Intended Use
The TDS (TECHWIN DENTAL SYSTEM) are prefabricated prosthetic components for direct connection to endosseous dental implants and are intended to be used as an aid in prosthetic rehabilitation. It is intended for use in edentulous and partially edentulous patients with established bone and completed growth period to support single unit prosthetic restorations in the mandible or maxilla. It is intended for one-stage and two-stage surgical procedures. This system is intended for delayed loading.
Device Description
The TDS (TECHWIN DENTAL SYSTEM), made of Ti-6A1-4V ELI alloy (ASTM F136), is intended for use in conjunction with the appliance in partially or fully edentulous mandibles and maxillae to support single-unit loading (i.e., crown). It consists of the Dual Abutment and Healing Abutment. The surface of the abutments is uncoated or partially or half coated with TiN using AIP (Arc Ion Plating). The implant-to-abutment interface remains uncoated. All abutments are supplied non-sterile and must be autoclaved by the end-user.
More Information

Not Found

No
The provided text describes a dental implant system made of specific materials and intended for prosthetic rehabilitation. There is no mention of AI, ML, image processing, or any software-driven analytical capabilities that would suggest the use of AI/ML. The performance studies focus on material properties, sterilization, and compatibility, not algorithmic performance.

No.
The device is described as prefabricated prosthetic components for direct connection to dental implants, intended to aid in prosthetic rehabilitation by supporting single-unit prosthetic restorations. Its purpose is structural support, not direct treatment of a disease or condition.

No

This device is described as prefabricated prosthetic components (abutments) for dental implants, used in prosthetic rehabilitation to support single unit prosthetic restorations. It is not intended for the purpose of diagnosis.

No

The device description explicitly states it is made of Ti-6A1-4V ELI alloy and consists of physical components (Dual Abutment and Healing Abutment). This indicates a hardware device, not software only.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use clearly states that the TDS are "prefabricated prosthetic components for direct connection to endosseous dental implants and are intended to be used as an aid in prosthetic rehabilitation." This describes a device used in vivo (within the body) for structural support and restoration, not a device used in vitro (outside the body) to examine specimens from the human body to provide information for diagnosis, monitoring, or treatment.
  • Device Description: The description details the physical components (abutments), material (Ti-6A1-4V ELI alloy), and surface treatments. This aligns with a medical device intended for implantation or connection to an implant, not a diagnostic test.
  • Lack of Diagnostic Elements: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting biomarkers, or providing diagnostic information.
  • Performance Studies: The performance studies focus on biocompatibility, surface characteristics, sterilization, MRI compatibility, and compatibility with implants – all relevant to an implantable or connected medical device, not an IVD.

In summary, the TDS is a dental prosthetic component, which falls under the category of a medical device, but not an In Vitro Diagnostic device.

| SE | The subject device has a similar intended use, material, and design as the predicate device,
with only minor differences in dimensions. While the subject device is indicated for single-
unit loading only, as opposed to single and multiple-unit loading for the predicate device,
this represents a more conservative approach that doesn't introduce additional risks. The
abutment gingival height range of the subject device falls within the range of the predicate
device, and the minor differences in diameter and post height are intended to meet
individual patient needs without compromising performance or safety. The 4.0 mm
minimum abutment post height of the subject device, compared to the 4.5 mm of the
predicate device, allows for greater flexibility to accommodate patient-specific anatomical
variations without affecting safety or effectiveness. Although the subject device uses Ti-6Al-
4V ELI titanium alloy instead of titanium grade 4 used in the predicate, both materials are
well-established in dental implant applications, with Ti-6AI-4V ELI offering improved
mechanical properties and biocompatibility. The connection interface remains the same
between the devices. These differences do not raise any new safety or effectiveness issues,
maintaining substantial equivalence between the subject and predicate devices. | | |

