The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
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.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
1. Evolution of technique
Primary edgewise
*as described by Angle in 1929
*fully banded technique-gold bands ,soldered soft
brackets
*flat ideal arch wire -to provide normal occlusion
*original arch was of .022 X .028 in.gold wire
*to be adapted passively to all malocclusion
*if space had to be made ,loops are soldered onto
main arch
*if space closure required , spurs & tie backs used
*involves all the teeth to be brought under control
so,treatment should be initiated after eruption of
canine & premolar
www.indiandentalacademy.com
3. Secondary edgewise
*to avoid the making archwires passive
*use of round wires in the initial stages
*gold was replaced by a more rigid alloy
*frequency of extractions increased
*bands with prewelded brackets
*in 1940s round .045in.tubes were also soldered on
the upper molars for a face bow
www.indiandentalacademy.com
5. Tertiary edgewise or Tweed’s edgewise
*stressed on the importance of anchorage
preparation
*advocated the use of cl. III elastics & extraoral
traction
*vigorous forces were now employed
*space closure was done by simple vertical or
horizontal open loops bent into the archwire or by
push coil tie -backs
www.indiandentalacademy.com
6. Tweed’s philosophy
Based on the following :-
a) Practically all malocclusions are characterized by a
forward adjustment of teeth in relation to their basal
bones --- this is due to deficiency between the
basal bone & tooth material
b) The establishment & maintenance of a stable
anchorage should be the initial concern of the
operator & is a fundamental factor in successful
orthodontic treatment
c) Teeth like inanimate objects ,best resist the force of
displacement when tipped to the angulation that
offers the most advantageous mechanical against
the pull of dislodging forces .they are best stabilized
when they overlie the basal bonewww.indiandentalacademy.com
7. d)Teeth are most readily moved when their property &
power of mechanical resistance has been primarily
reduced
e) All forces emanating from an orthodontic appliance
must be synchronized if they are to be most effective
in the mass stabilization or the mass movement of
teeth
f) Nature being an expert mechanic herself ,offers
biologic compensations & adjustments when teeth
are placed in position of mechanical advantage for
force resistance
g) The dental units will best resist forward displacement
when the buccal teeth are in mild distal axial position
& the incisor teeth are in mild lingual axial inclination
& overlying a substantial bony foundation
“placing the incisors on the ridge”
www.indiandentalacademy.com
8. Every malocclusion exemplifies a denture that is
stabilized by balanced muscular forces & this
muscular balance must be preserved in treatment if
stability in the end result is to be accomplished
( Strang & Thompson )
www.indiandentalacademy.com
9. Facial types
Tweed divided the facial types into following
types:-
TYPE A :-Maxilla & mandible show forward &
downward growth
-ANB angle remains the same
-Prognosis is good
-Treatment not indicated during mixed
dentition if ANB angle does not exceed 4.5
TYPE A Subdivision:- ANB angle greater than 4.5
www.indiandentalacademy.com
10. TYBE B :- Maxilla & mandible grow downward &
forward with maxilla growing more rapidly
than mandible
- When ANB angle is 4.5 or less
prognosis is favorable
- Extraoral appliances should be
used immediately after extraction
TYBE B Subdivision :- ANB is large & found to
be increasing
-Undesirable growth trend,
treatment long & difficult
www.indiandentalacademy.com
11. TYPE C :- -Maxilla & mandible grow downward &
forward with mandible growing more than
maxilla
-ANB increasing
-Growth is favourable & treatment is
facilitated by growth
TYPE C Subdivision :- mandible grows more than
maxilla but only to a little extent
www.indiandentalacademy.com
12. Tweed’s Diagnostic facial triangle
Basis for diagnosis & treatment planning
Consists of the following :-
1) FMA –the Frankfort mandibular plane
angle
2) IMPA –the incisor mandibular plane
angle
3) FMIA – the Frankfort mandibular incisor
angle
www.indiandentalacademy.com
14. Angle FMA IMPA FMIA
Visual 25 90 65
cephalometric 24.57 86.93 68.20
Range 15 – 36 76 – 99 56 – 80
For successful treatment triangle should be attainable
Aim should be to obtain:-
FMIA of 70° – 75° ( when FMA = 20 )
FMIA of 65° ( when FMA = 30)
When FMA is less than 20° -
FMIA should be more than 70° & IMPA should not
exceed 94°
www.indiandentalacademy.com
15. He showed that in well balanced faces – IMPA was
90°±5°
For every degree that FMA was in excess of 25° .the
incisor mandibular angle IMPA would have to be
decreased by 1°
Treatment objectives :-
Facial balance & harmony
Stability of the post treatment dentition
Healthy oral tissues
Efficient mastication
www.indiandentalacademy.com
16. Anchorage preparation
Stable anchorage –important to prevent forward movement of
mandibular denture when cl.II intermaxillary force is applied
On histological basis Brodie (1937) believes that the strongest
anchorage is provided by stable fixation of teeth –to allow as
little movement as possible
Tweed – anchor teeth best resist the dislodging forces when their
vertical axes are parallel to the direction which offers the most
advantageous mechanical resistance against the pull of
dislodging forces
www.indiandentalacademy.com
17. Strongest anchorage is provided by tipping back the crowns of the
teeth so that they will have a disto-axial inclination that will resist
a forward pull
First & most important step in treatment - Anchorage preparation
If anchorage preparation is not done -the action of intermaxillary
elastics cause elevation of terminal molars & depression of
mandibular incisors.
Thus,canting of occlusal plane,
increase in FMA ,
point B drops downward & backward ,
entire mandibular denture is tipped & displaced forward into
protrusion
www.indiandentalacademy.com
18. Classification of anchorage preparation
First degree- minimal anchorage preparation,
-applicable to all malocclusion with ANB =0
to 4 ,
-total discrepancy does not exceed 10
mm,
-terminal molars must be uprighted & or
maintained in an upright position to
prevent their being elongated when cl. II
intermaxillary force is used .
www.indiandentalacademy.com
19. Second degree-for malocclusions with ANB more than
0° to 4°
-facial esthetics requires to move point
B anteriorly & point A posteriorly i,e
cl. II cases
-usually accompanied by type A, type A
subdiv.,type B & type B subdiv.
-degree of distal tipping of mandibular
molars more severe than first degree
anch.prep. –they should be tipped so
that their distal marginal ridges are at
gum level
www.indiandentalacademy.com
20. Third degree –severe discrepancy cases –14-20mm or
more
-ANB does not exceed 5°
-generally cl.I bimaxillary cases
-sliding jigs are necessary
-2nd
,1st
molars & 2nd
premolar must be
tipped to such an extent that the distal
marginal ridges are below the gum level
also called total anchorage preparation

