The document provides a history of the development of the face bow dental instrument. It discusses how the face bow was introduced in the late 1800s and evolved over time. Major developments included Balkwill introducing a method to measure jaw angles in 1866, Luce using photographs to study jaw movements in 1889, and Snow developing the first true face bow device in 1889. The document outlines the parts of a face bow and different types including arbitrary and kinematic face bows. It explains how face bows are used to transfer jaw relationships to articulators to allow for accurate mounting of dental casts.

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.
In prosthodontics, replacing the missing, without affecting the other components of the masticatory system has two main reference the maximum intercupation and the centric relation.
In this lecture discussion of centric relation as reference is exposed.
The human mandible can be related to the maxilla in several positions in the horizontal plane. Among these centric relation is a significant position, because of its usefulness in relating the dentulous and edentulous mandible to maxilla, where the teeth , muscles and temporomandibular joint function in harmony. It is a position of occluso-articular harmony.

CONCLUSION
DEFINITION OF FACEBOW
A caliper like instrument used to record the spatial relationship of the maxillary arch to some anatomic reference point or points and then transfer this relationship to an articulator; it orients the dental cast in the same relationship to the opening axis of the articulator; customarily the anatomic references are the mandibular transverse horizontal axis and one other selected anterior reference point. (GPT 9)
HISTORY OF FACEBOW
HISTORY OF FACEBOW
A.D. Gritman gave the statement : the implement devised by Prof. Snow as a bow of metal that reaches around the face. The face-bow is also a convenient instrument for supporting the casts while they are being attached to the articulator” : hence the term “FACEBOW”
According to Prothero , Thomas L.Gilmer was the first to suggest the principle of a face bow in a paper presented at a meeting of the Illinois State Dental Society in 1882.
Richmond S. Hayes (1880): introduced the first example of functional facebow like device intended for locating the position of casts correctly in the articulator.
George B. Snow (1899): is credited for the development of modern traditional facebow.
THE EVOLUTION OF THE FACEBOW
BONWILL – 1860
The distance between the centre of the CONDYLE and the MEDIAN INCISAL POINT OF THE LOWER TEETH - 10cm.
BALKWILL – 1866
The angle formed by the occlusal plane of the teeth and the line passing through the condyle to the incisal line of the lower teeth - 22 – 30 degrees
He could also determine approximately the distance from each condyles and ‘the front of the gums.
THE ARTICULATING CALIPER
Richmond S. Hayes - 1889
Did not enable a fixed transfer or three dimensional orientation of the cast to the articulator.
With discs C, placed on the cheeks over the condyles and the point of rod D pressed into the wax occlusion rim, this one relationship was used to determine the position of cast in the articulator.
FACIAL CLINOMETER
WILLAM E. WALKER – 1896.
Was used only for measurement of the condylar inclination.
First instrument deviced to determine the individual relationship and movements of the mandible for the purpose of constructing mechanisms for imitating these movements.
GYSI CONDYLE PATH REGISTER
GYSI – Towards the end of the 19Th Century
With the condylar graphic tracing device and incisor point marker Gysi was capable of tracing the gothic arch as well as the condyle paths on both vertical and horizontal plane.
THE PLANE OF ORIENTATION
A horizontal plane established on the face of the patient by one anterior reference point and two posterior reference points from which measurements of the posterior anatomic determinants of occlusion and mandibular motions are made. (GPT-9)

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

Lung Cancer: Artificial Intelligence, Synergetics, Complex System Analysis, S...Oleg Kshivets
RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

