Abstract
Class II malocclusions affect over twenty percent of the population. Over the years numerous appliances have been invented and modified in order to treat this type of maloclussion. Functional appliances have been advocated for their ability to assist in mandibular growth along with restraint of maxillary growth, as two-thirds of Class II malocclusions are classified with retrognathic. Publications from the following electronic databases were searched: PubMed, Web of Science, Cochrane Library and Science Direct. Searches included any article published until July 13, 2012. Searches were performed under the term "ForsusTM." These searches yielded sixty-one (61) articles. These were reviewed for relevance based on inclusion and exclusion criteria. Articles were excluded if they did not measure the effectiveness of ForsusTM treatment or were not written in English. Seven (7) articles were deemed of relevance with a high quality study design and were included in this study for evaluation. The current literature suggests that Class II treatment with the ForsusTM appliance is an effective and efficient method to treat Class II maloclussions in six months. It produces mainly a restraining effect on maxillary growth, while the Class II molar correction is derived primarily from dentoalveolar changes. Overjet and overbite is reduced through proclination, mesialization and intrusion of the mandibular incisors and retrusion and extrusion of the maxillary incisors. There is also a distalizing and intrusive force on the maxillary first molars which make this appliance ideal for high angle and open bite cases. Some other noted effects are palatal and occlusal plane clockwise rotation and slight expansion of the intermolar widths after treatment. The other obvious advantage is the continuous wear guaranteed by this non compliance method of treatment.
