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.
