Various appliance systems have
evolved in the field of
orthodontics,which claimed it’s own
advantages with inherent
disadvantages.Few appliance systems
emerged as a variant of the existing
appliance systems.
Few emerged as a result of combination of
two appliance systems.
One example for such a appliance
system is TIP_EDGE.

E.H Angle ,father of orthodontics,
introduced edgewise brackets in the
year of 1925. The major
disadvantage of edgewise brackets
was ,it had no provisions to
facilitate the closing of spaces in
the posterior segments.
His best suggestion to tip crowns
distally was the use of second order
bends in the archwire.

Since the death of E.H Angle in the year of
1930,there was no refinements in this system
to overcome this problem. And in-fact this
problem continued till the era of straight wire
appliance.
Strang suggested placing the vertical
loops in the edgewise archwire to create
space in the buccal segments.

Dr. P.R.Begg, an Australian
employed, modified ribbon arch
brackets to design his appliance,
which permitted free mesiodistal
tipping of the teeth.
Begg employed Auxillaries to
upright the teeth (uprighting
springs), and to root torque the
teeth.

Begg died in the year of 1983, still
searching for a way to achieve final,
positive three dimensional control from
a ribbon arch –type of bracket for the
deferential technique (crown tipping
followed by controlled root up-righting).
In the subsequent years there appeared
various modifications in the Classical
Begg technique namely,

The ideal bracket should offer the ease of
manipulation inherent in edgewise
brackets including a labially facing arch-
wire slot and ligation with elastomeric
rings.

It should also permit crown tipping and
subsequent root up righting using
auxiliaries in conjunction with relatively
stiff, passive, round arch-wires.
Predetermined tip and torque control
should be available, when required,
through rectangular arch-wires or
auxillaries.

The tip-edge bracket makes all the above
possible and permits differential tooth
movement with straight arch-wires,And
therefore, carries the name “Differential
Straight Arch Technique”.

Tip-Edge Concept.
The Tip-Edge concept is to provide
an edgewise type bracket that is
familiar to all orthodontists and can
be used in the simplest manner
imaginable to treat all malocclusions
through differential tooth movement.

Each tooth tips distally- except those
distal to extraction sites.Anchor molars
should remain upright throughout
treatment. Differential bite opening
(quickly and from light,intra-oral forces)
is only possible if the anterior teeth are
free to tip in all directions as they are
free to tip in all directions as they are
depressed.

The Tip-Edge bracket has been designed
to provide all the benefits and advantages
of differential tooth movement plus
predetermined degrees of final crown tip
and torque.
Lateral extensions (wings)on the bracket
provide maximum rotational control even
when the tooth is tipped. Therefore, the
bracket body can be narrow for maximum
esthetics. The wings, which are lingual to
the arch wire , are virtually invisible.

and II.

brackets with wings. Double width bracket.
Ceramic bracket. Stamped Tip-Edge bracket.

Each bracket has a vertical slot to
accept rotating or up-righting springs,
Power pins, and Jigs for accurate
direct bonding. The vertical slot is
0.020”x0.020” square with both the
gingival and incisal ends chamfered
to facilitate the insertion of
Auxiliaries from either directions. It
can also be used to accept a ligature
on the lingually placed tooth.

The horizontal arch wire slot is .
022”x.028”and has the exciting,though
generally un appreciated, feature of
increasing in vertical dimension as the
crown tips. (up to 0.028”)
This permits stepping up to larger size
arch wires with no flexing or bending.
(from 0.016” to 0.022”)

Advantages of Tip-Edge brackets:
1.Chamfered edges minimizes the
anchorage strain and permits the
desired distal crown tipping
required for differential tooth
movement.
2.Pre adjusted in three dimensions,
the Tip Edge slot permits the use of
straight arch wires in the majority
of the cases both extraction and non
extraction.

3. The slot is designed so that initial
second order changes, mesio-distal
crown tipping, can be accomplished
in the presence of a straight, round
arch wire and powered by a light intra
oral forces, elastic or coil springs.
Forces for subsequent root up
righting, tip and/or torque are
generated by auxiliaries, not by
flexing the arch wires.

4. Tip edge brackets are available in
single, twin or ceramic versions to
meet the preferences of all
Orthodontists.
5. Not only do the arch wire slots
permits initial crown tipping but also
they are pre-adjusted to provide the
desired final degrees crown tip and
torque.

6. Anchorage problems associated with
previous straight wire brackets should be
completely eliminated as spaces can be
closed with relatively light forces and
minimal arch wire deflection. Six or more
teeth can be retracted by crown tipping
more easily than two are moved bodily.
This results in diminished anchorage
demands and increased vertical control.
With differential tooth movement anchor
molars are not subjected to forces great
enough to initiate their movement until
spaces are closed.

The in/out compensation built in to Tip-
edge brackets eliminates the need for
molar offsets normally required when
using ribbon arch type brackets.(It is
now possible to treat patients using
differential forces and mechanics with
straight arch wires).

Horizontally facing arch wire slots facilitate initial
arch wire engagement especially on rotated teeth.
Elastomeric ties provide a degree of flexibility or
“cushion” that doesnot exist when using ribbon arch
type brackets and lock pins. This enhances patient
comfort and reduces the chancs for bond failures.

Also tip edge arch wire slots can stop free
distal crown tipping of canines at a
predetermined angle. This concurrently
increases anterior anchorage to encourage
the mesial movement of the posterior teeth
and is an example of programmed
differential mechanics at work.

