MOLLENHAUR”S ALIGNING
AUXILLARY & ITS
 The

MAA attempts root control from the
very beginning, without significantly
affecting the anchorage and over bite
correction.
 The MAA is made from the 0.009”
Supreme grade wire.


 Requirements

for use of the MAA
 1 . It must generalte very light
moving forces.
 The adjacent rectangles must not
diverge by more than 45
 The auxillary must be able to resist
deformation- Supreme grade wire is
used.
 The base wire should be able to
resist the reciprocal forces.

 5.

MAA is engaged first and the main arch
wire is piggy back.

 Advantages

of the MAA
 1. Efficaci in intrusion and simulataneous
retraction of the anterior teeth.
 2.rapidly bodily alignment of the anterior
teeth.
 3. Stable results.
 4. Reciprocability of torquing forces on the
instandind laterals or palatally placed
canines.

 5.

Periodontal advantages.
 Short stage III.
 Various

applications of the MAA
 By bending more positive torque, it
can be used after the stage I as a
braking mechanism.
 Applying labial root torque on the
lower incisors in growing
brachyfacial cases to prevent their
roots from lingualizing.

mollenhauer can be used for
controlling the mesio- distal root
position.
 This application is called MAA- tip.


 Biomechanics

of the MAA.

 A.


Modified application of the MAA
 The

holding down the boxes for
lingual root torque with the tail end
of the lock pins was difficult.
 In this modification, the torque is
directly applied on the gingival
surface of teeth.
 It is made with the boxes inside the
circle.

 When

reciprocal root torque is
required, the box meant for labial
root torque rides over the main wire
and presses against the incisal
portion of the crown.
 MAA is not used for
unravellingcrowding. It is fitted only
after enough space is created by
distalizing the canines.


The torquing auxillary with spurs
 The

auxillary is made from 0.012”
premium Plus wire.
 Modifications:
 1. Length of the spur- the length of the
spur should be kept at least 5mm,
leaving it about 1mm short of the gum
to facilitate proper hygeine.

 2.

Inclination of the spurs to the
horizontal(occlusal) plane is kept 0.in other
words the activation is 100%.
 3. The angle of the spur from the inter spur
span opens up and the legs of the spur tend
to converge.
 This is remedied by slightly over angulating
the spur and by keeping it less divergent.
 The distal leg of every spur is kept slightly
shorter by about 0.5mm so that it does not
project incisally to the main archwire.


 4.

The inter spur span is curved as
recommended by Kesling.a straight or
angulated inter-spur span cannot
assume a perfect curvature.

 Correctly

made auxillary having curved
inter=spur span.


 Modifications

of torquing auxillary
 A. Reverse (lsbisl) torque on one or
both the lateral incisors: Boxes at right angle to the plane of the
spurs are made that lie at the incisal
area of lat incisors
 Crossover bends are made on either
side of the lateral incisor bracket to
permit the auxillary to pass over the
base wire

 B.

torquing boxes on the canines for
lingual root torque: Boxes can be provided
 The ends of the auxillary need not
extend beyond the canine area


Some other torquing auxillary
 1.

Single root torquing auxillary :
 it is useful design for any teeth except
molars.
 It is particularly indicated on upper
premolar


 2.reciprocal

torquing auxillary (SPEC)

design.
 It is employed when teeth require
torque in opposite directions.
 It is made in lighter 0.009” or 0.010”
size wire if uded in stage I & II
 If needed for the stage III it should be
made in 0.012”


 3.

Reverse torquing auxillary for
cntrolling the roots of canine or
premolars.
 Designed by Franciskus Tan in 1987
 It is used for labial root movement of
palatally impacted canine.
 For lingual root torque it is inverted.
 It is made from 0.012”P wire in
conjunction with 0.018” or 0.020” base
wire

 In

order to resist the palatal root torque
on the molar that arises as a reaction
from the auxillary the molars are
stabilized with the help of TPA.

 4.

Buccal root torque on the molars.an
additional auxillary made in 0.014” size
wire isfitted in a round molar tubes.
 It has boot design occlusal extensions
on the molars.

 The

auxillary need not be engaged in
other brackets.

 5.

Labial root torque only on the lateral
incisors: It is used for reducing the prominence
of the canine roots
 It is made from0.012” size arch wire

Uprighting springs in new
australian wires The

0.014” size wire was used earlier
but now 0.009” supreme grade wire is
used.
 Advantages Very light continious forces.
 Less taxation on the anchorage
 Ease in maintaining mouth hygeine and
better esthetics.

 The

new springs differ from the older
springs in the following respects The coil of the spring is only twice the
size of the wire; in contrast to the size of
the former springs that was 4 times the
wire diameter.
 The stem of the spring runs tangential
to the coil, unlike the previous springs in
which the stem was radial to the coil.


 1oo%

activation; the stem and active
arm are in one line ie making an angle
of 180 compared to the earlier 135
angulation


 Securing

the springs
 The ligature wire is passed through the
bracket in front of the archwireand then
passed behind the archwire outside the
bracket and the two ends are twisted
together.
 The ligture tied in this fashion will leave
just enough space for insertion of the
spring stem, thus ensuring a snug fit.


Size of the coil- Mini Maxi or
midi
 Newer

springs- mini springs
 Conventionasl springs- maxi spring
 The coil of the spring is very small.
 The coils can be made bigger by winding it
around the0.9mm spring winder tip.- midi
spring.
 These are generally made in 0.010” for
incisors.
 0.012” canines and premolars.

How to prepare a Spring winder?
2

pieces of wires are embeded in a cylindrical
acrylic handle
 One wire is kept at axial centre.
 The other is kept at the side of the main arch
wire.
 Both are seperated by a distance of aout
1mm.
 The diameter of the coil would be equal to the
diameter of this projecting wire.
