Tongue and its importance in orthodontic treatment /certified fixed orthodont...Indian dental academy
This document discusses the anatomy, development, functions and examination of the tongue. It notes that the tongue plays an important role in dental development and malocclusion through its pressures and posture. Abnormal tongue posture, like a forward resting posture, can exert pressures on teeth and affect their positions over time. The document examines tongue posture and functions like swallowing, and discusses conditions like tongue thrust and retained infantile swallowing that can influence malocclusion. Metric evaluation methods like cephalometry and palatography are presented for assessing tongue posture.

Headgears are classified based on their use, attachment method, and direction of pull. The key components of facebow headgear are described, including the outer bow, inner bow, junction, and force elements like elastics that connect it to the head cap or cervical strap anchorage. Adjustments to the inner bow are outlined to position the appliance properly during treatment.
Elastics and Elastomeric are routinely used as a active component of orthodontic therapy.
Elastics have been a valuable adjunct of any orthodontic treatment for many years.
There use combined with good patient cooperation provides the clinician with the ability to correct both
Antero-posterior and vertical discrepancies. The latex elastics have become integral part of orthodontics after being first discussed by Calvin. S. case in 1893 at the Columbia dental congress but the credit goes to Henry A. Baker for the use of these elastics in clinical practice to exert a class II intermaxillary forces.
Both natural rubber and synthetic elastomers are widely used in orthodontic therapy. Naturally produced latex elastics are used in the Begg technique to provide intermaxillary traction and intramaxillary forces. Synthetic elastomeric materials in the form of chains find their greatest application with edgewise mechanics where they are used to move the teeth along the arc
This document discusses utility arches, which are orthodontic appliances used to apply light forces in the dental arch. It provides details on:
- The historical background and development of utility arches based on biomechanical principles.
- Common wire dimensions and materials used, including stainless steel, nickel titanium, and beta titanium alloys.
- The standard design components of utility arches, including molar, vertical, and incisal segments.
- Different types of utility arches like passive arches, intrusion arches, and retraction/protrusion arches and how they are activated to apply specific orthodontic forces.

Anchorage management is essential in orthodontics to control unwanted tooth movement during treatment. Various classifications and sources of anchorage are discussed. Anchorage planning and different savers like reinforcement, subdivision, tipping, and skeletal anchorage can help minimize anchorage loss. Different appliance systems utilize anchorage differently, like the edgewise appliance relying on distal tipping of posterior teeth to neutralize forces. Maintaining optimal force levels and proper anchorage are key to achieving desired tooth movements.
This document discusses various methods and appliances for distalizing maxillary molars, including removable and fixed options. Removable appliances discussed include extraoral traction using headgear as well as removable appliances with finger springs or sliding jigs. Fixed appliances discussed include intramaxillary devices like Wilson's 3D appliance as well as intermaxillary appliances like Herbst or Jasper Jumper. Factors like the presence of second molars, skeletal pattern, and growth prognosis must be considered when determining whether molar distalization is indicated.

The document provides an overview of the activator appliance and its modifications. Some key points:
- The activator was developed in the early 1900s as a way to induce functional growth modifications. It works by applying muscle forces to the jaws through light contact between the appliance and teeth.
- There are different types of activators (H-activator and V-activator) depending on the amount of vertical opening and anterior positioning in the construction bite.
- The appliance is indicated for Class II and III malocclusions, open bites, and other functional issues in growing individuals. Contraindications include non-growing patients and severe vertical growth patterns.
- The activator is thought to work
The document discusses headgear, including:
- A brief history of headgear from the late 1800s to present day.
- The components and assembly of headgear including head caps, neck straps, face bows, molar bands and tubes.
- The types of headgear including high pull, low pull, and combinations.
- The uses of headgear such as for growth modification in class II malocclusions, anchorage reinforcement, molar distalization, and space maintenance.
- Guidelines for headgear force prescription, wear time, and expected tooth movements.
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.
The document discusses orthodontic bracket prescriptions, including:
1) Early edgewise brackets required wire bends to control tooth movement, while contemporary brackets have built-in prescriptions for in-out, tip, and torque adjustments.
2) Lawrence Andrews introduced the pre-adjusted edgewise appliance with customized brackets programmed for specific tooth control without wire bends.
3) Later prescriptions like Roth and MBT incorporated changes like more torque in upper incisors to compensate for bracket limitations, while individual adaptations are often needed for specific cases.

