INTERCEPTIVE ORTHODONTICS
T/f
during first years, damage from habit is confined to anterior segment results to anterior open bite
T
T/f
after eruption of mandibular incisors result to permanent damage
T
What is the tooth size/arch length discrepancy in SERIAL EXTRACTION?
7-10 mm
T/f
arch length deficiency as compared to the tooth material is the most important indication for serial extraction,
T
T/f
ectopic eruption is one of INDICATIONS in SERIAL EXTRACTION

METHODS OF SERIAL EXTRACTION (3)
DEWEL’S METHOD
TWEED’S METHOD
NANCE
DEWEL’S METHOD
(1) Extract deciduous canines or Cs to align incisors (8-9 years)
(2) After 1 year, extract deciduous 1st molars or Ds (at 9-10
years) to accelerate eruption of permanent 1st premolars
(3) Extract the erupting permanent 1st premolars or 4s to allow the permanent canines to erupt in their place
deciduous Cs → deciduous Ds → permanent 4s
TWEED’S METHOD
(1) Extraction of deciduous 1st molar or Ds at 8 years
(2) After, extraction of permanent 1st premolars or deciduous
canines
deciduous Ds → permanent 4s or deciduous Cs
NANCE
Similar to Tweed’s method and involves extraction of deciduous 1st molars followed by extraction of 1st premolar and deciduous canines
T/f
SPACE GAINING THROUGH EXPANDERS is done prior to eruption of 7s or permanent 2nd molars
T
oral screen used to treat mouth breathing and cheek biting habits
Oral Vestibular Screen
used to treat lip biting, lip sucking and hypermentalis problems
Lip Bumper
prevents tongue from pushing towards the anterior teeth
Fixed Palatal Tongue Cribs w/ Loops
orthodontic and/or orthopaedic appliances which deliver force intraoral or to the chin from a coronal extraoral support
HEADGEAR THERAPY
anchorage is the nape of the neck
CERVICAL
→ causes distal and extrusive movements of upper molars to
increase lower facial height
→ indicated for Class II deep bite cases
CERVICAL
→ indicated for excessive overbite, overjet, Class II division I, convex profile
→ upward and backward direction of maxilla
OCCIPITAL
distal force straight through center of resistance by having
equal occipital and cervical movements
COMBINED OCCIPITAL AND CERVICAL
high angle case
A. High Pull Headgear
B. Straight Pull Headgear
C. Cervical Pull Headgear
A
normal angle case
A. High Pull Headgear
B. Straight Pull Headgear
C. Cervical Pull Headgear
B
low angle case
A. High Pull Headgear
B. Straight Pull Headgear
C. Cervical Pull Headgear
C
→ chin cup and occipital pull
→ mandibular prognathism
REVERSE PULL
inhibits or redirects growth of mandible
REVERSE PULL
any device, removable or fixed, designed primarily to affect skeletal and/or dental changes
FUNCTIONAL APPLIANCE
work by using the forces of facial muscles to alter the relationship of the teeth and arches
MYOFUNCTIONAL APPLICATION/PRE-ORTHO
used to guide growth in cases with mandibular deficiency (Class II) while correcting habits like tongue thrusting, mouth breathing, incorrect swallowing patterns
MYOFUNCTIONAL APPLICATION/PRE-ORTHO
→ usually dental corrections; not recommended for masking
skeletal abnormalities
CORRECTIVE ORTHODONTICS
treatment of established malocclusion in the permanent dentition, recognizing the existence of malocclusion and applying mechanical function or surgical treatment for correcting the malocclusion
