The document describes a dental cement and its physical and chemical properties. There is no mention of AI or ML in the intended use, device description, or performance studies.
No
This device is a dental cement used for permanent cementation of dental restorations and core build-ups, which are restorative rather than therapeutic functions.
No
The device is a dental cement used for permanent cementation of restorations and core build-ups, not for diagnosing medical conditions.
No
The device description clearly states it is a "dual cure resin cement" and describes its chemical composition and physical properties, indicating it is a physical material, 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 for the permanent cementation of dental restorations and root canal posts, and for core build-ups. These are all procedures performed directly on the patient's teeth and mouth.
- Device Description: The device is a resin cement used for bonding and building up dental structures. It is applied directly to the patient's tissues.
- Lack of Diagnostic Purpose: The device is a therapeutic and restorative material. It is not used to diagnose a disease, condition, or state of health. It does not analyze samples taken from the human body (like blood, urine, or tissue).
IVD devices are specifically designed to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Device Description
TopCEM Dual Cure Resin Cement is a versatile and ultimate dental dual cure (chemical and/or light cure) luting cement containing paste-paste of Base and Catalyst. The mixing ratio, based on volume, is 1 part base paste : 1 part catalyst paste. It is also a core build up material in syringes.
The principal organic components are mixtures of dental methacrylate resins (TEGDMA, EBPADMA and UDMA). The inorganic filler loading is about 40% by volume having particle size range of about 0.01 to 3 microns.
TopCEM Dual Cure Resin Cement is delivered in either two separated single syringes for Hand-mix or double-barrel syringes for Automix and comes in seven shades: TR (Translucent), A0 (Light+), A1 (Light), A2 (Medium), A3 (Dark), White Opaque) and Opaque (Universal Opaque).
TopCEM Dual Cure Resin Cement is radiopaque, allowing for easy identification on radiographs. It belongs to Type 2 Class 3 dual cure materials in accordance with ISO 4049. The curing mechanism of the predicate devices and subject device is polymerization of uncured methacrylate ester monomers. This reaction is caused by photo initiator and chemical polymerization initiator systems.

The indications of the subject device are all covered by that of the 510(k) cleared predicate devices. Based on the indications for use in comparison to predicate devices, the subject device has been shown to be safe and effective for its intended use and the minor differences in indications for use fall within the intended use of the predicate devices affecting neither the general intended use nor substantial equivalence. The subject device has similar technological characteristics as the predicate devices. As compared to the primary predicate device, the subject device is also available in Hand-mix model, which is having the Catalyst and Base resin cement pastes packaged into physically separated single syringes instead of being packaged into a double barrel syringe as for the Automix. The base and catalyst are mixed in a 1:1 ratio to form dual-curing cement, and it will not pose any new issues of the safety and effectiveness. Therefore, the minor differences in the delivery system affect neither the intended use nor substantial equivalence.
