Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

3. INTRODUCTION
The achievement of a stable,
functional & esthetic arch form has
long been one of the prime objectives
of orthodontist from the period of
Edward Angle.
www.indiandentalacademy.com
4. SEARCH FOR IDEAL ARCH FORM
1. Bonwill –1885
Tripod shape of lower jaw
Equilateral triangle
Base – Condyle to Condyle
Sides – Condyle to midline
Bicuspids & molars formed a straight
line from cuspid to condyle
2. Hawley -1905www.indiandentalacademy.com
5. Bonwill -Hawley Arch Formula
Anterior teeth should be made to lie
along a circle whose radius
equaled their combined widths
Equilateral triangle
Base – Intercondylar width
Should be used only as a guide in
establishing arch form
www.indiandentalacademy.com
7. 3. Black -1902
Upper teeth are arranged in a
semi-ellipse & lower teeth were
arranged on a smaller curve.
www.indiandentalacademy.com
8. 4. Broomel -1902
The teeth are arranged in the jaws in
the form of two parabolic curves, the
superior arch describing the segment of
a larger circle than the inferior , as a
result of which the upper teeth slightly
overhang the lower.
www.indiandentalacademy.com
9. 5. Angle –1907 – Line of occlusion
Definition
The line with which, in form & position
according to type, the teeth must be in
harmony if in normal occlusion.
• This line resembles parabolic curve
but varies due to
Race
Type
Temperament of the individual
www.indiandentalacademy.com
10. LINE OF OCCLUSION
•Upper
Molar – central fossa
Anterior- cingulum
•Lower
Molar – buccal cusps
Anterior –incisal edges
www.indiandentalacademy.com
11. Angle -1907
Bonwill –Hawley Arch form- General
approximation of the
true line of occlusion
Objected the straight line from
cuspid to third molar
Straight line existed from the cuspid to
the MB cusp of the I molar,however,
there was a natural curvature needed in
the molar region.
www.indiandentalacademy.com
13. 7. Chuck, 1934-AO –Ideal arch form
Square
Round
Oval
Tapering
•BH archform – not suitable for every
patient, can be used as a template
•Bicuspid region should be wider than
the cuspids to prevent excessive
expansion of the cuspids.www.indiandentalacademy.com
14. 8. Boone AO-1963
Similar superimposition of the BH
archform on a mm template.
9. Mac Conaill & Scher 1949
It is impossible for an ellipse & a
parabola to meet one another at every
point.
www.indiandentalacademy.com
15. Mac Conaill 1949
Catenary curve – Ideal curve of common
occlusion
Catenary curve is formed by suspending
a chain or flexible cable of appropriate
length from two points of varying width
www.indiandentalacademy.com
16. Broodie & Lillie 1966
Basic bony arch is established as
early as 9.5 weeks in utero & the arch
was of a catenary design
Scott 1957
Shape of the human arch - Catenary
curve
www.indiandentalacademy.com
17. Disadvantage of Catenary curve
Does not give a good fit in the
II & III molar region
www.indiandentalacademy.com
18. 10. Musich –1973, AJO
Catenometer –Device for construction
of arch perimeter
11. Brader –1972-AJO
Dental arch form was made up of teeth
which assume unique positions along a
compound curve representing an
equilibrium at all points and delimited by
the counterbalancing forces of the
tongue and circumoral tissues.
www.indiandentalacademy.com
20. Brader arch form
The geometry of the
dental arch form was best
represented by a Trifocal
ellipse, with the teeth
occupying the portion at
the constricted end of the
curve.
www.indiandentalacademy.com
22. Brader arch form
Arch guide with 5 arch forms
Selection of proper form –Arch width
at the II molars
Maxillary arch form is selected one
size larger than the mandibular arch
form
Drawback – Excessive narrowing in the
cuspid region & excessive wear of the
incisal portion of the cuspidswww.indiandentalacademy.com
23. 12. Rocky mountain Data systems –
Computer derived Arch design
• Inter molar width
• Inter cuspid width
• Arch depth
• facial type
www.indiandentalacademy.com
27. Functional anatomy
Although bone is the hardest tissue in
the body, it is one of the most responsive
to change when there is an alteration in
the musculature.
The dental arch form is initially shaped
by the supporting bone & following
eruption of teeth, by the musculature &
intraoral functional forces.www.indiandentalacademy.com
30. Balance of muscle forces & Arch form
•Between the tongue and perioral
musculature, there is no balance of
force
• During swallowing tongue pressures
are considerably greater than those
exerted by the cheeks & lips
www.indiandentalacademy.com
32. Buccal forces operate constantly
throughout the day.
Occlusal forces also help to maintain
the equilibrium.
Dental equilibrium – Dynamic equilibrium
Posterior teeth may be moving buccally
during swallowing, but the forces of
the cheeks return them to a more
lingual position, occlusal forces also
produce buccolingual movementswww.indiandentalacademy.com
33. Facial form Vs Arch form
Leptoprosopic – Narrow dental arches
Euriprosopic - Broad, round arches
Mesoprosopic – Average/ parabolic
arches
www.indiandentalacademy.com
35. Malocclusion
Class II – Narrow & Tapered maxillary
arch form
- Ovoid mandibular arch form.
Class III- Tapered mandibular arch form
- Ovoid maxillary arch form.
www.indiandentalacademy.com
36. Stanley Braun et al –AO, 1998
Class II
Maxillary arch – Narrower
Mandibular arch – width & Depthz
Class III
Maxillary arch – Arch width
Mandibular arch - Arch width
Arch depthwww.indiandentalacademy.com
37. Habits
Thumb sucking – Narrow dental
arches
Tongue thrusting – Narrowing of
the
maxillary arch
www.indiandentalacademy.com
39. Basic components
• The anterior curvature
• Inter cuspid width
• Inter molar width
• Curvature from cuspids to II molars
www.indiandentalacademy.com
40. VARI SIMPLEX DISCIPLINE ARCH
FORM
•Not based on clinical examination
•Result of research by Dr. Garland
McElvain
www.indiandentalacademy.com
41. Final arch form
•Fitted to the original study model of
the mandibular arch
• cuspids should not be expanded.
• Wax bite of the maxillary arch is
examined
• Mandibular II molars – toe in
www.indiandentalacademy.com
42. Roth – Tru Arch form
•Modified catenary curve
•5 separate radii
•Over correction concept
www.indiandentalacademy.com
43. MBT ARCH FORMS
Arch forms – Tapered
[Chuck-1934 ] Square
Ovoid
MBT - 3 Archforms in early treatment
Individual archform in final stages
These archforms vary mainly in interPm,
intercanine width of 6mm.

