    Intended Use

    The Straumann CARES Visual/Nova Implant-borne CAD software are indicated for the design of two-piece or one-piece abutment components for 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 and CAD software. The system is used to design two-piece abutment CAD/CAM milled copings, crown and bridge restorations to be cemented onto Ti-bases, customized one-piece abutments and bridges/bars to be affixed to the endosseous dental implants using a basal screw. The use of the software requires the user to have the necessary training and domain knowledge in the practice of prosthetic design, as well as training in the use of the software.

    Device Description

    Straumann CARES Visual/Nova is a dental CAD software to create implant-borne restorations. The software employs optical impression files that represent the topographical characteristics of the patient's intraoral situation. The Straumann CARES Visual/Nova software then allows the desired restorations. All implant-borne restorations available in Straumann CARES Visual/Nova software require FDA review and 510(k) clearance. Design specifications ("design envelope"), selectable materials, mouth positions need to be described in these 510(k) submissions. Each restorative solution is defined in a secured design library that provides the CAD software with the design specifications and restrictions for instance, minimum wall thickness, maximum angulation, cementable abutment post height etc. Standard connecting geometries e.g., abutment to implant interface are also defined in the library which cannot be edited by a user. Any dental implantborne restoration can only be created within the 510(k)-cleared design envelope.

    The output of the CAD software is a three-dimensional geometry file which is linked to meta data like material and patient identifier.

    All designed implant-borne restorations are intended to be:

    • sent to Straumann for manufacturing by a validated milling center, or .
    • milled on a validated Straumann C series or M series milling machine (only . with the CARES Visual software, K171649 and K203456)
    • 3D printed as a temporary crown, or temporary bridge (up to 180 days) using P pro . Crown & Bridge material on a validated Straumann P series printer (only with the CARES Visual software, K203750)

    Straumann CARES Visual/Nova has no patient contact since it is software.

    AI/ML Overview

    The provided text is a 510(k) summary for the Straumann CARES Visual and Nova Dental CAD software. This document outlines the device's indications for use, its technological characteristics, and a comparison to predicate devices, but lacks detailed performance study information with numerical acceptance criteria and measured performance.

    Here's an analysis of the requested information based on the provided text:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document mentions "Performance Testing - Bench" and "Software verification and validation testing," indicating that tests were performed to demonstrate that the software adheres to design specifications and restrictions. However, it does not provide specific numerical acceptance criteria (e.g., accuracy percentages, dimensional tolerances) or their corresponding numerical performance results.

    Instead, the acceptance criteria are implicitly described as:

    • The software effectively controls design specifications and material selections for compatible abutment design libraries that undergo separate 510(k) clearance.
    • Restrictions prevent the design of patient-matched components outside of allowable design limitations.
    • Design limitations and specifications of compatible implant-abutment design libraries are locked and cannot be modified by the end user.

    The reported performance is a general statement that these tests were "provided to demonstrate" and "conducted to demonstrate" these aspects. No quantitative measurements are included.

    2. Sample Size Used for the Test Set and Data Provenance

    The text does not specify the sample size used for the test set or the provenance of any data (e.g., country of origin, retrospective/prospective). It only refers to "representative screenshots under user verification testing," which suggests qualitative evaluation rather than quantitative statistical analysis on a defined dataset.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

    The document does not mention the use of experts to establish ground truth for a test set. The validation appears to be centered on the software's functionality and adherence to predefined design rules rather than a comparison to expert-derived ground truth on clinical cases.

    4. Adjudication Method for the Test Set

    As there's no mention of experts establishing ground truth or evaluating cases, there is no adjudication method described.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

    No MRMC comparative effectiveness study is mentioned. The device is CAD software for designing dental prosthetics, which is different from an AI-assisted diagnostic tool where human reader performance would typically be assessed.

    6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

    The performance testing described is inherently standalone from a human-in-the-loop perspective, as it verifies the software's ability to enforce design rules and generate valid geometry files. The software's output (geometry file) is then used for manufacturing. The device inherently functions "without human-in-the-loop performance" in terms of its core design rule enforcement, although a human user still operates the software to create the design.

    7. The Type of Ground Truth Used

    The ground truth for this device appears to be primarily predefined design specifications and limitations based on engineering rules, material properties, and anatomical considerations for dental prosthetics. The software's internal logic and libraries incorporate these rules. It's not based on expert consensus, pathology, or outcomes data in the typical sense of a diagnostic or predictive AI.

    8. The Sample Size for the Training Set

    The document does not mention a training set for the software. This suggests that the software is likely rule-based CAD software rather than a machine learning or AI model that requires a training set of data. Its functionality is based on programmed algorithms and predefined libraries ("design envelope").

