Sweep 1.1 Flashcards
(43 cards)
Band & loop
● Loop contacts, but doesn’t encompass—— → allows ——- when lateral incisor erupts
1° canine
lateral canine movement
Band and loop
● Loop wide enough for —–
premolar eruption
Band and loop
■ Recall every —- months
3-6
● Distal shoe
○ Indication ⇒ ONLY when —— lost before eruption of —–
primary 2nd molar
permanent 1rst molar
● Distal movement of max. molars (in Class II correction)
○ Class II elastics less effective
Applications of TAD:
- Holding arches
○ Construct with ——– (facilitates tooth alignment)
■ ———- most reliable; typically keyhole design used
○ Resolves —— discrepancies
○ Limitations as a tooth mover:
■ No —–
■ Difficult to move teeth with ——- (can be uncomfortable)
ideal arch form
Soldered arches
faciolingual
rotation
heavy wire
- Holding arches with tooth movement
○ LLHA controls —– & coordination
■ Can control —– and move teeth (primarily via tipping)
■ NOTE: Flat anterior segment does NOT resolve around an ideal arch form
○ LLHA can be used as —–
○ LLHA biomechanics may require adjustment
■ Heavy tipping force, so needs to be placed ——- on teeth you want to move
arch form
arch length
retainer
passively
Generalized spacing with protrusion:
○ Fixed appliance
■ Bracket & tube; —— contact
■ Bodily movement with anchorage on ——
molars
2 point
Generalized spacing with protrusion: ○ Removable appliance with labial bow ■ ----- contact → tips uppers ------ ■ Anchorage to -------- (& palate) ● Retention via ------- ■ --- month treatment ● Activated -------- movement per month
One-point
lingually
posterior attachment
adams clasp
< 6
2 mm for 1 mm
● Diastema Treatment options:
○ Tipping with finger spring
■ Reciprocal —-
■ Removable provides short term retention; long term with ———
anchorage
lingual bonded retainer
● Diastema Treatment options:
○ Bodily movement with any archwire (round or rectangular) - reciprocal anchorage
■ Long term retention with ——-
lingual bonded retainer
● Expansion of ——– least stable
lower canine
● Late growth:
○ Maxilla —— growth & Mandible ——- growth post-adolescence
downward
forward
○ Women ⇒ more ——— growth; Men ⇒ more ——— growth
maxillary
mandibular
Class II mandibular retrusion:
● Treatment with functional appliances
○ Brings mandible ——, ————- & allowing ——- growth
○ Forces push mandible forward & maxilla backward → upper teeth ——; lowers —–
forward
unloading condyle
mandibular
retrude
protrude
Class II mandibular retrusion:
● Example of functional appliance pt:
○ Mandible comes forward more than ——
○ Maxilla maintains normal
downward
downward growth, but less forward growth
Class III maxillary retrusion
● Treatment with —–
○ Can expect—– mm of forward maxilla growth in year
○ Mandible ——- → patient profile becomes more convex
○ Upper incisor protrusion
● Only effective in children ——— - before sutures fuse
facemask - reverse pull headgear
2-3
rotates down & back
< 10-11 y/o
When is early treatment justified: ● For class II ⇒ based on
benefits of esthetics or trauma reduction
When is early treatment justified: ● For class III ⇒
True maxillary deficiency
also:
● Posterior crossbites
Fracture healing phases:
● Inflammation → ——
● Soft callus → ——— to form around & inside fracture site
● Hard callus → —— to form inside/around fx site; bone ——
● Remodeling → newly formed bone remodeled; bone resorbed to its original condition
bone fractured
soft tissue starts
minerals start
reunites
● Start growth modification at CVMS
2 or 3
○ Stage 3 indicates peak growth
● Reverse pull → growth modification started late, so only ——- effect (upper proclined)
camouflage
Combination of distal crown tip & mesial root tip
● Goal is distal crown tip, but want to prevent extrusion
○ To prevent extrusion → use
T-loops or helical mechanics to intrude tooth &/or move roots mesially
Congenitally missing maxillary lateral incisors
● Treatment plan depend on pt:
○ Class II with overjet →
treat canine as lateral & close space to reduce overjet