The twin block appliance was developed in 1977 to treat a young patient with a Class II malocclusion caused by luxation of an upper central incisor. It consists of simple bite blocks with inclined planes at 70 degrees to apply forward and downward force on the mandible. The twin block uses natural muscle forces to encourage favorable skeletal and dental changes. It can be used to treat a variety of malocclusions in both growing and adult patients. Advancements in design have improved function, retention, and patient comfort.
This document provides an overview of activator appliances, including:
- Their history dating back to the late 19th century and development by Andresen and Haupl in the early 20th century.
- Their mode of action in activating muscle forces through myotactic reflexes and condylar adaptation.
- Effects on both skeletal and dentoalveolar structures through guiding eruption and alveolar bone growth.
- Indications for use in Class II malocclusions and open bites.
- Construction process including construction bites and trimming guides to achieve desired tooth movements.
- Advantages of starting treatment later in the mixed dentition and potential for long-term retention.

This document provides an overview of the Twin Block appliance. It discusses the history, components, phases of treatment, modifications, advantages/disadvantages, and comparisons to other appliances. The Twin Block was developed in 1977 to correct Class II malocclusions by posturing the mandible forward full-time. It consists of upper and lower bite blocks connected by inclined planes. Treatment involves an active phase to correct the bite, followed by a support phase as teeth settle into occlusion. Modifications include adding screws, magnets, or facemasks for different applications. The Twin Block is effective at correcting malocclusions with minimal patient compliance issues.
This document discusses different types of anchorage used in orthodontics. Anchorage can be defined as the resistance to unwanted tooth movement during orthodontic treatment. The document describes minimal anchorage techniques like stops, tip backs, and tie backs that allow some anchorage loss. It also discusses moderate and maximum anchorage techniques and the importance of anchorage selection based on factors like dental crowding, facial profile, and tooth morphology. Absolute anchorage using implants is also mentioned.

Activator /certified fixed orthodontic courses /certified fixed orthodontic...Indian dental academy
The document discusses the history and use of the activator appliance for treating Class II malocclusions. It describes how the activator was developed from earlier functional appliances in the late 1800s/early 1900s. The activator works by positioning the mandible forward through muscle activity and tissue stretching, though there are differing theories on its exact mechanism. Construction of the activator involves taking a bite registration that guides the mandible into the desired forward and/or open position to stimulate targeted muscle forces.
Mode of action of functional appliances / dental implant coursesIndian dental academy
Functional appliances work through three main mechanisms:
1. Correction of malocclusion by controlled movement of teeth into a desirable bite.
2. Modification of craniofacial skeletal growth, especially through tooth-borne appliances.
3. Stimulation of neuromuscular adaptation by creating a new pattern of jaw closure.
This leads to changes in condylar growth and positioning, muscle activity, and eventual skeletal remodeling into the new functional matrix established by the appliance.

THE INVISALIGN aligner in orthodontics .pptxMaen Dawodi
- The concept of producing tooth movement using a removable tooth positioning device at 1945, until Align Technology computerized the process (CAD-CAM) in the late 1990s
- The clinician must treat the patient virtually using the computer images long before touching even a single tooth.
- The lnvisalign System consists of mindset, software, impressions, working with the computer, understanding physical properties and behavior characteristics of the plastic and ensuing force systems acting on teeth, as well as patient management.
- Impressions must be taken with poly–vinyl siloxane (PVS) due to its superior accuracy and stability. The patient’s impressions, PVS bite registration, photographs (intraoral and extraoral) and radiographs are submitted to Align Technology in addition to the completed treatment form. (CT)
Each aligner is prescribed to be worn for 2 weeks and
is only removed for eating, drinking, brushing and flossing.
CT images of PVS impressions are transferred to a special software called "Treat" software.
imperfections of the impression are smoothed out and then submitted to the ClinCheck technique . (Santa Clara, California)
1- Bolton's discrepancy
2- Simulate physiological tooth attrition
3- Camouflage a skeletal deformity without surgery
4- Necessity to alter the tooth morphology
Initial concerns of root proximity, caries risk, good depth
of enamel .
In posterior region, use separators prior to IPR.
periapical radiographs are needed, but without such
benefit, one may safely remove 0.3 mm from
the anterior teeth and 0.6 mm from the posterior.

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.

