In plain words

What the trial is, and whether it could suit you

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 .

📋 Eligibility rules (as published)
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.