    9. How the Ground Truth for the Training Set Was Established

    Since no training set is mentioned, this point is not applicable.

    Intended Use

    The BTI Dental Implant System UnicCa® for oral implant surgery is to be used for the partial or total replacement of teeth in edentulate patients. Once attached to the bone, the implants act as an anchor for various fixed or removable prosthetic solutions that can be used to improve or restore a patient's mastication function.

    In the case of 5.5 - 6.5mm long UnicCa® implants should be used in a two-stage surgical procedure. These implants are indicated for delayed loading. These implants are indicated only for straight abutments and to support permanently fixed restorations.

    In the case of Tiny® 3.0 UnicCa® implants: These implants shall be used only to replace maxillary lateral incisors and mandibular lateral and central incisors. Immediate loading is recommended when there is good primary stability and an appropriate occlusal load.

    Device Description

    BTI Dental Implant System UnicCa® is a self-tapping, threaded, root form dental titanium implant provided in two types of connections: external (i.e., Externa®) and interna®), in a variety of platforms and range of diameters (3.0 – 6.0 mm) and lengths (5.5 – 18.0 mm). BTI Dental Implant System UnicCa® features an implant surface treatment that improves the hydrophilicity of the implant.

    The purpose of this 510(k) is to expand the product offering and include a new dental implant platform (Interna Narrow), and compatible abutments, together with additional implants for the already existing Universal Plus platform. Interna Narrow implants will be offered with implant diameters ranging from 3.3 to 4.75 mm and lengths of 5.5 to 15 mm.

    Intended Use

    The Straumann CARES P-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, a restorative acrylic resin, 3D printers, post-curing unit and associated accessories. The system is used to design and fabricate CAD/CAM 3D printed coping, crown and bridge restorations to be cemented onto Straumann® Variobase® Abutments that are affixed to the endosseous dental implants of the Straumann® Dental Implant System using a basal screw.

    The Straumann P pro Crown & Bridge material in combination with the Straumann Variobase is indicated for temporary (up to 180 days) dental restoration of a Straumann dental implant.

    Device Description

    The Straumann CARES P-Series CAD/CAM System is intended for the design and fabrication of dental restorations by dental laboratories by means of a digital workflow for 3D printing.

    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.

    AI/ML Overview

    The provided text is a 510(k) summary for the Straumann CARES P-Series CAD/CAM System. It primarily focuses on demonstrating substantial equivalence to a predicate device rather than providing a detailed study that proves the device meets specific acceptance criteria in the manner of a clinical trial or performance study comparing a new algorithm's efficacy.

    Therefore, much of the requested information regarding acceptance criteria, sample sizes, expert ground truth, MRMC studies, standalone performance, and training set details for an AI/algorithm-based device is not explicitly available in this document. The device in question is a CAD/CAM system for designing and fabricating dental restorations, not an AI diagnostic tool.

    However, based on the provided text, here's what can be extracted and inferred:

    1. Table of Acceptance Criteria and Reported Device Performance

    The document does not present a formal table of "acceptance criteria" for a specific performance metric in the context of an AI algorithm. Instead, it describes "Design Specifications" which serve as internal parameters for the CAD/CAM system and performance testing related to mechanical properties.

    FeatureAcceptance Criteria (Implicit from Predicate & Testing)Reported Device Performance
    Minimum wall thickness (Crown)Sufficient for intended use (compared to predicate)1.0 mm
    Maximum angulation (Crown)Safe and effective (compared to predicate)30°
    Minimum post-height of VariobaseSufficient for intended use (compared to predicate)4.6 mm
    Minimum diameterSufficient for intended use (compared to predicate)3.8 mm
    Maximum number of units (Bridge)Specified by material manufacturer (compared to predicate)6 units
    Maximum number of pontics (Bridge)Specified by material manufacturer (compared to predicate)2 pontics
    Mechanical PropertiesEquivalent to primary predicate and reference devicesDynamic fatigue and static strength tests passed
    BiocompatibilityMet for P pro Crown & Bridge material (K200039)Biocompatibility tests passed (cytotoxicity, sensitization, irritation)
    Sterilization ProcessValidated according to FDA guidanceValidated for Straumann Variobase®
    Software RestrictionsPrevent design outside allowable limitationsDemonstrated effective use; limitations locked
    3D Printer System AccuracyDesign input matches output; repeatable; independent of factorsDesign input matched output; repeatable; independent of print orientation, build plate location, material reuse (up to 30 times)

    2. Sample Size Used for the Test Set and Data Provenance

    This information is not provided in the document. The testing described primarily involves mechanical material testing and software verification, not clinical or diagnostic data analysis. Therefore, concepts like "test set" in the context of an AI algorithm are not applicable here.

