This document discusses the management of facial asymmetry. It begins by defining facial asymmetry and symmetry, and classifying types of facial asymmetries. It then discusses evaluating and diagnosing facial asymmetry through history, clinical examination, radiographs, and photographs. Treatment options are presented for different asymmetries, including orthodontic therapies like arch expansion or coordination, functional appliances, and occlusal adjustments. Surgical options for skeletal asymmetries include orthognathic surgery and distraction osteogenesis. The document emphasizes a team approach is often needed to successfully treat facial asymmetry.

Used in the right conditions, SFOA is highly successful and has a positive impact on the patients psychosocial status.A combined orthodontic and orthognathic surgery approach is accepted as the standard of care for patients who have a severe skeletal jaw discrepancy with facial asymmetry.
But some disadvantages have been recognized.
One drawback is the long presurgical treatment time that typically worsens facial appearance and exacerbates the malocclusion. In some countries, these disadvantages have caused patients to seek plastic surgeons who are willing to perform orthognathic surgeries without collaboration with orthodontists or consideration for the final occlusion.
Recently, to address patient demand and satisfaction, the surgery-first approach was introduced to overcome some disadvantages associated with the conventional surgical orthodontic approach.1991-Brachvogel et al. suggested the potential advantages of a surgery-first approach.
In that article the advantages of post-surgical orthodontics are outlined as follows:
1) Orthodontic movement does not interfere with compensatory biological responses.
2) Dental movements can be based on an already corrected skeletal pattern.
3) Some surgical relapse can be managed during treatment.
2009: Nagasaka et al., popularized SFOA54. Nagasaka et al1 were among the first to actually carry out SFOA using miniplates for post-surgical orthodontic treatment
The 2011 symposium presented the surgery‑first approach and created broader interest in the complete elimination of time‑consuming preoperative orthodontic treatment

HI THIS IS A NICE SEMINAR DESCRIBING ABOUT THE ORTHOGNATHIC SURGERY MAINLY RELATED TO ORTHODONTICS VIEWPOINT AND CEPH TRACING ITS INDICATION AND DIFFERENT TYPES OF SURGERIES. JUST HAVE A LOOK TO IT
“The study of orthodontia is indissolubly connected with that of art as related to the human face.” -Dr. Edward H. Angle.
Each person shares with the rest of the population a great many characteristics, but there are enough differences to make each human being a unique individual. Such limitless variation in the size, shape and relationship of the dental, skeletal and soft tissue facial structures are important in providing each individual with his or her own identity.
Face – Difficult object to measure accurately because of
– complex morphology
– sensitivity to eyes
– its soft nature.
One of goals of orthodontic treatment is creating a balanced & harmonious facial appearance. Craniofacial symmetry is one of the aspect of this harmony. Subject of symmetry or lack of symmetry of human face has been of considerable interest, particularly in the field of Orthodontics. Minor variation is a desirable variation of craniofacial structure which is perceived as esthetically pleasing and has no esthetic or functional significance. Asymmetry becomes important when it affects the function or esthetics of the person.

The potentiality of dental professional/ endodontists to carry out routine procedures successfully relies chiefly on the adequacy of local anaesthesia achieved. However, local anaesthetics (including lidocaine, the most commonly used local anaesthetic) have a tendency to cause pain on mucosal infiltration, which adds to patient anxiety during procedures.1 In fact, investigators have reported a more painful skin and subcutaneous infiltration with an epinephrine-containing lidocaine.2
The most probable mechanism of this pain is attributed to the reduced pH of an epinephrine-containing lidocaine compared to a plain lidocaine solution. A weakly basic amide, lidocaine being unstable at pH of 7.9, is made in acidic preparations to to enhance the solubility and prolong shelf life. Moreover, epinephrine is added to lidocaine to extend the half-life of the anesthetic, lessen toxicity, and provide hemostasis. Because epinephrine is only stable for lengthy phases in an acidic environment, the pH of commercially available premixed lidocaine with epinephrine is lower than that of plain lidocaine (pH 3.3-5.5) and the acidity can give rise to tissue irritation which may be felt by patients as a stinging or burning pain. 3,4
Based on the attributed mechanism, most common method for buffering is the alkalinisation of the lidocaine with sodium bicarbonate just before injection. Buffering with sodium bicarbonate (NaHCO3) 8.4%in a 10:1 or 9:1 ratio (10 or 9 parts lidocaine-epinephrine 1% containing 5 microgram/ml to 1 part sodium bicarbonate containing 8.4g/l) more closely matches the neutral pH (around 7.4) in human tissues and has been demonstrated to cause less CDJIpain than unbuffered lidocaine.1, 5-13
Body dysmorphic disorder (BDD), also known as body dysmorphia, body dysmorphia disorder and BDD disorder, is a mental health condition in which people suffer acute distress in response to perceived physical flaws.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2. INTRODUCTION
• Facial esthetics evaluation is the most important part of the orthodontic
treatment-planning procedure.
