This microetcher sprays 40 micron aluminium oxide powder from a fine nozzle. It is used to clean and prepare the surface of a tooth, crown, denture or any other surface prior to bonding. The benefit is its ability to increase micromechanical bond strength.

What’s good about it

When preparing a surface for bonding, the microetcher cleans and etches using mechanical abrasion. It also greatly increases the surface area, creating an etch-like frosty appearance.

In the past, when bonding a crown with failed cementation, I used an ultrasonic cleaner to remove all remnants of the old cement. Now, with the microetcher, the gold surface is cleaned and etched for increased micromechanical bond prior to re-cementation.

When removing an amalgam filling, staining is quite often present on the exposed enamel surface. Rather than remove excess enamel with a diamond bur, the microetcher allows for conservative cleaning of the surface prior to bonding.

A microetcher is a device that’s used on a daily basis. It requires almost no maintenance and will most likely last you all your days of practice.

What’s not so good

When used intra-orally, you end up with fine dust all over the patient’s mouth, face and clothes. Suction is fairly ineffective at preventing this.

Where did you get it

  1. I agree with the comments. This is a great product. And yes it is available from Amalgadent in Australia. An alternative and much faster source, from my personal experience (5 days delivery from the U.S. instead of 2 months from Australia) is Henry Schein in America. Just order online, they deliver to Australia.

    • Hi Josh,

      We would strongly recommend against people doing that unless they have approval from the TGA. If a dentist is going to import a product to use in someone’s mouth, and that product doesn’t have TGA approval, that dentist would be breaking the law.

      All the best

  2. What do you do about the mess it creates intraorally? Does it cause harm to patients?
    What is the protocol in using it intraorally? Do you need to get any other attachments to use it intraorally efficiently.
