Summary

This trial will compare the effects of autogenous dentin partial-demineralized and mineralized grafts versus freeze-dried bone allografts on bone regeneration.

Who is the study for?
This trial is for adults over 18 with teeth needing extraction and intact alveolar sockets. Participants must understand and agree to the study's requirements. It excludes pregnant or lactating women, those with active gum disease, root-filled or infected teeth, heavy smokers, uncontrolled diseases, past head/neck radiation therapy, or bisphosphonate use.Check my eligibility
What is being tested?
The study compares three bone graft materials in dental surgery: Mineralized Dentin Graft (MDG), Partial-Demineralized Dentin Graft (PDDG), and Freeze-Dried Bone Allograft (FDBA). The goal is to see which material best promotes bone regeneration clinically and on X-rays.See study design
What are the potential side effects?
Potential side effects may include discomfort at the graft site, swelling, infection risk increase due to surgery, allergic reactions to graft materials if any existent allergies are unknown prior to treatment.

Trial Design

3Treatment groups
Experimental Treatment
Group I: Partial-Demineralized Dentin GraftExperimental Treatment1 Intervention
-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).
Group II: Mineralized Dentin GraftExperimental Treatment1 Intervention
-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)
Group III: Freeze-Dried Bone Allograft ControlExperimental Treatment1 Intervention
-Control group (FDBA): extracted teeth will be discarded and sites will be grafted with FDBA.

Mechanism Of Action

Prior Approvals
Other Research
The most common treatments for alveolar bone loss, such as autogenous dentin grafts, work through three primary mechanisms: osteogenesis, osteoinduction, and osteoconduction. Osteogenesis involves the formation of new bone by osteoblasts present in the graft material. Osteoinduction is the process by which the graft material induces the differentiation of progenitor cells into osteoblasts, promoting new bone formation. Osteoconduction provides a scaffold that supports the growth of new bone along its surface. These mechanisms are crucial for patients with alveolar bone loss as they collectively enhance bone regeneration, improve structural integrity, and support the stability of dental implants or natural teeth.
