hey guys welcome back to the channel today we're going to be looking at angle's classification of milo occlusion edward h angle classified malocclusion using the relationship between the first molars of both arches as a key factor in determining occlusion the three classes according to angle's classification are as follows you have the normal occlusion which is where the mesobuccal cusp of the upper first molars occlude with the buccal groove of the lower first molar the class one male occlusion is same as a normal occlusion but characterized by crowding rotations and other positional irregularities number two class two male occlusion this is where the mesobuccal cusp of the upper first molar occludes anterior to the buccal groove of the lower first molar and these can be separated into two subtypes so you can get a class two tip one this is where the upper insides are tilted outwards or protruded and creating a significant object so if you can remember that the over jet is remember a jet will travel in a horizontal distance so the overjet is the horizontal distance between the upper and the lower central incisors the class 2 div 2 relationship is where the upper incisors are retroclined so this will cause an increased overbite so this is going to be a vertical relationship between the upper and the lower central incisors the class iii male occlusion this is where the mesobuccal cusp of the upper first molar occludes posterior to the buccal groove of the lower first molar well thank you very much for listening i hope this video helped you in your understanding of the angles classification please kind of like and subscribe to our channel i will bring you more videos for you in the future thank you bye
