INITIATION OF PROCESS STANDARDIZATION TO FABRICATE DEMINERALIZED BONE DIRECTED TOWARDS MAKING MATERIALS FOR BONE GRAFTING
Main Article Content
Abstract
Background: Bone tissue, a vital component for self-healing. This inherent regenerative capacity enables bones to repair themselves following injury or damage. Understanding the mechanisms behind bone tissue self-healing is of great significance in the field of medical research and has implications for the development of novel therapeutic approaches. In this article, we explore the fundamental characteristics and mechanisms underlying the self-healing properties of bone tissue. In certain instances of trauma or pathological conditions resulting in bone defects, the natural healing process may be insufficient. Consequently, the implementation of bone transplant interventions becomes imperative for successful bone regeneration. The predominant origins of bone grafts encompass autologous, homologous, and heterologous sources. The allograft, a widely utilized bone grafting technique, has gained significant popularity, and is currently in high demand within the medical field. The current state of allograft utilization in our nation has proven insufficient in meeting the demands of patients. Henceforth, a method has been devised and standardized for the procurement of demineralized osseous tissue, a crucial investigation in light of the insufficiency of allografts in meeting the requirements of patients. Objectives: Initially, standardizing an efficient procedure to obtain demineralized bone sources from human skull fragments from three different inclusion methods. Materials and Methods: Using three different types of solutions to obtain demineralized bone from human skull tissue including solutions of Formic Acid (10%), Hydrochloric Acid (5%), a mixture of solution: Formic Acid (10%) - Acid Hydrochloric (5%) (ratio 1:1,v/v). Demineralized bones were evaluated by comparing the mineral content extracted from bone samples, demineralization time, and analysis of ions concentration in bone samples (including Ca and P) before and after demineralization. Besides, demineralized bones were histologically stained before and after demineralization to assess the bone structure. Results: The Ca and P extraction rates of this method are high and standard, about 98% and 93%, respectively. The demineralization process only takes about five days. Relative bone tissue retains most of the structure of compact bone tissue. Conclusion: The procedure that our team has established is the right one for obtaining demineralized bone as bone replacement material and applies to a wide variety of human bone tissue.
