Horizontal onlay by using heterologous bone block and resorbable pericardium membrane in conjunction with a major sinus lift.

Bone regeneration procedures make it possible to restore deficiencies in virtually all atrophic areas. Implant positioning to re-establish the masticatory load is thus made easier, with no functional and aesthetic impairments. The research of grafting biomaterials able top osteointegrate, maintain bone volume and reduce the many complications due to using autologous bone (gold standard) has steered regenerative surgery towards grafts that are conducive to excellent regeneration, so as to support proper implant positioning.
in this case report, a sinus lift and a horizontal maxillary onlay were performed by grafting collagen material of equine origin, made antigen-free with multi-enzyme treatment.
Purpose
The purpose of this paper was to position implants in a prosthetically guided manner, performing bone regeneration with heterologous material only: a sinus lift and a horizontal onlay. It was decided to graft a material of equine origin, made antigen-free by means of enzymes and to use a covering pericardium membrane, in order to evaluate inserting the implant in an appropriately regenerated bone area, without having recourse to intra- and extraoral harvesting.
