This document discusses molar distalization, which is an alternative method for gaining space when treating orthodontic patients with space deficiencies. It provides the history of molar distalization, indications and contraindications for its use, different appliance options, and considerations for appliance selection. Molar distalization involves using orthodontic appliances to distalize or move the molars backwards in the dental arch in order to gain space.
This document provides an overview of molar distalization techniques. It discusses the history and development of appliances used for molar distalization, including headgear, K loops, and pendulum appliances. Key points covered include indications and contraindications for molar distalization, diagnostic criteria, treatment timing, and the two phase treatment approach - the initial space gaining phase followed by a consolidation phase.
The Carriere Distalizer is a direct bond appliance used to correct Class II malocclusions. It distally moves the maxillary posterior segments as a unit from canine to molar while also correcting upper first molar rotation and uprighting over an average treatment time of 3-4 months. The non-invasive design and self-expressed movements result in high patient compliance and a Class I occlusion outcome.

This document discusses several methods for distalizing maxillary and mandibular molars, including removable appliances, fixed appliances, and surgical techniques. For maxillary molars, common removable appliances discussed are the Cetlin appliance, acrylic cervical occipital appliance, and a removable appliance using screws and springs to simultaneously distalize and expand the arch. Fixed appliances can use coils or TMA to distalize molars. For mandibular molars, it is more difficult and extraoral appliances are rarely used; common intraoral options include lip bumpers and lingual arches. Surgical extraction of impacted teeth may also be required to create space for molar distalization.
Removable appliances for molar distalization include extra-oral traction with headgear and removable appliances with finger springs or sliding jigs. Headgear can be divided into cervical, occipital, and combination types based on the location of force application. Cervical headgear applies force below the occlusal plane to produce distalization and eruption, while occipital headgear applies force above the plane for distalization and intrusion. Combination headgear allows control of force levels and direction. Headgear is effective but may cause unwanted tooth movement so selection depends on the patient's malocclusion and growth pattern.

This document discusses current trends in molar distalization. It begins by explaining that orthodontic treatment philosophies now aim to avoid extractions and rely less on patient cooperation, leading to development of various appliances for distalizing maxillary molars. Removable appliances include headgear and finger springs, while fixed appliances include intra- and intermaxillary devices like pendulums, magnets, and coils. Factors like second molar eruption and skeletal patterns influence distalization. A proper diagnosis is needed to determine if distalization is indicated based on growth prognosis and sagittal relationships. Contraindications include high mandibular planes and open bites.

Skeletal anchorage provides more effective molar distalization with less anchorage loss compared to conventional anchorage. A meta-analysis of intraoral distalization studies found that skeletal anchorage methods resulted in greater amounts of molar movement with no loss of anchorage when using direct skeletal anchorage. Both anchorage methods resulted in effective distalization but conventional anchorage was associated with undesirable side effects like anchorage loss and premolar tipping.
This document provides information about molar distalization, including:
- Molar distalization involves moving molars backwards to correct malocclusions.
- Various appliances can be used for molar distalization, including headgear, K-loops, and pendulum appliances.
- Treatment planning for molar distalization generally involves two phases - a space gaining phase followed by a consolidation phase to achieve ideal occlusion.
This document summarizes information presented at a seminar on molar uprighting. It discusses factors that can influence uprighting a molar tipped into an extraction site, including extraction timing, periodontal condition, vertical dimension, number of missing teeth, position of the third molar, and condition of the alveolar ridge. It also reviews appliances that can be used for molar uprighting, including principles of anchorage and attachments, and techniques for uprighting a single molar with or without extrusion. The document provides details on final positioning of the molar and premolars after uprighting is completed.
The document discusses the treatment philosophy of Tweed-Merrifield Edgewise appliance which includes 5 concepts: 1) sequential appliance placement, 2) sequential tooth movement, 3) sequential mandibular anchorage preparation, 4) directional force including control of vertical dimension, and 5) proper timing of treatment.

A magnetic resonance imaging studyof the temporomandibular joint and the disc...Abu-Hussein Muhamad
Causative correction of skeletal malocclusions is achieved through bite–jumping by various means. Numerous animal experiments yielded evidence of rebuilt temporomandibular structures after mandibular protrusion. However, the mode and extent of structural and/or topographic changes of the disco-condylar relation after functional orthopaedic treatment is still an issue at stake. A problem exists in defining the physiologic (centric) position of the condyles and the proper disco-condylar relation which is tentatively determined by various methods particularly in MRI studies. Despite the high resolution provided, the results have to be interpreted with caution, as osseous resorption and apposition can not be assessed by visual evidence. In this article a prospective study is presented which proves the effectiveness of the “Wuerzburg concept“, i.e. bionator plus extraoral traction and up-and-down elastics, and its impact on the temporomandibular joint. The underlying reactions are studied by means of MR images obtained from sucessfully treated patients.

