The micro etcher IIA intraoral sandblaster is recognized as one of the most valuable tools for dentistry. It provides precise surface micro-roughening, improving bond strength up to 400 percent. Surface area and surface reactivity are dramatically increased for maximum bond. Sandblasting is fast and easy with most surface roughening procedures requiring only a few seconds. The micro etcher IIA offers all stainless steel construction, a replaceable Carbide tip, and a permanently affixed jar lid with a spill resistant abrasive filter. It is fully autoclavable (just remove jar and filter).
