a: neutroclusion (CL I)
b. distoclusion (CL II)
c. mesioclusion (CL III)
a
Tooth position can be classified as following: mesio-version disto-version labio/bucco-version linguo-version infra-version supra-version torso-version trans-version
mesio : more mesial distal : more distal labio: more toward cheek or lip linguo: toward tongue infra : more toward into bone or less erupted supra : more erupted torso: rotated axis trans: wrong order
Term used to describe wrong place tooth eruption
ectopic eruption
Term describes a conditions present from a birth
congenital
Term describes more number of teeth than normal
supernumerary

Characteristics of preventive orthodontics
- preserve normal developing occlusion
- correction of caries condition
- elimination of had habits
- space maintaining for missing teeth
characteristics of corrective orthodontics
- reduce / eliminate malocclusion
2. intral/extraoral appliance
Following are the tooth movement forces : Rotation Translation Tipping Intrusion Extrusion Torque
rotation: tooth movement around axis
translation: tooth body movement
tipping: tooth upright direction
intrusion: into the bone
extrusion: above bone
torque: root movement without crown movement