This study compared the anchorage provided by the Nance appliance (NA) and fixed frontal bite plane (FBP) during intra-arch distal molar movement over 6 months in 40 patients. Both groups experienced approximately 1.4-1.9mm of anterior movement of the maxillary central incisors, with no significant difference between groups. Distal molar movement was 1.7-1.8mm in both groups. The overbite decreased more in the FBP group. Neither appliance provided fully stable anchorage. A second treatment phase is recommended to correct anchorage loss after distal molar movement.
Asymmetric maxillary expansion (AMEX) appliance for treatment of true unilat...Indian dental academy
This document describes a study on using an asymmetric maxillary expansion (AMEX) appliance to treat true unilateral posterior crossbites. The AMEX provided significant expansion of the maxillary arch width on the crossbite side, moving the maxillary teeth buccally, while limiting expansion on the non-crossbite side. Measurements from pre- and post-expansion models and radiographs showed the crossbite side teeth moved buccally more than the non-crossbite side teeth. Some buccal crown tipping of the maxillary posterior teeth occurred due to the force point being below the resistance center, which could reduce anterior overbite. The AMEX was effective for correcting unilateral posterior cross

The aim of this retrospective study was to cephalometrically evaluate and compare the skeletal and dental effects of a transverse sagittal maxillary expander (TSME) and a Hyrax-type expander (RME) in children with maxillary hypoplasia. Fifty subjects were divided into two groups, one treated with a TSME and the other with a RME. Cephalometric measurements before and after treatment showed that the TSME group had a statistically significant increase in anterior positioning of the maxilla and maxillary incisors, while the RME group saw an increase in upper molar positioning and total anterior facial height. The TSME was found to be more effective at producing skeletal changes and correcting max

This document discusses the classification, causes, and treatment options for Class II and Class III malocclusions. It begins with an overview of Class II malocclusions, including the dental and skeletal classifications. Common causes are discussed, such as heredity and environmental factors. Treatment options for Class II malocclusions include camouflage with orthodontics alone, extraction of premolars with orthodontics, and distalization of maxillary molars with appliances or temporary skeletal anchorage. Class III malocclusions are also briefly covered, discussing etiology, classification, and treatment including camouflage or surgical options.
The Twin Block Appliance is a functional orthodontic appliance consisting of upper and lower removable bite blocks used to correct Class II malocclusions by repositioning the mandible forward through inclined occlusal planes which provide proprioceptive stimulus for bone growth; it was developed in the 1980s as an improvement on previous functional appliances and provides numerous orthodontic, dental, skeletal, soft tissue and airway benefits when worn as directed.
orthodontic correction of canted occlusal plane part 4Maher Fouda
This document discusses the orthodontic correction of occlusal plane canting through several case studies. It begins by defining occlusal plane canting and how it can influence smile esthetics. It then describes two types of maxillary occlusal canting - Type 1 with a wavy occlusal plane but good tooth angulations, and Type 2 with total maxillary skeletal canting. The document presents several cases where occlusal canting was corrected through methods like segmental surgery, temporary anchorage devices, and orthognathic surgery. It concludes that occlusal plane canting can be successfully treated to improve smile esthetics.
Immediate effects of rapid maxillary expansion with haas-type and hyrax-type ...Dr. Carlos Joel Sequeira.
This randomized clinical trial evaluated and compared the immediate effects of rapid maxillary expansion (RME) using Haas-type and hyrax-type expanders through cone-beam computed tomography (CBCT) scans. 33 subjects were randomly assigned to either the Haas or hyrax group. Both groups underwent RME with 4 quarter turns of initial activation followed by 2 quarter turns per day until 8mm of expansion was reached. CBCT scans were taken before and after expansion. Measurements showed that both appliances significantly increased maxillary transverse dimensions, with greater skeletal than dental expansion. The hyrax group demonstrated greater orthopedic effects and less tipping of maxillary molars compared to the Haas group, but the differences were less

The document discusses orientation jaw relation and facebow transfer procedures. It defines orientation jaw relation as establishing the reference in the cranium and the relationship between the maxilla and mandible. It then describes recording orientation using a facebow to relate the maxillary cast to the articulator in the same way the maxilla relates to the temporomandibular joints. The document also summarizes the types of facebows, including arbitrary and kinematic, and procedures for using each in complete dentures and fixed prosthodontics.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

