“…Resorbable membranes show better results in comparison to non-resorbable ones regarding compatibility with soft tissues and lower rates of exposure and complications [4]. However, due to the chemical cross-linking process of different types of membranes, interference in their enzymatic degradation may occur, leading to prolonged biodegradation [9]. This can affect the GBR, mainly when vertical bone defects are involved since a prolonged degradation time of the membrane is needed so that the bone substitute can undergo angiogenesis and initiate the bone tissue neoformation.…”

“…In this clinical case, this property was achieved due to the type of membrane used, which was a porcine pericardium one. In fact, this membrane is highly resistant to rupture and has a high degree of biocompatibility and prolonged resorption time due to the collagen structure in multiple layers, which in turn helps in the angiogenesis process [9,10].…”

Background: The placement of implants in the posterior mandible with the vertical bone defect can be associated with inadequate crown height space. Therefore, the vertical bone reconstruction of these defects is often necessary, although this procedure is technically challenging. Methods: A 49-year-old patient attended a private dental office for rehabilitation of an atrophic posterior mandible. The clinical and tomographic findings show absence of teeth #36, #37, #46, #47, and #48 with severe atrophy. Vertical bone augmentation was performed by using the guided bone regeneration technique with pericardium resorbable membrane followed by placement of short implants. The free gingival graft was performed, and after three months, screw-retained lithium disilicate single ceramic crowns were manufactured. Results: After a 3-years follow-up, bone loss around the implants or presence of gingival inflammation was not observed, and the prosthesis adaptation was found to have no alteration either. Therefore, aesthetics, as well as masticatory and speech functions, were preserved. Conclusion: There was no bone loss around the implants. The association between vertically guided bone regeneration using pericardium resorbable membrane is an alternative technique, and it avoids complications related to non-resorbable membrane exposure. It was shown to be viable after a 3-year follow-up.
