510(k) Summary
### 5.3 Device Description
The subject devices comprise the metallic endosseous dental implant abutments and metallic prosthetic superstructures cleared to market in the United States as of December 15, 2017 under K170838, K150203, and K142167 by Medentika GmbH as part of the Medentika Multi-Platform System.
Medentika Multi-Platform System is an abutment system including eleven abutment designs compatible with twelve currently marketed implant systems. The abutment designs include abutments for single-tooth and multiple-tooth restoration for supporting cement-retained, screw-retained or overdenture prostheses. Platform diameters range from 3.3 mm to 7.0 mm. Corresponding implant diameters range from 3.25 mm to 7.0 mm. Angled abutment designs for connections with anti-rotational features are available in two orientations, Type 1 and Type 2. Type 1 is for abutments with the cone angle oriented toward the flat of the anti-rotational feature and Type 2 is for abutments with the cone angle oriented toward the corner or lobe of the anti-rotational feature. The maximum angle for any abutment within the eleven systems is 21°.
The TiBases are titanium bases to be used as the lower part of two-piece abutments. The upper part of the two-piece abutment is a CAD/CAM designed and manufactured restoration. The TiBases are provided in several models and dimensions, according to the compatible implant systems declared in the Indications for Use statement.
The assessment of these devices in the MR environment has not resulted in any changes to the devices themselves. The proposed labeling change provides the parameters under which a patient having a restoration constructed using the devices of the Medentika Multi-Platform System can safely undergo an MRI scan.
The stock endossoues dental implant abutments are fabricated from titanium-aluminumvanadium (TAV) alloy and noble metal alloys. The CADCAM abutments are fabricated from commercially pure titanium. The materials for the TiBase copings and/or crowns include zerion and IPS e.max CAD.

### 5.6 Performance Data
The testing presented in this submission is consistent with the FDA Guidance entitled Establishing Safety and Compatibility of Passive Implants in the Magnetic Resonance (MR) Environment dated August, 2014 and the FDA Guidance document entitled Assessment of Radiofrequency-Induced Heating in the Magnetic Resonance (MR) Environment for Multi-Configuration Passive Medical Devices dated June 29, 2015. For the evaluation of displacement force, testing was conducted per the deflection angle test per ASTM F2052-15, Standard test method for measurement of magnetically induced displacement force on passive implants in the magnetic resonance environment.
For the evaluation of torsional force, testing was conducted per the procedure described by Shellock, et al. This method has been shown to be acceptable for the evaluation of torque for a metallic implant or device. According to ASTM F2213-06 (2011), Standard Test Method for Measurement of Magnetically Induced Torque on Passive Implants in the Magnetic Resonance Environment, such alternative methods are acceptable.
For the evaluation of RF-induced heating, testing was conducted per recommendations in ASTM F2182-11a.

510(k) Summary
Image /page/10/Picture/3 description: The image shows a black triangle with the letters "MR" in bold black font inside of it. Below the triangle, the words "MR Conditional" are written in a smaller, black font. The triangle is a simple, equilateral shape, and the text is centered below it.
Non-clinical testing and MRI simulations were performed to evaluate the dental implant abutment system offered by Medentika GmbH. Non-clinical testing demonstrates that these products are MR Conditional. A patient with an implant abutment from the Medentika Multi-Platform System can be scanned safely in an MR system under the following conditions:
- . Static magnetic field of 1.5 Tesla and 3 Tesla, only
- . Maximum spatial gradient magnetic field of 4,000 gauss/cm (40 T/m)
- Maximum MR system reported whole body averaged specific absorption rate . (SAR) of 2 W/kg and head average SAR of 3.2 W/kg, for 15 minutes of scanning (i.e., per pulse sequence) in the Normal Operating Mode
Under the scan conditions defined, the implant abutments from the Medentika Multi-Platform System are expected to produce a maximum temperature rise of 4.9℃ after 15-minutes of continuous scanning (i.e., per pulse sequence).
In non-clinical testing, the image artifact caused by the implant abutments from the Medentika Multi-Platform System extend approximately 10 mm from this device when imaged with a gradient echo pulse sequence and a 3 Tesla MR system
