Peri-implant Tissue Changes Using Dual Zone Concept with Connective Tissue Graft Versus Concentrated Growth Factor

Tooth extraction not only alters the bony architecture of the alveolar ridge, but it also has an impact on the surrounding soft tissues. Post-extraction recovery of both hard and soft tissues occurs uneventfully, resulting in horizontal and vertical tissue loss, affecting prosthetic rehabilitation with dental implants or tooth-supported prosthesis. Aim of the study: The aim of this study is to evaluate volumetric soft tissue alterations as well as clinical, radiographic, and esthetic outcomes in dual zone technique (DZ) using CTG (Connective Tissue Graft) versus CGF (Concentrated Growth Factor) Graft following maxillary IIP (Immediate Implant Placement) in the esthetic zone. Materials and methods: 20 patients with hopeless teeth requiring extraction in maxillary esthetic zone and requiring replacement with dental implants, will be enrolled and recruited from the outpatient clinic, faculty of dentistry, Ain Shams University according to the inclusion criteria. They will be randomly allocated into two equal groups. Group I (n=17) immediate implant placement with dual zone technique using concentrated growth factor graft and group II (n=17) immediate implant placement with dual zone technique using connective tissue graft. Pink esthetic score (PES) was measured 6 months after the final crown placement. At the respective times radiographic CBCT measurements, volumetric analysis, and clinical measurements will be taken. Postoperative medication will be prescribed to the patient and postoperative instructions will be explained in detail. Follow-up will be performed. Data collected will be tabulated and statistically analyzed.
