Monolayer PMMA discs
Monolayer PMMA discs carry a single shade through the whole disc, which suits provisionals and try-ins where a uniform colour is acceptable and the piece will be replaced. The source catalogue lists an Amann Girrbach monolayer PMMA disc, and the Amann Girrbach name appears there as a third-party system reference, not as a company brand or partnership. A laboratory choosing a monolayer disc should note the disc size and the shade it needs, and confirm both in an inquiry, because stocked shades change more often than catalogue categories.
Monolayer discs are also the simplest PMMA choice to mill and finish, because there is no gradient to nest and no shade zone to place. That simplicity matters for a provisional that will be tried in the mouth and then replaced, where speed and fit outweigh aesthetic layering. The PMMA selection guide compares monolayer with multilayer discs in more detail, and it keeps the comparison at the level of planning directions rather than measured results.
Multilayer PMMA discs
Multilayer PMMA discs carry a shade gradient inside the disc, like their zirconia counterparts, so a provisional can already show a layered appearance before any staining. That gradient suits a provisional that will be worn for longer, or shown in the anterior region, where a flat single shade would look unnatural even for a temporary. The company catalogue lists multilayer PMMA discs as a category, described here in those terms. Ask for the shade-range figure in an inquiry.
Nesting matters for multilayer PMMA discs for the same reason it matters for multilayer zirconia: the shade of the finished piece depends on where the design sits inside the disc. A laboratory new to gradient PMMA should discuss nesting in its first inquiry, naming the software it uses, and test a single disc before committing to a quantity. The PMMA selection guide covers that point alongside the monolayer comparison.
Super hard PMMA block and pink PMMA disc
Two further named PMMA products appear in the source catalogue: a super hard PMMA block and a 3ST pink PMMA disc, the latter also listed with veins in its description. The super hard block suits work where a harder provisional material is wanted, and the pink disc suits gingiva-coloured work; both are described in those general terms only. Ask for the specification table for either product in an inquiry. A buyer who needs a hardness, shade or size figure for either product should ask for it by name in an inquiry.
The pink disc deserves a note on its own, because its colour is functional rather than decorative: it mimics gingiva for provisionals that show gum tissue, and the veins in its description suggest a natural tissue appearance. That is a planning hint, not a clinical claim, and a laboratory should confirm the shade and the disc size against the case before ordering.
PMMA in the laboratory workflow
PMMA work usually sits at the start of a case: a provisional while the definitive restoration is made, a try-in to check fit and shade, or a prototype to test a design before milling the final material. That position means PMMA orders are often smaller and more frequent than zirconia orders, and the inquiry for a PMMA disc should therefore name the case it supports, not just the disc. A company that knows the provisional's purpose can advise on the disc size and shade choice more usefully than one that only sees a product code.
Milling PMMA also has its own consumable needs, including PMMA burs listed in the tools range and dust extraction suited to PMMA milling. The tools index and the vacuum cleaner page cover those items, and a laboratory ordering PMMA for the first time may want to confirm the bur and extraction combination in the same inquiry. That single message can then cover the disc, the bur and the extraction question together.
PMMA figures to confirm in an inquiry
Ask for the wear result, fracture result, shade stability period and strength figure for the exact PMMA product in an inquiry. PMMA is a provisional material, and its performance depends on the case, the design and the time it spends in service, none of which a catalogue page can fix in advance. A laboratory that needs a performance figure for a particular provisional should ask for it in an inquiry, naming the product and the intended service period.
Certificates for PMMA follow the site-wide rule: they are available upon request, and no certificate number or scope is printed for any PMMA product. A buyer who needs a document for a particular market should name the product and the market, and the document supplied in reply can be checked against the actual requirement, which a printed certificate name alone could never show.
How to order PMMA discs
An order should name the PMMA product, the disc size, the shade approach and the quantity range, and then confirm the minimum order quantity, lead time, shipping method and payment terms as buyer instructions. Those four confirmations vary by order and destination, and this site does not promise them in advance. A laboratory ordering for a provisional should also note the case it supports, so the company can confirm that the disc size and shade match the intended use.
A first order of a small quantity for testing is sensible for a PMMA disc the laboratory has not used before, because fit and finish can be checked on a provisional before the disc becomes a regular stock item. The inquiry form has room to describe that test plan, and a company that knows it is a test order can advise on the disc choice that will make the test most informative. The form asks only for a name, an email address and the message.