• The attainment of the best facial esthetic appearance for a given patient is a
primary goal of orthodontic treatment.
• The evaluation of a patient’s frontal symmetry is the most critical aspect of
diagnosis because this is the most appreciated view for any individual. Even
the most esthetic faces are associated with mild forms of facial asymmetry.
• The individuals who report for an orthodontic treatment are often
associated with facial asymmetry that may be greater than the acceptable
norms.
4. Woo (1931)-
• Bones of cranium show asymmetry- rt. side being larger
• Bones of facial complex – contralateral asymmetry.
Vig & Hewitt (AO 1975)-
• Dentoalveolar region exhibit greatest symmetry.
• Allows symmetric functions even with asymmetric jaws.
8. A. Malformations with abnormal developmental
processes in embryonic stage ( 1%)
1.Hemifacial microsomia
2.Congenital hemifacial hypertrophy
3.Cleft lip & palate
COHEN 1982
9. B. Deformations caused by non disruptive
mechanical forces during fetal period:(2%)
1.Congenital muscular torticollis
2.Postural scoliosis
3.Plagiocephaly
10. C. Disruptions caused by breakdown of normal
developmental processes with onset later in life
1.Unilateral condylar hyperplasia
2.Hemifacial atrophy
3.Infections & inflammations
4.Fracture & trauma
5.Lateral malocclusion
6.Muscular dysfunction
15. 1. Inter ocular dimensions-
interpupillary-65mm
inter canthal- 35mm
2.Midfacial bony support-
lower third of iris of the eye to be covered
with lower eyelid
16. VERTICAL
Vertical reference plane- nasion to subnasale
•upper horizontal plane – bipupillary line
• lower horizontal line - through the stomion
17. Arnett and Bergman AJO1993
•The pupils are assessed for level with the horizon.
If in level - used as horizontal reference line
•(1) upper canine level
•(2) lower canine level
•(3) chin and jaw level.
18. The pupils are not level to the horizon:
A constructed frontal horizontal reference line is
visualized as follows:
• 1. Frontal natural head posture.
• 2. Horizontal line parallel to the horizon through the
pupil area
• 3. Assess other structures relative to this line
23. RADIOGRAPHIC EXAMINATION
Importance of head position
1.The lateral cephalogram
2.The panoramic radiograph
3. Postero-anterior projection
4. Submento vertex view
5. 3-D cephalograms
24. LATERAL CEPHALOGRAM
Only little useful information
In CR ,CO and initial contact permits
visualization of mand.position
OPG:
Gross pathologies -Size &shape of condyle,
ramus &body of mandible
25. PA CEPHALOGRAM
• Important adjunct for qualitative & quantitative evaluation of
dentofacial region
• Extent of deformity( orbital/ upper facial symmetry),
• Skeletal /dental involvement.
31. SKELETAL ASYMMETRIES:
• In growing Individuals, orthopedic appliances in conjunction with
orthodontics are used to help improve or correct the developing
imbalance.
• Severe discrepancies may require a combination of surgery and
orthodontics.
• Abnormalities of the coronoid and condylar processes as well as in
the position and shape of the articular disks should be considered
when limited opening, acute mal- occlusions, or mandibular
deviations are found.
32. FUNCTIONAL ASYMMETRIES
• Mild deviations caused by functional shifts -minor occlusal
adjustments
• More severe deviations -orthodontic treatment to align the teeth
• Occlusal splints may be necessary to properly evaluate the
presence and extent of the functional shift by eliminating the
habitual posturing and de- programming the musculature.
• Because functional shift can also be the result of a skeletal
asymmetry, rapid maxillary expansion, orthognathic surgery, and
orthodontic treatment may be indicated in the management of
these cases.
33. SOFT TISSUE ASYMMETRIES
• Deformities caused by soft tissue imbalance can be treated by
either augmentation or reduction surgery.
• Augmentations include the use of bone grafts and silicone
implants to re-contour the desired areas of the face.
• With the mild dental, skeletal, and soft tissue deviations the
advisability of treatment should be carefully considered.
