Micro-Etchers and Intraoral – sandblaster

Micro-Etchers and Intraoral – sandblaster that is crucial in today’s bonded world.

Micro-etching is commonly used in the laboratory, but less intraorally.

Using the Micro-Etcher intraorally can increase bond strength by up to 400%, according to various studies.

It can be used on enamel, dentin, and any other substrate in the mouth where bonding is needed.

Our new CA-1 Micro-Etcher connect directly onto your standard 4- hole hose.

The CA-1 Micro-Etcher can be used with all sizes of aluminium oxide, sodium bicarbonate, (which removes excess resin without enamel erosion), or glass beads.

The CA-1 Micro-Etcher can be used for:

  • sclerotic dentin etching on Class Vs,
  • pit and fissure stain removal prior to placing sealants,
  • porcelain and PFM restoration repairs, and
  • removing old cements on prepared teeth prior to re-cementation.

It is simple and fast to use.

It is even autoclavable.

Once you have a Micro-Etcher around, you will find all sorts of uses for it.

When preparing a restoration for adhesion, sandblasting cleans and etches the surface using micro-mechanical abrasion which results in an improved bond strength for subsequent applications.

The CA-1 Micro-Etcher design incorporates a precise and ergonomic handpiece with:

  • 360-degree rotatable head
  • Removable head for easy cleaning.
  • Standard 4- hole design
  • Unique external multi-point air-and-water nozzles
  • Negative pressure design – No clogging – No back Suction
  • Tungsten Nozzles

Bonding to Zirconia?

Resin cement bonds to the phosphate sites available on zirconia.

During try-in procedure of a zirconia crown, saliva contaminates (complicated to be avoided) the zirconia and occupies these phosphate sites on zirconia.

These sites are no longer available for cementation and only sandblasting releases up those sites for bonding.
