7.  HOW TO USE

7.1  Before use

C A U T I O N

Do not impact this product (dropping, for example). If  the polisher gets an impact, stop using and ask your dealer for inspection 

and repair of  the main body and the powder cap together. If the main body and/or powder cap has got a crack (including a 

small crack invisible to the naked eye) through an impact, the main body may break and cause accidents.

A T T E N T I O N

1) 

2)  When using other products which are compatible (such as peripheral devices and instruments) to this product, observe 

instructions for use of such devices or instruments.

1) Opening the package

2) 

3) 

Clean with alcohol and sterilize in an autoclave according to instructions in “9. CLEANING AND 

STERILIZATION”.

A T T E N T I O N

1) 

2)  Do not lubricate this product. Lubricant will be mixed into the compressed air and cause powder clogging.

4) Checking your air compressor

containing moisture. For drainage and regular maintenance of your compressor, please refer to your air compressor’s instruction 

7.2 

1) Preparation of polisher

(a)  If  polisher is connected to a turbine hose, disconnect it from the turbine hose.

(b) Attach the head and powder cap to the chamber unit according to “7.3 Attaching head” and “7.4 Attaching powder cap”.  

2) Connection (for BA720K/W/S/B/N)

(a) 

(b) 

attached. (If you don’t have a pressure gauge, consult with your dental dealer.)

(c) 

3) Connection (for BA720M)

(a) 

each connection. (If you don’t have a pressure gauge, consult with your dental dealer.)

4) Air pressure setting

(a)  Turn off  the water supply of  your dental unit. Direct polisher 

to your cuspidor and depress your foot control to activate the 

dental unit.

(b) Adjust the air pressure of the unit until the gauge shows 0.25 

to 0.4 MPa (about 2.5 to 4.1kgf/cm

2

).

(c)  Detach the pressure gauge and polisher after pressure 

adjustment.

C A U T I O N

1) 

disconnected or powder being scattered.

2)  Never pull the handpiece out of your coupling while polisher is in operation. This may cause injury due to disconnection of 

the polisher (for ULTIMATE BA720K or BA720S).

3)  Never release your coupling from the handpiece while polisher is in operation. This may cause injury due to disconnection 

of  the polisher (for ULTIMATE BA720W, BA720B or BA720N).

4)  The head and powder cap must not be detached during operation. This may cause injuries due to instrument becoming 

disconnected, or powder scattering.

5)  The air pressure at the coupling must be set within 0.25 to 0.4 MPa (about 2.5 to 4.1kgf/cm

2

). Excess air pressure will 

damage tooth surface and cause patient pain. It may also cause trouble during use such as injuries due to instrument damage, 

or powder scattering.

7.3  Attaching head

1)  Polisher must be disconnected from a turbine 

hose of  dental unit when attaching and 

detaching the head. If  it is connected, 

2)

3)  If  water, oil, or powder adheres to head or 

inside the chamber unit’s coupling, wipe off 

with a cotton swab or dry cloth.

4)  Align the head to the thread of  the chamber 

unit’s coupling, turn the head in the direction 

of  the arrow in the illustration until it stops. 

7.4  Attaching powder cap

 *  Water due to sterilization must be expelled 

powder yet.

1)  The powder cap must be attached or detached when 

polisher is not connected to a turbine hose. If 

connected, detach from the turbine hose.

2)  If  water, oil, or powder adheres to inside chamber unit, 

powder cap, or powder seal, wipe off with a dry cloth.

3)

4)  Turn the powder cap in the direction of  the arrow in the 

cap lies within the range of  the mounting position mark. 

In case the triangle symbol lies outside of the mounting 

position mark, replace your powder seal with new one

which may cause powder scattering.

4)  Before each use, check if  the screw threads of the main body and powder cap have any damage such as wear, crack, 

deformation, etc. If  the main body or powder cap has a damage, do not use and ask your dealer for repair together.

5)  If  the triangle symbol on the powder cap lies outside of the mounting position mark while the polisher is in use, this may 

cause trouble like crack, damage or premature wear of  the threads of  the main body and powder cap.

Remove water, oil, or powder remaining in/on the head, coupling of  chamber unit, powder chamber, and powder cap. 

Otherwise, the powder will get damp and cause clogging.

A T T E N T I O N

Remove water or oil remaining inside of  your coupling (for BA720K/W/S/B/N) or on your Midwest 4-hole turbine hose (for 

BA720M) and those on the joint of  the chamber unit. Otherwise, the powder will become damp and cause clogging.

2) Connection (for BA720K/W/S/B/N)

(a)  Connect a coupling (separately sold) 

compatible with your polisher to your turbine 

hose.

(b) Insert your coupling on your turbine hose into 

the joint of  polisher until you hear a locking

1) 

2)  Direct the nozzle to your cuspidor. Depress your foot control 

without water supply from the dental unit. Run for 1 minute 

to remove water remaining in the channels of  polisher.

A T T E N T I O N

Run polisher for 1 minute without powder before use. If  water remains inside of  the main body, powder will become damp and 

cause clogging.

or powder cap, remove it with a dry cloth.

5)  Fill sodium hydrogen carbonate powder not exceeding 15 g 

into the powder cap.

 *  The powder must be placed into the powder 

cap. Take care not to spill the powder over the 

thread of the powder cap. If the powder is spilt 

over the thread, wipe it off with a dry cloth. 

Filling too much powder will make the powder 

adhere to the powder seal and cause 

premature wear of the powder seal or 

incomplete sealing.

6)  Hold the chamber unit downward and the powder cap 

upward as shown in the illustration. Turn the powder cap in 

the direction of  the arrow until it stops.

7.9  Treatment

1) Patient, operator, and assistant protection

(a)  Operator and assistant must be wear protective eyewear and anti-dust mask.

(b) Protect the patient’s face (other than oral cavity) with towels or protective eyewear.

 *  If the patient wears contact lenses, the patient must remove them before treatment.

(c)  When spraying into an area around soft tissues such as gingiva, protect it with cotton in advance.

C A U T I O N

1)  When using, the operator and assistant(s) must wear protective eyewear and anti-dust masks full-time. If  the powder gets 

into your eyes, wash your eyes with water and consult an eye doctor.

2)  During a treatment with polisher, protect the patient with towels or protective eyewear so that the powder does not enter 

mucous membranes (eyes, nose, tracheae) other than intraoral.

2) Spraying

Make your vacuum suction system ready to remove scattered powder. Direct the nozzle to tooth surface and depress your foot 

control to start spraying.

 *  The prevention ability of tooth against discoloration is decreased after cleaning. Instruct the patient 

not to smoke or have foods or beverages with strong coloring effect such as tea and coffee for two 

or three hours after treatment.

 ○ 

 ○  Keep distance of  2 to 5 mm from the tooth surface.

 ○  Spray from gingival margin to occlusal surface. Suction the spray with your vacuum suction system and avoid soft tissues.

 ○  When cleaning a large area, spray while moving the nozzle minutely.

 ○  The powder may be sprayed for a few seconds after releasing your foot control due to the residual pressure within the powder 

chamber. Collect the powder with your vacuum suction to avoid damaging soft tissues.

 ○  Have the patient wash out his/her mouth as needed or after treatment.
