Socket preservation maintains bone volume post-extraction in anticipation of an implant placement or fixed partial denture pontic site. This procedure helps compensate for the resorption of the facial bone wall. Socket preservation should be considered when implant placement needs to be delayed for patient or site-related reasons. The ideal healing time before implant placement is six months. Socket preservation can reduce the need for later bone augmentation. By reducing bone resorption and accelerating bone formation it increases implant success and survival. Biomaterials for socket grafting including autograft, allograft, xenograft and alloplast. A bone substitute with a low substitution rate is recommended.
牙槽窝保存术在拔牙后维持骨量，为后续种植体植入或固定局部义齿桥体部位做准备。该手术有助于补偿颊侧骨壁的吸收。当因患者或部位相关原因需要延迟种植体植入时，应考虑牙槽窝保存术。种植体植入前的理想愈合时间为六个月。牙槽窝保存术可减少后期骨增量的需求。通过减少骨吸收和加速骨形成，它提高了种植体的成功率和存留率。用于牙槽窝植骨的生物材料包括自体骨、同种异体骨、异种骨和人工合成骨。建议使用替代率低的骨替代材料。
