Abstract
Following tooth extraction, the alveolar bone goes through a natural remodeling process resulting in a significant bone resorption which may complicate dental implant placement without prior bone augmentation treatment. The sausage technique is a modified guided bone regeneration (GBR) method that has been successfully used for horizontal bone augmentation. This technique was developed to increase the bone growth at the alveolar crest. Although the sausage technique uses a combination of autograft chips and xenograft particles with a native collagen membrane, several studies have questioned whether adding autograft chips is essential for bone formation with guided bone regeneration. Moreover, harvesting the bone graft may increase the donor site morbidity and patient discomfort. This case report aimed to investigate the bone gain radiologically when the sausage technique was applied to treat a healthy, thirty-year-old patient with a horizontal defect in the posterior mandibular region using anorganic bovine bone mineral (ABBM) particles with Jason membrane, assess the implant primary stability in the augmented ridge, and present the surgical procedure steps in details. After nine months of healing, the cone-beam computed tomography (CBCT) revealed approximately 4.32 mm of bone gain at the alveolar crest in the buccal-lingual direction. The graft particles were well integrated into the newly formed bone. Two implants were inserted with an insertion torque of 35 N/cm. The ISQ values were 76 for the most anterior implant and 78 for the posterior implant. Within the limitations of this case report, the sausage technique using ABBM particles without autograft chips was an effective approach in achieving the prerequisite bone width at the crest in cases with horizontal bone defects.
