Profile oriented orthodontic treatments

4. Classification :
 Straight Profile
 Convex Profile
 Concave Profile

5.  In this profile, the person will have neither the
intentional character of the concave type or the
demanding nature of the convex type. Their
face is a moderation between the two profiles

7.  Convex profile includes sloping forehead,
slightly prominent brows and large slightly
curved nose. Further, people of convex type
have a receding chin shape.

9.  Concave profile comes with a prominent
forehead and almost flat eyebrows. The nose is
bent or smaller and straight or slightly curved
inward. There is usually flat and chin is well
formed with an outward curve.

12. Convex profile is most common profile which is
associated with Skeletal Retrusion, DentoAlveolar
Retrusion & Class II Dental malocclusion further
divided into
 Class II Division 1
 Class II Division 2

13. A malocclusion where the molar relationship
shows
the buccal groove of the mandibular first molar
distally positioned when in occlusion with the
mesiobuccal cusp of the maxillary first molar.

14. Division 1

15. Division 2

16. Treatment Objectives
 Reduction of overjet
 Reduction of overbite
 Correction of crowding and local irregularties
 Correction of unstable molar relationship
 Correction of posterior crossbite if any
 Normalize musculature

17. In case of skeletal irregularities
 surgically maxillary setback (in case of
maxillary prognathism)
 surgically mandibular advancement(in case of
mandibular retrognathism)

18. In patients beyond growth modification
In order to obtain space teeth are extracted from
both the upper and lower arch i.e First premolars
Second premolars can also be extracted in
minimum anchorage cases

20. Based on underlying skeletal pattern a maxillary
setback or maxillary advancement is undertaken
along with orthodontic bracket system

22. In case of class II Division 2
Overjet and overbite of incisor reduced
Intrusion of incisors may be done and then move
palatally/lingually .