1. Efficiency Of A Pendulum Appliance For
Molar
Distalization Related To Second And Third
Molar
Eruption Stage
WWW.INDIANDENTALACADEMY.COM
2. Correction of a Class II malocclusion without extractions
requires maxillary molar distalization by means of intraoral
or extraoral forces
WWW.INDIANDENTALACADEMY.COM
3. Although headgears have proven useful
in the correction of skeletal problems, as well as in
providing anchorage for extraction cases, they depend
heavily on patient cooperation
WWW.INDIANDENTALACADEMY.COM
4. Various fixed intraoral appliances for molar distalization
have been introduced, in avoiding undesirable
biomechanical
side effects.
WWW.INDIANDENTALACADEMY.COM
5. In the 1970s, Bernstein described the ACCO (acrylic
resin cervico-occipital) appliance, a cross between the
removable plate-type appliance with pendulum springs
and cervical or occipital headgear
WWW.INDIANDENTALACADEMY.COM
6. In the 1980s, the Wilson appliance
(Rocky Mountain Orthodontics, Denver, Colo) was introduced
in which the molars are distalized via compression springs,
thus requiring the patient to wear Class II elastics to prevent
the loss of anchorage.
WWW.INDIANDENTALACADEMY.COM
7. The active elements of the pendulum appliance are pendulum springs
inserted palatally into the molar bands.
WWW.INDIANDENTALACADEMY.COM
8. The Pendulum appliance appliance, first described in 1992
by Hilgers, was later modified by him and others, including
Snodgrass
Byloff et al,
Favero,
Grummons, Scuzzo et al, and
Kinzinger etal.
WWW.INDIANDENTALACADEMY.COM
9. Ideal Intraoral Molar-distalization Appliance
Should Meet The Following Criteria
• Minimal need for patient compliance.
• Acceptable esthetics and comfort.
• Minimal loss of anterior anchorage (as evidenced
by axial proclination of the incisors).
• Bodily movement of molars to avoid undesirable
side effects, lengthening of treatment, and
unstable results .
Minimal chairtime for placement and reactivations
WWW.INDIANDENTALACADEMY.COM
10. According to studies by Byloff et al,Bussick and
McNamara,Ghosh and Nanda, and Joseph and Butchart,
the position of the second molar when distalizing the first
molar with a pendulum appliance is of little if any
importance .
The aim of the present study was to assess this
hypothesis
WWW.INDIANDENTALACADEMY.COM
11. A modified pendulum appliance for bilateral molar
distalization was fixed in the maxillae of 36 patients (25
girls, 11 boys; mean age, 12 years 5 months).
The dentition in the anchoring complex was identical (with
the appliance fixed to the 4 premolars), the patients were
divided into 3 groups, according to the stage of second and
third molar eruption
WWW.INDIANDENTALACADEMY.COM
12. Group 1(PG:1): Bilateral distalization of first molars; second
molars on both sides not yet erupted.
Group 2(PG:2): Bilateral, simultaneous distalization
of first and second molars with third molar at budding stage.
Group 3(PG:3): Simultaneous distalization of first
and second molars on both sides, with germectomy of third
molars.
WWW.INDIANDENTALACADEMY.COM
13. In PG 1 (18 patients), eruption of the second molars had either notyet
taken place or was not complete.
In PG 2 (15 patients), the second molars had already developed to the
occlusal plane with the third molars at the budding stage.
In PG 3 (3 patients), third-molar germectomy had been completed, and
eruption of the first and secondmolars was complete.
WWW.INDIANDENTALACADEMY.COM
14. The pendulum appliance is pendulum K, used in this study is
a modification of the standard pendulum appliance
according to Hilgers. The appliance includes a distal screw
dividing the Nance button into 2 sections.
WWW.INDIANDENTALACADEMY.COM
15. The anterior section provides anchorage, and the posterior
section accommodates
the pendulum springs
WWW.INDIANDENTALACADEMY.COM
16. These pendulum springs are not only activated for distalization (as an approximate
guideline 180-200 centinewtons [cN]). Additionally applied is a built-in
straightening activation and toe-in bending.
The appliance is activated intraorally by the therapist at the checkup appointments
by adjusting the distal screw; there is no need for the pendulum springs to be
disengaged from the lingual sheaths
WWW.INDIANDENTALACADEMY.COM
17. Molar movement in the horizontal plane was monitored
by taking alginate impressions and making dental casts both
at the outset of therapy (T1) and after removal of the
pendulum appliance (T2).
WWW.INDIANDENTALACADEMY.COM
18. . The measurements were to identify in each
patient group any increase or decrease in transverse
arch width in the region of the first and second molars
as well as the magnitude and mode of molar rotation
achieved by the therapy

