Use Ultrasound To Regrow Teeth And Bone - A Broken Tooth Can Be Re-Grown
In One Year
June 29th 2006
Researchers from the University of Alberta believe they have found a
method of regrowing teeth and possibly bone that have been broken. The
scientists use a miniaturized low-intensity pulsed ultrasound (LIPUS)
system-on-a-chip which offers a non-invasive and novel way to stimulate
jaw growth and dental tissue healing.
Dr. Tarak El-Bialy from the Faculty of Medicine and Dentistry and Dr.
Jie Chen and Dr. Ying Tsui from the Faculty of Engineering developed a
tiny wireless ultrasound transducer device that comfortably fits inside
the patient’s mouth while packed in biocompatible materials. The device
is mounted on an orthodontic or “braces” bracket or even a plastic
removable crown. The team also designed an energy sensor that will
ensure the LIPUS power is reaching the target area of the teeth roots
within the bone.
