The document discusses temporomandibular joint disorders (TMD) and their relationship to orthodontic treatment. Some key points:
- TMD signs and symptoms are common in the general population and usually increase with age, unrelated to orthodontic treatment.
- Orthodontic treatment does not increase or decrease the risk of developing TMD. No specific orthodontic mechanics are linked to higher risk.
- Achieving an ideal occlusion does not prevent TMD, and no method of prevention has been proven effective. TMD is usually alleviated by simple, conservative treatments in most cases.

The simplicity of bonding can be misleading. The technique undoubtedly can be misused, not only by an inexperienced clinician but also by more experienced orthodontists who do not perform procedures with care.
Success in bonding requires understanding of and adherence to accepted orthodontic and preventive dentistry principles.
The advantages and disadvantages of bonding versus banding of different teeth must be weighed according to each practitioner’s preferences, skill, and experience.
Bonding should be considered as part of a modern preventive package that also includes a strict oral hygiene program, fluoride supplementation, and the use of simple yet effective appliances. In other words, complicated mechanics with abundant use of coil springs and multilooped arches lends itself less well to bonding and easily can compromise the integrity of tooth enamel and gingival tissues around brackets on small bonding bases.
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

Conclusion
Skeletal maturity is assessed through examination of ossification centers in bones like the hand and wrist. The Greulich and Pyle atlas and Bjork method involve comparing radiographs to standardized images to determine skeletal age. Singer's method stages skeletal maturity based on characteristics like the width of epiphyses compared to diaphyses and appearance of sesamoid bones. Assessing skeletal maturity is important for orthodontic treatment planning by indicating remaining growth potential.

This document provides an overview of orthodontic archwire materials. It discusses the history of archwire materials including precious metals, stainless steel, cobalt chromium alloys, and nickel titanium alloys. The basic elastic properties of archwires like stress, strain, modulus of elasticity, and stiffness are explained. Clinical implications of archwire selection including size, shape and fabrication are covered. Recent advancements in braided, twisted, triangular, and non-metallic wires are also summarized.
A magnet (from Greek μαγνήτης λίθος, "Magnesian stone") is a material or object that produces a magnetic field .This magnetic field is invisible and causes the most notable property of a magnet a force that pulls on nearby magnetic materials, or attracts or repels other magnets.
Magnets attract specific metals, and they have north and south poles. Opposite poles attract each other while like poles repel.
determinate vs indeterminate force systemKumar Adarsh
This document discusses force systems in orthodontics. It describes determinate and indeterminate force systems, with determinate systems providing better control of forces and moments. One-couple systems are created using a cantilever spring or auxiliary arch wire tied to a tooth at one end. Two-couple systems are created when an arch wire is tied into brackets on both ends. Common applications of one and two-couple systems include intrusion/extrusion arches and lingual arches. Segmented arch mechanics allow precise control but require more wire bending compared to continuous arch wires.
The document discusses theories of mandibular growth and the construction bite technique used in orthodontic appliances. It describes several theories of condylar growth including the genetic control theory, functional matrix hypothesis, and lateral pterygoid hyperactivity hypothesis. It also discusses the growth relativity hypothesis. The construction bite is critical for functional appliances to work properly and involves analyzing study models, function, and cephalometrics to determine the proper vertical and horizontal positioning of the mandible. The magnitude of correction depends on factors like the type of malocclusion and developmental state.

