What is it indicated for?
The AirPrep System incorporates the Micadent air abrasion system mounted inside the unit housing along with a membrane air dryer. The Micadent handpiece is mounted in a holder along the outside of the housing.
The Micadent is used to perform intra-oral air abrasion procedures including etching and preparing surfaces for composite restorations.
The AirPrep System is substantially similar in design and function as the Micadent manufactured by Hampton Research and marketed by Medidenta International. The Micadent will be supplied to ASI as a completed product. The AirPrep will be only marketed for the same purposes as the Micadent.
