Dermatoglypgic study of normal occlusion and malocclusion
Answers
YOUR ANSWER IS HERE :-
Explanation:
CLASSIFICATION OF NORMAL OCCLUSION AND MALOCCLUSION.
1. ORTHODONTICSORTHODONTICS
2. CLASSIFICATION OF NORMAL OCCLUSION AND MALOCCLUSION.
3. Angle’s described – • Normal occlusion • Three types of malocclusion :- •Angle’s class I malocclusion • Angle’s class II malocclusion - division 1 and division 2 • Angle’s class III malocclusion
4. ANGLE’S CLASSIFICATION OF NORMAL OCCLUSION Mesiobuccal cusp of upper first permanent molar occludes into the buccal developmental groove of the lower first permanent molar. The teeth were arranged on a smoothly curving line of occlusion.
5. First permanent molar relation
6. BSI – Class I Canine - Class I Molar - Class I
7. The line of occlusion - is a smooth ( catenary) curve passing through the central fossa of each upper molar and across the cingulum of the upper canine and incisor teeth. -The same line runs along the buccal cusps and incisal edges of the lower teeth , thus specifying the occlusal as well as interarch relationshiop once the molar position is established.
8. Line of occlusion
9. ANGLE’S CLASSIFICATION OF MALOCCLUSION. CLASS I MALOCCLUSION. Mesiobuccal cusp of upper first permanent molar occludes into the buccal developmental groove of the lower first permanent molar. Line of occlusion is incorrect. There may be crowding, spacings, rotated teeth, supernumerary tooth etc.
10. Missing teeth with spacing Missing teeth with spacing
11. Peg shaped laterals Supernumerary teeth
Answer:
Dermatoglyphics is the study on edpidermal ridges on the palmar and plantar surfaces of the feet and hand. Embryological development of orodental structures and these dermal patterns occur during the same period. ... The finger and palmar prints were obtained and they were analyzed for each type of patterns.
