The summary describes a dental abutment system and its components, focusing on materials, manufacturing processes (CAD/CAM and milling), and performance testing (biocompatibility, sterilization, MRI compatibility). There is no mention of AI or ML in the intended use, device description, or performance studies.
No.
The device is a component used with dental implants to support prosthetic restorations, not a therapeutic device designed for treating or curing a disease or condition.
No
Explanation: The device, Ti-Base & Master Fix, is described as a two-piece abutment used in conjunction with dental implants to provide support for prosthetic restorations. Its function is structural and restorative, not diagnostic.
No
The device description clearly outlines physical components (Ti-Base, Master Fix, Abutment Screw) made of materials like titanium and zirconia, which are manufactured and provided as non-sterilized physical devices. The software aspect is limited to the digital design of the superstructure, which is then sent for physical milling.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to provide support for prosthetic restorations in conjunction with dental implants. This is a structural and mechanical function within the body, not a diagnostic test performed on samples taken from the body.
- Device Description: The device is described as a two-piece abutment consisting of a titanium base and a zirconia superstructure. This is a physical component used in dental procedures.
- Lack of IVD Characteristics: There is no mention of the device being used to test samples (blood, urine, tissue, etc.) or to provide diagnostic information about a patient's health status. The focus is entirely on its role in supporting dental prosthetics.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.
N/A
Intended Use / Indications for Use

Device Description
The Ti-Base & Master Fix consists of a two-piece abutment, where the titanium base is a premanufactured abutment that will be used to support a CAD/CAM designed superstructure (the second part of the two-piece abutment) that compose the final abutment.
Device Components:
- Abutment
- Ti-Base
- Master Fix
- Abutment Screw
The Ti-Base and Master Fix are provided non-sterilized. Ti-Base is enclosed with Abutment Screw in a packing. Master Fix is enclosed with Master Fix Screw in a packing. These devices are intended for single use only. All digitally designed custom abutments for use with Ti-Base or Master Fix are to be sent to ARUM DENTISTRY validated milling center for manufacture. All superstructures are to be manufactured from zirconia (cleared K190112). Digitally designed CAD/CAM abutments must have a 0.5 mm minimum gingival height dimension.
The Titanium Base abutment is composed of two-piece abutment that is a titanium base at the bottom and a zirconia superstructure (CAD/CAM patient specific superstructure) at the top. The zirconia superstructure is straight only and is not to be designed to provide an angle or divergence correction.
For the Ti-Base the design parameters for the CAD/CAM zirconia superstructure are:
Minimum wall thickness - 0.5 mm;
Minimum post height* for single-unit restorations - 4.5 mm;
Maximum gingival height - 5.0 mm;
Minimum gingival height - 0.5 mm;
Angulation - 0°
and All zirconia superstructures are for straight abutments only.
*Post Height is measured above the gingival height of the final patient-matched design
For the Master Fix, the design parameters for the CAD/CAM zirconia superstructure are:
Minimum wall thickness - 0.5 mm;
Minimum post height* for single-unit restorations - 4.0 mm;
Maximum gingival height - 5.0 mm:
Minimum gingival height - 0.5 mm;
Angulation - 0°
and All zirconia superstructures are for straight abutments only.
*Post Height is measured above the gingival height of the final patient-matched design
The Ti-Base and Master Fix is compatible with the NB 1 SA Implant System (K213506) and NB Implant System (K230725) from ARUM DENTISTRY Co., Ltd.
The titanium bases are used as part of a two-piece abutment, where the base is premanufactured from titanium alloy (Ti-6Al-4V Eli) and the top half is a CAD/CAM zirconia superstructure, milled at a validated milling center. These pieces are cemented together to form the final abutment.
Pre-Manufactured titanium components of Abutment Screws are fabricated from Ti-6Al-4V Eli (Conforming to ASTM F136).

Discussion | 2. Differences
The minor differences with the primary predicated K191986 are slightly different dimension and insignificant
shapes. However, the subject diameters are in the range of diameters of primary predicate and this dimensional
difference doesn't affect device safety and effectiveness. The shape is only for the manufacture's properties
such as design and compatible to their own dental implant design. These minor differences do not impact safety
and effectiveness because these differences are related to the compatible implant design and are mitigated by
the mechanical performing testing. |

| The Abutment Screw has same indication for use, principle of operation, functions, to secure a dental | ||
| abutment to a dental implant in the upper or lower jaw, and material to the predicate K213506. |
- Differences
The screw's design features a larger head to increase retention in screw-retained prostheses. The
extended head fills the abutment's empty space, enhancing stability and preventing screw fractures.
Additionally, the design facilitates easier access for the screw driver.
However, it does not affect device's fundamental functions and safety; therefore, it is substantial
equivalent. | |

Performance Data
Non-clinical data submitted to demonstrate substantial equivalence include: biocompatibility testing according to ISO 10993-5 and ISO 10993-12 and moist heat sterilization validation according to ISO 17665 -1 and ISO 17665-2.
No clinical data were included in this submission.
MR Environment Condition
Non-Clinical worst-case MRI review was performed to evaluated the NB Mini Implant System devices in the MRI environment using scientific rationale and published literature (e.g., Terry O. Woods, Jana Delfino, & Sunder Rajan. (2019). Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices. Journal of Testing and Evaluation 49.2, 783-795), based on the entire system including all variations (all compatible implant bodies, 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
The Subject device and the Primary predicate device have the same intended use, have the same technological characteristics, and are made of the same materials. The Subject device and the Primary predicate device encompass the same range of physical dimensions and are to be sterilized using the same methods. Although there is slightly difference design of the anti-rotation feature, this difference is the same purpose. This minor difference do not impact safety and effectiveness because this difference are related to increase the adhesion of cement to the prosthesis. The data included in this premarket notification demonstrate substantial equivalence to the primary predicate device listed above. Therefore, the subject device and primary predicate device are substantial equivalence.