| SE | The subject device has a similar intended use, material, and design as the predicate device, with only minor differences in dimensions. The abutment post height and gingival height range of the subject device fall within the range of the predicate device. While there are minor differences in diameter, these variations are intended to meet individual patient needs and do not compromise performance or safety due to their minimal nature. The subject device uses Ti-6Al-4V ELI titanium alloy, whereas the predicate uses titanium grade 4. Both materials are well-established in dental implant applications, with Ti-6Al-4V ELI offering improved mechanical properties and biocompatibility. This material difference maintains substantial equivalence without raising new safety or efficacy concerns. Additionally, the subject device offers both non-coated and TiN-coated options for the Healing Abutment, while the predicate device uses only TiN coating. This flexibility in surface treatment allows for customization based on specific clinical needs without compromising the device's overall performance or biocompatibility. Furthermore, the connection interface remains the same between the devices. These minor variations do not introduce any new issues in performance or safety, thus maintaining substantial equivalence between the subject and predicate devices. | | |

IX. NONCLINICAL TEST

The following performance data was provided in support of the substantial equivalence determination.

Biocompatibility

Biocompatibility classification is based on the FDA Guidance Use of International Standard ISO 10993-1, "Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing within a Risk Management Process."

The subject devices are classified as an implant medical device, tissue/bone, long-term exposure (>30 days).

The subject devices have fulfilled all testing required by ISO 7405:2018, "Dentistry -Evaluation of biocompatibility of medical devices used in dentistry", ISO 10993-1:2018, "Biological evaluation of medical devices – Part 1: Evaluation and testing" and the FDA guidance document "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process". Cytotoxicity testing according to ISO 10993-5:2009 "Biological evaluation of medical devices - Part 5: Tests for in vitro cytotoxicity", irritation testing according to ISO 10993-10:2010 and ISO 10993-23:2021, and implantation testing according to ISO 10993-6:2016 was performed to demonstrate the subject device is substantially equivalent to the predicate device (K160536).

Surface treatment

Surface treatment analysis was conducted in-house for the TDS (TECHWIN DENTAL SYSTEM). This included chemical composition analysis, scanning electron microscopy analysis, surface roughness measurements, coating thickness and porosity evaluation, mean volume percent of voids calculation, and abrasion characteristics assessment.

The logo features the text "SMB Korea" in a sans-serif font, with a stylized swoosh graphic element underneath the letters "SMB". Below the main text, in a smaller font size, is the tagline "A Member of the Consulting Expert Group."

Sterilization

The non-sterile abutments used in the surgery must be sterilized by the end user, prior to use, as specified in the IFU. User moist heat sterilization validation for the subject non-sterile devices was conducted according to, ISO 17665-1:2006, "Sterilization of health care products - Moist heat - Part 1: Requirements for the development, validation and routine control of a sterilization process for medical devices", and ISO/TS 17665-2:2009, "Sterilization of health care products – Moist heat – Part 2: Guidance on the application of ISO 17665-1" and demonstrated a SAL of 10-6.

A non-clinical worst-case MRI review was performed to evaluate the subject device components in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry O., Jana G. Delfino, and Sunder Rajan. "Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices." Journal of Testing and Evaluation 49.2 (2019): 783-795), based on the entire system including all variations (all compatible implant bodies, abutments) and material composition. The rationale addressed parameters according to the FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment", including magnetically induced displacement force and torque.

Reverse engineering analysis

Reverse engineering was performed to ensure compatibility with third-party implants. This process involved precise measurements of implant-abutment interfaces, tolerances, and connection geometries. Reverse engineering of OEM implant bodies, OEM abutments, and OEM abutment screws was performed to ensure compatibility with third-party implants.

X. CLINICAL TESTS

This 510(k) does not include data from clinical tests.

XI. CONCLUSIONS

The above information supports that the TDS (TECHWIN DENTAL SYSTEM) is as safe and effective as the predicate device. Although there are minor design differences between the device under subject device and the predicate device, the review supports that these differences do not raise new questions of safety and effectiveness. Therefore, it is concluded that the TDS (TECHWIN DENTAL SYSTEM) is substantially equivalent to the predicate device.
