The description details a CAD/CAM process for designing and manufacturing dental bars based on patient scans. While this involves computer-aided design and manufacturing, there is no mention of AI or ML algorithms being used for design optimization, analysis, or any other function. The process appears to be based on standard digital design and manufacturing techniques.
Yes.
Explanation: The device is intended to support a prosthetic device to restore chewing function in patients, which directly addresses a health-related purpose by improving a physiological function.
No
Explanation: The device is a dental restorative device, specifically a milled bar, intended to support prosthetic devices in edentulous patients for restoring chewing function. It is not used for diagnosing medical conditions.
No
The device is a physical metallic dental restorative device (milled bar) that is manufactured using CAD/CAM software, but the software is a tool for creating the physical product, not the medical device itself.
Based on the provided information, the Panthera Dental Milled Bar is not an IVD (In Vitro Diagnostic) device.
Here's why:
- Intended Use: The intended use is to support a prosthetic device in a patient to restore chewing function. This is a direct therapeutic and restorative function within the patient's body, not a diagnostic test performed on a sample taken from the body.
- Device Description: The device is a metallic dental restorative device intended for attachment to dental implants. It is a physical component used in a surgical and restorative procedure.
- Lack of Diagnostic Function: There is no mention of the device being used to diagnose a disease, condition, or state of health. It does not analyze biological samples (blood, urine, tissue, etc.) to provide diagnostic information.
- Regulatory Classification: The description and testing performed (mechanical strength, biocompatibility, fatigue testing) are typical for a medical device used in a surgical or restorative context, not an IVD. The predicate devices are also dental restorative devices.
In summary, the Panthera Dental Milled Bar is a dental prosthetic component used for treatment and restoration of function, not for in vitro diagnostic testing.

Device Description
The Panthera Dental Milled Bar is a metallic dental restorative device which is intended for attaching by screw retention to dental implants to aid in the treatment of partial and totally edentulous patients for the purpose of restoring chewing function.
The Panthera Dental milled bars for which clearance is requested, are included in one of the following bar types, which have distinct design specifications.
The Type I bars are specific for removable overdenture and include:
- Panthera Dental Dolder Bar, Hader Bar, Milled Bar, REBourke Bar and ● Paris Bar.
The Type II bars are specific for fixed prostheses and include:
- . Panthera Dental Wrap-around Bar, Montreal Bar, Montreal Bar with metallic lingual, Pin Lingual Bar and Pin Wrap-Around Bar.
The Panthera Dental Milled Bar is designed to match an individual patient. Panthera Dental designs the bar from a three-dimensional optical and/or digital scanner system that scans the casting of a patient's impression: the model cast is prepared beforehand by the dental professional using standard dental techniques. The designed bar is then machined using a computer-aided design/ computer-aided manufacturing software system (CAD/CAM). The bar is milled from titanium (Ti-6AI-4V grade 5). CAD/CAM fabrication is only performed by Panthera Dental, within our manufacturing control and not by the dental laboratory.
The Panthera Dental Milled Bar is packaged as non-sterile, and delivered to a dental laboratory for completion. Once received at the laboratory, the Panthera Dental Milled Bar is matched to a denture for final placement.
The Panthera Dental Milled Bar provides retention and support for a removable or fixed denture made of standard laboratory dental materials such as resin composite.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-Clinical Testing:
- FMEA risk analysis
- Evaluation of the materials of construction and the design.
- Non-clinical testing includes assessment of the physical properties of the bars and its ability to achieve its intended use. The bars meet the same specifications as set for the predicate device.
- Sterilization validation: Validation of the sterility test used to test the sterility of the dental bars after the sterilization cycle, validation parameters based on USP (Sterility Tests). Sterility test demonstrated that the Panthera Dental bars were sterile once the cycle was completed. Performed in an FDA cleared sterilizer (# K111223), Amsco Chimeron Small Prevacuum Steam Sterilizer. Qualified according to Section 5.5.4 of ANSI/AAMI-ST8. Sterility assurance level of at least 10-6 using half-cycle analysis.
- Biocompatibility analysis: Cytotoxicity, extractable chemical analysis, toxicological risk assessment, and bacterial endotoxins testing performed with the Panthera Dental bars support substantial equivalence to the predicate, following the standards of ISO 10993-1, ISO 10993-5, ISO 10993-12, ANSI/AAMI ST72, and USP .
- Finite Element Analysis (FEA) was done on the dental bar.
- Fatigue Testing: Two (2) static and two (2) dynamic tests completed. First test on the bar itself (cantilever section of the bar) and the second on the bar cylinders. Performed in accordance with ISO 14801 standard and FDA guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments; guidance for industry and FDA." Results demonstrated that the Panthera Dental Milled Bar and its cylinders have sufficient mechanical strength for its intended clinical application.
- Reverse engineering analysis: Used to determine the critical parameters of the design of each interface connection including the tolerance limits between each components per size and type, for the Zimmer TSV system. Generated critical parameters and manufacturing tolerances for Zimmer TSV device interface connection. Verified proper seating of the cylinder on the implant and insertion/seating of the screw in the cylinder in final Panthera assemblies.
- Process capability study: Thirty (30) cylinders were manufactured and measured to determine the Cpk value of each of their critical dimensions. The milling process successfully passed the standards with a Cnk value higher than 1.0 for each critical dimension. Showed that even with a worst-case process mean shift of 1.5σ, the manufactured bar's cylinders from Panthera Dental's CAD/CAM milling process do not exceed the specification limits.
Clinical Testing:
- Human clinical study was not deemed necessary to support substantial equivalence.

