what are the white stones and green stones?
What are Finishing burs used for?
Finishing Burs are used for finishing restorations, soft tissue recontouring, enamel and odontoplasty.
They can be obtained as 12 or 30 bladed burs in carbide or diamond heads in a variety of shapes.
Finishing burs are also available in White Stone for composite and Green Stone for amalgam.
Here I am going to talk about some features of dental stones. We can sort out 2two part-both in Dentistry and Laboratory.
First, what is white stone and Green Stone in dentistry?
Arkansas Stone, commonly known as white stone, is made of aluminum oxide grit, and consists of a head and shank.
They are ideal for fine contouring and finishing of enamel, composites, compomers, and porcelains. Available in friction grip (FG), handpiece (HP) and right-angle latch (RA). It comes in a variety of sizes and shapes.
Green Stone, is made of silicon carbide. Available in friction grip (FG), handpiece (HP), and right-angle latch (RA). There is round, cone, flame and so on, based on different head shapes.
The Recommended speed when you use
White Stone: recommended speed is 7,000-10,000/min
Green Stone: Green Stone burs must be run at a lower speed – less than 150,000 RPM
Second,what can they be used for in dental?
White Stone: White Stones are designed for contouring and finishing Enamel, Composites, and porcelains.
Green Stone: 1. In dental practice, Dura-Green stones are used for quick and simple contouring and finishing restorations made of all modern filling materials.
2.Dura-Green stones can be cleaned or customized to any individual shape with the Abrasives Dresser.
3. These hard stones can be used for adding surface characterization and adjusting fine details in restorations made from ceramics, composites, amalgam, and alloys.
4. Can be used for cutting, shaping, grinding, and for the removal of sharp edges, burs, and excess material.
In the Laboratory
There are three color types of stone: Green, Pink , and White Stone.
Green Stone, medium grit, can be used for Contour Ceramic. According to the shape of a head, can be divided into wheel shape, cylinder shape and so on.
Pink stone, medium grit, is good for Metal and Alloy.
White stone is used for Metal, Alloy composite