21. Ideal arch form-
orthodontic arch is the form
which moulds the dental
arch with every bend
reflected in the position of
the teeth
Angle “ if an archwire is placed
in brackets with uniform slot
depths,it must take the form
of the outline of the buccal &
labial surfaces of the teeth”
Unique alignment of upper
lateral incisor –thinner labio-
lingually & short crown
length

22. Contact points lie on an ellipsoid curve
There is a straight line from canine to mesio buccal
cusp of first molar,but the beyond that it curves
inward progressively
Bonwill-Hawley diagram is widely used to decide arch
form

23. Bonwill-Hawley diagram is widely used to decide arch
form
General pattern –decided by studying the original
models & of the muscle behavior of the patient rather
than based upon widths of teeth themselves

24. Three orders of tooth movement
Movements necessary to bring the teeth into the line
of occlusion –first ,second ,third orders
First order bends-
-horizontal change relative to the line of occlusion
-also called in -out bends
-do not alter the horizontal plane of the wire
-the action & reaction of these bends affect
expansion or contraction
-used to move individual teeth
-the interaction of bends can affect the third order
position of the teeth if expansionary forces are used
www.indiandentalacademy.com
25. Second order bends
-represent a vertical
change
-also called
tip/angulation
-used to tip posterior
teeth mesially or
distally-may be
tip back or tip forward
bends
www.indiandentalacademy.com
26. Third order bends
-torsional change (with the line of occlusion
serving as axis)
-also called torque or inclination movement
-used to obtain axial changes in the bucco-
lingual or
labio-lingual root & crown axis on one or
more teeth
There are two types of torque
1)passive
2)active

27. Tweed summarised his philosophy on which his
appliance therapy is based:-
i) Normal occlusion is best maintained with the mandibular
incisors in their normal axial inclination when related to the F-H
plane approx. 65°(FMIA)
ii) The ultimate in balance & harmony of facial esthetics is
achieved only when the mandibular incisors are positioned over
the basal bone
iii) The normal relationship of the mandibular incisors to their
basal bone is the most reliable guide in diagnosis & treatment
of cl. I ,cl. II &bimaxillary protrusion cases and also in
attainment of balance & harmony of facial profile & permanence
of tooth position

28. General plan of treatment
Treatment divided into 3 phases:-
a)Anchorage preparation
b)Distal enmasse movement of maxillary buccal
segments
c)Establishing correct denture form & completing
treatment objectives
Anchorage preparation involves:-
1) placing mandibular incisors upright
2) changing axial inclinations of the maxillary incisors,
to make them less resistance to distal movement
3) changing the axial inclinations of buccal teeth to a
more distal axial inclination

