Edward Hartley Angle

introduced the classication of malocclusion that was universally accepted

Edward Hartley Angle

June 1, 1855 – August 11, 1930

Edward Hartley Angle

widely regarded as “The Father of American Orthodontics”

Edward Hartley Angle

He was trained as a dentist, but made orthodontics his specialty and dedicated his life to standardizing the teaching and practice of orthodontics.

Edward Hartley Angle

During his lifetime, Angle has been credited with introducing the following appliances to the eld of Orthodontics

EDGEWISE BRACKET

Most important contribution to Orthodontics of Edward Hartley Angle

E (expansion) Arch Appliance (1907)

This appliance only allowed tipping movement and provided poor control of individual tooth position.

a. Basic

b. Ribbed

2 types of E (expansion) Arch Appliance (1907)

- Lock pin arch wires will be tied to large arch wire of a small jaw

- will result to expansion of the jaw labially and buccally

- expansion of jaw, teeth will move out to a bigger circumference/perimete

MECHANISM/PROCESS of E (expansion) Arch Appliance (1907)

Pin & Tube Appliance (1910)

Consisted of Gold and Platinum bands and had attachment to all the teeth.

Pin & Tube Appliance (1910)

These bands had vertical tubes that were soldered to them and a Pin was passed through it to achieve tooth movement.

Pin & Tube Appliance (1910)

Root parallelism and rotation was difcult to achieve with this appliance.

Pin & Tube Appliance (1910)

In addition, the pins had to be repositioned every appointment through the process of re-soldering

- Gagawa ka ng isang arch then wielding yung mga vertical ube niya then i-shshoot dyan

- the teeth will follow the wire

MECHANISM/PROCEDURE of Pin & Tube Appliance (1910)

Ribbon Arch Appliance (1915)

This appliance was created after the Pin and Tube appliance.

Ribbon Arch Appliance (1915)

This device consisted of a Vertical bracketsoldered to a band.

Ribbon Arch Appliance (1915)

It allowed rotation to be possible.

Ribbon Arch Appliance (1915)

Dr. Raymond Begg eventually used this appliance to create his light wire technique.

Ribbon Arch Appliance (1915)

- makes use of rectangular wire

- for the control of the roots

- heavy wire

Ribbon Arch Appliance (1916)

- Modied the bracker

Ribbon Arch Appliance (1916)

- Open occlusally

Ribbon Arch Appliance (1916)

Rectangular arch tted into a machined bracket

Ribbon Arch Appliance (1916)

0.022 x 036-in gold, held rmly with pins

Ribbon Arch Appliance (1916)

small enough to have good spring qualities

Ribbon Arch Appliance (1916)

lacked premolar contro

Edgewise Appliance (1925)

These were identical bracketsfor all teeth

Edgewise Appliance (1925)

It allowed tooth movement in all 3 planes of space by adding bends to the rectangular arch-wire, one of its disadvantages.

Edgewise Appliance (1925)

The wire was held in the slot by metal ligature

Edgewise Appliance (1925)

○ In this appliance, the slot was changed from vertically to horizontally.

○ Therefore, the bracket was wide mesio-distally and its slot size was .022 x .028 inch.

○ These brackets were initially referred to as "open face" or "tie brackets".

e edgewise bracket

The ______ has been later modified to Single Width Bracket, Siamese Bracket, Lewis Bracket, Steiner Bracket, Broussard Bracket.

Edward Hartley Angle

His increasing interestin dental occlusion and in the treatment necessary to obtain normal occlusion led directly to His development of orthodontics as a specialty

The development of Angle's classication of malocclusion in the 1890s

s an importantstep in the development of orthodontics because it not only subdivided major types of malocclusion but also included the rst clear and simple denition of normal occlusion in the natural dentition.

Edward Hartley Angle

He was concerned with the aesthetics of orthodontics as well as functionality

Dr. Martin Dewey

divided Angle's class I & III into further types

1. Past president of the American Association of Orthodontist and American Dental Association

2. Founding editor of International Journal of Orthodontia

3. Stressed the importance of a blend of the biologic and mechanical aspects of orthodontics.

- MECHANICAL aspect: putting wires or appliance

- BIOLOGIC; when you consider that the tooth is alive

4. Modied the classication system of Angle (Dewey’s Modification

extraction to correct crowding

Dr. Calvin Suveril Case

the spaces from the extracted area will be used up for alignment of the crown of the teeth

Dr. Edward Angle

for expansion, non extraction

Dr. Edward Angle

upon removal of appliance, there’s relapse, crowding again, because there are tight muscles

Albert Ketcham

He investigated the problem of root resorption.

Albert Ketcham

His study awakened a feeling of"biologic sense"; and existence of pathologic results of improperly guided orthodontic treatment.

Albert Ketcham

Root Resorption

- pathologic result, root resorption is one of this

- heavy forces will result to root resorption

- irreversible
