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