The summary describes traditional silicone impression materials and their physical properties. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
No
The device is used to take anatomical data of the patient's mouth to diagnose problems, define required interventions, and/or check their effectiveness, but it does not directly treat or cure any medical condition.
No
The device is an impression material used to take anatomical data of the patient's mouth, which then helps realize a plaster mold for diagnosis. The material itself is not diagnostic; it's a tool in the diagnostic process.
No
The device description clearly states that the device is a physical material (silicone impression material) provided in jars and cartridges, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body for the purpose of providing information for the diagnosis, treatment, or prevention of disease.
- Device Function: The Lascod impression materials are used to create a physical mold of the patient's mouth. This mold is then used by the dentist to diagnose problems, define interventions, and check their effectiveness.
- Lack of Specimen Examination: The device itself does not perform any examination or analysis of a specimen taken from the body. It is a tool used to create a physical representation of the anatomical structure.
- Purpose: The primary purpose is to capture anatomical data for subsequent use in diagnosis and treatment planning, not to directly diagnose through the analysis of a biological specimen.
While the resulting plaster mold is useful for diagnosis, the impression material itself is a physical material used to create that mold, not a diagnostic test performed on a biological sample.

Device Description
Lascod Impression Materials are addition-curing polyvinylsiloxane silicones. They exhibit excellent accuracy, maximum thixotropy, and hydrophilicity. Additional elastomeric properties include, fast in the mouth setting time, high resistance to tear, dimensional accuracy, and resistance to permanent deformation. The Lascod impression material product line boasts multiple different variants: hard and soft putty; heavy, regular, light and superlight body – all putties and bodies, are available both as normal and fast set; mono and bite. Putties are provided in 300 or 150 ml plastic jars. The body and the bite product lines, are usually offered in the standard (1: 1) 50 ml dual barrel cartridges. The Mono product line is provided in two forms; a standard (1: 1) 50 ml dual cartridge, and a (5: 1) 380 ml, large dual cartridge.

7. Device Description
Lascod Impression Materials are addition-curing polyvinylsiloxane silicones. They exhibit excellent accuracy, maximum thixotropy, and hydrophilicity. Additional elastomeric properties include, fast in the mouth setting time, high resistance to tear, dimensional accuracy, and resistance to permanent deformation. The Lascod impression material product line boasts multiple different variants: hard and soft putty; heavy, regular, light and superlight body – all putties and bodies, are available both as normal and fast set; mono and bite. Putties are provided in 300 or 150 ml plastic jars. The body and the bite product lines, are usually offered in the standard (1: 1) 50 ml dual barrel cartridges. The Mono product line is provided in two forms; a standard (1: 1) 50 ml dual cartridge, and a (5: 1) 380 ml, large dual cartridge.
8. Performance testing and Shelf Life
Lascod Impression Materials have been tested and are compliant with the requirements of ISO 4823:2015 "Dentistry Elastomeric Impression Materials." Shelf Life testing demonstrated that the silicones could be stored for three years. The performance requirements that Lascod Silicones comply with are provided in Table 1.
9. Biocompatibility testing
The FDA guidance "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process" was used to determine biocompatibility testing requirements. Cytotoxicity, Irritation, and Sensitization testing conducted demonstrate that the Lascod Impression Materials are biocompatible.
10. Substantial Equivalence
Lascod Impression Materials have identical intended use and highly similar indications for use as the predicate device. Biocompatibility testing demonstrated that both predicate and subject devices were safe for intended use. Performance testing demonstrated that both subject
