Indications for Use
INOSS System is indicated for surgical placement in the upper and lower jaw arches, to provide a root form means for single-units' prosthetic attachment to restore a patient's chewing function. INOSS System can be placed with a conventional two stage surgical process with an option for transmucosal healing or they can be placed in a single stage surgical process for immediate loading when good primary stability is achieved with appropriate occlusal loading.
Device Story
INOSS System comprises endosseous dental implants (fixtures), healing abutments, cover screws, stock abutments, and abutment screws. Fixtures are unalloyed titanium (Grade 4, ASTM F67) with sandblasted acid-etched (SAT) surfaces; designed for surgical placement in jaw bone to support single-unit dental prostheses (crowns, bridges, dentures). System interfaces with bone via tapered body and self-tapping threads. Clinicians perform surgery in dental clinics; fixtures placed via one-stage or two-stage methods. Output is a stable root-form foundation for prosthetic attachment. Benefits include restoration of masticatory function. Device relies on mechanical osseointegration; no software or AI components.

### Indications for Use
INOSS System is indicated for surgical placement in the upper and lower jaw arches, to provide a root form means for single-units' prosthetic attachment to restore a patient's chewing function. INOSS System can be placed with a conventional two stage surgical process with an option for transmucosal healing or they can be placed in a single stage surgical process for immediate loading when good primary stability is achieved with appropriate occlusal loading.
### Substantial Equivalence
The subject device is substantially equivalent in indications and design principles to the predicate device and the reference device listed above. Provided at the end of this summary is a table comparing the Indications for Use Statements and the technological characteristics of the subject device, the predicate device, and the reference device.
The Indications for Use of the subject and predicate devices are substantially equivalent to that of predicate device(K170608). However, the subject device includes only an engaging connection and does not provide a non-engaging connection. Therefore, its Indications for Use are limited to "a root form means for single-units' prosthetic attachment to restore a patient's chewing function."
In contrast, the predicate device provides both engaging and non-engaging connections, and its Indications for Use are described as "a root form means for single or multiple units' prosthetic attachment to restore a patient's chewing function."
There is also a slight difference in the Trade Names referenced (Subject device : INOSS System , Predicate device : UF(II) Implant System).
The differences in the indications for use between the subject and predicate devices do not substantively alter their intended use and therefore do not impact the Substantial Equivalence determination.
The prosthetic interface connection, material, surface treatment and sterilization of INOSS Fixture are substantially equivalent to that of the predicate device(K170608) except for the wording regarding the name of surface treatment such as SLA. The differences in the specific wording do not change the surface treatment.
All size range of the INOSS Fixture as subject device is substantially equivalent to that of the predicate device(K170608), reference device(K182194), reference device(K212533), and reference device(K111889). Ø3.9, Ø4.3 with all length of INOSS Fixture as subject device is substantially equivalent to that of reference device(K163194). Ø4.9, Ø5.4 with all length of INOSS Fixture as subject device is substantially equivalent to that of predicate device(K170608). Ø6.2 with length 8.0mm, 10.0mm, 11.5mm and 13.0mm of the INOSS Fixture as subject device is substantially equivalent to that of the reference device(K182194). Ø6.2 with length 16.0mm is substantially equivalent to that of the reference device(K212533). Implant body feature except the texture with grooves is same as predicate device (K170608). The texture with grooves is same with Reference device (C).
The INOSS Abutment, as the subject device, is substantially equivalent to the predicate device (K170608), reference device (K210826), reference device (K182081), reference device (K222636), reference device (K172100), and reference device (K161689) with respect to raw materials, dimensions, surface treatment, and sterilization.
