DASLE: Orthodontia 2025 with
complete verified solutions
malocclusion can compromise all aspects of oral function: - answer -
chewing can be difficult if teeth do not occlude
-jaw discrepancies can force changes in the manner of swallowing
-malocclusion can make it more difficult for particular speech sounds to be
made
-TMJ pain can arise from minor imperfections in occlusion that trigger
clenching and grinding activities
Orthodontic treatment can eliminate or reduce adversity for the pt in
three areas: - answer psychosocial problems, oral malfunction, and
dental disease
orthodontic problems result from - answer developmental, genetic, and
environmental influences
development causes - answer -congenitally missing teeth
-malformed teeth
-supernumerary teeth
-interference with eruption
-ectopic eruption
genetic causes - answer -malocclusion
- child who inhibits a mothers small jaw and a fathers large teeth
-missing tooth
environmental causes - answer injuries can occur at birth in two major
categories: fetal molding and trauma during birth
, fetal molding - answer occurs when an arm or leg of the fetus is pressed
against another part of the body, such as when an arm is pressed against
the mandible. Pressure can lead to distortion of rapidly growing areas
trauma during birth - answer injury to the jaw, may occur during the
actual birth, particularly with the use of forceps in delivery
Dental trauma can lead to development of malocclusion in three ways -
answer -damage to permanent tooth buds when an injury to primary
teeth has occurred
-movement of a tooth or teeth as the result of premature loss of a primary
tooth
-direct injury to permeant teeth
habits that affect the dentition - answer tongue thrusting, tongue thrust
swallowing, thumb and finger sucking, bruxism and, mouth breathing
Class I malocclusion (neutrocclusion) - answer normal relationship
between 1st molars, but there are individual teeth in arch that are
slanted/twisted/abnormal
Class II malocclusion (distocclusion) - answer the mandible is in an
abnormal distal relation ship to the maxilla. The maxillary anterior teeth
protruding over the mandibular anterior teeth
Class III Malocclusion (mesioclusion) - answer the body of the mandible is
in an abnormal mesial relationship to the maxilla. The mandibular anterior
teeth protruding in front of the maxillary teeth, referred to as an
underbite
overjet - answer excessive protrusion of the maxillary incisors causing
space or distance between the facial surface of the mandibular incisors
and the lingual surface of the maxillary incisors
overbite - answer Increased vertical overlap of the maxillary incisors
