A Double Layers Technique for Maxillary Sinus Augmentation with Demineralized and Mineralized Bone Graft Materials

Abstract

The maxillary posterior edentulous region presents unique and challenging conditions in implant dentistry. The height of the posterior maxilla is reduced greatly as a result of dual resorption from the crest of the ridge and pneumatization of the maxillary sinus after the loss of teeth. Materials previously used for sinus floor grafting include autogenous bone, allogeneic bone, xenogenic bone and alloplastic materials. Autogenous bone is the material of choice, but its use is limited by donor-site morbidity, complications, sparse availability, uncontrolled resorption and marked volume loss. One way to overcome this problem would be to use bone substitutes alone as a osteoconductive scaffold for bone regeneration from the residual bone or in combination with allogeneic bone, which also has osteoinductive properties. The purpose of this article is to describe a double layers technique of demineralized and mineralized bone graft materials instead of autogenous bone in sinus floor augmentation of deficient posterior maxillary alveolar process and to report our experience with this technique. Our results show that maxillary sinus augmentation using mineralized and demineralized bone materials, when installed simultaneously with the implant or not, is good results for bone healing.
