Intended Use
The Straumann CARES M-Series CAD/CAM System is indicated for the design and fabrication of single or multiple-unit implant-borne prosthetics for the restoration of partially or fully edentulous mandibles and maxillae. The system integrates multiple components of the digital dentistry workflow: scan files from Intra-Oral Scanners or Extra-Oral Scanners, CAD software, CAM software, restoration material blanks, milling machines and associated tooling and accessories. The system is used to design and fabricate CAD/CAM milled coping, crown and bridge restorations to be cemented onto Straumann® Variobase® Abutments, as well as milled abutments to be affixed to the endosseous dental implants of the Straumann® Dental Implant System using a basal screw.
Device Description
The Straumann CARES M-Series CAD/CAM System is intended for the design and fabrication of dental restorations by dental laboratories by means of a digital workflow. The workflow is unchanged from the primary predicate K171649. This premarket notification is introducing the Straumann Variobase Abutments for the BLX implant to abutment interface to the previously cleared workflow. The Straumann CARES M-Series CAD/CAM System employs optical impression files that document the topographical characteristics of teeth, traditional dental impressions, or stone models. The Straumann CARES Visual CAD software then allows the design of the desired restorations. The CAM software converts the digital restoration design into the tooling and tool path commands needed to fabricate the restoration. The CAM software also allows multiple restoration files to be combined (nested) in order to maximize the use of dental material blanks. The milling command file is encrypted prior to transfer to the M-Series mill; this encryption ensures that files generated using other CAD or CAM software cannot be used with the M-Series mill. The user will load the milling command file into the M-Series mill where it is decoded. The user loads the appropriate dental material blank and initiates the milling operation. This premarket notification includes restorations (copings, and bridges) manufactured from Zolid HT/Zolid SHT materials for cementation on Straumann Variobase Abutments for the BLX implant system. The BLX dental implant platforms include RB (Regular Base) and RB/WB (Regular Base/Wide Base). The combination of the coping, crown, or bridge and the Variobase Abutment component make up a two-piece abutment assembly, which is used in conjunction with endosseous dental implants for single or multiple tooth dental prostheses.
More Information

No
The document explicitly states "Mentions AI, DNN, or ML: Not Found" and describes a traditional CAD/CAM workflow without mentioning any AI/ML components.

No
The device is described as a CAD/CAM system for designing and fabricating dental restorations, which are prosthetic devices, not therapeutic.

No

Explanation: The device is described as a CAD/CAM system for designing and fabricating dental restorations (copings, crowns, and bridges). Its function is to create physical prosthetics, not to diagnose medical conditions or analyze patient data for medical insights.

No

The device is described as a "System" that integrates multiple components including CAD software, CAM software, restoration material blanks, milling machines, and associated tooling and accessories. While it includes software, it is not solely software and involves significant hardware components for fabrication.

Based on the provided text, the Straumann CARES M-Series CAD/CAM System is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use is for the design and fabrication of dental prosthetics (copings, crowns, bridges, and abutments) for restoring partially or fully edentulous mandibles and maxillae. This is a mechanical and restorative process, not a diagnostic one.
  • Device Description: The system uses digital workflows to create physical dental restorations from material blanks. It involves scanning, CAD design, CAM software, and milling machines. This describes a manufacturing process for medical devices, not a diagnostic test.
  • No mention of biological samples: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue). This device works with digital scans and material blanks.
  • No diagnostic claims: The text does not mention any claims about diagnosing a disease or condition.

The device is clearly intended for the fabrication of dental prosthetics, which are considered medical devices, but not IVD devices.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Comparative dynamic fatigue tests were conducted according to the FDA quidance document "Guidance for Industry and FDA Staff – Class II Special Controls Guidance Document: Rootform Endosseous Dental Implants and Endosseous Dental Abutments" and demonstrated the Straumann BLX Variobase® with Zolid SHT and Zolid HT crowns are equivalent to the primary predicate and reference devices.

The Milling System Validation was leveraged from K171649 to confirm the dimensions of the milled restoration were the same as the intended CAD design from CARES Visual. A Simulated Use validation was also leveraged from K171649 to confirm the scan, design, and production capability of the subject devices in CARES Visual. The subject devices were not considered a new worst case; therefore, the existing validations were referenced.

The subject device materials are identical to the predicate and reference device materials, therefore, no new issues regarding biocompatibility were raised.

The sterilization process for the Straumann Variobase® as recommended in the labeling was validated according to applicable recommendations in the FDA guidance document "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling, issued on March 17, 2015".

Device Description

The Straumann CARES M-Series CAD/CAM System is intended for the design and fabrication of dental restorations by dental laboratories by means of a digital workflow. The workflow is unchanged from the primary predicate K171649. This premarket notification is introducing the Straumann Variobase Abutments for the BLX implant to abutment interface to the previously cleared workflow.

The Straumann CARES M-Series CAD/CAM System employs optical impression files that document the topographical characteristics of teeth, traditional dental impressions, or stone models. The Straumann CARES Visual CAD software then allows the design of the desired restorations. The CAM software converts the digital restoration design into the tooling and tool path commands needed to fabricate the restoration. The CAM software also allows multiple restoration files to be combined (nested) in order to maximize the use of dental material blanks. The milling command file is encrypted prior to transfer to the M-Series mill; this encryption ensures that files generated using other CAD or CAM software cannot be used with the M-Series mill. The user will load the milling command file into the M-Series mill where it is decoded. The user loads the appropriate dental material blank and initiates the milling operation.

