Class II Malocclusion Correction Using Twin Block Appliance: A Literature Review
Class II malocclusion is one of the most common orthodontic problems and occurs in almost one third of the population. Its characteristics are in the form of retrognatic mandible and large overjet, resulting in an imbalance in the soft tissue profile. Treatment that can be done depends on various factors that influence the condition of the malocclusion, one of which is to consider the age status of the patient's growth. Twin block appliance is one of the most common types of functional appliance used in class II malocclusion cases because of its ability to produce rapid changes.. The study aimed to review the role of twin block appliance as a type of functional appliance that can be a treatment option for correcting Class II malocclusions. Scientific evidence and clinical cases are drawn from the literature to support this review and information about the role of twin block appliance in correcting class II malocclusion. The effectiveness of treatment results in the use of twin blocks in correcting Class II malocclusion must be supported by patient compliance in their use.