51. The normal variation in arch form, are
not reflected in the preformed arch wires
presently available & it is important to
keep in mind during orthodontic
treatment that if preformed arch wires
are used, their shape should be
considered a starting point for the
adjustments necessary for proper
individualization.

Defined arch forms using the following
parameters
•Inter II molar width
•Inter canine width
•II molar depth
•Canine depth

Arch form, particularly in the
mandibular arch, cannot be permanently
altered during appliance therapy.

57. Strang , AO- 1949, AJO- 1946
Howes, AJO- 1960
Inter molar width was normally
decreased during extraction Rx,
however, that if cuspids were moved
distally into extraction sites, they
could be expanded buccally to limits
offered by their new distal location.www.indiandentalacademy.com
58. Amott-1962, Arnold-1963,Welch-1956
Bishara AJO-1973
With regard to extraction cases,
intermolar width decreased post Rx, but
inter cuspid width which retained its
original dimension did not show an
increased arch width as was previously
thought. www.indiandentalacademy.com
59. Shapiro AJO-1974
Mandibular intercuspid width
demonstrated a strong tendency to
return to its pre Rx dimension in all
groups except cl II, div 2.
Mandibular arch length decreased
substantially in every group during
post- retention period.

60. Gardner , AJO-1976
Inter cuspid width was expanded
during Rx but had a strong tendency to
return to its original pre Rx width in
both ext & nonext cases.
Inter I pm width showed the greatest
Rx increase in width with only a minimal
post Rx reduction
II pm width for nonext cases showed a
significant increase with slight tendency
for post- retn decrease.www.indiandentalacademy.com
61. II pm width for ext cases showed a
decrease with Rx & a slight continued
decrease post- retention
Inter molar width
Non ext cases –increase in width with Rx
Extraction cases – decrease with Rx
Post retention - no change

70% of the dental arches returned
to their original shape during the post
Rx period.

63. Patients pre Rx arch form
appeared to be the best guide for
future arch form stability.
De La Cruz et al, AJO 1995
Arch form tended to return toward
the pre Rx shape after retention & that
the greater the Rx change, the greater
the tendency for post- retention change.

64. CONCLUSION
The search for an ideal arch form, suitable
for every patient, has been an unrealistic
goal because of the wide individual variation.
The basic principal of arch form in
orthodontic Rx is that within reason, the
patients original arch form should be
preserved.
Retention should certainly be an important
consideration when original arch form is
changed during Rx.www.indiandentalacademy.com
