随着口腔医学的发展,种植牙已成为牙缺失修复治疗的最佳选择之一,然而由于拔牙后牙槽骨发生不可逆的生理改建过程,造成的骨量不足常为种植医师带来困扰。许多学者通过改进手术方法或利用各种生物材料减少或限制牙槽骨吸收(即牙槽窝保存术),从而获得理想的美学和功能修复。本文就牙槽窝保存技术、微创拔牙、骨移植材料和屏障膜的使用等进行综述。 With the development of stomatology, dental implants have become one of the best choices in the treatment of tooth loss. However, due to the irreversible physiological remodeling of alveolar bone after tooth extraction, the lack of bone mass is often troublesome to the implantologist. Many scholars achieve ideal aesthetic and functional repair by improving surgical procedures or using a variety of biological materials to reduce or limit alveolar bone resorption (ie, alveolar preservation). This article reviews the preservation of dental socket, minimally invasive extraction, the use of bone graft materials and barrier membranes.
