Horizontal Bone Augmentation Using The Sausage Technique: A Case Report

This case report illustrates the application of the “sausage technique” in a patient with severe horizontal bone deficiency, demonstrating successful bone augmentation and optimal primary stability. The “sausage technique” is a bone grafting method that involves tightly packing graft material within a membrane to create maintained osteogenic space. In this case healthy 45-year-old female with a horizontal width of 3.6 mm in posterior mandible was operated. A mucoperiosteal flap was elevated, then autogenous bone was collected using a bone scraper. After perforating the cortical plate, the collagen membrane (25*25mm, Bio-Gide, Geistlich) was fixed at the base with titanium pins. Then the mixture of xenogeneic (0.5g, Bio-Oss, Geistlich) and autogenous bone was placed, and the top of the membrane was immobilized. The ridge demonstrated a horizontal width of more than 8 mm after 8 months of healing, and two implants sized 4.1×10 mm (ITI, Strauman) were placed at the site of #45 and #46. After three months, the crowns were fabricated and cemented. For patients with severe horizontal bone deficiency, the “sausage technique” would be a reliable option. In this case, the ridge presented a horizontal bone gain of ≥4.4 mm after the application of “sausage technique” and implants demonstrated excellent osseointegration, primary stability, and soft tissues integrated. “Sausage technique” employs the tension of biological membranes to establish a stable space for bone formation, facilitating effective bone augmentation.
