P1-ORTHO-PPT 1

branch of dentistry concerned with facial growth, development of the dentition and occlusion and the diagnosis, interception and treatment of occlusal anomalies

Orthodontics

what is the primary goal of orthodonic treatmennt

improve the 1. appearance, 2. function and 3. overall health of the patient's smile

define occlusion in orthodontics

the anatomical alignment of the teeth and their relationship to the rest of the masticatory system

define ideal occlusion

optimum anatomical position of teeth

define malocclusion

dental anomalies that deviates from the ideal occlusion

what was anngle's most noteworthy appliances?

E-arch (1900)

Pin and Tube (1910)

ribbon Arch (1915)

Edgewise appliance (1928)

first typical orthodontic fixed appliance

E-arch (1900)

appliance the is theoretically capable of great precision but impractical in clinical use

pin-and-tube (1910)

the first appliance to use a true bracket

ribbon arch (1915)

appliance not popular due to poor control of mesiodistal tipping

ribbon arch (1915)

most well known and commonly used orthodontic appliance

edgewise appliance (1928)

size of edgewise appliance

0.022 x 0.028 slot oriented horizontally

angle's postulate

the upper first molars are the key to occlusion

corners of the occlusion

canines

describe the line of occlusion in the maxillary arch

smooth curve passing through he central fossa of each upper molar and across the cingulum of the upper canines and incisors

describe the line of occlusion in the mandibular arch

same line runs along the buccal cusps and incisal edges of the lower teeth

serves as secondary guidance for when there is absence of molar relationship

canine relationship

molar and canine relationship of class I (neutrocclusion)

mesiobuccal cusp of maxillary first molar occludes with the mesiobuccal groove of the mandibular first molar

maxillary canine lies between the mandibular canine and first premolar

class II molar and cannine relationship (distocclusion/retrognathism)

mesiobuccal cusp of the maxillary first molar is mesial to the mesiobuccal groove of the mandibular first molar

maxillary canine is mesial to the mandibular canine

class III molar and canine relationship (mesiocclusion/prognathism)

mesiobuccal cusp of the maxillary first molar is distal to the mesiobuccal groove of the mandibular first molar

maxillary canine is distal to the mandibular canine

class I type 1

class I molar relationship with anterior crowding

class I type 2

class I molar relationship with labioversion of the maxillary central incisors

class I type 3

class I molar relationship with anterior crossbite

class I type 4

class I molar relationship with posterior crossbite

class I type 5

class I molar relationship with mesial drifting of first molars

class II division 1

class II molar relationship with maxillary centrals in extreme labioversion

class II division 2

class II molar relationship with maxillary centrals tipped palatally and maxillary laterals tipped labially

class III type 1

class III molar relationship with edge to edge bite

class III type 2

class III molar relationship with anterior crowding

class III type 3

class III molar relationship with anterior crossbite
