The document discusses the process of recording jaw relationships using a facebow, including establishing the maxillary facebow record and transferring it to an articulator. It explains that the facebow establishes the spatial relationship between the maxillary arch and condylar axis, which is important to transfer to prevent occlusal errors when mounting dental casts. The facebow record involves marking the condylar axis location, stabilizing a bite fork intraorally, fitting the facebow clamp and adjusting the condylar rods and infraorbital pointer based on anatomical landmarks.

When treating a patient with a removable partial denture, the natural and artificial teeth, both functionally and esthetically, must co-exist in a harmonious relationship.
Occlusal harmony between a removable partial denture and the remaining natural teeth is a major factor in preservation of the surrounding structures.
In removable partial dentures, because of the attachment of the denture to abutment teeth, occlusal stresses can be transmitted directly to the abutment teeth and other supporting structures, which results in sustained stresses that may be more damaging than those transient stresses found in complete dentures.

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.
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.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

9. TYPES OF FACE-BOWS
1. Mandibular or kinematic face-bow (hinge axis
face-bow). This locates the exact axis of
rotation of the condyles.
2- Maxillary face-bow
a. Kinematic facebow used to locate and
transfer true hinge axis.
b. Arbitrary face-bow This relates the maxilla to
the exact or arbitrary position of the condylar
axis and transfers this relationship to the
articulator.
10. Facebow record and Transfer
• Establishes the
relationship between the
maxillary arch and the
horizontal plane.
• Transfers this
this relationship
to the articulator.
Maxillary Face bow
11. Purpose
• To accurately mount the
maxillary cast to articulator
The facebow record transferred to
the articulator Important to prevent
occlusal errors
12. What if patient doesn’t match
articulator?
Articulator
Patient
14. Articulators
We obtain a measurement of this distance
with a facebow
aha
mha
occlusal errors
The lnterocclusal wedge space will not be equal
15. • Therefore the distance from the condyle
to the teeth is crucial, we obtain a
measurement of this distance with a
facebow
16. Face-bow Function
• Duplicates opening and closing arc of
natural teeth by relating maxillary arch to
the hinge axis.
• Slight change of vertical dimension doesn’t
affect the relation
17. The first part of the
posterior border
opening is a rotation
around the hinge axis.
If the terminal hinge axis is recorded on
the articulator using a hinge face-bow, then
minor changes in the vertical dimension
will not alter the horizontal jaw relation.
18. N.B.
The face bow records not only the radius from the
condyles to the incisal contacts of the upper central
incisors but also the angular relationship of occlusal
plane to the axio-orbital plane, face bow must be
positioned on the articulator in the same axio-orbital
relation as on the patient.
21. 1 . Maxillary face-bow or ear-bow.
2 . Bite-fork.
3 . Bunsen burner
4. .Millimeter ruler.
5 . Indelible pencil (Transfer Sticks)
6 . Semi-adjustable articulator.
7 . Plaster bowl and spatula.
8 . A second maxillary record bases with
occlusion rim.
EQUIPMENT NECESSARY
22. Maxillary face-bow record
11-13 mm
11-13 mm
The condylar axis lies nearly 11
mm anterior to the tragus of
the ear on an imaginary line
between the outer canthus of
the eye and the upper surface
of the tragus of the ear or lies
13 mm in front of the anterior
margin of the external auditory
meatus.
1- Mark the relative position
of the condylar axis.
23. Cont. Maxillary Face Bow Record
The condylar axis
is determined
either arbitrarily or
by using
mandibular face
bow record.
24. Maxillary Face Bow Record
2- Bite fork is heated and inserted into the rim
midway its height and parallel to its plane.
Both are then placed intraorally together with the lower
occlusion block.
Edentulous Bite Fork: Allows
patient to close against the
opposing rim to stabilize the
record bases
25. 3- Insert occlusion block
in patient’s mouth and
keep it in place.
The lower occlusion
block may be used for
this purpose to support
the upper block.
Maxillary face-bow record
26. 4- Slip the clamp of face-bow on the
stem of bite fork. Let the clamp be
loose.
Maxillary face-bow record
27. A- Both condylar rods lie on cheek
marks.
B- Condylar rods show equal
calibration with slight tension.
Maxillary face-bow record
Adjustment of the condylar
rods of face-bow to the
width of the face in such a
way that:
28. Maxillary face-bow record
5- Adjust the infra-orbital pointer
6- Generally the intercondylar axis will
parallel the interpupillary plane. Check the
alignment of the face-bow with that plane.
29. 7- The universal joint attachment is then
tightened with the locknut and the entire
assembly is inspected to make certain that:
Maxillary face-bow record
30. Remember
When the patient’s face is centralized in the bow, all
clamps are tightened.
Notice position of the
Condylar Rods
Infraorbital Pointer
& Bite Fork.
Once the Universal joint
tightened, never opened.
31. A- The maxillary record base is properly
seated.
B- The fork parallels the occlusal plane.
C- The frame of the face-bow parallels the
interpupillary plane.
D- The condylar rods are just lightly contacting
the face over the arbitrarily located axis.
E- The condylar rods show equal readings.
F- All lock screws are firmly set.
32. Maxillary Face Bow Transfer
8- The slide bar clamp is unscrewed and
The entire assemblage is now removed
and transferred to the articulator.
33. Cont. Maxillary Face Bow Transfer
9- Assembly is now centralized on the articulator.
Again notice position of
- condylar rods
- infraorbital pointer
- L shaped bitefork bypassing incisal pin