20. Measurements were taken of the distance from the lowest
point in the central fossa to the mesiobuccal a distobuccal cusp tips of the
first and second molars for change in tranverse dimension .
The angles between the straight line transversing the mesiobuccal and
distobuccal cusp tips and the raphe-median line weretaken for checking molar
rotation

● m1/SN, angle between first maxillary molar and anterior cranium floor
● m2/SN, angle between second maxillary molar and
anterior cranium floor
WWW.INDIANDENTALACADEMY.COM
25. To check for any vertical changes, the angles between the
anterior cranium floor and the alveolar point (SNA), between
the anterior cranium floor and the palatal plane (SN/ANSPNS),
and the angles of the facial axis, facial plane, mandibular plane,
and lower facial height, were measured.
WWW.INDIANDENTALACADEMY.COM
26. In the sagittal plane, relative mesial incisor movement, loss
of anchorage, and relative distal movement of the first and
second molars to the vertical of the pterygoid were
measured
(i-CEJ/PTV, m1-CEJ/PTV, m2-CEJ/PTV).
WWW.INDIANDENTALACADEMY.COM
27. The degrees of labial incisor and distal molar tipping
were determined by measuring the angles between
the longitudinal tooth axis and the palatal plane and
the anterior cranium floor, respectively.
WWW.INDIANDENTALACADEMY.COM
28. In the vertical plane, any intrusion or extrusion of the first
molars in relation to the palatal plane was checked (m1-
SZG/ANS-PNS). The baseline for these measurements was the
cementoenamel junction on the longitudinal tooth axis.
WWW.INDIANDENTALACADEMY.COM
29. In the horizontal plane, dental cast measurements for the 18
patients in PG 2 and PG 3 (in whom the distalization effect of
the pendulum spring on the first molars extended to the
already erupted second molars) showed not only mesiobuccal
rotation of both maxillary molars but also vestibular drift of
the unbanded second molars
WWW.INDIANDENTALACADEMY.COM
30. In the 3 patients of PG 3, in whom germectomy of the
wisdom teeth had already been completed, the increase in
transverse arch width was average.
The possible factor behind the phenomenon of vestibular drift
( clearly not depending on the third molars) might be the morpholog
of the molars and the contact point regions, the relative position of
the molars to each other, or the anatomically fixed position of the
spongiosa groove.
A third molar bud seemed to place no restriction on the degree of
vestibular drift.
WWW.INDIANDENTALACADEMY.COM
31. In the sagittal plane, cephalometric analysis for
identifying any changes showed that, in the
distalization direction, a tooth bud acts on the mesial
neighboring tooth in the same way as a fulcrum
WWW.INDIANDENTALACADEMY.COM
32. In sagittal plane, tooth bud in direction of distalization acts like fulcrum on its
mesial neighbor. Degree of tipping of first molars was much greater in patients
whose second molars were still at budding stage
WWW.INDIANDENTALACADEMY.COM
33. Degree of tipping of fully erupted second molars was still greater when
third molar was located in direction of movement. In contrast, distalization
of first molars was almost completely bodily.
WWW.INDIANDENTALACADEMY.COM
34. After third molar germectomy, almost completely bodily distalization of
both molars is possible, even when second molars are left unbanded.
WWW.INDIANDENTALACADEMY.COM
35. Biomechanical analysis
(approximation)
When the lingual sheath of the molar band is acted
on by a force FP (due to pendulum spring activation), a
torque MP, resulting from the product of the force FP
and the vertical distance to the center of resistance of
the molar, simultaneously arises.
WWW.INDIANDENTALACADEMY.COM
36. Horizontal plane
In the horizontal plane, a distobuccal torque, MP, results from the force of the
pendulum spring FP acting on the lingual sheath of the molar band at the first
molar (thus palatal to the center of resistance of that tooth). The magnitude of
this torque, although present, is extremely small and can be ignored for clinical
purposes. The direction of the force FP
depends directly on the path of the circular arc
described by the pendulum spring.
WWW.INDIANDENTALACADEMY.COM
37. The closed loop is positioned at the center of rotation of the pendulum
spring distal from the center of resistance and
With the activation of the distal screw taking place at the zenith of the arc
impact the distally directed line of force and the force-torque ratio in the
lingual sheath
WWW.INDIANDENTALACADEMY.COM
38. Up to the zenith of the circular arc, the force FP due to the pendulum spring can be
broken down into 2 vectors, 1 acting distally, the other vestibularly. The resulting line
of force acts in the distovestibular direction
