Saturday, February 4, 2017www.drdentiste.com3The word ORTHODONTICS is derived from Greek words

Orthos : correctOdontos : teeth

Saturday, February 4, 2017www.drdentiste.com4In 1922, the British Society for Study of Orthodontics has defined the specialty as Orthodontics includes study of growth and development of jaws and face particularly and body generally as influencing position of teeth; study of action and reaction of internal and external influences on the development ; prevention and correction of arrested and perverted development

AIMS & OBJECTIVESSaturday, February 4, 2017www.drdentiste.com51 .Functional efficiency2. Structural balance3. Esthetic harmony

Structural balanceSaturday, February 4, 2017www.drdentiste.com6Orofacial region consists of dentoalveolar system, skeletal tissue and soft tissue including musculature.

It depends upon on the correct proportion of the tooth substance to bone development when latter has reached its growth limit in order to permit satisfactory alignment of teeth .

Functional efficiencySaturday, February 4, 2017www.drdentiste.com7It depends upon correct relationship of teeth to each other and their orientation to skull as a whole to permit a satisfactory excursion of the mandible in function of mastication .

Esthetic harmony:Saturday, February 4, 2017www.drdentiste.com8It is a matter of proportion in shape, size and orientation of dental organs as a whole in their relationship to other facial factors.

Saturday, February 4, 2017www.drdentiste.com9This goal is not just cosmetic.It reflects the patients desire to improve their social acceptability and eliminate discrimination based on appearance, which can affect their quality of life greatly.

The goal of orthodontic treatment

Saturday, February 4, 2017www.drdentiste.com10To improve patients life by enhancing dental and jaw function and dentofacial esthetics.

From this perspective Role of orthodontic treatment is analogous to that of several other medical specialities such as plastic surgery and orthopedics,in which patients problem often doesnt result from disease but distortion of development.

2. Predisposition to periodontal diseases

Saturday, February 4, 2017www.drdentiste.com133.To close diastema

4. Mouth breathing

5. Correction of speech defects

6. Risk of trauma: Class II malocclusion

Saturday, February 4, 2017www.drdentiste.com147. Bruxism

8. Tmj probs: deep bite, occlusal prematurities.

9. Surgical treatment for congenital defects : Cleft lip and palate. 10 .Correction of shifted teeth, prior to construction of bridges and partial dentures.


Skeletal problems

Skeletal problems result not from malpositioned teeth or well proportioned jaws but from disproportion in size or position of jaws themselves.

Occurs in all three planes

Preventive Orthodontics

Prevention is better than cure

Actions taken to preserve the integrity of what appear normal for that age

Space maintainence

Check up for oral habits and habit breaking appliance if required

Saturday, February 4, 2017www.drdentiste.com21Interceptive Orthodontics

Procedure undertaken at early stage of MO to eliminate or reduce the severity of the same, in order to prevent establishment of full fledged MO that may require long term orthodontic treatment at later age.

Control of abnormal habits

Interception of skeletal malrelation using myofunctional appliance

Saturday, February 4, 2017www.drdentiste.com22 Corrective Orthodontics

Surgical orthodontics: Done for patient with no remaining growth potential and severe malocclusion.

Dentofacial orthognathic surgeries are the major surgical procedures carried out along with orthodontic therapy.Require a team approach with oral surgeon and orthodontist being imp member of team

Saturday, February 4, 2017www.drdentiste.com23Currently a new technique of bone generation in craniofacial region termed Distraction Osteogenesis has been introduced.

It is a biologic process of new bone formation between osteotomised bone segments that are seperated gradually by incremental traction.

Traction force is applied to bone segments,creating a tensional stress in repairative callus that joins the divided bone segments.




Saturday, February 4, 2017www.drdentiste.com27B) Camouflage

Bringing the teeth in proper occlusion without correcting jaw discrepancy.Underlying skeletal discrepancy be corrected by orthodontic tooth movement.Successful for adolescents with moderate problems.

Not useful 1. In transverse or vertical skeleton problems2. Severe class II and III


Adjunctive treatmentSaturday, February 4, 2017www.drdentiste.com29It facilitates restorative treatment by repositioning the teeth so that more ideal and conservative technique can be used.

1.Repositioning teeth that have drifted.2. Forced eruption of badly broken Teeth.