Panthera Dental Inc. performed no clinical testing. However, a FMEA risk analysis, and evaluation of the materials of construction and the design were performed. The function of the bars requires that the prescribing dentist is cognizant of the potential for soreness, soft tissue soreness, and dentition complications by the bars. Management of these risks is achieved by advising the patient and dentist in the directions for use that early and repeated examination of the performance of the device, and its fit, must be performed in the dental office by the prescribing dentist. The precautions, storage directions and prescription preparation instructions are written to avoid potential problems from arising or persisting with the dentition or tissue, caused by the bars. The proprietary manufacturing of the Panthera Dental bar includes materials for the milling, the polishing and the cleaning that are biocompatible and from standard manufacturing in dental practices. This manufacturing process does not alter the chemical or physical properties of the Panthera Dental bar. No new risks are introduced with the new device that are not present in the predicate device.
Non-Clinical Testing
The non-clinical testing includes assessment of the physical properties of the bars and its ability to achieve its intended use. The bars meet the same specifications as set for the predicate device.
Sterilization
A sterilization validation was performed. The complete validation of the pre-vacuum steam sterilization cycle has been performed.
The first part of the validation consisted in the validation of the sterility test used to test the sterility of the dental bars after the sterilization cycle; validation parameters where based on USP (Sterility Tests). In the second part, the sterility test has demonstrated that the Panthera Dental bars were sterile once the above cycle was completed. The sterilization test was performed in an FDA cleared sterilizer (# K111223), Amsco Chimeron Small Prevacuum Steam Sterilizer. Based on the effectiveness statement of this sterilizer, the Prevac cycle was validated using full load instrument trays, described in 5.5.4.1 of ANSI/AAMI-ST8, and was qualified according to Section 5.5.4 of ANSI/AAMI-ST8. This cycle demonstrated a sterility assurance level of at least 10-6 using half-cycle analysis. The sterilization process is a typical steam autoclave sterilization process, it does not alter the chemical or physical properties of the Panthera Dental bar.

