About SDI Limited
SDI Limited tells its own history as a specialist dental-materials company founded in 1972. The about page says research, development, and manufacturing stay in Australia, with additional offices in Chicago, Cologne, and Sao Paulo. The head-office block on that page lists SDI Limited at 3-13 Brunsdon Street, Bayswater, Victoria 3153, with telephone +61 3 8727 7111.
The same page says SDI products are used in more than 100 countries and frames the work around minimal-intervention dentistry, including prevention and remineralisation. A composite brochure on sdi.com.au groups chairside restoratives under Luna 2, Luna Flow, Stela, Aura Bulk Fill, Aura Easy, and Wave, and it also lists a polishing paste.
Stela is described on a separate SDI page as a self-cure composite developed with researchers at the University of New South Wales, the University of Sydney, and the University of Wollongong. That page says Stela is made in Australia, is used with Stela Primer, and is offered in a capsule or an automix syringe. Indications listed there include Class I, II, III, and V restorations, base or liner, core build-ups, and sealing endodontic access cavities.
Amalgam remains on the current product list. The Lojic+ page calls the alloy a platinum-modified, high-silver, non-gamma-2 spherical amalgam and says it has been sold worldwide since 1988. A US product flyer also names Permite and GS-80 admix alloys and the Radii Plus LED curing light. Buyers should read the current instructions for use before treating any of those marketing lines as a clinical protocol.
Also known as SDI.
Key Offerings
Product and equipment lines dentists commonly associate with SDI Limited.
Luna 2
SDI's composite brochure describes Luna 2 as a universal nano-hybrid with nano and micron filler, a 77 percent filler load, and shades that include Vita shades, opaques, an incisal, and bleach shades. Indications printed there include anterior and posterior restorations, core build-ups, splinting, and repair of composite and porcelain.
Stela
SDI's Stela page calls this a self-cure composite meant as an amalgam alternative. The page says it does not require acid etching or a curing light, is used in two steps with Stela Primer, and comes in one universal shade in a capsule or automix syringe.
Lojic+
The Lojic+ product page describes a high-silver spherical amalgam in capsules, including one-spill, two-spill, and three-spill sizes and regular or fast sets. SDI says the alloy mixes for condensation, burnishing, and carving. Confirm mercury hygiene and local amalgam rules before ordering.
Radii Plus
A US SDI product flyer lists Radii Plus among LED curing lights and prints a high-intensity figure of 1500 mW/cm2 plus a five-year limited warranty. Compare that output claim with the light's current instructions and with the composites you actually cure.
Who SDI materials suit
SDI is a direct-restorative manufacturer, not a full operatory equipment line. A practice comparing packable composites, flowables, a self-cure bulk option, and capsule amalgam can read the universal composite guide and the flowable composite guide beside Luna 2, Luna Flow, and Wave.
Glass ionomers and whitening are also named in the US flyer. The glass ionomer guide and the desensitizer guide are the indexable pages to use when those categories, rather than amalgam, are the reason for the order.
How the lineup is split
Luna 2 and Aura Easy are light-cured sculptable composites in the brochure. Stela is the self-cure system and is the one SDI tells buyers not to etch or light cure. Mixing those instructions across products would be a handling error, so the IFU in the box should decide the steps.
Amalgam capsules still need a triturator. The amalgamator guide covers that equipment category. Radii Plus is a separate curing-light purchase and is discussed with other lights on the curing light guide.
What to confirm before ordering
Shade counts, filler percentages, and depth-of-cure statements on the composite brochure are manufacturer figures. Ask the dealer for the IFU revision that matches the lot you will receive, especially for Stela's no-etch claim and for Aura Bulk Fill's depth statement.
SDI prints Australian, US, and other regional phone contacts on the about page. US buyers should use the Chicago office details on that page rather than assuming the Bayswater toll-free number works outside Australia. Shipping, capsule size, and whitening regulations differ by country.

Questions buyers ask
Where is SDI manufactured?
SDI's about page says research, development, and manufacturing are carried out in Australia. The printed head office is 3-13 Brunsdon Street, Bayswater, Victoria 3153. International offices are listed in Chicago, Cologne, and Sao Paulo.
Is Stela a light-cured composite?
SDI's Stela page describes a self-cure composite used with Stela Primer. That page says the material does not need acid etching or a curing light and lists an unlimited depth of cure as a manufacturer claim. Follow the IFU shipped with the capsule or syringe.
Does SDI still sell amalgam?
Yes. The Lojic+ page and the US product flyer still list spherical and admix amalgam capsules, including Lojic+, Permite, and GS-80. Availability depends on the dealer and on local rules for dental amalgam.
Which buying guides match SDI?
Use the universal composite guide, the flowable guide, the curing light guide, and the amalgamator guide. Those pages compare categories. They do not rank SDI against other brands.
