This study aims to clinically and digitally evaluate immediate implants placed in mandibular molar extraction sockets and compare the outcomes of xenograft, e-PRF, and no grafting material within the jumping gap.
Following atraumatic extraction and implant site preparation within the interradicular bone, the implant will be immediately inserted. A chairside customized healing abutment will then be fabricated to seal the extraction socket. According to group allocation, the jumping gap will be filled with xenograft, e-PRF, or left unfilled before placement of the customized healing abutment. Definitive prosthetic restoration will be delivered after three months of implant insertion. 1. Clinical Evaluation: Implant stability will be assessed at implant placement and at 3 and 6 months using resonance frequency analysis with the Osstell device, with implant stability quotient (ISQ) values recorded. Peri-implant soft-tissue health will be assessed using the modified sulcus bleeding index (mSBI) at 3 and 6 months intervals. 2. Digital Evaluation: Peri-implant soft-tissue dimensional changes will be assessed using intraoral optical scans obtained preoperatively and at 1, 3, and 6 months. The resulting STL files will be superimposed using a best-fit alignment algorithm to evaluate dimensional changes in the peri-implant soft tissues. 3. Radiographic Evaluation: CBCT examinations will be obtained preoperatively, immediately after implant placement, and at 6 months. Three-dimensional superimposition of baseline and follow-up DICOM datasets will be used to evaluate hard-tissue dimensional changes.

after tooth extraction and implant placement, xenograft particulates were placed to fill the jumping gap before sealing the socket with a chairside socket sealing abutment.
after tooth extraction and implant placement, e-PRF was prepared from the patient's collected blood and placed to fill the jumping gap before sealing the socket with a chairside socket sealing abutment.