The document discusses Bjork's concept of jaw rotation during growth. It summarizes Bjork's landmark longitudinal study from 1951-1969 that used metal implants to track sites of growth and resorption in the mandible. Bjork observed that the mandible undergoes a downward and backward rotation during growth, with greater growth occurring posteriorly than anteriorly. He classified mandibular rotation patterns into forward and backward types based on the center of rotation. The study provided insights into mandibular growth mechanisms and implications for orthodontic treatment planning.
Growth & development of maxilla and mandibleRajesh Bariker
The document discusses the pre-natal and post-natal growth and development of the maxilla and mandible. It describes how the maxilla forms from embryonic development and ossification centers. It grows through displacement, remodeling at sutures, and increases in height, width and length. The mandible develops from Meckel's cartilage and also grows through remodeling at sites of growth. The palate develops from primary and secondary palatal shelves fusing in the midline. Post-natally, the maxilla grows through apposition at sutures and displacement downward and forward from cranial base growth. The mandible grows through remodeling at sites like the ramus and condyle.
The document discusses prenatal and postnatal growth of the mandible. It describes how the mandible develops from mesenchymal condensations in the pharyngeal arches during prenatal development. It forms through both intramembranous and endochondral ossification. The condyle, coronoid process, and mental region develop through endochondral ossification of cartilage models. Postnatally, the mandible grows downward and forward through appositional bone growth at the condyle, ramus, and alveolar processes to accommodate the permanent dentition. The chin develops through periosteal bone apposition on the lingual surface in males during late growth.
The document discusses temporomandibular joint disorders (TMD) and their relationship to orthodontic treatment. Some key points:
- TMD signs and symptoms are common in the general population and usually increase with age, unrelated to orthodontic treatment.
- Orthodontic treatment does not increase or decrease the risk of developing TMD. No specific orthodontic mechanics are linked to higher risk.
- Achieving an ideal occlusion does not prevent TMD, and no method of prevention has been proven effective. TMD is usually alleviated by simple, conservative treatments in most cases.

This document provides an overview of bone physiology. It begins with definitions of bone and its functions, including supporting the body, protecting organs, and allowing movement. It then covers the classification, anatomy, histology, composition, growth and remodeling of bone. Key points include that bone is made up of inorganic minerals and organic collagen matrix, and is in a constant state of breakdown and formation through the actions of osteoclasts and osteoblasts, maintaining homeostasis. The document provides details on intramembranous and endochondral ossification, as well as the structure of alveolar bone and its importance for dentistry.

This document provides an overview of musculoskeletal fractures, including:
1. It discusses the stages of fracture healing, classifications of fractures, and factors that can affect healing like smoking or diabetes.
2. The normal timescales for fracture healing are outlined in 5 stages from inflammation to remodeling, taking 6-8 weeks for bone to become secure.
3. Principles of fracture management include reduction, immobilization, and rehabilitation. Methods of stabilization range from splints to casts to internal or external fixation devices.
4. Potential complications of fractures are also reviewed from immediate issues like blood vessel injury to late issues like malunion, nonunion, or avascular necrosis.
Crocodile Tears Syndrome (Bogorad's Syndrome) is a condition that usually occurs during recovery of Bell's palsy. Synkinesis of the facial nerve is responsible for the symptoms (crying instead of salivating, salivating while crying, etc.).
The skeletal system has several important functions:
1) It provides structure and support for the body, protects delicate organs, and acts as levers for muscle movement.
2) Bones also function in mineral storage and blood cell formation.
3) The skeletal system is divided into the axial skeleton (which includes bones such as the skull, vertebral column, ribs, and sternum) and appendicular skeleton (which includes the bones of the upper and lower limbs).

This document summarizes the classification of bones based on shape, development, region, and structure. It discusses the different types of bones such as long bones, short bones, flat bones, and irregular bones. It also describes the types of cartilage, classification of joints, and provides additional facts about bones.
The document discusses the process of bone fracture healing, including the stages of hematoma formation, cellular formation, callus formation, ossification, remodeling, and the factors that influence healing such as growth factors, cytokines, hormones, blood supply, and stability of fixation. Fracture healing occurs either through indirect healing via callus formation or direct healing with bony bridging depending on the stability of the fracture fixation.
The tongue develops from tissues originating in the pharyngeal arches and swellings in the floor of the mouth. It begins developing at 4 weeks as a tuberculum impar surrounded by two lateral lingual swellings that merge to form the anterior two-thirds of the tongue. The root develops from the hypobranchial eminence originating in the third arch. Muscles of the tongue originate from occipital somites and are innervated by the hypoglossal nerve. The anterior two-thirds receive innervation from the trigeminal nerve and the posterior third from the glossopharyngeal nerve. The tongue separates from the floor of the mouth and develops four types of lingual papillae

The document discusses growth and development of the maxilla from prenatal to postnatal periods. It describes how the maxilla develops from maxillary processes in the embryo. During prenatal growth, the maxilla is displaced downward and forward as the cranial base grows. Postnatally, the maxilla grows through bone deposition, remodeling at sutures, and expansion of the maxillary sinus. The primary palate develops early from the median palatine process, while the secondary palate forms from the palatine shelves fusing in the midline.
The mandible develops from mesenchyme of the first arch. It forms lateral to Meckel's cartilage through intramembranous ossification beginning in the 7th week. Ossification spreads to form the body, rami, and mandibular canal enclosing the inferior alveolar nerve. Secondary growth cartilages including the condylar, coronoid, and symphyseal cartilages further develop the mandible through birth. Meckel's cartilage degenerates except for portions that form ear structures.

