Brief 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.

Study Arms (3)

Freeze-Dried Bone Allograft Control

OTHER

-Control group (FDBA): extracted teeth will be discarded and sites will be grafted with FDBA.

Procedure: Freeze-Dried Bone Allograft control

Mineralized Dentin Graft

EXPERIMENTAL

-Test group I (mineralized tooth graft): extracted teeth will undergo the mineralization process according to the manufacture's guidelines. Procedure will be done in a specialized equipment for tooth graft preparation (Smart Dentin Grinder® (SDG) (KometaBio), and then sites will be grafted. Remaining graft will be stored appropriately for future grafting in the same patient (according to the guidelines)

Procedure: Mineralized Dentin Graft

Partial-Demineralized Dentin Graft

EXPERIMENTAL

-Test group II (partial-demineralized tooth graft): extracted teeth will be undergone to partial-demineralized process, according to the manufacture's guidelines. Procedures will be done in a specialized equipment for tooth graft preparation (Smart Dentin Grinder® (SDG) (KometaBio), and then sites will be grafted. Remaining graft will be stored appropriately for future grafting in the same patient (according to the guidelines).

Data Sharing

IPD Sharing
Will share

It is estimated that individual patient date will be shared to a very limited number of individuals to help with facilitating the statistical analysis of the study, as well as writing up the Master Thesis and future publications. Also, upon request, it is required to share study related information to our internal Institutional Review Board.

Shared Documents
STUDY PROTOCOL, SAP, ICF, CSR, ANALYTIC CODE
Time Frame
The estimated time frame for sharing data would be approximately until May 2025
Access Criteria
Institutional Review Board officials, Master Thesis Chair and Committee members, and statisticians, will be able to review data. Also, Dr. John Corbett, will be performing a followup study and possibly extending the time frame for Dr. Perozo's study measurement. It is also anticipated, but not actual, that future studies be performed for longitudinal analysis.