2. HISTORY
Kingsley in 1880 introduced the term- jumping the bite for
patients with mandible retrusion. He inserted a vulcanite
palatal plate consisting of an anterior incline that guided the
mandible in a forward position when the pt closed on it. This
corrected the sagittal relationship without tipping the lower
incisors forward.
Hotz Vorbissplate was a modification of Kingsley plate. He
used it in case of deep bite retrognathism, when the overbite
was likely to cause a functional retrusion and the lower
incisors were lingually inclined by the hyperactivity of the
mentalis muscle and lower lip.
www.indiandentalacademy.com
3. The activator was originally used by Andresen with
vertical extensions to contact the lingual surfaces of
mandibular teeth. He developed a mobile loose-fitting
appliance that transferred functioning muscle stimuli
to the jaws, teeth and supporting tissues.
The progenitor of the appliance was a modified
Kingsley plate that Andersen used as a retainer over
summer vacation for his daughter after he removed
fixed appliance used to correct distocclusion. Seeing
the improvement with this retainer, he called it
biomechanical working retainer.
www.indiandentalacademy.com
4. Pierre Robin – developed monobloc prior to Andersen
appliance.
Andersen became associated with Haupl at the university of
Oslo. Both termed the appliance as Activator because of its
ability to stimulate muscle forces.
Haulp concept of individual optimum. The limitation of the
appliance is that it cannot create a large mandible from a small
one, but can help pt achieve optimal size consistent with
morphogenetic pattern.
The original appliance combined an upper and a lower plate at
the occlusal plane. Only one wire element was used- a labial
arch for the upper ant. teeth. To achieve expansion, the
appliance was split in the centre and a flexible coffin spring
was incorporated.
www.indiandentalacademy.com
5. DRAWBACK OF ACTIVATOR
THERAPY
1. Dual bite can be a late consequence of activator
treatment with a false indication.
Indicated in retroposition of the condyle in the fossa
as a result of dominant retrusive activity of the
posterior temporalis, deep masseter and the hyoid
musculature associated with deep bite.
2. Jumping the bite should be performed without
proclination of the lower incisors. Failure of activator
therapy occurred as a result of overjet reduction due
to proclination of teeth instead of bodily anterior
positioning of the mandible.
www.indiandentalacademy.com
6. EVOLUTION OF APPLIANCE
Eschler – developed modification of the labial
bow that improved intermaxillary
effectiveness. One part was active, moving the
teeth, the other was passive, holding the soft
tissue of the lower lip away and thus
enhancing the tooth movement desired.
www.indiandentalacademy.com
8. The initial appliance was worn at night and hence its bulk
was not critical. Subsequent modifications made to reduce
the bulk allowed an increase in wearing time. They were two
types of modifications-
1. Some appliance consist of one rigid acrylic mass for the
maxillary and mandibular arches but with reduced
volume/bulk.
a. Appliance were reduced in the anterior palatal region- open
activator. Their goal is to restore exteroceptive contact
between the tongue and palate, which is prevented in the
classical activator. Pt prefer it as they are reduced in the
linguoincisal area and do not obstruct the oral cavity.
www.indiandentalacademy.com
10. disadvantages- construction bite cannot be opened too far
vertically because it impairs the tongue function. The tongue
may thrust into the anterior interincisal gap, creating a postural
and functional abnormality.
elastic open activator ( Klammt)- lack of support in the cutaway
area of the appliance, especially if guidance of erupting teeth
or expansion is necessary.
b. Appliance with reduced alveolar region and with cross palatal
wires instead of full acrylic plate. They are supported/anchored
dentally. Hence due to their tooth borne anchorage their use is
limited and management can be difficult. The labial bow
eliminates abnormal muscle pressure by extending into the
buccal vestibule area.
www.indiandentalacademy.com
11. 2. Appliance consist of two parts joined with wire bows. The
muscle impulse are reinforced by the wire elements
incorporated in the design. The flexibility of the appliance
permits mandibular movements in all directions.
a. Schwartz double plate
b. Stockfish- elastic activator
Difference in the mode of action of rigid one piece activator
(long lasting tonic phase reflex contraction) and flexible two
piece joined by intermaxillary wiring (transient phase reflex
contraction)
www.indiandentalacademy.com
14. FORCE ANALYSIS
When activator activates the muscles, various types of forces are
created-
a. Static force- permanent and vary in magnitude and direction. They do
not appear simultaneously with the movement of mandible. Eg- forces of
gravity, posture and elasticity of soft tissue and muscle.
a. Dynamic force- interrupted, appear simultaneously with the movements
of the head and body and have a higher magnitude than static force. Eg-
swallowing
a. Rhythmic force- associated with respiration and circulation. They are
synchronous with breathing and their amplitude varies with the pulse.
Imp. In stimulating cellular activity. Mandible transmits rhythmic
vibrations to the maxilla. The applied forces are intermittent and
interrupted. Force application to the teeth are intermittent. Removal of
activator from mouth interrupts these forces.
www.indiandentalacademy.com
15. Two principles are applied in modern activator
therapy-
force application- muscle
force elimination- the dentition is shielded
away from normal and abnormal functional
and tissue pressure by pads, shields and wire
configuration.
www.indiandentalacademy.com
16. Types of forces employed in activator therapy-
a. Natural force- growth potential, eruption and migration of teeth. These can be
guided, promoted or inhibited by the activator.
a. Artificially functioning forces- muscle contraction and stretching of soft tissues
initiate forces when the mandible is relocated from its postural rest position by
the appliance. The activator stimulates and transforms the contractions. Whereas
the forces may be muscular in origin, their activation is artificial.
sagittal plane- effect on the condyle
vertical plane- teeth and the alveolar process are loaded with or relieved of
normal forces. If the construction bite is high it will inhibit the growth of maxilla
and influence the inclination of the maxillary base.
transverse plane- midline correction
c. Various active elements (springs, screws) can be built into the activator to
produce an active biomechanical type of force application.
www.indiandentalacademy.com
17. CONSTRUCTION BITE
Horizontal H activator- low construction bite
with marked forward mandibular positioning
a. Class II functional retrusion
b. Class II Div 1 malocclusion with sufficient
overjet
c. Class II Div 1 malocclusion with posterior
positioning of the mandible caused by
growth deficiency but with the likelihood of
a future horizontal growth pattern
www.indiandentalacademy.com
19. Vertical V activator- high construction bite
with slightly anterior mandibular positioning
a. Class II Div 1 malocclusion with vertical
growth direction
www.indiandentalacademy.com
27. TRIMMING OF ACTIVATOR
PRINCIPLES-
The movement and eruption of selected teeth
can be achieved by grinding away areas of
acrylic that contact the tooth surface.
Carefully planned grinding and trimming of the
activator in the tooth contact area improves its
effectiveness in the dentoalveolar region by
stimulating or restricting selective eruption and
movement of anterior and posterior teeth.
www.indiandentalacademy.com
28. The principles of force application in the trimming process
are determined by the typa, direction and magnitude of force
created by the loosely fitting appliance
a. Intermittent force- isotonic and isometric muscle contractions
enabling the appliance to work by utilizing kinetic energy.
b. The direction of the desired force is determined by selective
grinding of the acrylic surface that contact the u & l teeth.
After proper grinding the desired force acts on predetermined
areas of the teeth and applies pressure in the direction of
needed tooth movement.
.
www.indiandentalacademy.com
29. c. The magnitude of force can be estimated by determining the
amount of acrylic contact with the tooth surface. If the force is
delivered to smaller portion of tooth surface, it is greater than
if broader contact occurs between the acrylic and broader tooth
surface. Acrylic surface that transmit the desired force and
contact the teeth are called guide planes.
d. Approximate trimming can be done on the plaster cast but the
final trimming is done in the mouth. Any undercut acrylic
surface that might interfere with planned tooth guidance must
be removed. Need for trimming can be assessed by-
explorer
observing the shadows created on the acrylic by the undercut