Growth and development of the mandible /certified fixed orthodontic courses...Indian dental academy
The document discusses the growth and development of the mandible from prenatal to postnatal stages. It describes how the mandible develops from neural crest cells and the main sites of growth, including the condylar cartilage, rami, alveolar processes, and symphysis menti. The condylar cartilage contributes to overall mandibular length through endochondral bone formation, though its role as the primary growth center is debated. Other factors like muscles and biomechanical forces also influence mandibular positioning and shape. Growth patterns vary during development and puberty, with growth spurts typically occurring earlier in girls. Certain anomalies can also affect mandibular development.

The document discusses growth of the craniofacial complex, including the maxilla, mandible, and soft tissues. Growth occurs through bone apposition, remodeling, and endochondral ossification at sutures and synchondrosis. The maxilla grows downward and forward through remodeling and addition of bone in sutures. The mandible grows through remodeling in the ramus, resulting in a downward and forward displacement. Deviations from normal growth can occur due to trauma, disease, or genetic syndromes.

There are two types of ossification :
INTRAMEMBRANOUS
ENDOCHONDRAL

29. Parts Of Mandible Derived From
1. INTRAMEMBRANOUS OSSIFICATION
i) Whole body of mandible except the anterior part
ii) Ramus of mandible as far as mandibular foramen
2 . ENDOCHONDRAL OSSIFICATION
i)
Anterior portion of the mandible (symphysis)
ii) Part of ramus above the mandibular foramen
iii) Coronoid process
iv) Condylar process
www.indiandentalacademy.com
30. Mechanisms Of Bone Growth
Growth Of The Mandible Primarily Involve
1. Bone remodelling
Process Of Bone Deposition And Resorption
2. Cortical drift
Combination of bone deposition and resorption resulting in growth movement
towards deposition surface
3. Displacement
Movement of whole bone as a unit
I) Primary displacement
II) Secondary displacement

35. Other Theories
ENLOW’S “V”
PRINCIPLE
The growth and
enlargement of bones
occur towards wide end
of ‘v’ due to differential
deposition and
resorption
www.indiandentalacademy.com
36. Enlow’s Counterpart Principle
‘The growth
of any given facial or cranial part relates
specifically to other structural and geometric “counter” parts
in the face and cranium’.

43. Is the Condylar cartilage the principle
force that produces the displacement of
the mandible ?
For many years considered primary growth center
FMH - Condyle absent yet mandible positioned normally
Considered secondary cartilage -no intrinsic growth
potential
www.indiandentalacademy.com
44. Petrovic et al - Role of hormones
Experiments involving transplantation of the condyle
Johnston et al - Detached condyle from the body of
mandible in guinea pigs
Injection of papain - Inhibition of chondrogenesis
Koski et al - Periosteal tension in condylar neck-lateral
pterygoid- controls condylar growth
www.indiandentalacademy.com
45.
Condylar cartilage and functioning muscles translate the
mandible and in the absence of one the other does best to
compensate
Integrity of periosteum is important
When environment is changed compensatory contributions
are enhanced
www.indiandentalacademy.com
46. Current Concept
Condylar cartilage does have a measure of intrinsic genetic
programming
But extra condylar factors are needed to sustain this activity
Physiologic
inductors
Intrinsic and extrinsic
biomechanical forces
ENLOW :
Increase pressure – growth inhibition
Decrease pressure – stimulates growth

Lingual - Resorption
www.indiandentalacademy.com
54. Body of mandible
The increase in width of the mandible occurs primarily due
to resorption on the inside and deposition on the outside
Increase in length occurs due to drift of the ramus
posteriorly
Increase in height occurs due to eruption of the teeth
www.indiandentalacademy.com
58. Alveolar Process
Adds to the height and
thickness of the
mandibular body
Teeth absent fails to
develop
Teeth extracted resorbs
www.indiandentalacademy.com
59. Alveolar Process
Maintain occlusal relationship during differential mandibular
& midfacial growth– buffer zones
Maintains vertical height
Adaptive remodeling makes orthodontic tooth movement

cartilage and ventral end of Meckel’s
cartilage
