Horizontal ridge augmentation is a common surgical procedure performed prior to or simultaneously with implant placement, depending on the extent of the ridge deficiency. Many horizontal augmentation surgical options have been developed, spanning a wide range of materials and techniques. Given the numerous permutations available, the most suitable strategy to regenerate ridge width for an individual case often confounds clinicians. Based on an extensive review of the literature, this article provides up-to-date technique selection guidelines, in the form of a decision tree, for predictable horizontal bone augmentation dependent on the amount of bone gain needed.
