Safety
Warnings and Cautions
Always wear protective eye equipment
in order to avoid corneal abrasion or irritation if
particles are deflected into the eye. This applies to all personnel including the patient.
Use a rubber dam
for all operative procedures in order to avoid injury to gingiva or other
soft tissue. A rubber dam or latex matrix band is also required for interproximal
preparations to protect adjacent tooth surfaces.
In order to reduce the risk of embolism
never direct the handpiece toward an open pulp
chamber or at pulpal exposures
. Also
never place the handpiece in direct contact
with
the gingiva when the air is activated
. While the abrasive stream will not cut the gingival
tissue, it may irritate it.
The handpiece should be directed precisely at surfaces and tooth structures which are to be
modified or removed. The nozzle tip should be placed two (2) millimeters from the tooth
and angled toward the area to be removed or modified. Unlike the high speed handpiece,
the
Mach
4.0
and
4.1
handpiece nozzles cut only directly from the end, there is no side
cutting.
Always use your high volume evacuation system
when using the handpiece on the
Kreativ Models
Mach 4.0
and
4.1
.
Have the dental assistant place the high volume
evacuation system in close proximity to the operative site.
Do not attempt to service the unit beyond those described items in the maintenance
section.
Call your nearest Welch Allyn / Kreativ service representative
for advice.
The Kreativ Models
Mach 4.0
and
4.1
APB systems are designed for use only by and on
the order of a dentist.
