Possible Missing Part B Resin Prompts Recall of Keystone FP3D Resins 2026

Dental laboratories that 3D print flexible partial dentures may have received FP3D resin bottles that are missing a key component. Keystone Industries has recalled four FP3D resin products in Canada after some bottles may have been mis-filled during manufacturing and shipped without part B resin, according to a notice Health Canada published on October 21, 2026.

Health Canada classified the action as a Type II health product recall and assigned it identification number RA-82839. The recall date listed in the notice is October 9, 2026. The issue is categorized as a medical devices performance problem in the dental category.

Products Affected by This Recall

FP3D is a dual cure resin indicated for the 3D printed fabrication of flexible partial dentures in dental laboratories. Each unit is supplied in a 10:1 resin cartridge containing a part A resin and a part B resin. The recall covers four shades, and each one is tied to a single lot and catalogue number.

• FP3D Light Reddish Pink: lot 26AP7191, catalogue number 4230441
• FP3D Original Pink: lot 25GP6826, catalogue number 4230440
• FP3D Dark Veined: lot 25IP6936, catalogue number 4230442
• FP3D Original Opaque: lot 26GP7665, catalogue number 4230443

Health Canada lists Keystone Industries, of 52 West King Street, Myerstown, Pennsylvania, United States, as the company responsible for the product. The notice does not state how many units are affected, and it does not give UPC codes.

The Reason Behind the Recall

According to the notice, FP3D resin bottles may have been mis-filled during the manufacturing process and inadvertently shipped without part B resin. The wording is cautious: it says the bottles may have been mis-filled, not that every bottle in the listed lots is affected.

The product is described as a two-part system supplied in a 10:1 cartridge, so a bottle that left the facility without part B would not match the product as it is meant to be sold. Health Canada lists the issue as a performance problem. The notice does not describe injuries, patient complaints or test results, and it does not explain how the mis-filling was found.

Who Should Be Concerned

The notice lists healthcare and industry as the intended audiences. In practice, that points to dental laboratories and any other business that stocks or uses FP3D resin to fabricate flexible partial dentures. The product is meant for use in dental laboratories rather than for sale to the general public.

The notice does not say which provinces received the affected lots or how widely they were distributed in Canada. Anyone who has bought FP3D resin recently should compare the lot numbers printed on their bottles against the four lots above, rather than assuming their stock is unaffected.

Steps Consumers Should Take

The only action Health Canada lists is to contact the manufacturer if you need additional information. The notice gives no refund, replacement or return instructions and no phone number or email address, so those details would have to come from Keystone Industries directly.

• Check the lot number and catalogue number on every FP3D bottle in your inventory.
• Compare them with the four lots in this recall: 26AP7191, 25GP6826, 25IP6936 and 26GP7665.
• If you hold one of these lots, contact Keystone Industries for guidance on how to proceed.
• Ask the manufacturer what to do about any work already produced with a listed lot, since the notice does not address that.

Regulatory Response

Health Canada published the recall as a health product recall for medical devices in the dental category. The notice carries a Type II classification and the identification number RA-82839, and it shows the original published date and the last updated date as October 21, 2026.

The agency’s recall page also offers email notifications for new and updated recalls and safety alerts. Readers who work with dental devices can subscribe there to follow any updates to this notice, which could include more detail from the manufacturer.

For now, the facts in the public notice are limited. Four FP3D resin shades are involved, each in one lot, and the stated concern is that some bottles may have shipped without part B resin. Laboratories that use these products should verify their stock and get in touch with Keystone Industries for any further instructions.
