Dental implant therapy often requires bone augmentation to facilitate stable implantation with a predictable outcome. Traditionally, this is accomplished through guided bone regeneration (GBR), which is a series of surgical procedures that use barrier membrane technology to direct the growth of new hard and soft tissues in sites with insufficient volumes for the purpose of placing dental implants. GBR and implant placement can be performed in either one or two surgeries. This article will focus on a novel simultaneous approach that utilizes a custom milled cancellous allograft bone ring that is stabilized through the graft preparation and apical threads of the dental implant. Indications include simultaneous implant placement in a deficient sinus as well as horizontal and vertical four-, three-, two-, and one-wall defects.
牙种植治疗通常需要进行骨增量，以促进稳定种植并获得可预测的结果。传统上，这是通过引导骨再生（GBR）来实现的，GBR是一系列外科手术，利用屏障膜技术引导新的硬组织和软组织在骨量不足的部位生长，以便植入牙种植体。GBR和种植体植入可以在一次或两次手术中进行。本文将重点介绍一种新颖的同期方法，该方法使用定制铣削的松质骨同种异体骨环，通过种植体的植骨准备和根尖螺纹实现稳定。适应症包括在骨量不足的上颌窦同期植入种植体，以及水平和垂直的四壁、三壁、两壁和单壁骨缺损。