2. FACE BOW
“A Caliper like device which is used to record
the relationship of the jaws to the
tempromandibular joint and to orient the casts
on the articulator to the relationship of the
opening axis of the tempromandibular joint” -
GPT
2
3. HISTORY AND DEVELOPMENT OF FACE
BOW
In 1866, Francis H Balkwill introduced an
instrument for measuring the angle formed
between the plane of two lines drawn from
the articulating surfaces of the condyle on to
the incisal point and the occlusal plane.
He estimated this angle now known as the
BALKWILL’S ANGLE.
-It has an average value of 26°
3
5. 5
In 1889, CHARLES E.LUCE used what he called
the photographic method to record the relative
movements of 3 points on the mandible, the condyle,
the angle and the symphisis.
Luces results corroborated Balkwill’s findings and
there was considerable individual variations in the
relative movement of the condyle, the angle and the
symphisis.
7. 7
In 1896, WILLIAM E.WALKER introduced
the facial clinometer
-designed to determine the angle of the
condylar paths on the face
Origin of extraoral method for recording
mandibular movements
It didn’t allow for active transfer of the cast in
the articulator
9. 9
In 1884, GEORGE K. BAGBY, obtained a
patent for the Jaw gauge.
This is described as the attachment to determine
the location of the impression models in the
articulators.
In 1889, RICHMOND S. HAYES introduced the
first example of a functional face bow like device.
It was used for locating the position of casts
correctly in the articulator and he named it as the
Articulating caliper.
10. 10
In 1889,GEORGE B.SNOW developed the face
bow which carries the relationship between the
maxilla and the condyles, from the patient to the
articulator.
The snow type of face bow uses estimated
marks on the skin at the condyle points as the hinge
axis position.
Snow used the ala-tragus line as the plane of
reference.
12. 12
In 1908, GYSI developed a face bow primarily to
record the paths of the condyle.
Gysi used the prosthetic plane which is similar
to the camper’s plane as the plane of reference
In 1902,JOHN B.PARFITT introduced his
anatomical articulator also called a model jaw.
PARFITT introduced two mandibular face bows
one to transfer the casts to the articulator and
another one to produce the record of the contour of
the condylar path.
15. 15
In 1924,WADSWORTH introduced a
‘T’attachment type of a face bow.
It used a third point of reference indicator to
determine the vertical position.
This reference point is based on the naso-optic
condylar triangle.
17. 17
Many modifications evolved out of the snow face
bow.
The new trend of using the infra orbital pointer
as the third point of reference was invented in the
late 1920’s.
The Hanau, Bergstrom and the Dentatus
company where among the first to adopt it.
it’s true origin is unknown.
20. PARTS OF A FACE BOW
“U” shaped frame
- all other components of the face bow are
attached to the frame with the clamps.
- it records the plane of the cranium.
Condylar rods
- these are two small metallic rods on either
side of the free end of the “U”shaped frame
- it helps to locate the hinge axis or the
opening axis of theTMJ.
20
21. 21
Bite fork
-it’s a U shaped plate which is attached to the
occlusal rims while recording the orientation
relationship.
Locking device
-part of the face bow that attaches the bite fork to
the U shaped frame.
-also supports the face bow,occlusal rims and the
casts during articulation.
22. 22
Orbital pointer
-it marks the anterior reference point
-it can be locked in positioned with a clamp
-it only present in the arbitary face bow
23. KINEMATIC FACEBOW
Used to locate the true terminal hinge axis
Difficult to perform accurately in edentulous
situations due to REALEFF
Indicated for the fabrication of FPD
23
25. ARBITRARY FACEBOW
The condylar rods are positioned
approximately 13mm anterior to the auditory
meatus on the cantho-tragal line.
This locates the rods within 5mm of the true
hinge axis of the jaw.
This is commonly used in complete denture
constuction.
25
27. TYPES
Facia type
-Posterior reference point is 13mm anterior to
external auditory meatus
-Anterior reference point is the orbitale
Ear piece type
-Posterior reference point is the EAM
-Anterior reference point is the orbitale
27
28. 28
Denar facebow
-Ant. reference is 43mm above the incisal
edge of right central or lateral incisor
-It is marked using a denar reference plane
locator
Twirl bow
-It relates the maxillary arch with the
frankfort horizontal plane
-It doesn’t require any physical attachment
to the article
30. 30
Whipmix facebow (quick mount FB)
-Nasion related assembly with a plastic nose
piece which determines the anterior reference
point
-It has a built in hinge axis locator ;
automatically locates the hinge axis
31. HINGE AXIS
Hinge axis is an imaginary line around which the
condyles can rotate without translation
In 1921,McCollum,Stuart reported the discovery
of first method locating hinge axis
Controversies as to the presence of a single
axis,the method and validity of recording the
position on the skin have arisen because
mechanical equipment is used to record
movements involving living tissues
31
32. TERMINAL HINGE AXIS
(TRANSVERSE HINGE AXIS)
It is an imaginary line which passes horizontally
through the rotational centers of the right and
left condyles when they are in the most distal
retruded position in their respective glenoid
fossa
The technique for locating the terminal hinge
axis position is the same for dentulous and
edentulous patients
32
33. The hinge axis locating bow is attached rigidly to
the mandible by means of a clutch
Clutch is cemented over the teeth or clamp to
the edentulous ridge
Mandible is manipulated to the centric relation
The patient makes guided opening and closing
movements within the range of hinge opening
Adjustments are made untill the stylii on the
hinge axis bow only spin
This indicates that the stylii are co-linear with
the mandibular hinge axis
33
34. ARBITRARY HINGE AXIS
Most indirect techniques in dentistry does not
require the accuracy of locating the true hinge
axis
WEINBERG in a study evaluated the degree of
error of axis location and its relationship to the
occlusion of teeth
He concluded that ‘the transverse hinge axis
location and the subsequent face bow transfer
within a 5mm error is a practical and dependable
method for orienting the maxillary cast’
34
35. FACEBOW TRANSFER
ARBITRARY AXIS FOR HANAU FACEBOW
- Richey condylar marker is used to scribe an
arc 13mm anterior to the external auditory
meatus.
- using a ruler, a line is drawn from outer
canthus of the eye to the tragus of the ear.
- the point where the line intersects the arc
locates the arbitrary axis
35
37. 37
The bite fork is heated and inserted in to the
maxillary rim parallel to the occlusal plane.
The recording base is inserted into the mouth, the
extension rod is pass through the locking device.
The condylar rods are oriented over the arbitrary
centres of rotation.
They are moved from side to side untill the
readings on the condyle rod scales are same on
both sides
40. 40
The cross bars should be parallel to a line between
the pupils of the eye
The lock nuts at the condyle rods are tightened to
suspend the facebow and the bite fork is securely
attached
Condylar lock nuts are released and the facebow
and occlusal rim are transferred to the articulator
The instrument is locked in centric with the
incisal pin flush with the upper member
41. 41
The facebow is adjusted by the elevating screw
to align the occlusal plane with the groove mark
on the half-way point of the incisal pin
A hanau mounting support or prop may be
necessary to support the weight of maxillary cast
and plaster during mounting
42. INDICATIONS
Cusp form of teeth are used
Balanced occlusion in the eccentric position
are desired
Interocclusal check records are used for
verification of jaw position
Occlusal vertical dimension is subject to
change and alteration of tooth occlusal
surfaces are necessary to accommodate the
changes
42
43. CONCLUSION
Blind orientation of the maxillary casts on a
articulator will result in errors
The elimination of errors that can be
produced by failure to use a facebow where
indicated, justifies the time required and the
procedures involved in the facebow transfer