31. TRIMMING OF ACTIVATOR
FOR VERTICAL CONTROL
Intrusion
Prevention of teeth from eruption
Teeth are free to erupt and are stimulated to do
so by acrylic planes
www.indiandentalacademy.com
32. INTRUSION OF TEETH
Incisors-
Performed by loading the incisor edges
Indicated in deep overbite case
www.indiandentalacademy.com
33. Molars-
Performed by loading the cusps of teeth
Acrylic detail is ground away from the fissures
and fossas to eliminate any possible inclined
plane stimulation to molar movement
Indicated in open bite cases
www.indiandentalacademy.com
34. EXTRUSION OF TEETH
Incisor-
Loading the lingual surfaces above the area of
greatest concavity in the maxilla and below
this area in the mandible
Enhanced by placing the labial bow above the
area of greatest convexity
Indicated for open bite cases
www.indiandentalacademy.com
36. Molars-
Loading the lingual surfaces of teeth above the
area of greatest convexity in the maxilla or
below this area in the mandible
Indicated in deep bite cases
www.indiandentalacademy.com
37. SELECTIVE TRIMMING OF THE
ACTIVATOR
By this only the u & l molars are extruded
Path of eruption of molars should be
considered
In case of Class II malocclusion- eruption of
maxillary molar is inhibited while that of the
mandibular molars is stimulated
In case of Class III malocclusion- eruption of
mandibular molar is inhibited while that of the
maxillary molars is stimulated
www.indiandentalacademy.com
38. TRIMMING OF ACTIVATOR
FOR SAGITTAL CONTROL
By this protrusion or retrusion of incisors and
change in molar sagittal relationship mesially
or distally can be achieved.
