The document discusses the history and evolution of fixed orthodontic appliances, leading to the development of the pre-adjusted edgewise appliance. It describes Lawrence Andrews' research which identified six keys to optimal occlusion based on measurements of untreated dental casts. His studies found that traditional edgewise appliances did not achieve optimal occlusion in most treated cases. This led to the concept of a fully programmed pre-adjusted edgewise appliance that would incorporate his findings on natural tooth morphology and positioning.
The document discusses Ronald Roth's modifications to the Andrews Straight Wire Appliance philosophy and treatment approach. Roth started using the Andrews appliance in 1970 and later modified the bracket prescription based on his clinical experience. Some key differences between Andrews and Roth include Roth allowing more tipping of teeth initially and building overcorrection into the brackets to account for relapse. Roth also placed more emphasis on achieving a gnathological occlusion goal versus Andrews' focus on anatomical tooth positions. The document outlines Roth's bracket placement, prescription, and rationale for his modifications to the straight wire appliance.
This document discusses various techniques for intruding teeth in orthodontics. It begins by defining intrusion and describing how it differs from other tooth movements like tipping. Deep overbites can be corrected through intrusion of anterior teeth or other movements. The principles of intrusion mechanics include applying light continuous forces through the center of resistance and using devices that create statically determinate force systems. Various intrusion appliances are described, including utility arches, tipback springs, continuous and segmented intrusion arches. Key biomechanical concepts for intrusion like controlling reactive forces and avoiding extrusion are also summarized.
Dr. Percival Raymond Begg developed the Begg technique for orthodontic treatment over many years, beginning in the 1920s. He studied under Dr. Angle and was an early user of the Edgewise appliance. Through his own practice, Begg realized some limitations of Angle's methods and made modifications like removing teeth or stripping tooth width to improve outcomes. This evolved into the Begg technique using light wires and brackets to minimize forces and reduce relapse. The technique gained popularity after visits by American orthodontists to Begg's practice and demonstrations of its effectiveness.
Orthodontic tooth movement during space closure can occur through two types of mechanics: segmental/sectional mechanics which do not involve friction, and sliding mechanics which do involve friction between the bracket and archwire. Friction plays a significant role in sliding mechanics. Several methods are used to apply force during space closure, including elastomeric modules, elastomeric chains, and closed coil springs made of materials like stainless steel and nickel titanium. These methods vary in terms of factors like force degradation over time and sensitivity to environmental factors like temperature. Maintaining an optimal force during retraction is important for controlled tooth movement.
Self-ligating brackets have an in-built metal face that can open and close. They were developed to address issues with conventional ligating systems like high friction and impaired oral hygiene. Self-ligating brackets are classified as active or passive based on whether their clip actively engages the archwire. Key advantages include improved engagement, lower friction, faster treatment, and better oral hygiene. However, several studies found no difference in treatment time or outcomes compared to conventional brackets. Clinical tips for using self-ligating brackets include longer appointment intervals, more use of lighter forces early on, and an initial wire sequence of 0.014" then 0.014"x0.025" nickel titanium.

Maxillomandibular elastics (or intermaxillary elastics) are commonly used because of their simplicity; however, a lack of understanding of their force system can lead to many serious problems.
Elastics are usually classified by the direction of the force (eg, Class II or Class III elastics).
Sometimes force magnitude is considered, but point of force application is left out. Therefore, many different types of Class II elastics can be applied. There are short or long elastics.
Often too many elastics are used when a single resultant elastic at the correct location would work better. However, sometimes more than a single elastic is needed when the attachment point is not directly accessible.
All maxillomandibular elastics and their actions should be analyzed in three dimensions.

