Ortho prevention Flashcards
why can fixed appliances cause demineralisation?
predispose to plaque accumulation - impedes cleaning
white markings - cavitation
what should be done pre tx r.e caries?
rev OH and diet
prevention of demineralisation?
F MW during tx
prevent or remove stagnation areas
reduce flash around brackets
GI on bonds - F release
what is the average root resorption seen in pts?
1mm loss
what teeth are most commonly affected by root resorption?
anteriors
what increases the risk of root resorption during tx?
pts with prev resorption
prev trauma
root filled may be at a greater risk
how to prevent root resorption?
lighter forces
shorter tx
if at risk - repeat radiographs every 6 months
what is the pain on fitting of a brace due to?
transient pulpal ishcaemia
tooth movement may cause what periapically?
a flare up of a tooth with periapical history
what puts a pt at risk for pulpal damage?
prev trauma - increased risk of pulpitis
trauma during tx
rotary instruments
how to manage pulpal problems?
pulpal ischaemia 2-7 days post fitting
paracetamol
why is ibuprofen contra indicated to ease ortho pain?
may impede movement
why is gingivitis a risk with ortho?
increased gingival inflammation due to reduced access for cleaning
apical migration of perio attachment and alv bony support during tx
why might perio problems require ortho?
lower incisor in crossbite can lead to attachment loss
what might cause palatal inflammation?
a removable appliance
if reduced perio support during tx what should be done?
lower strength of forces
pts should have what to reduce gingivitis risk during ortho tx?
3 monthly scale and polish
what soft tissue damage might an appliance cause?
traumatic ulceration
friction against appliance
archwire not tucked out of way
clumsy instrumentation
what can be used to ease pain of ulceration?
wax
chlorhexidine
how is headgear made safer?
neck strap to prevent displacement
prevention of recoil of headgear
what are some problems with implants?
(used as temp. anchorage)
poor success as no oseo integration
risk of perforation of roots - infection
what may pts have an allergy to?
nickel or latex
what could cause burns in ortho?
chemical - etch
physical - handpieve overheating
why can tx end up being prolonged?
failed apps
not wearing appliance or elastics as advised
breakages
why can there be problems with an essix retainer?
can fracture easy
why can there be problems with a hawley retainer?
not good at rotation maintenance
why can there be problems with a bonded retainer?
reduced access for cleaning