 The Tip-edge bracket is dynamic in
action.
 The degree of individual tooth control it
exerts can vary throughout treatment.
This facilitates both appliance
manipulation and tooth movement.
 The progressively increasing control is
partly automatic because of the design
of the arch wire slot and is partly
selective due to the application of a
unique elastomeric Tip-edge ring, an up-
righting spring, and/or a rectangular arch
wire.

Tip-Edge brackets also ensures full vertical and
angular control during final up-righting and
torquing in the presence of 0.0215” x 0.028”
rectangular arch wires.
With the advent of nickel titanium arch wires
and auxiliaries there is no reason to reduce the
size of the arch wire slots to fit smaller
rectangular arch wires as a means of reducing
excessive torque and tip forces.

 Tip- Edge arch wire slots are pre-
adjusted, this makes possible a
revolutionary method of tooth movement-
from start to finish.
 When used on all teeth (except anchor
molar), they permit crown tipping and
susequent root up-righting using auxiliaries
in conjunction with relatively stiff,
passive, round or rectangular arch wires.

DIFFERENTIAL STRAIGHT ARCH TECHNIQUE
The differential straight arch technique(DSAT) is
designed to permit teeth toward their
anatomically correct positions in the jaws under
the influence of very light forces- as would occur
naturally in the presence of attrition. a unique
approach to orthodontic treatment.
Larger posterior teeth tend to slowly move
“Down Stream” throughout life with the currents
of mesial migration. Rapid, distal movement of
smaller anterior teeth is possible with the
application of light forces in the presence of
round arch wires and brackets that permit distal
crown tipping.

Premolar Tip-Edge brackets:
-Both maxillary and mandibular first and second
premolars are having zero degree of tip .
-Maxillary premolars are having –7o of torque.
-Mandibular premolars are having –20o of torque.
Adnantages:
1. It is possible to reduce bracket inventories and have
just two maxillary and two mandibular premolar
brackets.
2. These brackets can then be switched from right to left
(not from maxillary to mandibular) to provide
clockwise and counter clockwise crown tipping
according to the needs of each case.www.indiandentalacademy.com

Premolar Tip-Edge brackets:

positioning Jigs ensure proper arch wire levels in
relation to incisal edges and cusp tips. Bracket
placement charts suggesting heights and corresponding
jig colors are available.

Molar tubes:
Molar attachments for differential tooth
movement are designed to keep the
molars upright yet permit free sliding of
the arch wire. This is necessary to
facilitate retraction of anterior teeth from
light (2 ounce, 56.70 gm) forces.

Three types of molar tubes are available depending on the
operators preferences and the requirement of the case.
1. Single round molar tube.
2. Combination edge-wise and round tube, and
Combination edge-wise and flat oval tube(used for
double back arch wires).
3. Tip-Edge convertible tube.

Tip-Edge rings:

Straight shooter ligature gun:
Secure the arch wire in
position and by pressing
the trigger the ring is
released.

The “hammock effect:
When a ligature, either steel or elastomeric, is used to
retain an arch wire in a tip-edge bracket, a “hammock”
effect is created.
This effect tends to maintain the existing mesio-distal tip
relationship between the arch wire and the bracket.

Rotation springs:
Rotation springs provide an easy means of rotating
teeth without removing the arch wire. Pre formed
springs made of 0.014” round Australian wire inserted
from gingival vertical slot will cause the rotation of the
teeth.

Power pins:
Ideal auxillary for engaging removable
elastics or any type of fixed elastomeric.
Unlike ordinary power hooks, power pins are
optional and may be inserted in to the
vertical slot from the incisal or gingival or on
any bracket at any time. Can be inserted or
removed while both the arch wire and
ligature remain in place.

Mesio distal up-righting spring (side winders)
Made up of 0.014” Australian wire for clock wise or

superior. Engaged in the vertical slots from the incisal to
prevent deformation of the coils due to occlusal force.

The Outrigger Appliance:
Provides an excellent means of ensuring
class II or Class III elastic wear. If elastics
are not worn the hooks extend labially in to
uncomfortable positions. When elastics are
engaged the hooks swing incisally in to
much more comfortable positions.

Nickel titanium Torque Bars:
Used to torque the incisors to their final inclinations.
These Auxiliaries are formed with 30 degrees activation
and are virtually invisible when engaged since they lie
directly behind the arch wire.

Treatment:
Treatment is divided in to three stages
Each stage features a distinct set of treatment
goals that must be achieved before moving on to
the next.
Specific arch wires and auxiliaries are employed
during each stage.
Mixing the goals or the use of improper arch
wires and auxiliaries can lead to excessive
anchorage loss, compromised control of the
vertical dimension, and other undesired
complications. www.indiandentalacademy.com

Goals of stage one:
1. Vertical correction of deep or anterior
open bite.
2. Horizontal correction of anterior over
or underjet.
3. Align anterior teeth to eliminate
crowding or spacing.

Stage I

Goals of stage two:
1. Close remaining posterior spaces.
2. Correct or maintain dental midlines.
3. Correct posterior cross bites.
4. Achieve class I molar relation.
5. Over correct severely rotated premolars.
6. Level anchor molars(if tipped distally).
7. Maintain all corrections achieved during
stage I

Stage II

Goals of stage three:
1. Achieve final inclinations of all teeth.
2. Maintain all corrections achieved
during stages one and two.

To conclude it would be better to say that
tip edge technique amalgamates the
advantages of Begg Lightwire technique
with that of the Edge-wise technique, and
gives the free hand to those practitioners
who are trained in Begg technique so as to
make them flexible to use contemporary
ideas. Thus this technique makes all
possible movements that is achieved by
straight wire technique and Begg
technique.
