Review of Allogeneic Dentin Graft for Maxillofacial Bone Defects

Abstract

Although autogenous demineralized dentin matrix (auto-DDM) has shown promising clinical and histological results, it has certain limitations beyond its osteoinductivity and osteoconductivity. Therefore, the application of dentin graft material from other individuals-allogeneic DDM (allo-DDM)-has been considered an alternative to auto-DDM. However, few studies have investigated the osteoinductivity and antigenicity of allo-DDM. Herein, we reviewed all human studies related to allogeneic dentin application for the management of maxillofacial bone defects. Clinical studies have shown the osteoinductivity of allo-DDM in extraskeletal and skeletal sites, regardless of occasional antigenicity. Impact statement Although autogenous demineralized dentin matrix (auto-DDM) has shown promising clinical and histological results, it has certain limitations beyond its proven osteoinductivity and osteoconductivity. Therefore, the application of dentin graft material from other individuals-allogeneic DDM (allo-DDM)-has been considered as an alternative to auto-DDM. However, few studies have investigated the osteoinductivity and antigenicity of allo-DDM. This is the first review of all human studies related to allogeneic dentin grafts for the management of maxillofacial bone defects. Clinical studies have shown the osteoinductivity of allo-DDM in extraskeletal and skeletal sites, regardless of occasional antigenicity.
