Clinical Trial Summary

The bone grafting materials currently used in dentistry are autografts, allografts, xenografts, and alloplastic grafts. Among these different types of bone graft materials, autografts are considered to have the most predictable results due to its properties of osteogenesis, osteoinduction and osteoconduction. However, bone autografts are rarely used due to the high morbidity associated with harvesting the bone graft from the patient with a second surgical site. Because of the increased risk to the patient with autogenous bone grafts, the current standard of care is an allograft, which is a bone graft harvested from cadaver sources such as Freeze-Dried Bone Allograft (FDBA). While allografts can only possess the qualities of osteoinduction and osteoconduction, they also have dramatically less morbidity due to the lack of a second surgical site. Studies have shown that autogenous dentin grafts promote all three ideal mechanisms for bone regeneration. There are two methods to generate autogenous dentin grafts. One is to collect the extracted tooth and to send it to a tooth bank for the preparation process. The second is to process the extracted tooth in a clinical setting chairside, for a graft. A dentin graft can undergo different treatments such as demineralization, mineralization, and partial-demineralization. Although the autogenous dentin graft has shown positive results for bone regeneration, the comparison between partial-demineralized, mineralized autogenous dentin grafts, and freeze-dried bone grafts in the clinical setting for immediate grafting has not been studied in humans. Thus, there is a need to study the benefits of autogenous dentin partial-demineralized and mineralized grafts versus freeze-dried bone allografts regarding clinical, radiographically (bone volume and density), and efficacy results. This research addresses these areas of need.

This research addresses these areas of need. A. Specific Aims Specific Aim 1: Is there a clinical-radiographical difference in terms of bone volume and density between mineralized dentin grafts, partial demineralized tooth grafts, and FDBA? Null Hypothesis (Ho): Experimental groups (Mineralized, and partial demineralized dentin grafts) do not have positive changes in terms of bone volume and density when compared to FDBA Alternative Hypothesis (H1): Experimental groups (Mineralized, and partial demineralized dentin grafts) show better results in terms of bone volume and density when compared to FDBA. Secondary Aim: Evaluate if there is any difference in terms of efficacy among partial-demineralized dentin graft, mineralized dentin graft and FDBA.
