The MicroEtcher™ IIA is a chairside/lab air abrasion unit designed to micro-etch and cleanse restorative and tooth surfaces using controlled abrasive delivery. It creates a consistent micro-retentive surface to support reliable adhesion during bonding, cementation, and restorative repair procedures.

Key benefits

• Optimizes bonding: micro-mechanical surface conditioning to enhance adhesion of restorative materials.
• Clinical control: precise, targeted abrasion for predictable surface preparation.
• Versatile workflow: suitable for intraoral procedures and extraoral/lab applications.
• Efficient prep: helps streamline repair and cementation steps by improving surface cleanliness and texture.

Common dental indications

• Surface conditioning prior to luting and cementation of indirect restorations
• Porcelain and restoration repair protocols (creating a retentive surface before bonding)
• Micro-etching of metals, composites, ceramics, and existing restorative materials
• Cleaning preparation surfaces and removing surface contaminants that may compromise bonding

Compatible with

• ALUMINIUM OXIDE 1lb 50 Micron (Danville) #15301
  50 µm aluminum oxide abrasive media commonly used with MicroEtcher systems for effective micro-etching and surface conditioning prior to bonding and repairs.
• MICROETCHER Hook-Up Kit (Danville) #44000
  Operatory connection kit that helps integrate the MicroEtcher IIA with your air source (quick-disconnect workflow) for a cleaner, more convenient chairside setup.
• MICROETCHER Male Quick Disconnect (Danville) #44020
  Quick-disconnect component used with compatible hook-up configurations—helps you connect/disconnect the MicroEtcher IIA from the air line efficiently.
• MICROETCHER Quick Disconnect (For Lab) (Danville) #44007
  Lab-oriented quick-disconnect option for bench setups—supports convenient air-line integration when the MicroEtcher IIA is used in a laboratory environment.
• MICROETCHER Handpiece Adapter 4–5 Holes (Danville) #44075
  Adapter designed to connect the MicroEtcher IIA to certain handpiece-style delivery configurations (4–5 hole systems), helping you integrate air abrasion into existing operatory setups.

Important notes

• Use 50 µm aluminum oxide for common bonding and repair indications unless your clinical protocol specifies otherwise.
• Confirm your operatory air pressure and follow manufacturer instructions for proper use, maintenance, and sterilization routines where applicable.

Tip: Adding the appropriate quick-disconnect accessories can speed up daily workflow and improve consistency during surface conditioning steps.
