Microscopic Apical Surgery And Autogenous Dental Bone Powder Filling

After the bone window is made in the microscopic root apex surgery, the self-demineralized autologous dental bone powder is filled into the bone window. This medical record shows that after extracting the patients own teeth and treating them through desensitization and disinfection, Autogenous bone powder was made. It was then filled into the bone window after apical surgery. The postoperative healing was good without infection . 1) After the extraction of teeth 18 and 24, they were processed into autologous tooth bone powder, turning "waste into treasure," providing a new approach and method for successful bone grafting and reducing the patient's financial burden. 2) Microscopic apical surgery, following the "gold standard" of Professor Kim's apical surgery, strictly adheres to surgical standards. Three months post-surgery, X-rays show the reconstruction of trabecular bone. 3) No adverse reactions were observed after the implantation of autologous tooth bone powder, and postoperative X-rays indicate good osteogenesis. 4) Microscopic apical surgery was performed according to the surgical concepts and standards of Professor Kim. The application of converting extracted teeth into bone powder avoids the trauma and pain associated with bone harvesting and allows for "waste utilization." Autologous teeth contain low-crystalline hydroxyapatite minerals similar to human bone tissue, facilitating good bone remodeling through osteoconduction. Decalcified dentinal tubules can better transmit nutrients to osteoblasts, and dentin and cementum contain many growth factors, such as Type I collagen and BMP (bone morphogenetic protein), which play a significant role in bone development and regeneration.