32. Distal movements of canines & incisors
U/L .019 X .025 archwires with second order bends &
open coil springs compressed mesial to canines are
inserted
cl. III elastics aid in distal movement of mandibular canine
Headgear applied to upper arch aids in upper canine retraction
www.indiandentalacademy.com
33. Incisor retraction
Using .019 X .025 archwire with closed Bull loop distal
to canine –activated 1mm every 3 wks.
Mandibular incisors are retracted to an FMIA of 65° in
cl.I cases & 70° in cl.II cases
Maxillary incisor retraction completed –heavier .021 X .
027 in.wire ,reduced posterior to lateral incisors &
passed free of canine
Strong lingual root torque in upper anteriors for bodily
retraction

37. cl. II div.1 –non-extraction treatment
Preparation of anchorage in the lower arch
Preparation of anchorage in the upper arch
Distal enmasse movement of maxillary arch
Detailed positioning of teeth
ANCHORAGE PREPARATION
Initial leveling & alignment - .016 or .018 round wires
Working arch wire .019 X .025 in. with coordinated tip
back bends
cl. III intermaxillary hooks soldered mesial to canine
Loop stops are made mesial to molar tubes but the
archwire not tied to molar anchor teeth
www.indiandentalacademy.com
38. Upper arch is stabilized -.021 X .028 in.wire with mild tip
back bends
Intermediate pull headgear mesial to canine is used to
augment the anchorage - min. 14 hrs./day
Distal pull by headgear –twice as much as mesial pull
on the arch by cl. III elastics
During day – light cl. III
During night –heavy cl. III
Distal tip back bends increased slightly every 2-3 wks.
www.indiandentalacademy.com
39. Stabilization arch -.021 X .028 in. wire with same
degree of tip back bends as in working archwire
Passive in mandibular incisor region
Total time required – aprrox. 4 mons.
Anchorage preparation in upper arch
Excessive inclination of the proclined upper incisors is
reduced by using .018 in. round wire
Important – this provides unfavorable stationary
anchorage & resist distal / lingual movement of the
teeth
Heavy stabilization wire with mild second order bends is
placed
www.indiandentalacademy.com
40. Enmasse distal movement of maxillary arch
Upper arch wire -.021 X .028 in. reduced distal to
lateral incisors
Mild lingual crown torque if incisors are proclined
Intermaxillary hooks on archwire –patient put on cl. II
elastics
Watch out for mandibular anchorage –any signs of
mobility ,increase the tip back bends
After 3 wks. –tip back bends in the maxillary arch are
increased ,stronger elastic force is applied until
normal relation of teeth attained
Mild palatal root torque in anteriors
Continue till incisors in edge –edge relation & posteriors
in good occlusion
www.indiandentalacademy.com
41. Detailed positioning of teeth
Proper seating of cusps is obtained by fitting correlated
U & L ideal arches carrying vertical spurs for vertical
elastics between them
www.indiandentalacademy.com
42. Bimaxillary dentoalveolar protrusion
Two types of cases:-
1)Axial inclinations of all the teeth in the arch inclined
abnormally forward (both in cl.I & cl. II cases ),
Dental arches are more or less well aligned
2) Axial inclinations of teeth in buccal segments fairly
upright ,irregular & crowded
Steps in treatment:-
Anchorage preparation in lower arch
Anchorage preparation in upper arch
Extraction of four premolars
Multiple loops .016 in. archwire U/L used for
alignment
Space closure done using looped archwirewww.indiandentalacademy.com
43. Treatment of cl.III malocclusion
Objective:-
1)To correct abnormal buccolingual inclination of all
posterior teeth in both arches
2)Constrict the mandibular arch which is too broad
3)Expand the maxillary arch which is too narrow
4)Move maxillary arch forward enmasse ,using
mandibular arch as stationary anchorage
www.indiandentalacademy.com
44. Steps in treatment
Initial .016 in. round wires
After 2 wks. ,.021X .027 in. U/L ideal arches
Brass wire hooks mesial to canine
Mandibular archwire is bent considerably narrower than the ideal &
torque is placed in the buccal segment
Step forward 2nd
order bends placed in maxillary posterior segment
(direct opp.of tip back bends)
Intermaxillary elastics from lingual of maxillary molar to hook
mesial to mandibular canine
When cross bite is corrected –archwires are reshaped to the ideal
Treatment continued until the maxillary teeth have moved forward
enmasse into occlusion with teeth in mandibular arch.
