The document discusses the proper positioning of the dental chair and patient for various dental procedures. It recommends that the chair be adjusted so that the patient's head, neck and trunk are in a straight line to avoid strain, and that the chair be tilted back at a 45-60 degree angle for maxillary procedures and kept more upright for mandibular procedures. It also provides guidance on where the dentist should stand in relation to the patient for different quadrants and procedures. Finger rests are also described to provide support to the dentist for various dental extractions and procedures.

3. INTRODUCTION
The position should be comfortable for the patient and
surgeon
It should allow the surgeon to have maximum control of
the forces delivered through the forceps
It should provide better stability and support to the
surgeon
The dentist’s arms are close to his body when he places
the forceps on the tooth and the force is delivered from
the arm and shoulder with the wrist being steady in
position. This enables a successful extraction

• 6 inch below the

MANDIBULAR
TEETH

6. CHAIR POSITION OF THE PATIENT
 The chair is adjusted such away that the head ,neck and
trunk are in one line,this will nullify any strain caused by
stretching it backward or pushing it forward
For maxillary extraction chair should be tipped back so
that the maxillary occlusal plane is at an angle between
45 and 60 degrees to the floor
Raising the patient’s legs at the same time helps to
improve the patient’s comfort

7. For mandibular extraction ,the patient should be
positioned in a upright position so that when the
mouth is opened widely, the occlusal plane is
parallel or at 10 degree to the floor.

8. POSITION OF THE OPERATOR
The dentist should stand infront of the patient for
extraction in all quadrants except for the 4th quadrant
The dentist should stands on the right side of the patient
during all procedures
For mandibular right quadrant ,dentist may prefer to
stand behind the patient for the extraction and support
the jaw with the other hand coming across the patient ‘s
head from the left side

11. CHAIR POSITION IN SITTING POSITION
For extraction of maxillary teeth the patient is placed in
reclined position
The chair should be lowered at the level of dentist’s
elbow
For mandibular extraction the patient is reclined
position
Dentist performs right quadrant extractions sitting
behind the patient
For all other quadrant sitting infront of the patient
