Vertical bone augmentation with guided bone regeneration. A scoping review

Introduction: There are multiple techniques for vertical bone augmen-tation. Guided regeneration is one of them; however, the literature diverse and includes different study designs, which makes it difficult to synthesize results. Objective: To analyze general technical characteristics, clinical results, complications augmentation performed with guided in humans. Material Methods: This scoping review was based on PRISMA-ScR guidelines. A search Pubmed, Scielo, Worldcat databases. Papers published from 1990 April 2020 were included study. Research articles not conducted humans or languages other than English Spanish excluded. Title abstract screened by two reviewers, then full studies extracted, data tabulated. Results: 89 included. The highest percentage reported having obtained a increase less 5 mm used non-resorbable membranes. most frequent type graft autogenous combinations grafts, common being xenograft. All that stability implants regenerated favorable, as implant survival, reporting values between 83.8% 100%. Membrane exposure frequently complication, followed infection abscesses, tissue dehiscence. Conclusion: Vertical reliable technique, high predictability low incidence compared techniques.
