Exam 2E Flashcards
Name 3 ways to treat overbite (deep bite)
incisor intrusion
molar extrusion
incisor proclination
How to accomplish incisor intrusion?
wire cinched/tied back to avoid proclination
high-pull headgear or TADs to limit molar extrusion
What devices to accomplish incisor intrusion?
Ricketts utility arch
Burstone’s intrusive arch
How to accomplish molar extrusion?
Alter bracket heights level curve of Spee anterior bite plates Class II elastics (but will also extrude upper anteriors) (most common Tx of deep bites)
How to accomplish incisor proclination?
side effect of Tx
may be used in Class II div 2 or Class III malocclusions where anteriors are retroclined
What causes a dental open bite?
habit - finger/tongue
What causes a skeletal open bite?
excessive vertical growth of the dentoalveolar complex
over-eruption of mandibular teeth
larger mandibular plane angle due to shorter mandibular ramus and opening rotation
How to fix skeletal open bite?
molar extractions
molar intrusions
MEAW (multi-loop edge archwire)
orthognathic surgery
What to use for maxillary dental protrusion?
distalizer
What to use for maxillary prognathism, dental flaring?
headgear
What to use for Mx retrognathism (incisors flared or upright), Mn retrognathism, flared lower incisors?
Extract U/L premolars
functional appliance
What to use for Mx retrognathism, flared incisors, Mn retrognathism, upright incisors?
funcional appliance
What to use for Mx prognathism, U/L incisor flaring (bimaxillary protrusion)?
Headgear
extraction of U/L premolars
What to use for Mn retrognathism?
functional appliance
What headgear to restrict anterior growth of Maxilla in HYPOdivergent patient (deep bite)?
cervical
