Dental laboratory sandblasters play a crucial role in surface preparation the dental industry by improving bond strength and enhancing the surface of restorations. Through the process of divesting the casting investment and increasing effective surface area, sandblasting creates a rougher surface that allows for better adhesion of dental materials, making it an essential tool for any dental laboratory when fabricating crowns, bridges, veneers, and metal frameworks.
Additionally, sandblasting can be used as a polishing technique, resulting in a smooth and aesthetically pleasing surface finish. Sandblasting media can be Aluminum Oxide, glass beads, walnut shells, or sodium bicarbonate.
What abrasive media size to use?
50 micron material is good for gentle oxide removal and framework preparation of precious metals.
110 micron material is good for surface conditioning of non-precious alloys, oxide removal, and divesting.
125 micron material is good for surface conditioning of non-precious alloys, oxide removal, and divesting.
250 micron material is good for heavy oxide removal.
