Handpiece Service

Keywords: Stainless Steel, Sterilization, Cassettes

We offer three different categories of repairs for handpieces to accommodate every budget. By using different manufacturers and different types of bearings, we cover virtually the entire range of high speed handpieces on the market today. Keep in mind that rebuilding your handpiece turbine remains a strong alternative to replacement. These are the three options we offer:

  • new OEM (original equipment manufacturer) turbines
  • aftermarket turbines
  • your old turbine can be rebuild using all new Autoclavable bearings, seals, and O-Rings

Starting at $110.00


Due to their complexity low-speed handpieces, such as motors, heads and attachments as well as micro motors are repaired on a parts and labour basis.

  • new OEM (original equipment manufacturer) parts used
  • only the parts needed will be replaced
  • you will always be informed before any work starts
Regardless of Slow Speed or High Speed your handpiece will be lubricated, air/water purged, balanced and tested to ensure the highest quality. We service all major brands including Midwest, Kavo, NSK, A-dec, Healthco & Lares, Star and more!   Midwest

Yes we can manufacture a custom instrument for you.  Our technicians take pride in the fact they can create custom instruments. Please send us a the actual instrument and we can make a copy for you or you can take a photo of the instrument with a ruler beside it and we can work from that.  However, we do prefer the actual instrument.

All of our re-tipping is done by placing the new tips on to the handles using high pressure re-tipping. We do not use screw on re-tips. Re-tipping under high pressure ensures the tips are replaced on the handles to the same standards as that of a new instrument.

Yes we can put the exact same tips that you have on the handle or we can replace them with different tips. The choice is yours.

Normal repair work will be completed in around 2 weeks. Special work orders may vary.

No we cannot. The plastic handle would melt when heated to remove the tips

Insufficient drying either before or during sterilization: Thoroughly dry cassettes after cleaning, before wrapping. Crack open autoclave sterilizer door during dry cycle. Optionally after sterilization cycle, leave cassettes in warm sterilizer for 10 minutes
Improper loading of cassettes in sterilizer: Do not over pack sterilizer. Keep cassettes slightly separated within the chamber. Always use sterilizer's cassette rack

  • Insufficient rinsing after ultrasonic cleaning
  • Insufficient drying after ultrasonic cleaning
  • Sterilizer has not been cleaned
  • Rinse thoroughly under steady stream of water for 30 seconds
  • Rinse with hot water

Optional: Dip cassettes in alcohol after rinsing

Solution should be changed at least once a day

Sterilizers should be cleaned weekly

Use only distilled water for reservoir

Corrosion from carbon instruments spreads to stainless steel instruments
Separate stainless and carbon instruments
For carbon steel instruments: Dip in pre-sterilized rust-inhibiting solution as suggested by sterilizer manufacturer

Hand Scrubbing

  • Effective if performed properly
  • Increases chances for operator injury
  • Increases spread of contamination through splatter
  • Labour-intensive
  • Need proper care of scrub brush

Ultrasonic Cleaning

  • Safer than hand scrubbing
  • Effectively cleans all instruments
  • Reduces chances for spread of contaminants through splatter
  • Allows for more efficient use of staff time
  • Micro-organisms may accumulate in cleaning solution
  • Ultrasonic cleaning will not remove hardened Permanent cement. (Solution: remove cement while it is still soft.)

Automated Washer

  • Safer than hand scrubbing
  • Reduces chances for spread of contaminants of contaminants through splatter and aerosols
  • Allows for more efficient use of staff time
  • Effectively cleans instruments

  • Not all instruments are compatible with automated washers.
  • Please see manufacturer's instructions for detailed requirements.
  • All instruments need to be cleaned and thoroughly dried before they are sterilized. They should be washed with non-corrosive, low suds, neutral detergent.
  • Instrument cleaning can be accomplished by ultrasonic or automated cleaning, which is preferred to minimize the opportunity of sharps injuries due to hand scrubbing.

