In the dental laboratory the material decides the instrument. Plaster, precious metal, cast alloys, zirconia and denture acrylic each call for a different blade or grit. This page sorts 457 laboratory instruments by material and by work step.
457 laboratory instruments in stock, ready to ship in 48 hours. Swiss made, ISO 13485 and CE-MDR.
| Material or work step | Instrument | Why this one |
|---|---|---|
| Finishing precious metal and cast alloys | Carbide burs | Cuts tough metal cleanly without smearing |
| Grinding plaster and dies | Carbide burs | Coarse cut removes quickly and does not clog |
| Working denture acrylic | Carbide burs | A blade, not a grain, otherwise the acrylic melts |
| Zirconia and all-ceramics | Sintered diamond grinders | Bonded grains stand up to the hard, brittle material |
| Layering and finishing ceramics | Ceramic grinders | Grit matched to veneering ceramic |
| Separating metal and ceramics | Separating discs | Thin cut with little loss of material |
| Milling CAD/CAM blanks | Milling tools | Shank for the milling machine, not for the handpiece |
| Working titanium | Carbide burs | Special cut against the smearing of titanium |
The rule is the same as in the practice, only the materials differ. Carbide cuts with defined blades and suits everything tough or smearing: precious metal, cast alloys, titanium, denture acrylic and plaster. Diamond grinds with bonded grains and suits everything hard and brittle: zirconia, glass and all-ceramics.
The practical difference shows in wear: a carbide bur dulls very quickly on ceramics, a diamond grinder clogs on soft acrylic. Pick the wrong instrument and you notice it not in the quality but in the service life.
The laboratory is dominated by the HP shank at 2.35 millimetres, the straight handpiece. The practice mostly works with FG shanks for the turbine. That is why practice instruments do not simply fit laboratory machines and vice versa.
| Code | ISO | Machine | Items |
|---|---|---|---|
| HP | 104 | Straight handpiece, 2.35 mm | 345 |
| HPs | 103 | Straight handpiece, short | 57 |
| CAD/CAM | 123 | Milling machine | 40 |
| Unmounted | 900 | To be mounted on a mandrel | 12 |
| RAL | 205 | Contra-angle, long | 3 |
HP stands for handpiece and denotes the straight shank of 2.35 millimetres that the straight laboratory handpiece takes. In the ISO code this is 104 at positions four to six. HPs with 103 is the same fitting in a short version. Of 457 laboratory instruments, 402 carry one of these two shanks.
As a rule no, because the shank does not fit. The practice mostly works with FG shanks for the turbine, the laboratory with HP shanks for the straight handpiece. Speed differs too: laboratory machines run slower and with more torque. An instrument with the wrong shank simply cannot be clamped.
Sintered diamond grinders. Zirconia is hard and brittle, so a carbide blade fails quickly. In sintered grinders the diamond grains sit not only in a galvanic layer but throughout the bond, which is why they stand up to the material longer. The range holds 96 such items.
A shank that does not belong in a handpiece but in the collet of a milling machine. In the ISO code it carries 123. Such tools mill blanks of zirconia, wax, composite or PMMA from a digital data set. The range holds 40 such items in the milling tools group.
Coarse cuts remove quickly and suit plaster, acrylic and initial shaping. Fine and cross-cut versions work more slowly but leave a smoother surface and chatter less. The cut sits at positions ten to twelve of the ISO code; the assignment per item is on the respective category page.
