Brief summary
Immediate implant placement in the esthetic zone is often associated with buccal bone deficiency, which may compromise esthetic outcomes and long-term implant stability. Autogenous bone graft harvested from the maxillary tuberosity provides corticocancellous bone with favorable biological properties and may help reconstruct the buccal bone plate during immediate implant placement. This prospective case series aims to evaluate the clinical and esthetic outcomes of immediate implant placement combined with autogenous maxillary tuberosity graft in the esthetic zone. The primary outcomes include buccal bone thickness measured on cone-beam computed tomography (CBCT), facial soft tissue thickness measured clinically, and the pink esthetic score (PES) after implant restoration.
Detailed description
Immediate implant placement has become a widely accepted treatment modality in the esthetic zone. However, the presence of buccal bone defects following tooth extraction may negatively affect peri-implant tissue stability and esthetic outcomes. Autogenous bone graft harvested from the maxillary tuberosity has been proposed as a reliable grafting material due to its corticocancellous structure and high osteogenic potential. This prospective interventional case series aims to evaluate the effectiveness of autogenous maxillary tuberosity graft used in conjunction with immediate implant placement in the esthetic zone. Patients requiring extraction and implant placement in the maxillary esthetic region will be treated with immediate implant placement and augmentation using a two-layer autogenous graft harvested from the maxillary tuberosity, consisting of cortical bone and connective tissue. Clinical and radiographic outcomes will be assessed during follow-up. Buccal bone thickness will be evaluated using cone-beam computed tomography (CBCT). Facial soft tissue thickness will be measured clinically. Esthetic outcomes will be assessed using the pink esthetic score (PES) following definitive prosthetic restoration. The results of this study are expected to provide clinical evidence regarding the effectiveness of maxillary tuberosity autogenous grafts for improving peri-implant tissue stability and esthetic outcomes in immediate implant placement.
Interventions
PROCEDUREImmediate Implant Placement With Maxillary Tuberosity Autogenous Graft
Immediate implant placement in the maxillary esthetic zone combined with autogenous bone graft harvested from the maxillary tuberosity. The graft is used to reconstruct the buccal bone plate and improve peri-implant tissue stability and esthetic outcomes.
