Functional appliance:. The aim of the inclined planes of the bite blocks in twin block is to modify these inclined planes and cause more favorable growth pattern.

Functional appliances by altering the position of the teeth and supporting tissues, establish a new and more optimal functional behavioral pattern which leads to adaptive changes in the bone form and helps the dentofacial complex achieve, its optimal genetic growth potential. Twin block appliances are simple bite blocks designed for full time wear that achieve rapid functional correction of malocclusion by the transmission of favourable occlusal forces to occlusal inclined planes that cover the posterior teeth. The goal in developing the twin block technique was to maximize the growth response to functional mandibular protrusion by using an appliance that is simple, comfortable and esthetically acceptable to the patient. Occlusal inclined plane :-According to Clarks the occlusal inclined planes were the fundamental functional mechanism for the natural dentition. And the inclined planes play an important role in determining relationship of the teeth as they erupt. If the mandible inclined planes are in a distal relation to that of maxilla then the force acting on the mandibular teeth will have a distal force vector leading to a class II growth tendency.

Mandibular defiiency in a Class II malocclusion is a frequently encountered condition that can be managed with myofunctional appliance in a growing child. An year-old patient presented with a complaint of forwardly placed upper front teeth. The patient had a convex facial profie, acute naso-labial angle, deep mento-labial sulcus with lip trap. Clinically the patient showed positive VTO. CVMIshowed that the patient was in his growth phase. The treatment was done with a standard twin block appliance for 9 months followed by fied orthodontic treatment. The post functional phase showed correction of skeletal class II jaw base and marked improvement in the facial profie from convex to straight. It was later followed by fixed orthodontic treatment in the second phase upon completion of which bonded lin Oscar Mario Antelo. BackgroundThe purpose of this study was to prospectively assess the dentoskeletal effect of a modified Twin Block appliance for treatment of class II malocclusions.
