The Straumann CARES P-Series CAD/CAM System employs optical impression files that document the topoqraphical characteristics of teeth, traditional dental impressions, or stone models. The Straumann CARES Visual CAD software then allows the desired restorations. The CAM software converts the digital restoration design into the sequential slice geometries needed to 3D print a restoration or multiple restorations in a print job. The printing file is transferred to the Straumann P-Series 3D printer; where it is decoded into the defined printing slices and the user initiates the printing operation. The Straumann P-Series 3D printer will then print the designed restoration using the Straumann P Pro Crown & Bridge resin. The user of a Straumann CARES P-Series CAD/CAM System can design dental implant borne restorations using Straumann Variobases as the connecting interface to the implant. By this, the user will create two-piece abutments with the 3D printed part being the upper part of the implant borne restoration. {5}------------------------------------------------ ### Straumann CARES P-Series CAD/CAM System #### 510(k) Summary The Straumann Variobases that can be restored via the Straumann CARES P-Series CAD/CAM System include the following models and platforms: - . RC (Reqular CrossFit®) - . NC (Narrow CrossFit®) - . RN (Regular Neck) - . WN (Wide Neck) - RB (Regular Base) . - RB/WB (Regular Base/Wide Base) . The Straumann® Variobases are pre-manufactured (stock) items, sometimes referred to as "Tibases", made from a titanium-aluminum-niobium (Ti6Al7Nb, TAN) allov. They are the bottom half of the two-piece abutment. The 3D printed polymeric portion of the dental restoration will have a connecting interface to the coronal aspect of the Variobase, so that it can be cemented to that connecting interface. The 3D printed items feature a screw channel hole so that the cemented two-piece abutment can be affixed via a basal screw to the dental implant. The dental restoration is the top half of the twopiece abutment. | Type | Implant-borne | Image | |-------------|-------------------------------------------------|------------------------------------------------| | Single unit | Using previously cleared Variobase Abutments | Image: dental implant Image: dental implant | | Multi-unit | Using previously cleared Variobase Abutments | Image: dental implant in mouth | The different types of restorations are described in Table 1. Table 1 – Types of restorations {6}------------------------------------------------ ### Straumann CARES P-Series CAD/CAM System #### 510(k) Summary The digital workflow using the Straumann CARES P-Series CAD/CAM System includes the use of the following products: #### Dental Scanner(s) The Straumann CARES P-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) The dental scanner takes optical impressions that record 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 the Straumann P pro Crown & Bridge design dimension limits, a three-dimensional geometry is created. The use of Straumann provided digital device models (interface library) assures the accuracy of the interfaces between the designed restoration and the Variobase® being restored. #### CAM Module The CAM interface module converts the digital three-dimensional restoration geometry into the layer geometries for the 3D printer. #### Straumann P-Series 3D printer The 3D printer receives the CAM file from the CAM software. The user loads the CAM file into the Straumann P-Series 3D printer and initiates the 3D printing process. #### Centrifuge A centrifuging process is carried out to remove non polymerized resin from the surface of the printed dental restoration, without the use of a solvent, before the curing process. {7}------------------------------------------------ ### Straumann CARES P-Series CAD/CAM System 510(k) Summary #### Post Curing After the centrifyge process, the printed restorations need to undergo a final light-induced polymerization process, so that the device achieves its tested physical and mechanical characteristics. #### 3D printing resin The Straumann P pro Crown & Bridge resin is the raw material used to create the 3D printed restorations. The material is available in three different color shades, A1, A2 and A3. The Straumann P pro Crown & Bridge material has received 510(k) clearance through K200039, as a temporary restoration for crowns and bridges (CFR 872.3770, Product Code EBG).

The subject device features an additive 3D printing CAD/CAM procedure while the primary predicate device features a subtractive milling CAD/CAM process. The proposed device uses a 510(k) cleared acrylic resin, Straumann P pro Crown & Bridge (K200039) for temporary use, while the primary predicate uses zirconia milling disks or glass ceramic blocks for permanent use. The intended use for both, production of a crown or bridge on Ti-bases, is substantially equivalent as an endosseous dental implant abutment (CFR 872.3630, Product Code NHA). Design Specifications – There are differences in the minimum abutment post height and minimum wall thickness between the subject and predicate devices. Fatique testing of the subject and predicate devices has assured that the subject and predicate device values for these are sufficient for their intended use. The maximum number of units and maximum number of pontics is specified by the material manufacturer and depends on the material. The values used for the subject and predicate devices correspond to the values specified by the respective material manufacturer. The Design Specifications are thus substantially equivalent. #### Performance Testing Dynamic fatigue and static strength tests were conducted according to the FDA guidance document "Guidance for Industry and FDA Staff – Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments" and demonstrated that the Straumann Variobases restored with P pro Crown & Bridge constructs are equivalent to the primary predicate and reference devices. The subject device materials are identical to reference device materials. Biocompatibility tests of the P pro Crown & Bridge material in K200039 (including cytotoxicity, sensitization, irritation) were passed successfully. Therefore, no new issues regarding biocompatibility were raised. The sterilization process for the Straumann Variobase® 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". Software verification and validation testing was provided for the subject abutment design library to demonstrate effective use with the Straumann CARES Visual CAD software. Software {12}------------------------------------------------ ## Straumann CARES P-Series CAD/CAM System #### 510(k) Summary verification and validation testing was conducted to demonstrate that the restrictions prevent design of the top half component of the two-piece abutment outside of the allowable design limitations, including screenshots under user verification testing. In addition, the encrypted abutment design library was validated to demonstrate that the established design limitations and specifications are locked and cannot be modified within the abutment design library. Non-clinical testing and MRI simulations were performed to evaluate the dental implant system offered by Institut Straumann AG. Non-clinical testing demonstrates that these products are MR Conditional. Verification of the 3D printer system showed that the design input matched the output, that the process is r…