    3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications

    This information is not applicable as the document describes a CAD/CAM system for fabricating dental prosthetics, not a diagnostic AI algorithm requiring expert ground truth for imaging or clinical decision support. The "ground truth" for the mechanical characteristics would be established by standardized testing protocols.

    4. Adjudication Method for the Test Set

    This information is not applicable for the same reasons as in point 3.

    5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

    This information is not applicable. The device is a CAD/CAM system for fabrication, not an AI for human reader assistance or diagnostic interpretation.

    6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done

    The "standalone" performance described relates to the verification of the 3D printer system and the CAD software.

    • Software Verification and Validation: This was performed to demonstrate that the software's restrictions prevent designing components outside allowable limitations and that the design library is locked. This implies a standalone verification of the software's adherence to design rules.
    • 3D Printer System Verification: This confirmed that "the design input matched the output, that the process is repeatable and independent of print orientation, build plate location effects, and the effects of material reuse." This is a form of standalone performance assessment for the manufacturing component.

    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

    The "ground truth" for the performance testing cited appears to be:

    • Standardized Mechanical Testing: According to FDA guidance for dental implants and abutments. This involves objective measurements of strength and fatigue.
    • Material Specifications: Biocompatibility data from a previously cleared 510(k) for the P pro Crown & Bridge material (K200039).
    • Design Specifications: Defined parameters (e.g., minimum wall thickness, maximum angulation) that the CAD software must adhere to.

    This is not "expert consensus, pathology, or outcomes data" in the typical sense of AI diagnostic systems.

    8. The sample size for the training set

    This information is not provided and is not applicable as the device is not an AI/machine learning algorithm requiring a "training set" in the conventional sense.

    9. How the ground truth for the training set was established

    This information is not provided and is not applicable for the same reasons as in point 8.

They are placed out of occlusion and have a maximum duration of usage of 180 days. Unlike the predicate RB/WB healing abutments (K173961), the subject healing abutments are intended to shape the soft tissue for posterior placement of bridge restorations instead of single crowns. The subject healing abutments are manufactured from Titanium Grade 4 and are anodized in violet.

    BLX Temporary Abutments for Bars and Bridges: Temporary Abutments are intended to be placed into Straumann dental implants to provide support for temporary restorations. Temporary components can be used prior to the insertion of the final components to maintain, stabilize and shape the soft tissue during the healing phase, as well as provide a temporary esthetic solution. They support a temporary restoration and may not be placed into of occlusion. Straumann BLX Temporary Abutments have a maximum duration of usage of 180 days. Unlike the predicate RB/WB temporary abutments (K173961), the subject temporary abutments are intended to shape the soft tissue for posterior placement of bridge restorations instead of sinqle crowns. The subject temporary abutment cannot be shortened. The Temporary abutment for bar/bridge is a non-engaging device intended to support multiple-unit restoration. The subject temporary abutment is manufactured from TAN and is anodized in violet. The temporary abutments are fixed in the implant by means of a basal screw which is also manufactured from TAN.

    BLX Variobase Abutments for Bars and Bridges: Variobase Abutments for Bars and Bridges are intended to be placed into Straumann implants to provide support for multi-unit restorations. The prosthetic restoration (bar/bridge) must be cemented onto the Variobase abutments, which is then screwed onto the implants. A temporary restoration can be used prior to the insertion of the final components to maintain, stabilize and shape the soft tissue during the healing phase; they must be placed out of occlusion. Final abutments and restorations may be placed into occlusion when the implant is fully osseointegrated. Unlike the predicate Variobase abutments (K173968), the subject Variobase abutments present 3 retention features in the chimney instead of 4. The Variobase abutments for bar/bridges are non-engaging devices intended to support multiple-unit restorations. The subject Variobase abutments are manufactured from TAN and are anodized in violet. The Variobase abutments are fixed in the implant by means of a basal screw which is also manufactured from TAN.

