Risks and Benefits in Orthodontics Flashcards
name 3 factors related to appearance which may be helped by orthodontic treatment
Teasing/ bullying - teasing experienced particularly by people with increased overjets
children with ‘normal’ dental appearance judged by peers and adults to be more friendly, intelligent and less aggresive
QoL improvements
people with ‘unattractive’ faces perceived unfavourably
does orthodontic treatment improve speech defects
very rarely
what does MOCDO stand for
missing teeth - including impaction
Overjet (increased >6mm)
cross bites - anterior and posterior
displacement on contact points (crowding)
overbites - deep AND traumatic
why should missing / ectopic teeth get ortho treatment
aesthetics
root resorption
cyst formation
why treat overjets >6mm
trauma risk
bullying
why treat anterior and posterior crossbites
asymmetric growth
toothwear
gingival recession
why treat displacement of contact points
aesthetics
caries risk
perio risk
why treat overbites
trauma and gingival stripping
what is decalcification
weakening and erosion of enamel appearing as white chalky spots that are more susceptible to caries
name 3 ways decalcification risk can be minimised
Good case selection - motivated patient, good OH pre treatment, low caries risk
Fluoride - fluoride exposure at least 2x daily, duraphat for high risk , FV 4x year
OHI - tailored individual advice, interdental brushed/ superfloss, brush after every meal
Dietary Advice - concerning amount and frequency , avoid snacks between meals
what is the average amount of root resorption seen over a 2 year course of fixed appliance treatment
1mm
what are the 3 most commmonly affected teeth by root resorption
maxillary incisors
mandibular incisors
first molars
what types of tooth movement are an increased risk of root resorption
prolonged high forces
intrusion
torque
name 3 risk factors for orthodontic root resorption
previous trauma
nail biting
blunt or pipette shaped roots
shortened roots with evidence of previous resorption
what is orthodontic relapse
return of original malocclusion features following orthodontic correction