This direction of in the region of the lingual sheath, has the same direction and
impact as would result from toe-in bending.
This is in the mesiobuccally directed torque Mti on the first Molar), which acts in
opposition to the distobuccal torque MP..
WWW.INDIANDENTALACADEMY.COM
39. An additional toe-in-bend applied directly to the pendulum spring
amplifies the corresponding torque in a therapeutically desirable way.
The net effect is that the first molar is subjected to the desired expansion
and distalization, together with mesiobuccal rotation. Deviation in the
orovestibular direction is avoided
WWW.INDIANDENTALACADEMY.COM
40. Because of the rhomboid shape of the molar crown, the mean mesial
rotation of the first molars (as determined by the study) and the
approximal surface running diagonally from mesiobuccal to distopalatal
net movement of the second molar is both distal and buccal.
WWW.INDIANDENTALACADEMY.COM
41. Sagittal plane
In the sagittal plane, a distinction must be made between the
force systems involved in the 3 different stages of the dentition:
For the second molar at the budding stage.
When eruption of the second molar is complete and a third molar
bud is located distal to.
Second molar when the eruption of the first and second molars is
complete and no third molar bud is present (missing, germectomy).
WWW.INDIANDENTALACADEMY.COM
42. The force FP applied to the first molars with
thependulum spring acts coronal to the center of
resistance, a resulting torque MP acts simultaneously
on the molars.
In the zone of contact between the first and second
molars, a second molar at the budding stage produces
a counterforce FK, in opposition to the distalization
force FP. At static equilibrium, both forces are of the
same magnitude
FP =FK.
WWW.INDIANDENTALACADEMY.COM
43. The corresponding torque MK acts in parallel to
torque MP, and thus the 2 torques are summed. To
achieve maximum translatory first molar distalization
in this configuration, the sum of all torques needs to
have a magnitude of zero.
Ideally the torque MA arising from the straightening
activation should therefore be equal to the sum of
MP and MK
Straightening activation also produces an intrusion
force FA on the molars that acts in opposition to the
extrusion produced by the arc described by the
pendulum spring.
WWW.INDIANDENTALACADEMY.COM
44. When eruption of the second molar is
complete and a third molar bud is present:
At static equilibrium, the magnitude of the
distalization force FP is equal to the sum of
the magnitudes of the opposing forces acting
at the points of contact:
FP = FK +FK
WWW.INDIANDENTALACADEMY.COM
45. The line of force of the counterforce FK
produced by the second molar in the contact
point area runs approximately at the same
level as the line of force of the distalization
force FP. The resulting torque MK acts here in
opposition to the torque MP.
WWW.INDIANDENTALACADEMY.COM
46. To achieve maximum physical distalization of the first
molars, the straightening activation on the first molar can
be correspondingly weaker compared with the not yet
completely erupted second molar. This is because, in terms
of direction, the resulting torque MA is the same as the
torque MK and, acting together with it, should nullify
torque MP
Summation M at the first molar + MP +MA _+0
WWW.INDIANDENTALACADEMY.COM
47. The force conditions for the second molar are similar to
those applying in the first system to the first molar.
Torque MK’ is also directionally the same as torque
MP’. Because no straightening activation can be
applied to the second molar, there is no
therapeuticmeans of producing an opposing torque
Summation M at the second molar = MP’ _ MK’
WWW.INDIANDENTALACADEMY.COM
48. In conditions where the second molar when the eruption of the first and second molars
is complete and no third molar bud is present (missing, germectomy)The only force
acting at the distal alveolar crest of the second molar is a biological resistance due to the
periodontium. Thus, in this instance, the torque MP’ does not become large ;
Summation M at the second molar = MP’.
Unlike in the second system, although second molar distalization is not bodily in this case
either, there is
comparatively little tipping.
WWW.INDIANDENTALACADEMY.COM
49. CONCLUSIONS
For young patients, the best time to start therapy with a pendulum
appliance is before the eruption of the second molars
However, if distalization of the first and second molars is to be carried out
simultaneously (in which case the banded first molars are pushing the
second molars along during distalization), prior germectomy of the third
molar is strongly recommended. However, greater loss of anchorage and
vestibular drift of the second molar must be accepted
