Abstract

HiBi FBG are used to demonstrate a technique to evaluate orthodontic forces. The experiments are performed in an artificial maxilla supporting dental wax and metal teeth. The teeth are instrumented using an orthodontic technique and loads are applied representing auxiliary appliance. The values of the loads (extra-oral) are based on clinical applications. It is demonstrated that the tooth vestibular surface is subject to a force of 0.13 N. The size and sensitivity of the FBG allow for the determination of forces applied orthogonally to the surface of the teeth.
