Vertical Ridge Augmentation (VRA): Success and Predictability

Purpose of Review The purpose of the present review was to discuss the success and predictability of vertical ridge augmentation (VRA) with the use of guided bone regeneration (GBR). Recent Findings Weighted mean gains in vertical heights of 8.04 mm (distraction osteogenesis), 4.18 mm (GBR), and 3.46 mm (block grafts) were reported for the specific VRA procedures; however, a superior technique was not identified. Summary VRA with GBR is a technique-sensitive procedure with the potential of regenerating significant heights of vital bone, which should be performed by highly experienced clinicians due to the potential for severe complications. Regardless of the technique used for VRA, two important factors for a successful and predictable outcome are (i) the defect morphology and (ii) the proper flap management/advancement to obtain and retain a tension-free primary closure.
