L-PRF Versus Sticky Bone Grafting of the Jumping Gap in AI-assisted Computer-Guided Socket Shield Immediate Implantation
Egypt45 participantsStarted 2026-02-23
Plain-language summary
the rationale of the current study is to address a focused and clinically relevant gap in socket shield therapy: which biologic modality best supports healing of the shield-implant gap when SST is performed under a standardized, digitally guided workflow. The study will compare three shield-implant gap filling modalities: (i) L-PRF alone (without membrane), (ii) sticky tooth (autogenous dentin graft +i- PRF), and (iii) sticky bone (particulate graft + i- PRF) under AI-assisted, patient-specific guided implant placement based on IOS/CBCT superimposition, with CBCT follow-up at immediate, 3 months, and 6 months. The working hypothesis is that biologically active, cohesive composites (sticky tooth and sticky bone) will provide superior hard- and soft-tissue dimensional stability compared with PRF alone by improving space maintenance and early wound stability in the shield-implant gap . The null hypothesis is that there will be no statistically significant differences between the three modalities in radiographic and digitally assessed clinical outcomes over the 6-month follow-up period .

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Medically healthy patients according to the American Society of Anesthesiologists (ASA) physical status classification system; only patients belonging to ASA I and ASA II categories will be included in this study.
* Age \> 18 years.
* Patients presenting with one non-restorable hopeless anterior tooth due to extensive caries, cervical/root fracture, vertical or oblique root fracture, multiple failed endodontic treatments, or root resorption.
* Sufficient apical/palatal bone to obtain primary implant stability.
Exclusion Criteria:
* Patients belonging to ASA III, ASA IV and ASA V will be excluded.
* Vertical root fracture involving the labial aspect of the root planned to be retained as the facial shield.
* Horizontal root fracture that is too far apically located.
* Presence of acute (active) periapical infection.
* Large chronic periapical lesion.
* Lack of sufficient bone apical to the extraction socket to obtain primary stability. \* Ankylosed tooth positioned too apically in relation to adjacent teeth.
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?

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.
