1) The Herbst appliance is a fixed functional appliance that produces a forward positioning of the mandible through a telescopic mechanism attached to orthodontic bands.
2) It stimulates mandibular growth and inhibits maxillary growth, resulting in distal movement of the upper teeth and mesial movement of the lower teeth to correct class II malocclusions.
3) Short term effects include overcorrection of the occlusion and vertical changes like intrusion of lower incisors, but long term stability of the class I occlusion is achieved through stable cuspal interdigitation after post-treatment adaptations.

Utility arches are auxiliary archwires used for orthodontic tooth movement. They are commonly made of blue elgiloy wire and engage the back four teeth (two molars) and front four teeth (incisors), so they are also known as 2x4 appliances. There are different types of utility arches for various tooth movements, including intrusion, retraction, and protrusion. Intrusion utility arches have a step cut anterior to the molar tube to allow slight tooth retraction while intruding incisors with a force of 25 grams per tooth. Adjustments are made intraorally using dental pliers.

The document discusses the third stage of the Begg technique for orthodontic treatment. Stage III focuses on correcting the axial inclination of teeth through root tipping using torquing auxiliaries and uprighting springs. It maintains the corrections from stages I and II while achieving the desired mesiodistal and labiolingual inclinations of each tooth simultaneously. Stiffer base archwires and various auxiliary appliances like torquing bars and uprighting springs are used to tip roots into their proper positions while keeping crowns relatively stationary. The document provides details on the design and function of these appliances to achieve the treatment objectives of stage III.

Fixed functional appliances / /certified fixed orthodontic courses by Indian ...Indian dental academy
The document discusses fixed functional appliances used to treat malocclusions. It focuses on different types of Herbst appliances, which are fixed bite jumping devices that keep the mandible in an anterior forced position. The original Herbst appliance from 1900 had telescopic parts made of metal attached to crowns on molars and premolars. Later modifications in the 1970s used bands and involved different anchorage methods. The modern Herbst typically uses cast metal splints covering all buccal teeth. It works full-time to alter mandibular position and correct Class II malocclusions without patient removal.
The document discusses various scars and potential negative effects that can result from orthodontic treatment. It covers effects on teeth such as enamel demineralization, enamel cracks, root resorption, and pulp damage. Supporting structures like gingiva, alveolar bone, and the temporomandibular joint can also be negatively impacted. Specific issues from rapid palatal expansion, extraction treatment, debonding procedures, and relapse are described. The document emphasizes using light continuous forces to minimize harm and informing patients of risks.

This document provides information on using infrazygomatic crest implants (IZC) for orthodontic anchorage. It discusses the history, anatomy, dimensions, indications, placement sites and guidelines for IZC. Case examples demonstrate using a self-drilling IZC screw for asymmetric distalization of the maxillary arch to correct a dental midline. Placement of the IZC screw allowed for full arch distalization without complex appliances. The treatment resulted in a Class I molar and canine relationship bilaterally with an improved dental and soft tissue profile. Complications and failure rates of IZC are also reviewed.
This document discusses various types of intrusion arches used in orthodontics to correct deep overbites. It begins by defining intrusion and describing the biomechanics and principles involved. It then covers 9 specific intrusion arch designs: 1) Rickett's Utility Arch 2) Tipback Springs 3) Burstone's Continuous Intrusion Arch 4) Burstone's Three Piece Intrusion Arch 5) K-SIR 6) Connecticut Intrusion Arch 7) PG Retraction Spring 8) Translation Arch 9) Lingual Arch for intruding lower incisors.

This document provides guidelines for proper orthodontic bracket placement. It discusses positioning brackets on both the upper and lower dental arches. For the upper arch, it recommends placing maxillary second premolar brackets slightly more anteriorly to facilitate proper rotation into occlusion. It also advises ignoring the lingual cusp of asymmetric premolars when determining bracket placement. For the lower arch, it suggests placing mandibular premolar brackets more gingivally to avoid occlusal interference. Improperly positioned brackets can result in poor tooth alignment, longer treatment times, and less than ideal occlusion.

Functional appliances utilize the natural forces of the orofacial musculature to produce skeletal and dental changes. They are based on Moss's functional matrix theory which proposes that muscles and glands influence bone growth. Functional appliances can be active or passive and produce orthopedic, dentoalveolar, and muscular changes through forces of compression, elimination of restrictive influences, and mandibular repositioning. Common functional appliances discussed in the document include Bionators, Twin-Blocks, Herbst, Frankel Regulator, and Jasper Jumper. They vary in their mode of action, indications, advantages, and disadvantages.

