Temporary components can be used prior to the final components to maintain, stabilize and shape the soft tissue during the healing phase; they are to be placed out of occlusion. Final abutments may be placed into occlusion for implants with sufficient primary stability or for implants that are fully osseointegrated.

Temporary Abutments have a maximum duration of usage of 180 days.

Device Description

The subject devices described in the submission are prosthetic components that are intended for use in prosthetic rehabilitations, directly or indirectly connected to the endosseous dental implant. These devices are intended for use as an aid in prosthetic rehabilitations. The subject devices described in this submission are to be added Straumann's existing prosthetic portfolio.

AI/ML Overview

The provided text is a 510(k) summary for Straumann® Screw-Retained Abutments. This document primarily focuses on demonstrating substantial equivalence to previously cleared predicate devices through comparisons of technological characteristics and performance data, mainly bench testing and biocompatibility assessments. It explicitly states that no device-specific clinical data has been submitted.

Therefore, the information required to describe acceptance criteria and a study proving the device meets those criteria, especially in the context of an AI/human reader study or performance metrics typical for AI devices (like sensitivity, specificity, AUC), is not present in this document.

This document describes a traditional medical device (dental implants and abutments) cleared via the 510(k) pathway, which fundamentally relies on demonstrating substantial equivalence to a predicate device, rather than proving performance against specific acceptance criteria through novel clinical studies or AI algorithm validation.

To address the user's request, I must state that the information is not available in the provided document, as it pertains to a different type of device and regulatory submission pathway.

Specifically, the document states:

  • "No device specific clinical data has been submitted to demonstrate substantial equivalence." (Page 12, Section 5.7.4)

Here's an explanation with respect to the user's request:

  1. A table of acceptance criteria and the reported device performance: Not applicable. The submission focuses on substantial equivalence through comparison with predicates, not on meeting predefined performance metrics from a study in the way an AI/software device would. The "performance data" refers to bench testing (dynamic fatigue, static strength, torque) and biocompatibility, which are compared to predicate devices rather than against specific numerical acceptance criteria.

  2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): Not applicable, as no clinical study (with test sets of patient data) was conducted or submitted. The 'samples' referred to in bench testing are physical abutment components.

  3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for clinical data involving human perception (like AI for image analysis) is not relevant here as no such clinical study was performed.

  4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.

  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: Not applicable. This is not an AI-powered device.

  6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an AI-powered device.

  7. The type of ground truth used (expert concensus, pathology, outcomes data, etc): Not applicable.

  8. The sample size for the training set: Not applicable. This is not an AI-powered device with a training set.

  9. How the ground truth for the training set was established: Not applicable.

In summary: The provided 510(k) summary for Straumann® Screw-Retained Abutments does not contain the type of AI/clinical performance study information requested. The device is a traditional medical device (dental implant components) and its clearance is based on substantial equivalence to predicate devices, verified through bench testing and biocompatibility assessments, not through human reader studies or AI algorithm performance evaluations on clinical datasets.

5.6 Technological Characteristics

5.6.1 Straumann® Screw-Retained Abutments

The straight and smoothened angled Screw-Retained Abutments are made of Ti-6Al-7Nb (TAN) and designed to be used together with Straumann® Bone Level Implants having either NC (Narrow CrossFit) or RC (Regular CrossFit) connections. SRAs are laser engraved with either NC or RC to specify the implant type. SRAs are anodized blue for NC Ø3.5 mm and yellow for NC Ø4.6 mm. RC abutments are non-anodized. SRA straight abutments do not contain an anti-rotational feature, allowing the abutment to be screwed directly into the implant. Smoothened angled SRAs are connected to the implant by a basal screw. The proposed abutments will be delivered to the end user sterile via gamma irradiation.

The proposed Screw-Retained Abutments are equivalent to the Screw-Retained Abutments cleared per K133421 and K171757. The proposed Screw-Retained Abutments production processes are identical to screw-retained abutments cleared per K171757 with a new design. The new design, straight Screw-Retained Abutments and smoothened angled Screw-Retained Abutments for Bone Level Implants are similar in regards to design to the Screw-Retained Abutments for BLX cleared per K181703. Premarket notification K190662 is included as a reference device to address MRI compatibility. Premarket notification K072497 is included as a reference device for comparison of dynamic fatigue.

510(k) Summary

5.6.2 Straumann® Temporary Copings for Screw-Retained Abutments

Temporary Copings are placed on dental abutments to support temporary prosthetic superstructures. Temporary copings in combination with the implant, abutment and temporary superstructure are used to restore function in patients missing a tooth or teeth for a temporary period. This commonly occurs during the healing and soft tissue management phase after implants are placed. Temporary restorations are not intended for receiving occlusal load from opposing dentition. This temporary solution to a missing tooth is later replaced by the final restoration.

The proposed temporary coping is designed for easier reworking at the dentist office. The proposed temporary coping will have a reduced wall thickness than temporary copings cleared per K133421.

The technological characteristics of the proposed Screw Retained Abutments are compared to the primary and reference devices in Table 2.

5.6.3 Straumann® Protective Caps for Screw-Retained Abutments

Protective caps are placed to the Screw-Retained Abutment and intended to be used to protect the abutment configuration and maintain, stabilize and form the soft tissue during the healing process. The proposed protective caps are made available with a width of 3.5 mm and 4.6 mm. The proposed protective caps are similar to the protective caps cleared per K133421 for Screw-Retained Abutments. The difference is a change in design from a columnar shape to a mushroom shape of the polymer body. The proposed protective caps are made out of PEEK and a screw made out of titanium alloy. The proposed protective caps are to be provided to the end user as non-sterile.

The technological characteristics of the proposed Screw Retained Abutments are compared to the primary and reference devices in Table 3.