Use of modified tooth forms in complete denture occlusion / dental implant...Indian dental academy
This document discusses dental occlusion concepts and philosophies for complete dentures. It introduces key terms like physiologic occlusion and defines different occlusion schemes like balanced articulation and monoplane articulation. The document discusses advantages and disadvantages of using anatomic versus non-anatomic teeth for complete dentures. It also outlines requirements for maintaining denture stability, such as balanced occlusal contacts and control of horizontal forces. The goal of occlusion for complete dentures is to re-establish the homeostasis of the masticatory system disrupted by edentulism.

4. Stage II Records.
Points to be evaluated:
1) Bite opened.
2) Edge to edge incisor contact.
3) All rotations, anterior and posterior properly
overcorrected.
4) Molar relationship overcorrected.
5) Good, well supported intercuspal posterior
occlusion.
6) All space closed.
7) Buccolingual relationship of posterior teeth
properly established.
8) Anterior teeth sufficiently retracted to allow for
some relapse.
www.indiandentalacademy.com
5. STAGE III
OBJECTIVES:
1. Maintain all corrections achieved
during first and second stages.
2. Achieve desired axial inclinations of
all teeth.
www.indiandentalacademy.com
6. Pre-stage III archwire..
The highly resilient 0.016 inch archwires
should be used in gaining bicuspid bracket
engagement preparatory to the placement
of the heavier and less resilient 0.020-inch
stage III archwire.
This precaution avoids the imposition of
excessive alignment forces on the
bicuspid teeth.
www.indiandentalacademy.com
7. Maxillary base arch wire
0.020-inch round stainless steel Australian heat-
treated arch wire is used.
Purpose -: 1}Maintening proper dental arch
form.
2}Maintaing bite-opening that has
been obtained.
3}Stabilizing(counteracting)
against adverse reciprocal forces.www.indiandentalacademy.com
8. Intermaxillary hooks.
-Located 1mm mesial
to each canine
bracket.
-Formed with middle
step of Tweed’s loop-
forming pliers. (2mm
diameter)
-Ligation of hooks to
canine brackets www.indiandentalacademy.com
9. Anchor bends.
Reduced or removed?
Archwire should just touch the mesial
opening of the buccal tubes at 6 o’ clock
position without exerting tipping action.
www.indiandentalacademy.com
10. Molar horizontal offset.
-Because of difference in the buccolingual
dimensions of the molars and premolars.
-To place the central developmental
grooves of the teeth in alignment.
Placed 1-2mm mesial to the molar tubes.
www.indiandentalacademy.com
11. Occlusal blend (vertical step-up bend).
-Mesial to the molar tube.
- To obtain bicuspid bracket engagement
-Maintain correct vertical molar-premolar
relation.
Change in the marginal ridge height thatChange in the marginal ridge height that
will accompany uprighting of a mesiallywill accompany uprighting of a mesially
tipped premolar should be taken intotipped premolar should be taken into
consideration.consideration.
www.indiandentalacademy.com
13. ‘V’ bend ( Gingival bend, Accessory bite
opening bend)
Slight (about 15 degrees) ‘V’ bend distal
to canines in the base archwire which will
bow the incisal section of archwire
gingivally.
Extent should be sufficient to bring the
anterior section of archwire to the level of
gingival margin of the central incisors
when the archwire is seated in the molar
tubes and premolar brackets.
www.indiandentalacademy.com
16. Reciprocal actions of canine and
premolar uprighting springs?
Resultant openbite in the canine premolar
area. www.indiandentalacademy.com
17. Reciprocal action of incisal torquing
auxillary?
Resultant deepening of overbite in central
incisor area. www.indiandentalacademy.com
18. ‘V’ bend will produce an intrusive force on
central incisors and and a slight extrusive
force on canines and premolars, thus
compensating distorting forces.
Maintain the bite-opening achieved in
earlier stages.
www.indiandentalacademy.com
19. The posterior section of the base archwire
is constricted.
Molar portion of the base archwire should
lie on the tips of lingual cusps of molars
when the archwire is held over the
occlusal aspect of dental arch to
determine arch form.
Care about expansion or constriction of
canines? www.indiandentalacademy.com
20. To counteract the widening effect of
incisor torquing auxillary i.e to counteract
the untoward moments resulting from
activation of incisor torquing auxillary
which tips the molars buccally.
www.indiandentalacademy.com
22. If molar intrusion occurs it can be
controlled by the use of vertical elastics
between the maxillary and mandibular
molars.
www.indiandentalacademy.com
23. Bending archwires around tubes.
Distal tips should be annealed to the level
of distal of molar buccal tube.
Wire is cut off 2mm distal to molar buccal
tube and free end is bent so that it rests
against the molar band occlusally to the
molar tube.
-Serves to maintain space closure.
www.indiandentalacademy.com
25. Care to be taken to prevent the beaks of
pliers from resting against the distal
surface of the tube.
-Can set up a camming action that results
in the archwire being drawn distally
through the molar tube with such force
during bending that the archwire can be
permanently distorted in the inter-maxillary
hook area. This can destroy the desired
