8. Operator_patient position,and
dental chair setting:
 Dentistry is a demanding and stressful environment.
 Operator,patient,dental chair position is one of the most
important things dentist should take in consideration before
starting any dental procedure
 Correct positioning help operator to have a good visibility
and accessibility to the oral cavity.

9.  If this relation neglected,physical problems may arise
,musculoskeletal disorder is one of theme,such as back
pain,shoulder,neck strain,disc prolapse ,varicose…etc
 If operator maintain proper working position and posture
during treatment, less strain and fatigue for the dentist
,and more efficient procedure for the patient.

10. Three important position to be
checked before starting any dental
procedure:
Dental chair position
Patient position
Operator (dentist) position

the first specialized dental chair
 It was a wooden chair with a
head rest attached
 Most dental procedure where
performed with the patient
seated upright ,and dentist
stand next to patient.

14. Dental chair
 Today's dental chair
,modern chairs ,are
Designed to provide most
support and comfort to the
patient.
 The patient head is
supported by a head rest
cushion which elevate the
chin and thus reducing
strain on neck.

15. Dental chair position
 Adjust chair to permit maximal operator access to
the working area.
 The adjustment control switches should be
conveniently located ,and to improve infection
control,chairs with foot switch for patient
positioning are recommended.
 The chair should be low,the back rest upright and
the arm rest adjusted to allow the patient to get
into the chair.

16. Dental chair position
 Patient seated ,arm rest
returned,headrest cushion positioned
.then chair adjust to place the patient
in a reclining position.

17.  Operator light is situated
above the patient 's head,
direction vary ,and should
be easily adjusted with
handles on both sides of the
light.

18.  The operating stool must have
abroad base for stability and must be
padded and offer good back support.
 It must be adjustable to a variety of
patients sizes and restorative
procedures.

19. Patient position

20. Points should be considered in
relation to patient position:
 The choice of patient position varies with the operator,type of
procedure,area of mouth involved.
 In general, head should not be lower than feet.but only in
emergency conditions.
 After completing procedure chair should be placed in upright
position,so that patient can leave the chair easily and
preventing undue stress or loss of balance.

21. Operator position
Proper operating positions and good posture reduce
fatigue and physical strain and possibility of developing
musculoskeletal disorders.
Most dental procedure can be accomplished while
seated,back and chest are held in upright position with
the shoulders squared which promotes proper
breathing and circulation .

22. Operating position
Considerations
 Proper balance and weight distribution on both feet is
essential when operating in a standing position.
 Operating positions may be described by the location of
the operator or by the location of the operators arm in
relation to patient position.

23. For a right handed operator there
are essentially 4 positions ,they
are:
 Right front ……7 o'clock
 Right ……9 o'clock
 Right rear ..….11o'clock
 Direct rear ……12 o'clock
 For left handed operator ,left front,left,left
rear ,and direct rear positions ,these are
referred as 5,3,1,and 12 o'clock
respectively.

25. Right front (7o'clock )position
1. It helps in examination of the patient
2. Working areas include
 Mandibular anterior
 Mandibular posterior teeth (right side)
 Maxillary anterior teeth

26. Right (9o'clock) position
 Working areas include:
1. Facial surfaces of maxillary right posterior teeth
2. Facial surfaces of mandibular right posterior teeth
3. Occlusal surfaces of mandibular right posterior teeth

27. Right rear (11 o'clock ) position
 In this position dentist sits behind and slightly to the right of the
patient and the left arm is positioned around patient head
 This is preferred position for most of dental procedures
 Most areas of mouth are accessible from this position either using
direct or indirect vision
 Working areas include:
1. Palatal and incisor (occlusal) surfaces of maxillary teeth
2. Mandibular teeth (direct vision)

28. Direct rear (12o'clock ) position
 Dentist sits directly behind
the patient and looks down
over the patient's head
during procedure
 Working areas are lingual
surfaces of mandibular
teeth

29. General consideration
 Patient head should be rotated according to need of operator
without hesitating
 Operator should maintain space between the patient as while
reading a book
 The operator never rest his hands on patient face
 The chest of the patient should never be used as a tray to keep
instruments
 The left hand should be free to use as retractor using hand mirror