    BLX Variobase Abutments AS for Crowns: Variobase abutments AS for crowns are intended to be placed into Straumann implants to provide support for single-unit restorations. The prosthetic restoration (crown) must be cemented onto the Variobase abutment, which is then screwed onto the implant. A temporary restoration can be used prior to the insertion of the final components to maintain, stabilize and shape the soft tissue during the healing phase; they must be placed out of occlusion. Final abutments and restorations may be placed into occlusion when the implant is fully osseointegrated. The Variobase abutments are manufactured from TAN and are anodized in violet or in brown according to the compatible BLX implant platform (RB/WB or RB). Unlike the predicate Variobase abutments (K173961/K173379), the subject Variobase abutments present 3 retention features in the chimney instead of 4. The chimney presents a cutout window to facilitate the handling of the screw driver in an angulated position. The Variobase abutments AS for crown are engaging devices intended to support single-unit restorations. The Variobase abutments are fixed in the implant by means of a basal screw which is also manufactured from TAN. The Variobase abutments for crown AS 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 planning and milling of the customized restoration must be made using the validated Straumann CARES Visual, Dental Wings software using the Straumann CARES Visual Plug-In. All digitally designed copings and/or crowns for use on the Variobase abutments are intended to be manufactured at a validated milling center.

    BLX Novaloc Abutments: Novaloc Abutments are intended to be placed into Straumann dental implants to provide support for full arch detachable restorations (over-denture). The Novaloc abutments are manufactured from TAV (Ti-6Al-4V, Titanium-Aluminum-Vanadium) and are anodized in violet. The restoration is connected to the Novaloc abutment through a snap-on fixture provided by a negative shape of Novaloc snap-on fixture embedded into the final restoration. The snap-on feature is TiN coated. Unlike the reference Novaloc abutments (K173902), the subject Novaloc abutments are not only provided in a straight version but also angulated. The Novaloc abutments are provided non-sterile with instructions for end user sterilization. Angled models: are composed of an abutment body with a coupled basal screw. They are engaging devices. Straight models: both body and thread parts are machined in one piece. They are nonengaging devices.

    BLX CARES Abutments: CARES Abutments are intended to be placed into Straumann implants to provide support for prosthetic reconstructions such as crowns and bridges. The final abutment, fabricated from a pre-milled blank, is designed to allow for individual customization regarding function and esthetics. The blank, manufactured from TAN and CoCr, is composed of a pre-milled implant-toabutment connection (TorcFit) and a cylindrical body with enough material volume to create a wide range of geometries for the final abutment. Inside the abutment, a screw channel provides access to the internal thread feature of the implant, such that the component can be firmly attached while providing fit between screw, abutment and implant. The planning and milling of the customized restoration must be made using the validated Straumann CARES Visual, Dental Wings software using the Straumann CARES Visual Plug-In. The maximum angulation allowed is 30° and the minimum wall thickness allowed is 0.4 mm. All digitally designed abutments are intended to be manufactured at a validated milling center.

    BLX Basal Screws: Basal screws are used to fix abutments to dental implant, and can also be used during lab procedures to fix lab prosthetic parts on implant analogs. They are provided along the abutments and also provided as standalone screws. The subject Basal Screws are manufactured from TAN. The Basal Screw for Variobase AS is anodized in green since this color identifies Straumann devices pertaining to AS system.

    AI/ML Overview

    The provided 510(k) summary for the Straumann® BLX Line Extension - New Abutments is a pre-market notification to the FDA. This type of submission focuses on demonstrating substantial equivalence to existing legally marketed devices, rather than proving the device meets acceptance criteria through a traditional clinical study with defined performance targets.

    Instead of "acceptance criteria," the focus here is on bench testing performance demonstrating fundamental material and structural integrity compared to predicate devices, and lack of significant differences in technological characteristics and indications for use.

    Therefore, the requested information elements related to clinical studies, test sets, ground truth, and expert adjudication are not applicable in the context of this 510(k) summary, as no device-specific clinical data has been submitted to demonstrate substantial equivalence. The submission relies on performance data from bench testing and biocompatibility assessments to support the claim of substantial equivalence.

    Here's the information that can be extracted from the provided text, re-interpreting "acceptance criteria" as the comparable characteristics to predicate devices and "reported device performance" as the results of the bench and biocompatibility tests.


    Acceptance Criteria and Study Details for Straumann® BLX Line Extension - New Abutments

    As this is a 510(k) submission primarily relying on substantial equivalence to predicate devices, the concept of "acceptance criteria" is less about meeting specific numerical performance targets in a clinical setting and more about demonstrating that the new devices do not raise new questions of safety or effectiveness. The study supporting this is primarily bench testing and biocompatibility assessments, rather than a clinical trial.

    1. A table of acceptance criteria and the reported device performance

    The "acceptance criteria" for a 510(k) are implicitly that the new device's technological characteristics and performance are substantially equivalent to a predicate device, without raising new questions of safety or effectiveness. The "reported device performance" refers to the results of the bench tests and sterility/biocompatibility validations.
