Abrasive micro-sandblasting is a popular procedure used in the dental lab for increasing bonding strengths prior to repairing or cementing restorations. Treatment with the Optiblast II prior to bonding can increase the surface area of metals, porcelains, and composites up to 400% and greatly increase the resultant bonding strengths. The nonrecirculating design also makes quick and easy work of everyday micro cleaning and roughening tasks in the lab.
