Intended Use
Aquasil™ XLV Smart Wetting Impression Material is used as an impression material in a dual phase impression technique. It may also be used for precise duplication of models. Regular Set is used for capturing multiple unit impressions. It is suitable for all impression techniques where the operator needs an extra low viscosity material. Fast Set is used for capturing one preparation only (single unit crown); ideal for double arch dual phase techniques.
Device Description
AQUASIL™ XLV SMART WETTING IMPRESSION MATERIAL is an extra low viscosity. elastomeric impression material with excellent hydrophilic properties, dimensional accuracy. high tear strength, and resistance to permanent deformation. AQUASIL XLV IMPRESSION MATERIAL with "smart wetting" improves wetting both the tooth surface and the model detail reproduction. AQUASIL XLV SMART WETTING IMPRESSION MATERIAL is available in Regular Set and Fast Set. It is available in cartridge delivery. In developing the Regular Set and Fast Set, adjustments were made to the active ingredients as compared to the predicate device (K943574). These adjustments were made to obtain two speeds of the material with improved physical properties. The speed of the materials was adjusted by increasing the amounts of catalyst and retarder fluids over the predicate device. These changes improved the setting properties of the mixed impression material and allowed for two speeds of the same viscosity of impression material. Other changes were made to improve the flow property of the mixed impression material and the shelf stability of the product. AQUASIL™ XLV SMART WETTING IMPRESSION MATERIAL is a twopart (base/catalyst) hydrophilic viny|polysiloxane (VPS), impression material used to record the details of hard and soft surfaces of the oral cavity.

The document describes a traditional impression material and its chemical composition, with no mention of AI or ML technologies.

No.
This device is an impression material used to capture details of the oral cavity; it does not provide therapy or treatment.

No
The device is an impression material used to "record the details of hard and soft surfaces of the oral cavity" for dental impressions, not for diagnosing diseases or conditions.

No

The device is an impression material, which is a physical substance used to create molds of oral structures. It is not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to create impressions of the oral cavity for dental purposes (impression material, duplication of models). This is a physical process for capturing anatomical details, not a diagnostic test performed on biological samples in vitro (outside the body).
  • Device Description: The description details the material properties and how it's used to record physical details of the oral cavity. It doesn't mention any analysis of biological samples or diagnostic capabilities.
  • Lack of IVD Indicators: There is no mention of analyzing biological fluids, tissues, or other samples for diagnostic purposes. The device is used directly in the mouth to create a physical mold.

Therefore, Aquasil™ XLV Smart Wetting Impression Material is a dental impression material, not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The catalyst and base pastes and the mixed product were evaluated for cytoxicity. The mixed product was evaluated for dermal toxicity, for initation, and for mutagenicity.

The base pastes give a moderate cytotoxicity and the catalyst pastes were noncytotoxic. When mixed, the cytotoxicity persisted, but was recorded as a lower value than the value for Reprosil® Impression Material.

The mixed product was tested by the Ames Mutagenicity Test. Acute Dermal Toxicity Test, and the Hamster Cheek Pouch Imitation Study. The final product is non-mutagenic, non-toxic, and a non-irritant.

TRADE NAME: AQUASIL™ XLV SMART WETTING® IMPRESSION MATERIAL

TECHNOLOGICAL CHARACTERISTICS: All of the components of AQUASIL XLV SMART WETTING IMPRESSION MATERIAL have been used in DENTSPLY legally marketed devices.

Due to the similarity of the formulation of AQUASIL XLV SMART WETTING IMPRESSION MATERIAL to the predicate device (K943574), we believe that additional biocompatibility testing of the new impression material is unnecessary.

The predicate device. Aquasil Smart Wetting Impression Material, was evaluated and the reports can be found in K943574:

The catalyst and base pastes and the mixed product were evaluated for cytoxicity. The mixed product was evaluated for dermal toxicity, for initation, and for mutagenicity.

The base pastes give a moderate cytotoxicity and the catalyst pastes were noncytotoxic. When mixed, the cytotoxicity persisted, but was recorded as a lower value than the value for Reprosil® Impression Material.

The mixed product was tested by the Ames Mutagenicity Test. Acute Dermal Toxicity Test, and the Hamster Cheek Pouch Imitation Study. The final product is non-mutagenic, non-toxic, and a non-irritant.

As impression materials, AQUASIL XLV SMART WETTING IMPRESSION MATERIAL and the predicate device (K943574) are in the mouth for less than ten minutes.

We believe that the prior use of the components in DENTSPLY legally marketed devices, the similarity of formulation to the predicate device, the final product testing of the predicate device, the limited exposure time in the mouth, and the performance data outlined above support the safety and effectiveness of AQUASIL XLV SMART WETTING IMPRESSION MATERIAL for the intended uses.
