1. INTRODUCTION OF
ORTHODONTICS
Dr. Abdul Jabbar
BDS, FCPS, FFD RCSI (UK)
Assistant Professor
LUMHS, Jamshoro.

2. ORTHODONTICS
Concerned with
Facial Growth
Development of Dentition & Occlusion
Diagnosis, Interception and Treatment of Occlusal
Anomalies

3. Definition by AAO
Concerned with
Supervision, Guidance & Correction
of the growing and mature Dento-facial structures

4. Creates
Delicate balance between
Aesthetics
&
Occlusion

5. PREVALANCE OF MALOCCLUSION
In U.K
66% of 12 yrs old require orthodontic treatment
33% need Complex treatment
At de`Montmorency College of Dentistry
60% population need treatment

6. NEED FOR TREATMENT
 No treatment should be embarked upon unless a
demonstrable benefit to the patient is feasible
 Risk Benefit Analysis
 Finances in Orthodontics

7. DENTAL HEALTH
1) Caries
Weak association b/w malocclusion & Caries
2) Periodontal Disease
Weak association b/w malocclusion & periodontal disease

8. PSYCHO-SOCIAL WELL BEING
Positive effect on Psycho-social well being & Self esteem

9. DEMAND FOR TREATMENT
Treatment demand & Treatment need does not correlate with each
other
Willingness to undergo orthodontic treatment is greater in followings
 Females
 Higher Socio-economic Families
 Areas with smaller Population to Orthodontist Ratio
 Occlusal Disharmony

10. DISADVANTAGES OF TREATMENT
Root Resorption (1mm / 2 yr)
Loss of Periodontal Support
Decalcification
Soft Tissue Damage

11. EFFECTIVENESS OF TREATMENT
Diagnosis & Treatment Planning
Execution of Bio-Mechanics
Patients Co-operation

12. TMJ & ORTHODONTICS
Some claims Ortho. Rx contributes
Some claims beneficial effect
Prevalence of Malocclusion (50 – 75 %) does not match
with Prevalence of TMD`s ( 5 – 30 %)

13. DIVISION OF ORTHODIAGNOSIS
Preventive Orthodontics
Interceptive Orthodontics
Corrective Orthodontics
Surgical Orthodontics

14. PREVENTIVE ORTHODONTICS
Action taken to preserve the integrity of what appears to be normal at
specific time.
E.g.
Early correction of caries on distal surface of e`s
Early recognition & elimination of oral habits
Space maintainer

15. SPACE MAINTAINER

16. SPACE MAINTAINER

17. TONGUE CRIB
Management of Tongue thrust

18. INTERCEPTIVE ORTHODONTICS
Concerned with recognition & elimination of
Potential irregularities & Malpositions in the developing
dento-facial complex
E.g.
Serial Extraction

19. SERIAL EXTRACTION

20. SERIAL EXTRACTION
Ext of “ C ”

21. SERIAL EXTRACTION
Ext of “ d ”

22. SERIAL EXTRACTION
(Ext of “ 4 ” & achieving occlusion)

23. CORRECTIVE ORTHODONTICS
Recognizes
Existing malocclusions & the need for employing mechanics to
reduce / eliminate the malocclusion

24. Skeletal class III Case

25. Skeletal class III Case
Post-Treatment Photographs

26. SURGICAL ORTHODONTICS
Combined orthodontic & surgical management of severe Skeletal
problems of MAXILLO-MANDIBULAR region in an individual
where active growth is completed

27. Skeletal Class III

28. Skeletal Class III