Functional appliances are either active or passive devices that harness the natural forces of muscles in the mouth and face to guide growth of the jaws and teeth. They work based on Moss's functional matrix theory, which proposes that muscles and other soft tissues influence bone growth. Common functional appliances include the activator, bionator, frankel appliance, and twin block. They can modify jaw growth, alter tooth positions, and improve muscle tone. Functional appliance therapy is most effective when started before puberty to influence jaw growth.
The document summarizes research on various fixed appliances for managing Class II malocclusions:
1) Studies on the Xbow appliance found it resulted in mild maxillary restriction, dental effects of upper incisor palatal tipping and lower incisor labial tipping, and no significant skeletal effects on the mandible.
2) A study comparing the Xbow and Forsus appliances found they produced similar amounts of incisor inclination but the Forsus resulted in greater lower incisor proclination.
3) Research on the Forsus Fatigue Resistant Device (FRD) demonstrated it can effectively camouflage Class II malocclusions through maxillary restriction and dental effects like upper
This document provides an overview of bioprogressive therapy, which uses a systematic approach to diagnose and treat malocclusions. It discusses principles like treating overbite before overjet, sectional arch therapy, and using proper forces. It covers topics like orthopedics, forces used, triple control appliances, mixed dentition treatment, and finishing procedures. The goal of bioprogressive therapy is to efficiently achieve quality results using prefabricated appliances while following principles of torque control and using cortical and muscular anchorage.

Controversies in early orthodontic treatment /certified fixed orthodontic cou...Indian dental academy
This document discusses controversies in early orthodontic treatment. It begins by defining early treatment as treatment initiated during the primary or mixed dentition stage to enhance dental and skeletal development before the permanent dentition erupts. While early treatment was initially controversial, it is now accepted that some malocclusions benefit from early intervention. The document examines controversies surrounding the timing of treatment and two-phase vs one-phase treatment. It also discusses evidence for and against early treatment of class II malocclusions. The overall conclusion is that one-phase treatment starting in the late mixed dentition is sufficient for most patients.

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
9
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.
4. A skeletal Class II - fault with the maxilla
www.indiandentalacademy.com
5. A skeletal Class II - fault with the mandible
www.indiandentalacademy.com
6. A skeletal Class II - fault with the mandible
www.indiandentalacademy.com
7. Correction of Class II malocclusion – An
Enigma
• Dilemma regarding –
•
•
•
•
Age to initiate ?
Modality of correction
What to expect ??
How to retain ??
www.indiandentalacademy.com
8. Contributors to Class II malocclusion
• Maxillary prognathism – 30%
• Mandibular retrusion - 70%
----Mc’Namara (1981)
Mastorakos study( 1984) --- slight disagreement with
Mc’Namara’s values
www.indiandentalacademy.com
9. Earlier dictum in Growth modulation
• Start treatment early for Class II correction ; hold
the correction for a longer period.
• Distinct European and American strategies
• Complete second phase of treatment with fixed
appliances
www.indiandentalacademy.com
10. Problems with two-phase treatment
• Excessively long duration of treatment
• Burn-out of patient co-operation
• No additional benefits to majority of patients
compared to those undergoing a single phase of
treatment
• Less cost-effective
www.indiandentalacademy.com
11. Timing of Class II correction
Based on RCT’s done in US and UK, Proffit states
• “ Early treatment for most Class II children is
no more effective and considerably less efficient
than later one-stage treatment during
adolescence” - AJODO 2006
www.indiandentalacademy.com
12. Wrong assumptions made..
• Class II correction in mixed dentition does not
work well
• Start Class II correction only in permanent
dentition
• What about cases with severe proclination??
• What about psychological benefits to those
Class II children who are bullied due to their
protruding teeth?
www.indiandentalacademy.com
13. The present view
• Two-phase treatment may make the
treatment
unnecessarily
prolonged
;
economics and co-operation levels difficult to
justify
• Therefore a single phase of treatment gaining
widespread acceptance.
www.indiandentalacademy.com
14. CONSIDER A PROTOCOL BASED ON:
• Growth status of the patient,
• State of dentition,
• Nature of dental malocclusion (irregularities)
needing pre-functional corrections,
• Whether the patient will need any extractions,
• Amount of incisor exposure.
www.indiandentalacademy.com
15. Growth status of the patient
• Optimum timing for growth modulation of
Class II (irrespective of treatment modality) is
the active growth period coinciding with the
pubertal growth spurt
– Sassouni 1972
– Pearson 1978
– Pancherz 1985
– Malmgren 1987
– Baccetti 2000 etc
www.indiandentalacademy.com
16. • Mandibular growth is slightly behind the
skeletal growth (Fishman and others).
• Hence, the ideal timing for growth modulation
would be during or slightly after the peak of
the growth spurt.
www.indiandentalacademy.com
17. Assessment of the Peak of Growth Spurt
• Earlier method was the hand and wrist
radiograph (or MP3)
2 ½ years
www.indiandentalacademy.com
6 ½ years
11 years
19 years
19. • The one phase treatment cases could be
classified, based on their growth status, into:
a. Early (CVM I – Growth spurt peak will occur
after more than 1 year),
b. Appropriate (CVM II– peak will occur within
few months),
c. Late (CVM III – spurt has already occurred,
or beyond).
www.indiandentalacademy.com
21. Weigh the following
• Predisposition to trauma
• Psychological assessment
•Problem areas – Skeletal, dental or both?
•Any transverse /vertical problems?
www.indiandentalacademy.com
22. Cases ideal for early intervention
• Patients with severe deficit of mandibular
growth.
• Cases with severe proclination/ psychological
insult
• Cases with excessively narrow maxilla
• Class II intervention by way of habit correction
www.indiandentalacademy.com
23. Is amalgamation of fixed appliances
and functionals acceptable?
“Concurrent usage of fixed appliances and
functional therapy does not spell a biologic
compromise; instead it may offer a
mechanical advantage”
–T.M Graber
www.indiandentalacademy.com
24. Shifting paradigms in Class II
treatment
Concept of Telescoping treatment
Coupling two modalities of treatment to
extract maximum benefit of both in a
shorter time.
Also aim at minimising side effects of each
other
www.indiandentalacademy.com
25. Telescoping treatment
for Class II malocclusions
• Combining
benefits
of
mandibular
advancement while minimising side effects on
dentition.
• Help in augmenting sagittal and transverse
corrections
• Minimise overall treatment time

