Vertical GBR by using heterologous bone block and non resorbable membrane

The lack of mechanical stimuli, periodontal disease, trauma and neoplasms involve resorption both vertically and horizontally of the bone base. In the rehabilitation of the stomatognathic system, three-dimensional restoration of the bone bases is required.
With restoration procedures on implants, this need has become even more pressing. Valid and long-lasting results are obtained with bone regeneration (GBR), as evidenced by the literature.
Currently, possible uses for the stabilization and isolation of the graft concern harvesting intra- and extra-oral, homologous and/or heterologous grafts or a mix between the two, the use of grids or non-resorbable membranes. This case report deals with a type of graft of equine origin, made antigen-free by means of enzymes at 37°C, preserving the collagen matrix, in combination with a GBR technique.
Purpose
The purpose of this paper is to evaluate whether, by using a biomaterial of heterologous origin (equine) in blocks in conjunction with a non-resorbable membrane, one is able to achieve optimal vertical regeneration, in order to place implants of adequate diameter and height, without having recourse to intra-oral or extra-oral harvesting. Finally, the regenerated volume and primary implant stability will be evaluated.
