Whether the anchorage concept produces the desired tooth movement is determined by the way the teeth respond. Serviceability limit state Load Case C, with dead loads only and partial factors of unity, is used to determine the serviceability limit However, the practical applications of FRP are limited by the tendency of FRP materials to fail suddenly under lateral pressure and surface injury.