36. MAXILLARY EXPANSION
• 1. Slow expansion
• 2. Orthopedic rapid palatal expansion
• 3. SARPE
• 4. Segmental osteotomy
To achieve desired expansion with stability,it should be
accomplished by sutural adjustments & not by alveolar bending
dental tipping
37. SLOW EXPANSION:
• Can bring about skeletal expansion in primary dentition
• Lingual arch /quad helix- 50% sk. exp.
• Jack screw
• FR functional regulator - indirect effect
38.
39. RAPID PALATAL EXPANSION
• Very successful in children prior to sutural closure.
• 0.5mm day- 10 mm exp. in 20 days- 75- 80% of sutural
expansion
Haas type
Hyrax type
Minn expander
• 3:2 ratio of widening in canines & molars
40.
41. SARPE:
• Brown(1938)-described SARPE with midpalatal split
• Shetty(1994)-main areas of resistance to expansion
are midpalatal suture followed by pterygomaxillary
buttress
• Subtotal Lefort I osteotomy –except posterior and
superior articulations
42.
43. • Should be done after mand Decompensation
• During surgery – activated by 1- 1.5mm – 5 days of rest –0.5mm
day
• Spacing between central incisors
• Expansion completed within 4 weeks of surgery
44. Segmental Lefort I osteotomy
• Indicated in open bite cases, where SARPE is
contraindicated
•Total down fracture of maxilla followed by anterior
segmenting.
•Maximum expansion occurs in molar area
•Advantage: minimal relapse
•Disadv: exp. more than 6mm
45. Repositioning splints AJO 1991. Schmid et.al.
• Used mainly inTMJ dysfunctions
• Indicated only when it is impossible to identify functional
interferences due to neuromuscular adaptation
• Superior repositioning splints are preferred
• Regular wear for 2-3 mths enables compensatory changes in
TMJ.
46.
47. Orthopaedic Hybrid Functional Appliances
• Hybrid /blend of several components designed to address specific problems
These components produce basal and dentoalveolar changes by acting on the
following:
• 1. Eruption (biteplanes)
• 2. Linguofacial muscle balance (shields or screens)
• 3. Mandibular repositioning
48. • Functional appliances used either alone or in conjunction with
surgery for the following purposes:
• (1) to improve symmetry of the mandible and maxillary
deficiency,
• (2) to restore the dental occlusion,
• (3) to expand soft tissues
• (4) to lengthen the mandibular ramus
49. Herbst appliance:
• Works as an artificial joint between the maxilla and the mandible.
The appliance is fixed to the teeth -orthodontic bands.
• The appliance is constructed to displace the mandible anteriorly
and to the unaffected side for correction of the mandibular
retrusion and asymmetry.
• The construction bite - incisors in an edge-to-edge position ,
midline overcorrected by 3.5 mm.
50. Twin block AJO 1988 Clark
•When activated unilaterally - correct postur mand.
displacement (mid line displacement an asymmetric
buccal segment relationships).
55. Orthodontic camouflage-
When skeletal deformity is very mild and any further change is
not expected, camouflage should be considered.
1.Transverse cant correction
• 2 occlusal planes : upper &lower Connects incisal edge of C.I to
M-B cusp tip of I molars –important for normal intercuspation .
• Natural plane of occlusion: axial inclinations of premolars to be
perpendicular & that of molars mesially inclined
56. •Normal –transverse occlusal plane – esthetic&- parallel
to the transcommisural line & a line tangent to lower lip
•Asymmetry cases – transcommisural lines’ll not be
parallel to other facial planes – treatment occlusal plane
should not be parallel to facial planes
59. Occlusal therapy
•Selective grinding /Occlusal adjustment
-Reshaping the occlusal surfaces of the teeth to achieve a desired
occlusal contact pattern
-Removal of the tooth structure limited to enamel.
• Restorations of teeth –
crowns & FPDs
60. Rule of thirds
Each inner incline of posterior teeth is divided into 3 equal parts:
• If opposing centric cusp tip contacts the third closest to the
central fossa – selective grinding
• If opposing centric cusp tip touches the middle third – crowns
FPDs
• If opposing centric cusp tip contacts the cusp tip –orthodontic
arch coordination
61. DENTAL COMPENSATIONS
• Midline shifts- dental compensation to make the dental midline
shift
• Axial inclination of molars
– to compensate for the developing cross bite in the contralateral
side
• Canting of maxillary occlusal plane
62. Surgical
•Conditions with severe skeletal asymmetries are
not able to be corrected by orthodontic camouflage
and growth modification so surgical procedures
are used to correct the deformities or asymmetries.
65. CONCLUSION
•A team approach in the management of
asymmetries always produces a high degree of
success which influences the social & personal
well being of these patients.
•Joining hands together enlightens the future
of such patients.
