Device Story
Bright Impress is a vinyl polysiloxane (addition-reaction silicone) dental impression material. Available in five viscosities (Light, Medium, Heavy, Bite, Putty), it is used by dental professionals to capture precise anatomical details of teeth and oral structures. The material is applied to the oral cavity via tray or syringe; it sets to form a stable, accurate negative replica of the dental anatomy. These impressions are used to fabricate crowns, bridges, dentures, and orthodontic appliances. The device provides high hydrophilicity, dimensional accuracy, and tensile strength to ensure reliable clinical outcomes. It is a non-sterile, prescription-only dental material.
Clinical Evidence
Bench testing only. Performance evaluated against ISO 4823 and DIN 13903 standards. Metrics included consistency, working time, detail reproduction (20-75μm), linear dimensional change (≤1.5%), elastic recovery (≥96.5%), strain in compression, hardness, and flexural strength. Biocompatibility testing (cytotoxicity, sensitization, irritation, systemic toxicity) performed per ISO 10993.
Technological Characteristics
Material: Vinyl polysiloxane (addition-reaction silicone elastomer). Form factors: Light, Medium, Heavy, Putty, and Bite viscosities. Standards: ISO 4823 (impression materials), DIN 13903 (bite registration), ISO 10993 (biocompatibility). Non-sterile. Standalone dental material.
Indications for Use
Indicated for dental impression procedures including inlay, onlay, crown, and bridge preparations, functional impressions, denture impressions, and study models in human patients.
Regulatory Classification
Identification
Impression material is a device composed of materials such as alginate or polysulfide intended to be placed on a preformed impression tray and used to reproduce the structure of a patient's teeth and gums. The device is intended to provide models for study and for production of restorative prosthetic devices, such as gold inlays and dentures.

Dear Woojung Park:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's
{1}------------------------------------------------
requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see