archform and permit the anchor molars to
move buccally. www.indiandentalacademy.com
26. The bend should be barely snug against
the distal end of tube.
Cinching back the ends of archwire tightly
cause molar expansion and disto-buccal
molar rotation.
www.indiandentalacademy.com
27. Lingual ligatures.Lingual ligatures.
Described by Dr. Raleigh Williams.
Made of 0.012-inch ligature wire.
Tied to molar and pulled anteriorly
through the cervical embrasure between
lateral incisor and cuspids and is twisted
around the archwire.
www.indiandentalacademy.com
29. Should be used to maintain space closure
and hold corrected molar rotation.
Should be snug but never tight.
www.indiandentalacademy.com
30. Excessive tightening of this ligature tends
to distort archform by flattening the
archwire in the area of circle hook and
may cause proximal binding which may
interfere with uprighting.
www.indiandentalacademy.com
32. Intermaxillary hooks.
Intermaxillary hooks are located 0.5mm mesial
to each canine bracket.
Formed with first step of Tweed’s loop-forming
pliers. (1mm diameter)
Small rings occupy less archwire space between
the canine and lateral incisor brackets thereby
providing more space for the horizontal arms of
the lateral incisor uprighting springs.
Ligation of hooks to canine brackets.
www.indiandentalacademy.com
33. Slight (about 10 degrees) ‘V’ bend distal
to canines in the base archwire which will
bow the incisal section of archwire
gingivally.
As heavier base archwire is used, anchor
bend reduced than in earlier stages to
prevent distal tipping of molars.
Molar horizontal offset and vertical step.
www.indiandentalacademy.com
34. Expanded at its end to combat the
continued tendency for the mandibular
anchor molars to tip lingually from the
wearing of class II elastics.
www.indiandentalacademy.com
35. Mesio-distal Uprighting spring (Individual
root-spring)
Original uprighting spring with long lever
arm and tail.
www.indiandentalacademy.com
36. Refinement of the original spring.
-Shorter lever arm.
-Larger, more resilient coils.
-As efficient as original spring.
-The angulation of the active arm
and retentive arm is 135 degree.
Advantages: self retaining and being short they
do not interfere with springs on adjacent teeth.
www.indiandentalacademy.com
37. Self retaining uprighting spring with 3 full
coils to provide gentle, continuous force
necessary to upright teeth without
requiring reactivation.
www.indiandentalacademy.com
38. Placed in the pin channels of the
brackets.
Helix should wind in the lingual direction
i.e towards the tooth surface and lie on the
gingival aspect of the archwire at the
opening of the bracket slot.
www.indiandentalacademy.com
39. Length of the hook is made slightly
greater than the diameter of the helix to
keep arm of spring parallel to the archwire
in the vertical plane.
To avoid the rotating force on the tooth,
the arm of the spring is offset buccally to
make it parallel to the archwire in the
horizontal plane.www.indiandentalacademy.com
41. Action of short arm uprighting spring.
www.indiandentalacademy.com
42. Long-arm uprighting springs.Long-arm uprighting springs.
-Used when mesiodistal diameters of canine and
premolars are small where it is not possible to
place the short-arm type of uprighting springs
without the hooks contacting each other.
www.indiandentalacademy.com
43. Inherent Problem?
When the uprighting springs are engaged
and under tension, the coils press against
the gingival edge of the bracket. If the
archwire is not safely tied into the slot in
the bracket, this force from the coil can
cause the bracket to move away from the
archwire, with a subsequent elongation of
the tooth.
www.indiandentalacademy.com
44. Solution?
Spring-pin.Spring-pin.
- combination of lock-pin and and an uprighting
spring.
The leg of the pin portion passes lingual to the archwire,
and the tail of the spring fits labial to the archwire in the
space in the space in the bracket slot, and the tooth is
free to upright mesiodistally with no danger of it being
elongated.
Eliminates the need for ligating the arch wire to the
bracket www.indiandentalacademy.com
45. Spring-pin is inserted in bracket with the
pin portion passing lingual to the archwire.
www.indiandentalacademy.com
46. Annealed end of spring is bent around the
incisal end of bracket, securely locking the
spring-pin and archwire in place.
www.indiandentalacademy.com
47. Arm of spring is hooked over the archwire,
activating the coils and creating the
necessary force to upright the tooth
mesiodistally.
www.indiandentalacademy.com
48. The horizontal arms of the uprighting springs
may need to be shortened as uprighting occurs
to prevent space opening, tooth rotation, and
impairment of the uprighting action which may
result from contact of the hooks with the
adjacent brackets or bands.
www.indiandentalacademy.com
49. The degree of activation of the uprighting
spring depends on
1) Size of wire.
2) Diameter of the helix.
3) Number of turns in the helix.
4) Length of the arm of the spring, and
5) Size of the root of the tooth being
uprighted.
www.indiandentalacademy.com
50. In a first premolar extraction case:
Order for need of teeth to be uprighted:
Lower canines
Upper canines
Lower second premolars
Upper second premolars
Upper lateral incisors
Lower lateral incisors

