Classification of Malocclusion

Topic of my presentation was Classification of Malocclusion. In Orthodontics it is very essential to diagnose the deformity in order to proceed for treatment. Therefore to diagnose malocclusion different authors have given their system of classifications. Angle was the first one to differentiate malocclusion into Class I, Class II and Class III. His system was based on maxillary first molar. This system is widely but has various disadvantages. This system does not consider malocclusion in vertical and transverse plane and cannot be applied if first molar is absent.  . In order to overcome these disadvantages, many authors came up with new methods of classification. Dewey’s modified angle’s Class I into 5 types and Angle’s Class III into 3 types. Other classifications are canine and premolar classification which are used when molar is missing. Lischer’s classified Angles malocclusion into neutroocclusion, disto occlusion and mesioocclusion. He classified tooth positions into mesioversion , distoversion , labioversion , linguoversion . Simon’s classification includes Frankfort horizontal plane, orbital plane and median saggital plane.  The most advanced system of classification was given by Ackermann Profit . The uniqueness of this system is that it classifies malocclusion in all 3 planes saggital, transverse and vertical. Finally the deciduous dentition classification was given by Baume. He considered flush terminal plane, mesial step and distal step. Thus the lecture was a complete guide to various system of malocclusions used in Orthodontics.
