Histological and Histomorphometric Effectiveness of the Barrier Membranes for Jawbone Regeneration: An Overview of More Than 30 Years’ Experience of Research Results of the Italian Implant Retrieval Center (1988–2020)

Abstract

With the advent of implant dentistry, height and width of the bone site are fundamental to perform implant placements. There are several techniques to restore the amount of bone loss and one of them is guided bone regeneration, which is based on the employment of a membrane in order to bypass non-osteogenic cell invasion in the bone healing area, dispersing every interference with bone regeneration. Two expert reviewers performed a retrospective evaluation of all scientific papers published by the Implant Retrieval Center Laboratory of University “G. D’Annunzio” of Chieti-Pescara in the last three decades, and they implemented it by also similar conducting research on the main scientific databases, i.e., PubMed, Scopus, and EMBASE. The search was conducted up to December 2020, and a total of 843 articles published by the Implant Retrieval Center Laboratory of University “G.D’Annunzio” of Chieti-Pescara were identified and evaluated. After the application of inclusion and exclusion criteria, a total of 27 manuscripts were included for the qualitative synthesis: 8 animal studies, 17 human studies, and 2 in vitro articles. The present overview shows the importance of translational research for barrier membranes for bone regeneration, and additionally, the need for experts in different fields and research centers to produce high quality data in future research.
