Intended Use

S.I.N. Dental Implant System is intended for placement in the maxillary or mandibular arch to provide support for single-unit or multi-unit restorations. When a one-stage surgical approach is applied, the S.I.N. Dental Implant System is intended for immediate loading when good primary stability is achieved and with appropriate occlusal loading. Implants with lengths less than 7 mm are intended for delayed loading only.

Device Story

S.I.N. Dental Implant System comprises threaded, cylindrical root-form implants (Unitite, Unitite Compact, Strong SW CM) and associated abutments. Implants are surgically placed in maxillary or mandibular bone by dental clinicians to support single or multi-unit restorations. System utilizes Morse taper connections; components are fabricated from commercially pure titanium, titanium alloy, cobalt-chromium, or polycarbonate. Surface treatments include acid-etching and hydroxyapatite (HA) coating. Device provides structural anchorage for prosthetic restorations (crowns, bridges, overdentures). Clinical benefit includes restoration of chewing function and dental aesthetics. No software or automated algorithms involved.

Clinical Evidence

No clinical data were included in this submission. Substantial equivalence is supported by non-clinical bench testing, including biocompatibility (ISO 10993 series), sterilization validation (ISO 11137, ISO 17665), shelf-life testing (ASTM F1980, F1929, F88), and surface area/insertion performance analysis.

Technological Characteristics

Threaded, cylindrical root-form dental implants and abutments. Materials: CPTi Grade 4, Ti-6Al-4V, CoCr, polycarbonate. Surface: Acid-etched and HA-coated. Connection: Morse taper. Dimensions: Diameters 2.9-6.0 mm, lengths 5-15 mm. Sterilization: Radiation (ISO 11137) and steam (ISO 17665). No software or electronic components.

Indications for Use

Indicated for patients requiring single or multi-unit dental restorations in the maxillary or mandibular arch. Suitable for immediate loading when primary stability and appropriate occlusal loading are achieved; implants <7 mm length restricted to delayed loading.

Regulatory Classification

Identification

An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore a patient's chewing function.

Special Controls

*Classification.* (1) Class II (special controls). The device is classified as class II if it is a root-form endosseous dental implant. The root-form endosseous dental implant is characterized by four geometrically distinct types: Basket, screw, solid cylinder, and hollow cylinder. The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)(2) *Classification.* Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use; (ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads; (iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system; (iv) The device must be demonstrated to be biocompatible; (v) Sterility testing must demonstrate the sterility of the device; (vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment; (vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians; (viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and (ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.

Dear Linda K. Schulz:

This letter corrects our substantially equivalent letter of December 1, 2017.

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food. Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

{7}------------------------------------------------

The subject device and predicate devices are substantially equivalent in intended use. Minor differences in language in the Indications for Use Statement between the subject device and the predicate devices do not change the intended use of implant placement and function. All are implant systems placed in the maxilla or mandible for single or multi-unit restorations with possible immediate loading for implants shorter than 7 mm is substantially equivalent to the statement in K120414 limiting immediate loading to implants 8 mm or greater.

Indications for Use Statements of the above predicates, K101225, K120414, and K081653 include an indication for immediate loading. The phrase, "Restorations supported by two or more Sistema de Implante Nacional implants may be loaded immediately after implant placement if primary implant stability has been achieved" in the primary predicate submission, K051859, has been replaced with the phrase, "S.I.N. Dental Implant System is intended for immediate loading when good primary stability is achieved and with appropriate occlusal loading" as seen for the reference predicate K101225. The phrase, crowns, bridges and overdentures has been replaced with the equivalent statement, "single-unit or multi-unit restorations." Minor changes in language to the Indications for Use Statement do not affect the safety, efficacy or substantial equivalence of the subject device.

Subject device implants are substantially equivalent to K051859 implants in body, connection design, material and acid-etched surface. The subject device implant HA surface is substantially equivalent to the K101225 surface treatment. The short implant is substantially equivalent to K092035 in size, surface area and function. Subject device abutments are substantially equivalent to K051859 and K120414 abutments in material, design and function. Subject device multi-unit abutments are substantially equivalent to K072570 abutments in material, design and function.

#### CONCLUSION

The subject device and the predicate devices have the same intended use, have similar technological characteristics, and are made of similar materials. The subject device and predicate devices encompass the same range of physical dimensions, including diameter, length and angle of the subject and predicate devices are packaged in similar materials and are to be sterilized using similar methods.

The data included in this submission demonstrate substantial equivalence to the predicate devices listed above.