Dental-Mart Sales does not suggest the use of any abrasive brushes or materials to clean instruments.

  • Sterilization is a process that kills micro-organisms. There are three common methods of heat sterilization used in the dental office that can be verified by spore testing (steam autoclave, dry heat, and chemical vapour).

No we do not. However we offer $5 credit towards any new Dental-Mart instruments.

All manufacturing is performed at our Chicago, IL facility in the USA.
We will make a custom instrument for you as well.

Recycle any brand and any type of instrument (12) including:
- Scalers/Curettes
- Diagnostic Instruments
- Restorative Instruments
- Endodontic Instruments
- Surgical Instruments
- Piezo Tips
- Ultrasonic Inserts
- and MORE!
Plus receive $5 credit towards any new instrument

Amalgam left in carrier: Thoroughly empty amalgam carrier before returning to cassette.

If carrier is plugged, sterilize separately and unplug while carrier is warm

Chrome breakdown of instruments: Inspect instruments and replace those with cracked handles or peeling plating

Sterilizer has not been cleaned: Change reservoir water once a week. Regularly clean chamber and filters

Normal use discolouration: Every 6 months soak cassettes (without instruments and not in the ultrasonic) in 100% bleach for 5-30 minutes

Chemical attack on instruments
Rinse and dry instruments thoroughly
Use approved cleaning, sterilization solutions only.
Never use household bleach or stain and tartar remover

Stainless Steel Instruments

While stainless steel has superior corrosion resistance, it will discolour and corrode when exposed to higher than recommended chemical concentrations or certain chemicals.

Stainless steel should not be exposed to the following chemicals: Sodium Hypochlorite (household bleach), Tartaric Acid (stain and tartar remover), Aluminum Chloride, Barium, Chloride, Bichloride of Mercury, Calcium Chloride, Carbolic Acid, Chlorinated Lime, Citric Acid, Dakin's Solution, Ferrous Chloride, Lysol, Mercuric Chloride, Mercury Salts, Phenol, Potassium Permanganate, Potassium Thiocyanate or Stannous Chloride.

The following chemicals should


be used with stainless steel: Aqua Regia, Ferric Chloride, Sulfuric Acid, Hydrochloric Acid or Iodine.

Carbon Steel Instruments

Carbon steel instruments are more sensitive to chemicals than stainless steel and require special handling. Carbon steel should NOT be exposed to any of the previously listed chemicals for stainless steel. Separate carbon steel instruments from stainless steel instruments throughout the cleaning and sterilization process. If processed together, the carbon steel instruments will likely create cross-corrosion on the stainless instruments. Carbon steel instruments should be thoroughly dried prior to sterilization to prevent rusting and/or corrosion. Use a protective rust-inhibitor before sterilization.  

Hinged Instruments

All hinged instruments-forceps, rongeurs, scissors, pliers, hemostats, orthodontic pliers, etc.-should be kept lubricated. Regular use of proper lubricants, like Instrument Lubricant Spray (ILS), will prevent rust, corrosion and stiff joints and will ensure smooth operation. (Household lubricants and handpiece lubricants are NOT recommended.) All hinged instruments should be sterilized in the open position.  

Anodized Aluminum

Special care needs to be exercised in cleaning and sterilizing these coated aluminum instruments. Do not clean in an ultrasonic unit. Clean by hand or in an automated washer. Check processing product labels for caution about use with aluminum. Sterilize in autoclave, chemiclave or dry heat under 350°F (177°C) according to manufacturer's instructions. Note: Anodized aluminum instruments, when sterilized with stainless steel instruments, may cause an adverse chemical reaction.  

Ultrasonic Inserts

To clean, rinse thoroughly or, if you choose, fully immerse in a mild ultrasonic cleaning solution (pH 7-10.5). Daily Clean or Place in Ultrasonic unit for 7 to 10 minutes or 16-20 minutes if the inserts are in a cassette. Thoroughly rinse the insert or cassette with water (de-mineralized water is ideal) and dry completely prior to sterilization.
