Introduction

The Kreativ Mach 5.0 and Mach 5.0 PLUS systems are compact, highly reliable, state­of-the-art instruments designed for Air Abrasive MicroDentistry. They are designed as
a means of removing tooth structure and other materials to prepare teeth for restoration,
and as an adjunct to the high speed dental handpiece and bur. These instruments were
developed after extensive consultation with dentists in order to provide the optimum
performance, taking into consideration patient comfort and the time constraints faced by
today’s 21st Century dental office.

Chapter

Note: Clinical use of the Kreativ Mach 5.0 and Mach 5.0 PLUS air abrasion systems
for procedures not included or suggested in this instruction guide is not advised.
Similarly, the Kreativ Mach 5.0 and Mach 5.0 PLUS systems should be only used by
dental professionals who have practiced on extracted teeth and who are thoroughly
familiar with this manual.

Purpose of this Manual

This manual should be thoroughly studied before installing and using the equipment.
Please call your nearest authorized Welch Allyn / Kreativ service representative if you
need additional information regarding installation, operation, or service of the instrument.

Information essential to the installation, operation, and routine maintenance of the Mach

5.0 and the Mach 5.0 PLUS devices manufactured by Kreativ, Inc., is included in this
manual. The instructions are written specifically for personnel who have been trained in
restorative and preventive dentistry.

A full selection of abrasive powders and nozzle sizes are available from your nearest
Welch Allyn / Kreativ sales representative. See the listing of supplies in Chapter 8.

All serviced components, such as control valves and hose connections, can be easily
accessed through the side doors of the instrument. A footswitch is provided to start the
powder flow. The instrument features a mixing chamber which can be quickly unloaded
in order to facilitate service, changing abrasive powders, or cleanup of the unit after use.

2. Safety

2

The Kreativ Mach 5.0 and Mach 5.0 PLUS systems are designed for use only by and
on the order of a dentist.

Warnings

Always wear protective eye equipment in order to avoid corneal abrasion or irritation if
particles are deflected into the eye. This applies to the dentist, staff, and patient.

A rubber dam is recommended in order to avoid injury to gingiva or other soft tissue,
and for interproximal preparations to protect adjacent tooth surfaces.

AND OTHER SPECIFIED HAZARDS ONLY

IN ACCORDANCE WITH CAN/CSA C22.2 NO. 601.1

21ZJ

Chapter

Never direct the handpiece to an open pulp chamber or at pulpal exposures. Also
never place the handpiece in direct contact with the gingiva when the air pressure is
activated. While the abrasive stream will not cut the gingival tissue, it may irritate it.

All Kreativ Mach 5.0 and Mach 5.0 PLUS accessories which come into contact with
the patient should be sterilized prior to each use. Always disinfect the handpiece cradle
in the remote control unit before each patient use.

Always use your high volume evacuation system when using the handpiece of the
Kreativ Mach 5.0 or Mach 5.0 PLUS. Have the dental assistant place the high volume
evacuation system in close proximity to the operative site.

Make sure that the Kreativ Mach 5.0 and Mach 5.0 PLUS systems are connected to a
properly grounded electrical outlet.

Always replace fuses with fuses of the proper rating, as indicated in the Chapter 1.

Cautions

For dental cleaning (prophylaxis) procedures, be absolutely sure that the
chamber and hose have been completely cleared of all abrasive powders and use
only bicarbonate in the chamber.

Page 8 990008 Rev. H

The handpiece should be directed precisely at surfaces and tooth structures which are
to be modified or removed. The nozzle tip should be placed a few millimeters from the
tooth and angled toward the area to be removed or modified. Unlike the high speed
handpiece, the Mach 5.0 nozzle cuts only directly from the end; there is no side cutting.

Do not attempt to service the unit beyond those items described in the maintenance
section. Call your nearest Welch Allyn / Kreativ service representative for instructions.

Practice on extracted teeth prior to utilizing the Mach 5.0 and Mach 5.0 PLUS on
patients. Begin with the 27.5 micron aluminum oxide powder. Use only short bursts,
carefully monitoring your progress. Most users prefer the 27.5 micron powder at a
Particle Energy setting of 50 to 80 psi due to improved patient acceptance.

Do not substitute non-Kreativ, Inc., materials or accessories. Use of materials or
accessories supplied by other manufacturers may result in damage to the unit and will
void the factory warranty.

Use only clean dry air. Make sure that your air compressor system utilizes air dryer
filter systems and that they are fully operational. Any moisture or oil in the air supply
will adversely affect the performance of your Mach 5.0 or Mach 5.0 PLUS.

When using the Mach 5.0, check to be sure that your air system produces at least the
minimum pressure and flow rate indicated in the Air Requirements section of the
Specifications in Chapter 1.

Sound clinical judgment, good common sense and proper training are essential to the
successful use of the unit in order to provide safe and efficient patient care.

Always follow “standard of care” protocols in performing dental operative procedures.

The handle on the top of the Mach 5.0 PLUS units is intended to be used to pull the
units and is not meant for picking up the units.

Caution: Connecting the instrument’s input air supply line to a water outlet will
lead to damage to the instrument which is not covered under the limited
warranty. Repairs for such damage are at the customer’s expense.

3. Controls and Connectors

3

The diagrams on the following pages illustrate the external controls, indicators, and
connectors for the Kreativ Mach 5.0 and Mach 5.0 PLUS instruments.

In both the Mach 5.0 and the Mach 5.0 PLUS, the handpiece hose connects to a
connector located under the Control Module.

The Control Module is removable from the front of the Mach 5.0 and the Mach 5.0
PLUS and can be attached to the Dental unit, as follows:

1. The Control Module is held to the front of the instrument by spring tension on the
interconnecting cable. With the handpiece mounted in the cradle on top of the
Control Module, the hose and the provided extension cable allow the Control
Module to be remotely located up to 10 feet from the main unit. The connector to
the air supply is located on the rear of the instrument.

Chapter

2. A mounting plate with clamp is supplied with the Mach 5.0 and the Mach 5.0
PLUS, to be mounted on the dental unit.

3. The Control Module will attach to the mounting plate for use at the dental unit,
remotely from the main instrument.
