Hydrofluoric Acid Etching Of Flexoceram Inlay Porcelain:

A Microscopic Study

This study was carried out to determine the hydrofluoric acid (HF) concentration and time most suitable to use with Flexoceram inlay porcelain which is a new product on the market. This study has shown that 10% hydrofluoric acid is effective in etching Flexoceram inlay porcelain and that this concentration produces optimum etch patterns at 90 seconds of acid etching. It has also shown that hydrofluoric acid preferentially attacks the interface between the glass and the leucite crystals of the material.
