Indications for Use
tenure 4G is intended to be used as a resin tooth bonding agent. It is used for composite bonding of porcelain and metals, as well as for desensitizing root, dentin or crown prior to impressions or temporaries.
Device Story
tenure 4G is a multi-purpose, self-cure dental adhesive system; consists of polymerizable dental monomer resins; two-part system mixed by clinician; forms leak and stain-resistant bonds between dental surfaces and restorations; used in dental clinics by dentists; applied to intraoral surfaces including porcelain, ceramics, metals, and tooth structure; provides bonding for direct/indirect restorations and desensitization of dentin/root surfaces; benefits patient by securing restorations and reducing tooth sensitivity.
Clinical Evidence
Bench testing only. Laboratory shear bond testing performed on porcelain, enamel, and dentin substrates. Results showed mean bond strengths (MPa) of 13.149 (porcelain), 12.768 (enamel), and 26.035 (dentin), demonstrating effectiveness comparable to or exceeding predicate devices.
Technological Characteristics
Self-cure, methacrylate resin-based adhesive system; contains acetone and ethanol solvents; total-etch technique; multi-purpose application; permanent contact, external communicating device.
Indications for Use
Indicated for routine direct and indirect resin composite bonding; porcelain, ceramic veneer, amalgam, precious and semi-precious metal bonding; indirect gold, porcelain, and ceramic inlay/onlay bonding; and desensitization of root, dentin, or crown prior to impressions or temporaries.
Regulatory Classification
Identification
A resin tooth bonding agent is a device material, such as methylmethacrylate, intended to be painted on the interior of a prepared cavity of a tooth to improve retention of a restoration, such as a filling.

#### Description of the Device
tenure * 4G is DenMat's next generation of its popular Tenure MPB System with greater bond strength and sensitivity control. It is a 40 generation multi-purpose, self-cure adhesive system for bonding any resin restorative to all intraoral surfaces. They are polymerizable dental monomer resins that are chemically-cured with the reaction initiated when the two parts are mixed together. These polymers form strong leak and stain resistant bonds between the dental surface and restorations placed over them.
#### Intended Use of the Device
tenure #G is intended to be used as a resin tooth bonding agent. It is used for composite bonding of porcelain and metals, as well as for desensitizing root, dentin or crown prior to impressions or temporaries.
#### Indications of Use of the Device
tenure 4G is recommended for the following types of applications:
- 1) All routine direct and indirect resin composite bonding.
- 2) Porcelain, ceramic veneers, amalgams, precious and semi-precious metals bonding.
- 3) Indirect gold, porcelain and ceramic inlays and onlays bonding.
- 4) Desensitization of root or dentin prior to impressions and temporaries.
- 5) Preparation desensitization of crown prior to impression or temporaries.
#### Substantial Equivalence Discussion
- 1) Intended Uses/Indications for Use
tenure 4G and the predicate devices are intended to be used as resin tooth bonding agents. They are used for composite bonding of porcelain and metals, as well as for desensitizing root, dentin or crown prior to impressions or temporaries.
tenure 4G and Tenure MPB are recommended for the following types of applications: all routine direct and indirect resin composite bonding; porcelain, ceramic veneers, amalgams, precious and semi-precious metals bonding; indirect gold, porcelain and ceramic inlays and onlays bonding; desensitization of root or dentin prior to impressions and temporaries; and preparation desensitization of crown prior to impression or temporaries.
ALL-BOND 2 applications include bonding to dentin, enamel, new or old composite, precious and non-precious casting alloys, silane treated porcelain, and new or old amalgam; and treatment of tooth sensitivity.
{5}------------------------------------------------
Scientific literature have been evaluated to determine safety and efficacy of similar products used for the same indications. The intended uses and indications for use of the subject device are substantially equivalent to those of the predicate devices.
- 2) Chemical Components/Safety
Chemical components in tenure 4G have been used in the predicate devices. Scientific literature have been evaluated to determine safety and efficacy of similar products used for the same indications. The predicate devices have not been a focus of any advisory notice or recalls according to the post-market adverse event reporting requirements in the United States. The conclusion can be made that the safety of the subject device is substantially cquivalent to those of the predicate devices.
- 3) Technological Characteristics/Effectiveness and Performance
There are no international standards concerning performance for these types of devices. Scientific literature have been evaluated to determine safety and efficacy of similar products used for the same indications. The physical/mechanical properties of tenure 4G were tested in the lab using R&D test protocols. Results of shear bond testing indicate that tenure 4G was as effective and performs as good as or even better than the predicate devices. The conclusion can be made that the effectiveness and performance of the subject device is substantially equivalent to those of the predicate devices.
#### Biocompatibility
The subject device is categorized as an external communicating device with contact to tissue/bone/dentin and is a permanent contact device. tenure "4G's chemical ingredients are equivalent to those of the predicate devices. All devices are made of materials with a long history of safe use. The predicate devices have not been a focus of any advisory notice or recalls according to the post-market adverse event reporting requirements in the United States. Accordingly. conclusion can be made that the subject device is substantially equivalent in safety to the predicate devices.