52. Upper and lower canines-0.016-inch or
0.018inch, 2- coils
Upper and lower second premolars- 0.016
inch , 2- coils
Upper lateral incisors – 0.014 inch,2- coils
Lower lateral incisors – 0,014 inch ,3-
coils
www.indiandentalacademy.com
53. Most resilient available wire should be
used (Australian heat-treated
stainless steel) because:
1) Makes possible the engagement of the arm of
the spring about the archwire, with little chance
of deformation.
2) Insures full activation of the springs during a
greater range of uprighting.
3) There is less need to reactivate the arms of
springs to insure continuous uprighting of teeth.

60. Originally spurs to rest against the labial
surfaces of upper central and lateral
incisors were bent into the main maxillary
archwire made from 0.016-inch archwire
material.
The effect was to move the molars
buccally and also to rotate them disto-
buccally.
www.indiandentalacademy.com
61. By employing a heavier main base
archwire in conjunction with a torquing
auxiliary bent from lighter material (0.014
to 0.016-inch), it was possible to prevent
undesired movement of the maxillary
anchor molars.
www.indiandentalacademy.com
62. Four-Spur torquing auxiliary.Four-Spur torquing auxiliary.

63. Factors which alter the forceFactors which alter the force
values of an auxiliary:values of an auxiliary:
1) Type of wire
2) Diameter of the wire
3) Size of the circle
4) Angle the spur makes with the plane
of the auxiliary
5) Axial inclination of the teeth
6) Length of the spur?
www.indiandentalacademy.com
64. The amount of torque force is related to the
extent that the spurs are tipped back, the
torque force being derived from the amount of
torque in main line of auxiliary archwire.
The spurs play a passive role- they act
only as means of delivery of torque force
from the main line of archwire.www.indiandentalacademy.com

