摘　　要：缺牙区牙槽嵴的重度骨缺损,对于以修复为导向的种植治疗造成了很大的困难。虽然目前有多种可靠的牙槽嵴骨增量技术,但是都存在一定的局限性,如技术敏感性高、创伤大,或治疗周期长、费用高等问题。本病例患者上、下颌牙列缺损,其左下后牙区为重度水平型骨缺损。利用其智齿行自体牙本质块移植,术后2年半获得了令人满意的牙槽骨宽度,植入5 mm直径种植体,牙槽骨密度较高,种植体稳定性良好,术中取标本做组织学观察,未见异常,正式修复后1年,边缘骨稳定。在本病例中,应用自体牙本质块行骨增量手术有效地恢复了牙槽嵴宽度,术后近4年的临床结果稳定。Severe bone defects in the alveolar ridge of edentulous areas pose significant challenges for prosthetically-driven implant placement.Although there are currently several reliable techniques for alveolar ridge augmentation,they present certain limitations,such as high technical sensitivity,significant trauma,prolonged treatment periods,and high costs.The patient in this case presented with multiple missing teeth in both the upper and lower jaws,with a severe horizontal bone defect in the left lower posterior area.Autogenous dentin block augmentation was performed using her wisdom tooth.Two and a half years postoperatively,satisfactory alveolar bone width was achieved,allowing for the placement of a 5 mm diameter implant in dense alveolar bone with good primary stability.Intraoperative histological analysis of tissue specimens showed no abnormalities.One year after the final restoration,marginal bone stability was maintained.In this case,the application of autogenous dentin blocks for alveolar ridge augmentation effectively reconstructed the width of the alveolar ridge,with stable clinical outcomes observed nearly 4 years postoperatively.
