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.
