Diamond Bur

Diamond has high hardness and excellent physical and chemical properties. Adhering or electroplating the diamond grains with a certain acute angle in a certain direction and spacing with the central axis of the stainless steel bur as the center of the circle, it is made into a diamond car with a certain ability to cut hard tissue. Needle.

Tungsten steel bur

It is formed by vacuum high-temperature sintering or high-pressure molding tungsten carbide powder and cobalt powder welded on a steel rod, and is processed and trimmed by a large diamond grinding wheel. The resulting smooth surface of the tooth preparation allows for more precise impressions, resulting in more precise and tightly-margined all-ceramic restorations.

Tungsten steel burs meet the requirements for minimally invasive tooth preparation. The leveling performance of tungsten steel burs is good, and it is very suitable for the fine preparation of teeth, such as preparing grooves, barrel holes, dovetails, etc.

Model explanation

For easy understanding, the following models will take Mani diamond burs as an example:

T (Tapper) cone series: (full crown preparation)

TF (Tapper Flat): flat tapered, right-angled top, used for the preparation of shoulders for metal-ceramic teeth

TC (Tapper Cone): pointed cone, sharp tip, used for axial surface preparation

TR (Tapper Round): round head, rounded top, can be used for preparation of all-ceramic crown shoulder

F series:

FO: flaming apex, for occlusal and anterior lingual surfaces

S (Straight) straight/parallel series: no polymerization angle except SI, used for cavity preparation

SF: flat straight line, no degree of polymerization top right angle

SR: round head straight, no degree of polymerization top rounded corners

SO: Pointed straight, no degree of polymerization top 45 degrees

SI: Single Inverted Taper, Inverted Taper Drill

B(Ball) spherical series: ball drill

BC: Toroidal, ball drill with emery cuff

BR: spherical, ball drill without emery cuff

other:

DI: double inverted cone drill

CR: Inlay preparation series

CD: Children's Cavity Preparation Series

EX: special shape

WR: Disc
