tooth requiring extraction Exclusion Criteria: * thyroid dysfunctions * diabetes mellitus * history of a chronic use of corticosteroids (\>6 months) * history of oral/intravenous bisphosphonates within the past 2 years * smoking * history of other systemic conditions that could affect bone integrity.

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.
