After tooth extraction, a physiological process of alveolar bone resorption begins. The

surrounding soft tissues also undergo changes. The replacement of the lost tooth by

means of implants can be difficult or even prevented by the lack of hard tissue for

anchoring and stability of the implant. The lack of soft tissue impairs the aesthetic

result and longevity of the work due to loss of protection of the implant/prosthetic part

transition zone. For these reasons, research seeks to investigate the use of

allogeneic and/or xenogeneic materials to preserve bone structure after tooth

extraction through selective repopulation of cells and tissues. The objective of this

study was to systematically review the literature in search of randomized clinical trials

carried out in humans who underwent tooth extraction associated or not with tissue

regeneration for alveolar preservation with a view to rehabilitation with

osseointegrated implants. The scientific literature was surveyed and 597 studies

were found in Pubmed, Web of Science, Embase, Scopus, Cochrane and Lilacs/BBO

databases. After removal of duplicates, analysis process and final selection of

studies, 10 randomized controlled trials were included in the qualitative analysis. The

results indicate that sockets treated with bone graft with allogeneic/xenogeneic

material present greater reduction of the bone defect after extraction than sockets in

spontaneous healing. This review encourages the performance of alveolar

regeneration procedures to optimize rehabilitation through dental implants. The

protocol of this systematic review was registered in PROSPERO (CRD42021248413)

and followed the PRISMA recommendation rules (Key Items for Reporting

Systematic Reviews and Meta-analyses).
