ABSTRACT

Numerous techniques have been proposed to increase bone volume before implant insertion. Initially, non-resorbable biomaterials allowed a ‘curtain effect’ capable of isolating the site to be regenerated and preventing it from being invaded by epithelial cells were used. However, titanium-reinforced membranes allow excellent dimensional stability but require a second removal procedure and are difficult to manage in case of dehiscence. Here, a technique that uses a curved heterologous cortical lamina to cover a bone defect between two peaks is reported. The curved bone plate creates a containment space filled with pre-hydrated and collagenated granules. They will be subsequently reabsorbed and transformed into bone. The excellent vascularization of the graft combined with the integration of the lamina (which must not be removed) allows us to propose this technique as a potential alternative to those used so far.
