B

science and art of orthodontics that deals with recognition and elimination of potential irregularities and malposition of the developing dentofacial complex

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

T

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

CORRECTIVE ORTHODONTICS
