No
The description focuses on the material, design process (CAD/CAM software), and manufacturing of a dental bridge. There is no mention of AI or ML in the intended use, device description, or performance studies.
No.
This device is described as a dental implant bridge used to restore chewing function, which is a restorative rather than therapeutic purpose according to the provided information.
No
The device is described as a "patient-specific, dental implant supported, screw-retained dental implant bridge" intended to "restore chewing function". Its purpose is restorative, not diagnostic.
No
The device description clearly states it is a physical dental implant bridge made from yttria-stabilized tetragonal zirconia, which is a hardware component. While it is designed using software, the device itself is not software-only.
Based on the provided information, the NobelProcera® Zirconia Implant Bridge is not an IVD (In Vitro Diagnostic) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body. The intended use and device description clearly state that this device is a dental implant supported bridge used to restore chewing function in patients. It is a physical prosthesis placed in the mouth, not a tool for analyzing biological samples.
- The device description focuses on the physical characteristics, design, manufacturing process, and connection to dental implants. There is no mention of analyzing blood, tissue, or any other bodily fluid or substance.
- The performance studies described are non-clinical fatigue testing of the assembled implant/abutment system. This is mechanical testing, not diagnostic testing of biological samples.
Therefore, the NobelProcera® Zirconia Implant Bridge falls under the category of a medical device, specifically a dental prosthesis, rather than an in vitro diagnostic device.
N/A
Intended Use / Indications for Use
The NobelProcera® Zirconia Implant Bridge are indicated for use as a bridge anatomically shaped and/or framework in the treatment of partially or totally edentulous jaws for the purpose of restoring chewing function.

Device Description
The NobelProcera Zirconia Implant Bridge (Dental Bridge) is a patient-specific, dental implant supported, screw-retained dental implant bridge which is connected to compatible Nobel Biocare root-form endosseous dental implants (Dental Implants) or Multi-unit Abutments and is intended to restore chewing function in partially and fully edentulous patients. The Dental Bridge is available as either a Framework requiring veneering in a dental lab or as a Full Contour design requiring minimum laboratory processing.
The Dental Bridge is made from yttria-stabilized tetragonal zirconia. It is designed in a dental laboratory, hospital or dental practice by scanning, designing and ordering the restoration using dental CAD/CAM software and approved dental scanner. The finished design is sent to Nobel Biocare manufacturing facility for industrial production. After production, the Dental Bridge is sent to the laboratory for finishing.
The Dental Bridge is available for use with Nobel Biocare's Dental Implants having Internal Conical Connection (CC), External Hex Connection, Internal Tri-Channel Connection and Nobel Biocare's Multi-unit Abutment connections. One Dental Bridge can feature connections to 2 up to 10 Dental Implants.
All Dental Bridges are provided with the required Clinical and/or Prosthetic Screw: The Clinical Screw connects the Dental Bridge with the Dental Implant. The Prosthetic Screw connects the Dental Bridge with a Multi-unit Abutment.
Dental Bridge connections on the Internal Conical Connection Dental Implant require use of Clinical Metal Adapters. Clinical Metal Adapters are provided with the Dental Bridge. No adapter is needed for the External Hex, Internal Tri-Channel, or Multi-unit Abutment connections.
Clinical and Prosthetic Screws are placed from the occlusal side of the restoration. To facilitate access to the connection of the restoration to the implant/abutment a screw channel must be designed into the restoration. The Dental Bridge feature an Angulated Screw Channel (ASC) when connected to a Dental Implant with Internal Conical Connection and has an ASC feature to connect to Multi-unit Abutments. NobelProcera Zirconia Implant Bridges ASC's angulation can be defined by the customer in an angulation (to the implant's or Multi-unit Abutment's axis) between 0° and 25°. The ASC allows access through a screw channel which is not in line with the implant.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
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". This testing involved examining finished assembled implant/abutment systems of the worst-case scenario through fatigue testing. The comparative testing was performed using similar test constructs with the identical testing protocols with the reference device K161416. The revised extension length (16mm, compared to predicate's 10mm) is supported by the fatigue performance testing provided in the premarket notification, demonstrating that the difference does not raise different questions of safety and effectiveness.
