Essentials of Preclinical Conservative Dentistry
Patient Positioning (Dental
Chair Requirements)
1.
To begin with, the patient should have
direct access to the dental chair. The chair
should be at a low height and the backrest
should be upright so that the patient can sit
comfortably (Fig. 8.1).
2.
The back of the dental chair should be
positioned at about 15° angle (slightly raised
above the parallel position) to the floor
(Fig. 8.2). Some dentists also favour the use of
position, which is at 45° to the floor (Fig. 8.3).
The angle at which the backrest is positioned
is dictated by the tooth to be operated upon.
3.
The backrest can be moved in between
the procedure as and when required after
informing the patient.
4.
This movement is usually done by the use
of a single button, either in the front panel
of the bracket table (Fig. 8.4) or in the foot
control of the dental chair.
