Abstract
Several techniques have been proposed to increase the mandibular bone base, both horizontally and vertically, for implant purposes in atrophic distal ridges. Block graft and titanium grids are frequently used for this purpose. The former need to be fixed, in the case of an autologous bone block require a donor site graft, and if not kept sufficiently vascularized could result in necrosis. The latter are manageable with difficulties in the event of exposure and are removed with difficulty. In this work a technique is proposed which makes use of resorbable cortical lamina in order to create recipient sites which can be filled with prehydrated and collagenated granules covered by mesenchymal resorbable membranes. We demonstrated with this technique the good vascularization of the graft combined with the integration of the lamina, which do not need to be removed. Our results allow us to propose this technique as a potential alternative to those used to date.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
