Tokuyama Dental.

Tokuyama Dental America's about page says Tokuyama Dental is a subsidiary of Tokuyama Corporation and that dental products are made in Japan. It describes the parent as a chemical and silicon manufacturer with more than 5,800 employees and plants in more than one country. The dental site's 2009 note says Bond Force launched that year as a single-step self-etch adhesive. The homepage separates that adhesive from a later universal bond.

Estelite Sigma Quick is the composite name on the product page, with spherical filler and a stated 82 percent filler by weight. Shade and cure time are on the instructions, not in this summary. Bond Force is the adhesive the company points to first, with an IFU that limits use to licensed dentists and warns that the liquid contains methacrylic monomers and is flammable. Those precautions are why the IFU exists. A blog summary is not enough to place it.

The U.S. site does not, in the pages reviewed, print a street address for the American office. Order through the distributor the site names and keep the IFU that matches the bottle, pen, or unit dose. Bond Force is sold in more than one package. The chemistry is the same family. The dispensing well cleaning step in the IFU still applies.

Tokuyama's claim is control of research and manufacturing inside the chemical company. That is their quality argument. It does not rank Estelite against every other universal composite. Use the adhesive and composite guides for the category, then the IFU for the bottle.

Tokuyama suits a restorative practice that wants a spherical-filler composite and a single-bottle self-etch adhesive from one Japanese manufacturer. The universal composite guide and the adhesive guide are the category pages. A lab milling zirconia is not the Bond Force buyer unless the dentist is repairing porcelain, which is an IFU indication.

Offices that always etch enamel can still use Bond Force. The marketing page says selective enamel etch is allowed. Total-etch habits and self-etch habits should not share one undocumented shortcut.

Unit-dose versus bottle is an infection-control choice. The IFU says not to reuse the disposable applicator.

Shofu Beautifil and Pulpdent ACTIVA are other direct restoratives. Estelite's story is spherical filler. Theirs are different. Compare handling in the composite guide, not by the adjective on the homepage.

Bond Force is self-etch. A fourth-generation etch-and-rinse system is a different protocol. Do not mix bottles from two generations in one setup without a written reason.

The universal bond on the homepage is a later product. If your notes say Bond Force, do not let a rep substitute the universal bottle without telling the doctors.

Match the light. The IFU says a camphorquinone-range light, peak around 470 nm, cures Bond Force. Confirm your curing light is in that range. Ten seconds is the marketing page's cure time. The IFU governs if they differ.

Allergy precautions are in the IFU: methacrylates, eye contact, flammability. That is a safety sheet, not optional reading.

Ask the U.S. distributor for shelf life and for which Estelite shades are stocked. The 82 percent filler figure is the product page's. It is not a clinical wear study.
