Intended Use

Dentis I-FIX Abutment is intended for use as an aid in prosthetic rehabilitation.

Device Story

Dentis I-FIX Abutment system comprises I-FIX Angled Type Fixture Healing Abutment, I-FIX Angled Type Fixture Healing Abutment Screw, and I-FIX Abutment Screw. Device functions as prosthetic rehabilitation aid; healing abutments protect fixture inner holes and adjust height during healing; abutment screws connect abutments to fixtures. Used in dental clinics by dentists/specialists. Healing abutment components provided sterile; abutment screws provided non-sterile for end-user sterilization. Output is physical support for dental prosthetics, facilitating restoration of masticatory function. Benefits include protection of implant site during healing and secure attachment of prosthetic components.

Clinical Evidence

No clinical data. Substantial equivalence established via bench testing, including sterilization validation (ISO 11137, ISO 17665), shelf-life testing (ASTM F1980), and biocompatibility assessment (ISO 10993-1). MR environment safety evaluated via scientific rationale and literature review.

Technological Characteristics

Materials: Pure Titanium Grade 4 (ASTM F67) for healing abutment body; Ti-6Al-4V ELI (ASTM F136) for screws. Dimensions: 4.03mm diameter for healing abutment; 2.15mm diameter for screws. Sterilization: Gamma radiation for healing abutment set; end-user sterilization for abutment screw. Connectivity: None (mechanical).

Indications for Use

Indicated for use as an aid in prosthetic rehabilitation in patients requiring dental implant abutments.

Dear April Lee:

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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.

| Indications for Use | Dentis I-FIX Abutment is intended for use as an aid in prosthetic rehabilitation. | MegaGen Prosthetics are intended for use as an aid in prosthetic rehabilitation. | Dentis Dental Implant System is indicated for use in partially or fully edentulous mandibles and maxillae, in support of single or multiple unit restorations including cemented retained, screw retained, or overdenture restorations. Dentis Dental Implant System serves as temporary support for provisional prosthetic device during the healing phase of permanent endosseous dental implants. This is an implant abutment support prosthesis such as the artificial teeth used temporarily for the restoration of masticatory function of patients. | | |
| Sterilization | Gamma sterile | Gamma sterile | Gamma sterile | | |
| Comparison | When comparing the subject device to the primary predicate, the indication for use, use with screw, Male Screw X Pitch, function, and coating are the same. The difference between two devices are material and dimensions. To support the difference of material, K171027 was added. The dimensions of subject device are slightly smaller than the identified predicate devices; however, this difference is not an important factor to device performance. Therefore, subject device and predicate device are substantially equivalent. | | | | |

# Non-Clinical Test Data

Below tests were performed for predicate devices and leveraged for the subject device:

- Sterilization validation test on healing abutment made of Titanium Gr4 according to ISO . 11137-1,2,3 referenced in K210134
- Sterilization validation test on healing abutment made of Ti-6A1-4A1 ELI according to ISO ● 11137-1,2,3
- End User Sterilization Validation Test Report on Abutments according to ANSI/AAMI ST79, ● ISO 17665-1,-2, ISO 11737-1,-2, and ISO 11138-1 referenced in K111364
- Shelf Life Test on Healing Abutment according to ASTM F1980 referenced in K171027
- Biocompatibility testing according to ISO 10993-1:2009 for Pure Titanium Grade 4 or Ti-6Al-● 4V ELI referenced in K210134 and K16124

The results of the above tests have met the criteria of the standards and demonstrated the substantial equivalence with the predicate device.

Non-clinical test data was conducted in accordance with FDA Guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments". Clinical testing was not necessary to establish substantial equivalency of the device.

# MR Environment Condition

Non-clinical worst-case MRI review was performed to evaluate the metallic Dentis I-FIX Abutment 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 bodied, dental abutments, and fixation screws) and material composition. Rationale addressed parameters per the FDA Guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment," including magnetically induced displacement force and torque.

# Conclusion

Dentis I-FIX Abutment constitutes a substantially equivalent medical device, meeting all the declared requirements of its intended use. This system has the same intended use and fundamental scientific technology as its predicate devices. Therefore, Dentis I-FIX Abutment and its predicates are substantially equivalent.
