Q

What is the tooth size/arch length discrepancy in SERIAL EXTRACTION?

Q

T/f

A

T

Q

METHODS OF SERIAL EXTRACTION (3)

A

DEWEL’S METHOD

TWEED’S METHOD

NANCE

Q

DEWEL’S METHOD

A

(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

Q

TWEED’S METHOD

A

(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

Q

NANCE

A

Similar to Tweed’s method and involves extraction of deciduous 1st molars followed by extraction of 1st premolar and deciduous canines

Q

T/f

SPACE GAINING THROUGH EXPANDERS is done prior to eruption of 7s or permanent 2nd molars

A

T

Q

oral screen used to treat mouth breathing and cheek biting habits

A

Oral Vestibular Screen

Q

used to treat lip biting, lip sucking and hypermentalis problems

A

Lip Bumper

Q

prevents tongue from pushing towards the anterior teeth

A

Fixed Palatal Tongue Cribs w/ Loops

Q

orthodontic and/or orthopaedic appliances which deliver force intraoral or to the chin from a coronal extraoral support

A

HEADGEAR THERAPY

Q

anchorage is the nape of the neck

A

CERVICAL

Q

→ causes distal and extrusive movements of upper molars to
increase lower facial height
→ indicated for Class II deep bite cases

A

CERVICAL

Q

→ indicated for excessive overbite, overjet, Class II division I, convex profile
→ upward and backward direction of maxilla

A

OCCIPITAL

Q

distal force straight through center of resistance by having
equal occipital and cervical movements

A

COMBINED OCCIPITAL AND CERVICAL

Q

high angle case

A. High Pull Headgear
B. Straight Pull Headgear
C. Cervical Pull Headgear

Q

→ chin cup and occipital pull
→ mandibular prognathism

A

REVERSE PULL

Q

inhibits or redirects growth of mandible

A

REVERSE PULL

Q

any device, removable or fixed, designed primarily to affect skeletal and/or dental changes

A

FUNCTIONAL APPLIANCE

Q

work by using the forces of facial muscles to alter the relationship of the teeth and arches

A

MYOFUNCTIONAL APPLICATION/PRE-ORTHO

Q

used to guide growth in cases with mandibular deficiency (Class II) while correcting habits like tongue thrusting, mouth breathing, incorrect swallowing patterns

A

MYOFUNCTIONAL APPLICATION/PRE-ORTHO

Q

→ usually dental corrections; not recommended for masking
skeletal abnormalities

A

CORRECTIVE ORTHODONTICS

Q

treatment of established malocclusion in the permanent dentition, recognizing the existence of malocclusion and applying mechanical function or surgical treatment for correcting the malocclusion
