Clinical and Radiographic Evaluation of CGF and Alloplastic Grafting in Participants Undergoing the Socket Shield Technique for Immediate Anterior Maxillary Implant Placement. This Study Assesses Bone Healing and Stability When Managing the Crestal Gap in the Esthetic Zone.

This prospective case series investigates the synergistic effect of Concentrated Growth Factor (CGF) and alloplastic bone substitutes within the Socket Shield Technique. The primary clinical challenge addressed is the "jumping distance" or crestal gap that naturally forms between an implant and the extraction socket wall. While SST is designed to prevent the resorption of the buccal bundle bone by retaining a root fragment, this study explores whether the biological enhancement of CGF can further optimize the regenerative environment .Technical Procedure and Biological Rationale The surgical protocol utilizes a Partial Extraction Therapy approach where the tooth crown is decapitated and the root is sectioned mesiodistally. A labial shield is maintained to provide structural support to the labial bone plate. Following a standard osteotomy, the "sticky bone" complex is prepared .The Concentrated Growth Factor (CGF) is produced using a specialized centrifuge with a variable spin-speed protocol, which results in a denser fibrin network compared to first or second-generation platelet concentrates. This matrix allows for the sustained release of essential signaling molecules to promote osteogenesis and soft tissue regeneration. Regenerative Synergy The intervention combines the biological activity of the autologous CGF with the osteoconductive properties of an alloplastic graft. While the alloplastic material provides a stable, predictable scaffold to maintain space and volume within the jumping gap, the CGF accelerates the early stages of healing and bone formation. This combination is hypothesized to provide superior mechanical and biological properties for long-term stability in the esthetic zone .Clinical Monitoring Following immediate temporization, participants enter a strict plaque control regimen. Longitudinal evaluation is performed using limited-field Cone-Beam Computed Tomography (CBCT) to quantify changes in bone volume and integration. These scans are conducted at specific intervals to monitor the transition from early healing to the final bone remodeling phase prior to definitive prosthetic loading.
