Treatment of non-compliant skeletal class II malocclusion with a hybrid appliance – A case report and review literature

Abstract

The present case describes a case of skeletal deep bite class II malocclusion treated efficiently using the Forsus appliance, and its importance of clinical and biomechanical considerations. Skeletal deep bite class II malocclusions with deficient mandible are treated with different functional appliances. There are several appliances for its correction in a growing child. However, fixed functional appliances are commonly used in the present clinical scenario for those non-compliant cases, who present late with less residual growth or no growth. This case was treated with a pre-adjusted edgewise appliance supplemented with a device known as Forsus Fatigue Resistant Device (FFRD) (3M Unitek Corp, California, USA). FFRD is a good alternative device for skeletal deep bite class II malocclusions instead of class II elastics in mild cases and place of Herbst appliance in severe cases. Biomechanical principles should be considered for those patients with the Forsus appliance to prevent complications. There are fewer complaints from the patients and treatment time is less.
