chapter 15 Flashcards
pertains to ‘straight teeth’
orthodontia
term used to describe a “state of not closing well”
Malocclusion
more than the normal amount of teeth in the mouth
hyperodontia
anterior and posterior dental occlusion is normal, or mesial and distal occlusion is normal, but individual teeth are not aligned
Class I: Neutroclusion or neutral occlusion
anterior and posterior teeth alignment is abnormal, causing the maxilla (upper jaw) to protrude more forward than the mandible (lower jaw)
Class II: Distoclusion
anterior and posterior teeth are aligned abnormally, causing the lower jaw (mandible) to protrude further forward than the maxilla
Class III: Mesioclusion
posterior (back) teeth occlude, but the anterior (front) teeth do not
Open bite
upper dentition projects further forward than the mandibular dentition.
Horizontal overlap Commonly called ‘overjet’
lower dentition projects further forward than the maxillary dentition
Underjet
abnormal superior-inferior alignment and occlusion of a tooth with its opposing tooth. May involve one or more teeth.
Crossbite Also called reverse articulation
edges of maxillary and mandidular incisors meet each other
End to End
the goal is to maintain current dental and occlusion integrity and preventing the development of abnormalities.
Preventative orthodontics
exercises are individualized to each patient, to ensure that the muscles are ‘trained’ to perform at their optimum
myotherapeutic (myo-therapeut-ic) exercises
this method is aimed at limiting the extent of an existing concern related to abnormal growth patterns, to prevent further problems.
Interceptive orthodontics
removable appliances that are designed to ensure aligned occlusion
biteplate or a bite guard
intervening with the application of appliances that alter the positioning and movement of teeth. The most common example would be ‘braces’.
Corrective orthodontics
braces and retainers align dentition after bones have been weakened through a surgical procedure. As bones heal, teeth retain their new alignment
Accelerated osteogenic orthodontics
collaboration with other specialists to correct underlying conditions that are responsible for the malocclusion
Adjunctive orthodontics
. Another term for hyperodontia could be ____
a) macrodontia
b) polydontia
c) superodontitis
d) hemiodontic
B
With an open bite ____
a) posterior teeth do not occlude
b) molars do not occlude
c) incisors do not occlude
d) anterior teeth are absent
C
Accelerated osteogenic orthodontics ____
a) requires surgery
b) is used to correct the periosteum
c) increases the amount of supernumerary teeth
d) causes reverse articulation
A
Maxillary teeth protruding more forward than mandibular teeth is called ____
a) openjet
b) hyperjet
c) underjet
d) overjet
