Abstract

BackgroundThis study aimed to evaluate the clinical usefulness of autogenous fresh demineralized tooth (auto-FDT) graft prepared at the chairside for alveolar bone grafting during dental implant surgery.MethodsIn total, 38 patients requiring both tooth extraction (for endodontic or periodontal reasons or third molar extraction) and alveolar bone regeneration for dental implant placement were included. Within 2 h after clean extraction, the teeth were prepared at the chairside to serve as bone graft material. In the same sitting, blocks or chips of this graft material were used to reconstruct defects at the osteotomy site simultaneously with or before implant placement. Twelve months after prosthesis fabrication and placement, the clinical findings and implant success rates were evaluated. Histological studies were randomly conducted for selected cases.ResultsClinical evaluation showed favorable wound healing with minimal complications and good bone support for the implants. No implant was lost after 12 months of function following prosthetic rehabilitation. Histological examination revealed new bone formation induced by the graft material.ConclusionsChairside preparation of autogenous fresh demineralized teeth after extraction can be a useful alternative to the use of autogenous bone or other graft materials for the immediate reconstruction of alveolar bone defects to facilitate subsequent implant placement.

Highlights

This study aimed to evaluate the clinical usefulness of autogenous fresh demineralized tooth graft prepared at the chairside for alveolar bone grafting during dental implant surgery
Xenogenic, and alloplastic graft materials have been used as alternatives, but they have a number of drawbacks compared with autologous grafts, such as decreased function, the potential risk of infectious disease, an unsatisfactory resorption pattern, a prolonged healing time, and high cost [1]
The defects at the osteotomy site requiring implant placement were restored with graft material prepared using the teeth from the original extraction sites (n = 30) or third molars (n = 8)

Summary

Introduction

This study aimed to evaluate the clinical usefulness of autogenous fresh demineralized tooth (auto-FDT) graft prepared at the chairside for alveolar bone grafting during dental implant surgery. Type I collagen, have attracted attention because of their ability to improve the cellular responses of osteogenic lineages, ensuring better bone regeneration [2]. The tooth is increasingly attracting attention as a material for alveolar bone regeneration. It is composed of an organic matrix and an inorganic reinforcing phase of hydroxyapatite. The inorganic content is 70%–75%, organic content 20%, and water content 10%. In alveolar bone, these components are present in proportions of 65%, 25%, and 10%, respectively [6]. Tooth has much lower fat content and no marrow
