Orthodontics — Key differences for NEET MDS
Class I = normal molar relationship crowding anterior. Class II Division 1 = proclined upper incisors overjet increased. Class II Division 2 = retroclined upper incisors deep bite. Class III = mesial lower molar anterior crossbite prognathism. Key is UPPER FIRST MOLAR to LOWER FIRST MOLAR relationship. Dewey-Anderson modification of Class I.

Headgear = extraoral anchorage cervical pull or high pull. Critical anchorage = ALL space needed for crowding. Maximum anchorage = most space for retraction. Moderate anchorage = reciprocal movement acceptable.
