What this Trial Is About
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 .

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Medically healthy patients classified as ASA I or ASA II
- Age greater than 18 years
- Presence of 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 or palatal bone to achieve primary implant stability
You will not qualify if you...
- Patients classified as ASA III, ASA IV, or ASA V
- Vertical root fracture involving the labial aspect of the root planned to be retained as the facial shield
- Horizontal root fracture located too far apically
- Presence of acute (active) periapical infection
- Large chronic periapical lesion
- Insufficient bone apical to the extraction socket to achieve primary stability
- Ankylosed tooth positioned too apically relative to adjacent teeth