This premarket notification includes restorations (copings, and bridges) manufactured from Zolid HT/Zolid SHT materials for cementation on Straumann Variobase Abutments for the BLX implant system. The BLX dental implant platforms include RB (Regular Base) and RB/WB (Regular Base/Wide Base). The combination of the coping, crown, or bridge and the Variobase Abutment component make up a two-piece abutment assembly, which is used in conjunction with endosseous dental implants for single or multiple tooth dental prostheses.

Straumann® CARES M-Series CAD/CAM System

510(k) Summary

The digital workflow using the Straumann CARES M-Series CAD/CAM System includes the use of the following products:

Dental Scanner(s)

The Straumann CARES M-Series CAD/CAM system can accept files generated using the following devices (note that these are not subject devices to this submission):

  • Dental Wings Intra-Oral Scanner, DWIO .
  • Dental Wings 3-Series & 7-Series desktop scanners (extra-oral) .
  • Straumann CARES CS2 scanner (extra-oral) .

The dental scanner takes optical impressions that document the topographical characteristics of teeth, traditional dental impressions, or stone models. This includes the location and orientation of dental implants or abutments when a Scanbody is employed during the scan.

CARES Visual CAD Software

The CARES Visual software is a dental CAD application that allows the user to digitally design dental restorations, based on information that was acquired by a dental scanner. As a result of the design process and the indication and material dependent dimensional limits, a threedimensional geometry is created that is linked to the selected restorative material/milling blank. The use of the Straumann manufacturer provided digital device models assures the accuracy of the interfaces between the designed restoration and the abutment or implant being restored.

CARES Visual CAM Module

The CAM interface module converts the three-dimensional geometry into milling machine control data. The CAM software uses the digital restoration geometry information and the material selection to define the tools to be used, the paths the tools are to follow to re-create the digital geometry in physical form and the speed and feed rates of the mill and the tooling. The CAM software also allows for multiple restoration files to fit within the geometry of a single dental material blank (a process referred to as nesting) in order to maximize the use of dental material blanks.

The completed CAM file is encrypted prior to being output for transfer to the milling machine. This encryption ensures that files generated using other CAD or CAM software cannot be used with the M-Series mill. This is a means of assuring that only the validated product configuration is used.

Straumann® CARES M-Series CAD/CAM System

510(k) Summary

Straumann M-Series Milling Machine

The milling machine receives the CAM file from the CAM software. The user will load the CAM file into the M-Series mill where it is decoded. The user mounts the appropriate dental material blank, tools and burs. For certain materials the user will also employ a cutting fluid that acts as a lubricant and coolant for the milling operation. Once the machine is fully configured, the user initiates the milling operation.

Sintering Furnace

  • Straumann Therm ●
    Some restoration materials are provided in a green (i.e. partially crystallized) state or are combined with a polymeric binder material. This is typically done to make the machining process easier and to increase tool life. These materials must undergo a sintering process affer milling in order to achieve their final form. This is carried out in a sintering furnace.

The milled geometries, in the materials that require sintering, are larger than the finished restoration to account for the shrinkage that will occur during sintering. This scaling is included in the CAD software as a material specific parameter. The CAD software will scale the digital restoration design using this parameter prior to transfer of the data to the CAM software in order to assure that the final, sintered restoration accurately reflects the digital design.

Restoration Material Milling Blanks

A selection of milling blanks is available for use with the Straumann CARES M-Series CAD/CAM system. The materials and their design control limits are identified in Table 1.

| Material Name | Material | Minimum Post
Height (mm) | Maximum

Technological Characteristics

The technological characteristics of the subject devices are compared to the primary predicate device, Straumann CARES M-Series CAD/CAM System, and the reference devices in Table 2. The main technological difference is the implant to abutment interface of the Variobase Abutments. The BLX Variobase Abutments were cleared previously for centralized manufacturing at a Straumann Validated Milling Center with different restoration materials in K190040 and K190082. The in-lab workflow and the restoration materials (Zolid HT and Zolid SHT) are identical to the primary predicate.

K190662 is not included in Table 2 and is referenced for the MRI compatibility only.

Performance Testing

Comparative dynamic fatigue tests were conducted according to the FDA quidance document "Guidance for Industry and FDA Staff – Class II Special Controls Guidance Document: Rootform Endosseous Dental Implants and Endosseous Dental Abutments" and demonstrated the Straumann BLX Variobase® with Zolid SHT and Zolid HT crowns are equivalent to the primary predicate and reference devices.

The Milling System Validation was leveraged from K171649 to confirm the dimensions of the milled restoration were the same as the intended CAD design from CARES Visual. A Simulated Use validation was also leveraged from K171649 to confirm the scan, design, and production capability of the subject devices in CARES Visual. The subject devices were not considered a new worst case; therefore, the existing validations were referenced.

The subject device materials are identical to the predicate and reference device materials, therefore, no new issues regarding biocompatibility were raised.

The sterilization process for the Straumann Variobase® as recommended in the labeling was validated according to applicable recommendations in the FDA guidance document "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling, issued on March 17, 2015".

Conclusion

The documentation submitted in this premarket notification demonstrates the Straumann BLX Variobase® Abutments restored with Zolid HT and Zolid SHT restorations manufactured via the Straumann CARES M-Series CAD/CAM System workflow are substantially equivalent to the primary predicate and reference devices.
