K011419, K051207, K013336, K023466, K032116 | | Device Description: | MARK3 alginate impression material is a dust free alginate
impression material with a creamy consistency for general
dental practice and for orthodontics. It is presented in the form
of a homogeneous pink colored powder with nice mint flavor.
The material has exceptional good elastic properties and a high
tear-resistance. The impression surface is smooth, which gives
excellent gypsum compatibility | | Intended Use: | MARK3 is an irreversible hydrocolloid dental impression material
used by the dentist for taking impressions of the oral cavity with
the purpose of constructing a gypsum cast that is a copy of the
situation in the mouth. It is a general purpose impression
materials for making study models, first impressions for the
construction of individual trays, situation models, orthodontic
impressions. | CAVEXY OUR IMPRESSION IS OUR CONCERN K141092 {4}------------------------------------------------ K141092 Image /page/4/Picture/1 description: The image shows a person wearing gloves and holding a small object, possibly a needle or similar tool. The background is a light blue color, creating a sterile or medical-like atmosphere. In the lower right corner, there is a logo that says "CAVEX" in blue and white lettering. #### Technical Characteristics: The technology for the proposed device MARK3 is comparable to the predicate devices. Basically the alginate, a soluble salt of alginic acid (extracted from brown seaweed), serves as the thickener for water, giving the paste, upon mixing, the correct consistency. It also reacts chemically with calcium sulphate to make the paste harden into a solid impression. The fillers (diatomaceous earth) give the mixture its mechanical strength and proper handling characteristics. A retarder, sodium pyrophosphate, is used for achieving the proper hardening-time. Sufficient working time to mix, apply and take a proper impression and short setting time in the mouth. Stabilizers will improve the surface-smoothness of the gypsum-cast and the pigment facilitates the "reading" of the impression by the dentist for a good judgment of its quality. Peppermint oil is added to overcome the "gagging" reflex which can occur during the impression taking. Paraffin oil is added in order to prevent dust formation during dosing and mixing of the powder. ## Performance Data: | Physical Parameters | Proposed device | ADA18

Testing is performed for cytotoxicity (ISO19993-5 ), sensitization and irritation (ISO10993-10). The test results demonstrated that the proposed device MARK3 is biocompatible. {5}------------------------------------------------ Image /page/5/Picture/0 description: In the image, a hand wearing a white glove is holding a needle. The background is a light blue color. In the lower right corner, there is a blue logo that says "CAVEX" in white letters. Conclusion: The technical characteristics, material composition, principles of operation and indications for use of the proposed device MARK3 alginate (K141092) is comparable to several secondary devices. Therefore, Cavex Holland BV considers the MARK3 Alginate Impression Material to be as safe, as effective and performance substantially equivalent to the predicate devices. eCopy Statement: The eCopy is identical to the paper copy Richard Woortman Manager Technical Services Cavex Holland BV --- **Source:** [https://fda-staging.innolitics.com/device/K141092](https://fda-staging.innolitics.com/device/K141092) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