www.indiandentalacademy.com
70. Activated by meeting the resistance of the
stop on the midline of the archwire.
Possible to remove torque bars from the
lateral incisors as these teeth become
adequately torqued.
Can be modified to produce labial root
movement.
www.indiandentalacademy.com
71. Procedure for assembling a Stage III
mechanism:
1} Place the upper and lower main base
archwires in the mouth.
2} Lower archwire is pinned in place,
using Stage III lock-pins on teeth that do
not require mesiodistal uprighting.
3} Place proper spring pins in all
remaining mandibular teeth and maxillary
second premolar brackets.
www.indiandentalacademy.com
72. 4} Pin the upper torquing auxiliary in one
of the maxillary central incisor brackets.
5} Distal ends of auxiliary are then pinned
into canine brackets gingival to main
archwire with spring-pins.
6} Bend the distal ends of the archwire as
described earlier.www.indiandentalacademy.com
74. Additional considerations:Additional considerations:
If the maxillary or mandibular anchor molars
show signs of rotating distobuccally, tie with
0.012-inch diameter ligature wire lingually from
lingual hook on molar to lingual button on
cuspid.
The end of archwire should not be bent tightly
around the distal surface of molar tube here, as
molar tube must be free to slide distally to allow
the molars to rotate distolingually.

75. TWO SPUR TORQUING AUXILIARYTWO SPUR TORQUING AUXILIARY
( von der Heydt auxiliary )( von der Heydt auxiliary )
When only central incisors reguire the
torque, auxillary with two spurs is used.
www.indiandentalacademy.com
76. Maxillary lateral incisors are often displaced
bodily to the lingual prior to the treatment.
During stages I and III, their crowns are tipped
labially, leaving their roots far to the lingual.
Unless their roots are torqued labially during
stage III, their crowns will tend to relapse
lingually .

88. Conclusion.Conclusion.
-One needs a lot of perseverance to reach
proficiency in this technique.
-Various refinements and modifications in
the Begg technique have given the
orthodontists innumerable ways of
achieving the objectives of the procedure.
-We as Orthodontists should go ahead
and put them to judicious and profitable
use. www.indiandentalacademy.com
90. Sequence of insertion of Archwires
and Auxiliaries
The base arch wires are inserted
unpinned but fitting well upto the Begg slot
Arch wires are cinched distal to the
molars to prevent the spaces from
opening up
Depending on the need for torquing the
torquing auxiliary is fabricated
www.indiandentalacademy.com
91. In the lower arch only uprighting
springs are inserted unless labial/lingual
torque is needed
direct the lower arms towards the root
movement intended
insert the vertical leg into the pin slot
pull it occlusally so the spring lock
holds the archwire firmly
bend this vertical leg towards the root
movement intended
to activate hook the lever arm to the
main archwire.www.indiandentalacademy.com
92. After the root tipping movements of the
third stage are completed remove the
torquing and paralleling auxiliaries and
make adjustments in the base archwire
to complete the treatment.
To flatten the occlusal plane make
localized vertical offset bends to level
individual teeth
To obtain bilateral symmetry make
definite localized horizontal offset bends
to expand or contract individual teeth
and make the arch symmetrical
www.indiandentalacademy.com
93. INDIVIDUAL TORQUEING AUXILIARYINDIVIDUAL TORQUEING AUXILIARY
Used for selected upper or lower teeth
Auxiliary should extend at least one tooth pass
tooth being torqued, and around curve of arch, for
maximum activation.
If placed gingivally, torque the root of the lateral

98. The lingual torquing effect is on account of two
factors:
1. Vertical plane changes to horizontal.
2. Smaller circle opens to large.
Both these effects force the tips of the
spurs to press in a lingual direction against the
gingival portion of the crown. Reciprocally, the inter –
spur spans of the auxiliary tend to lift away in a labial
direction. Thus a force couple is created. The labial
forces are resisted by the bracket slots and the base
archwire to which auxiliary is tied this accentuates the
action of root lingual moving force.
