Effects of fixed twin-block and forsus fatigue resistance device on mandibular third molar angulation- a comparative study

Abstract

Introduction: Fixed Functional Appliances such as Fixed Twin Block and Forsus Fatigue Resistant Device improve Class II skeletal relationships by increasing the length of the mandible, which subsequently lead to an increase in the retromolar space. This would bring about a positional and angular change in the mandibular third molar. These appliances also produce forward movement of the mandibular buccal segments, which has also been cited as an important factor providing space and therefore improving the angulation and eruption potential of the third molars