Biocompatibility
The biocompatibility analysis provided herein supports the substantial equivalence in the safety and effectiveness of the predicate device. The raw material used in the manufacturing of the Panthera Dental bar is the same as for the predicate device: Titanium Ti-6Al-4V. Both Panthera Dental bar and the predicate bar are categorized as external communicating devices that contact tissue/bone/dentin for more than 30 days. The cytotoxicity, the extractable chemical analysis, the toxicological risk assessment and the bacterial endotoxins testing performed with the Panthera Dental bars support substantial equivalence to the predicate, following the standards of ISO 10993-1, ISO 10993-5, ISO 10993-12, ANSI/AAMI ST72, and USP . Therefore we believe that the new device is as safe as the legally marketed device.
FEA
Finite Element Analysis (FEA) was done on the dental bar prior to starting any testing.
Fatigue Testing
Fatigue testing was performed on the Panthera Dental bar: two (2) static and two (2) dynamic tests were completed. The first test was performed on the bar itself (cantilever section of the bar) and the second one was performed on the bar cylinders. The testing was performed in accordance with the ISO 14801 standard (Dentistry - Implants-Dynamic fatigue test for endosseous dental implants) and the FDA guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments; guidance for industry and FDA." The results have demonstrated that the Panthera Dental Milled Bar as well as the cylinders constituting the bar, have sufficient mechanical strength for its intended clinical application.
Reverse engineering analysis
Panthera Dental has used the RE method to determine the critical parameters of the design of each interface connection including the tolerance limits between each components per size and type, for the Zimmer TSV system. This rigorous reverse engineering of all the components has generated the critical parameters as well as the manufacturing tolerances for Zimmer TSV device interface connection. With those in hand, it was possible to reproduce an exact copy of the Zimmer TSV cylinder's interface connection and to ensure a compatible fit between the proposed cylinder and their Zimmer TSV reverse engineered counterparts (OEM implant bodies, OEM abutments, and OEM fixation screws).
The RE of the three Zimmer components: OEM implant bodies, OEM abutments, and OEM fixation screws, gives the assurance that the RE values of the connection interfaces of our proposed device fall within the measured sizes of the counterpart Zimmer implants/ screws and confirms that the Panthera Dental assemblies will always be functional with no possible interference.

The company name is written in a stylized font, with the word "PANTHERA" in a larger font size than the word "DENTAL". The color of the company name is purple.
RE, the different gaps were verified in the final Panthera assemblies and confirms proper seating of the cylinder on the implant as well as the insertion and the seating of the screw in the cylinder.
Process capability study
In order to confirm the reliability of the manufacturing process of the Panthera Dental bars, a process capability test was performed. This test allows the determination of the capability index and therefore indicates the level at which the CAD/CAM manufacturing process is able to perform considering every inherent natural variation of each step of the whole manufacturing workflow. Thirty (30) cylinders were manufactured and measured to determine the Cpk value of each of their critical dimensions. The milling process successfully passed the standards with a Cnk value higher than 1.0 for each critical dimension. This test also showed that even with a worst-case process mean shift of 1.50, the manufactured bar's cylinders from Panthera Dental's CAD/CAM milling process do not exceed the specification limits. The process is therefore reliable for the manufacturing of the Panthera Dental Milled Bars.
Clinical Testing
Human clinical study was not deemed necessary to support substantial equivalence. The Panthera Dental Milled Bars do not: use designs dissimilar from the predicate device and other previously cleared devices under a 510(k); do not use new technologies different from legally marketed milled bars; and do not deviate from the indications for use identified in the predicate device: CAM StructSURE Precision Milled Bars.

Below the panther, the word "PANTHERA" is written in a bold, sans-serif font, with the word "DENTAL" in a smaller font size underneath it. The word "PANTHERA" and the line under it are purple.
Substantial Equivalence Conclusion
The new device, Panthera Dental Milled Bar, is considered to be substantially equivalent to the predicate based on the following: it has essentially the same indications for use and is indicated for the same user population; it uses biocompatible material for the manufacturing, as the predicate does; the manufacturing process does not alter the biocompatibility of the device; and it has equivalent technological characteristics to those of the predicate.
