For many decades, researchers have tried to develop materials that could be used just like autogenous bone. The editors of this book have assembled experts to showcase recent developments in tissue engineering and to demonstrate the basic biologic phenomena of bone repair using dentin grafts, growth factors, stimulating factors, inductive factors, and other factors in clinical applications. The research gathered in this book underscores the excellent outcomes based on sound science and pioneering clinical applications. New techniques using the tooth materials provide realistic and practical regenerative treatments for all patients.
