PROVISA CEM
PROVISA CEM is intended for the cementation of temporary crowns and bridges. PROVISA CEM is free of eugenol. After its removal, it will also not inhibit the polymerisation of a composite cement or composite filling material.
PROVISA CEM is a dental cement and is particularly intended for the cementation of temporary crowns and bridges. Such a temporary prosthesis is a necessity for the patient in the period between the preparation of the tooth (or teeth) stump, followed by the impression taking, and the placement and cementation of the final prosthesis. During this period of one week or more, the prepared tooth stump has to be protected against any damage. But also the occlusal relationship of the tooth stump versus neighbouring and antagonist teeth has to be kept unchanged in order to prevent articulation problems upon placing the final prosthesis. A temporary cement should offer sufficient retentive force to keep the temporary prosthesis in situ during the intervening week(s), but at the same time it should enable the dentist to take the prosthesis off without damaging the tooth stump and with no discomfort for the patient. PROVISA CEM is presented in the form of two pastes: a white paste, containing zincand magnesium oxide as the reactive components and a yellow paste, containing fatty acid dimer as the reactive component. Upon mixing homogeneously, controlled by a uniform light yellow colour, a smooth paste with the correct consistency is formed, that can be pressed into a thin, but sufficiently strong cement layer. Through a reaction between the metallic oxides and the fatty acid dimer, a chelatenetwork is formed, that makes the paste harden. The resulting cement is stable and strong enough but not too strong.
The provided text describes a dental cement, PROVISA CEM, and its 510(k) clearance. However, it does not contain any information about acceptance criteria or a study proving the device meets acceptance criteria.
The document is a 510(k) submission summary and an FDA clearance letter. These documents focus on establishing substantial equivalence to a predicate device and confirming the device's intended use and regulatory classification. They do not typically include detailed performance study results or specific acceptance criteria for the device itself.
Therefore, I cannot populate the requested table or answer the specific questions about sample sizes, ground truth, expert qualifications, adjudication methods, or MRMC studies, as this information is not present in the provided text.
