TREATMENT OF A BONE DEFECT CONSEQUENT TO THE REMOVAL OF A PERIAPICAL CYST WITH EQUINE BONE AND EQUINE MEMBRANES: CLINICAL AND HISTOLOGICAL OUTCOME

The use of equine enzymatically deantigenated bone substitutes and membranes in bone cysts management

The objective of this study was the clinical and histological assessment of equine bone granules, equine collagen membrane and equine pericardium membrane in bone cyst management. Enzymatically deantigenated equine bone and an equine collagen membrane were used to restore a bone defect caused by the removal of a bone cyst in the upper anterior maxilla. After 4.5 months, an implant was placed and a bone core sample was obtained from the grafted site. Implants threads, though, were exposed. This defect was grafted with a mixture of autogenous and equine bone and covered with an equine pericardium membrane. The deantigenated equine bone is biocompatible and undergoes osteoclastic remodelling. Both the equine collagen and pericardium membrane acted as effective barriers for guided bone regeneration.