29. THE METHOD OF OPERATION OF
FUNCTIONAL APPLIANCES
functional appliance
Increased contractile activity of the LPM
Intensification of the repetitive activity of the retrodiscal pad
(Bilaminar zone)
Increase in growth stimulating factors
Enhancement of local mediators
www.indiandentalacademy.com
30. Reduction of local regulators
(factors having negative feed back
effects on cell multiplication rate)
Changes in condylar trabecular orientation
Additional growth of condylar cartilage
Additional sub-periosteal ossification of the
Posterior border of the mandible
Supplementary lengthening of the mandible
THE METHOD OF OPERATION OF
FUNCTIONAL APPLIANCES
www.indiandentalacademy.com
31. Advantages of fixed functional appliances
over removable functional appliances
• less dependent on the patient co-operation
• works 24 hrs a day, so there is continuous
stimulus for mandibular growth
• Treatment time is short (approx 6 – 8 months)
• Direction of force is more constant
• smaller in size permitting better adaptation
www.indiandentalacademy.com
32. CORRECTION OF CL II MALOCCLUSION
• Dento alveolar changes
• Restriction of forward growth of the mid face
• Stimulations of mandibular growth beyond that
which would normally occur in growing children.
• Redirection of condylar growth –
upward & forward directed growth to posterior
direction
www.indiandentalacademy.com
33. • Deflection of ramal form
• Horizontal expression of mandibular growth
from downward and forward to horizontal.
• Changes in neuromuscular anatomy and
function that would induce bone remodeling.
• Adaptive changes in glenoid fossa location to a
more anterior and vertical position.
www.indiandentalacademy.com
34. Classification of Fixed Functional
Appliances
• According to Antonio Korrodi Ritto
– Rigid Inter-maxillary Appliances (RIMA)
– Flexible Inter-maxillary Appliances (FIMA)
– Hybrid Appliances (Combination of RIMA & FIMA)
www.indiandentalacademy.com
35. Classification of Non-compliance
Inter-maxillary Appliances
According to Moschos A Papadopoulous
– Rigid Inter-maxillary Appliances (RIMA)
– Flexible Inter-maxillary Appliances (FIMA)
– Hybrid Appliances (Combination of RIMA & FIMA)
– Appliances acting as substitutes for elastics

119. Conclusion
• qualities that functional appliances should
have:
– Patient comfort and acceptance are excellent
– promote better compliance
– offer an extensive range of motion
– simple and inexpensive
– Easy to fit
– adaptable to either Class II or III
www.indiandentalacademy.com
120. Conclusion
– be used for mandibular positioning or dentoalveolar
movement
– cause less breakage of archwires and appliances and
thus fewer emergency appointments
– Inventory requirements are minimal . The appliance
can be used on either side of the mouth and there is
only one size
– used at any stage of treatment mixed or permanent
– low profile results - considerably less buccal irritation
– produce good results without the need for patient
cooperation
