Fixed Appliences

INDIAN DENTAL ACADEMY Leader in continuing dental education

Evaluation of Fixed Appliances in Brief Dr.Edward Angel

- 1926.

- Father of Modern Orthodontics - School of Orthodontics - Edgewise Appliance - 1st bracket, Band - Classification of mal-occlusion - Proponent of non extraction treatment.


Bracket Slot Rectangular slot

Rectangular wire insertion for 3 dimensional control Followers of Dr.Edward Angel - Dr. Tweed - Dr.Begg Dr.Tweed popularized edgewise technique and extraction therapy. Dr.Begg popularized Beggs technique and extraction therapy.

Begg Technique Light wire technique, Round Wire technique. Tooth movement is sequential and divided in to three stages. 1st stage- Alignment, decrowding correction of deep bite bite and over jet. 2nd Stage- Retraction of teeth and closure of all the spaces. 3rd Stage- Root uprighting and torquing. 4th Stage- Finishing and detailing

Features of Begg technique -1st and 2nd stages mainly include tipping of teeth - In the 3rd stage tooth uprighting is done and torque is done. - Connection of root inclination in Labio lingual direction is called as torquing of roots.

Uncontrolled tipping Control Tipping

Edgewise system Bodily Movement of teeth can be achieved In 1971 Andrews Edgewise system

introduced Preadjusted

-Built in Tip and Torque in Brackets -Reduction of number of stages -Esthetically pleasing bracket system -Excellent finishing and detailing.

Recent Advances in PEA •

Esthetic Brackets

Composite Brackets, Plastic Brackets, Ceramic Brackets

Titanic Brackets (Nickel Free)

Segmental Approach to reduce the treatment time and more comfortable to patient.

Begg Technique Advances Tip Edge - Concept of both Beggs and Edgewise technique - Concept of light wire technique continued - Rectangular wire finish - Bracket design more pleasant and comfortable than Beggs Brackets.

Orthodontic Treatment Planning

Class I Malocclusion Skeletal Class I -Proclination -Bimaxillary protrusion -Crowding -Spacing -High labial positioned canines.

Proclination: -With space - Without spacing

Pre treatment profile, Age:15yrs

Crowding -Mild -


-Moderate -Severe -

3-6mm 6 and above

Class II cases: Every growing period 1. Maxillary prognathism Mandibular Normal 2. Maxillary Normal Mandibular deficient

Vertical growing Horizontal growing

Treatment plan: to hold maxillary growth in anterior and posterior plane and vertical plane. Head gear can be given. Following to orthopaedic treatment, fixed treatment can be started in permanent dentition.

Vertical maxillary excess long face, incompetent lips, proclined incisors, infantile swallowing pattern

Skeletal open bite with long face syndrome

Maxillary intrusion splint, with habit breaker, with headgear.

Post orthopedic appliance


Maxillary Normal


Mandibular deficient

Treatment plan: Functional Appliance Therapy to advance the mandible: -Activator -Twin block -Bionator This is followed by fixed appliance therapy.

Class II Combination •

Prognathic Maxillary


Retrognathic mandible

Treatment Plan: Head and gear and Functional appliance

Class II non growing: 1. Maxillary forward 2. Mandibular back.

Orthodontics -

Caumafluege 1. Upper extraction only 2.

Late growing years • Fixed functional appliances 1. EVA Appliance 2. Jasper Jumper 3. S.U.S. Device 4. Fixed Twin Block 5. Herbst Appliance 6. Class Corrector

Class II Div. Feature : a. Usually Mandible / Chin Prominent b. ‘U’ Shape arches c. Cetrals retroclined d. Deep bite.

Treatment Plan: 1. Alignment of incisors 2. Intrusion of incisors and correction of deep bite 3. Some times mandibular relocation takes place in to class I 4. Growth Modulation through functional appliance if no relocation.

Class III Growing • Retraguathic Maxilla • Normal Mandible 6-9 years: Face mask, reverse pull head gear 9-13 years: Facemask with rapid palatal expander

RPE to split the sutures and facilitates the translation of maxilla forward. After 16 years Orthognathic Surgery

Growing mandible: - Chin Cup - Observe the mandible thought the growth period. - May require surgery at end of growth period.
