Intended Use

The TIB Abutments are premanufactured prosthetic components directly connected to endosseous dental implants and are intended for use as an aid in prosthetic rehabilitation.

Device Description

This submission includes two major components which make up the TIB Abutment Base and the mesostructure restoration.

The TIB Abutment base is a standard premanufactured titanium alloy abutment for supporting a dental restoration and mesostructure. The dental laboratory is to fabricate the mesostructure restoration by CAD/CAM technique out of zirconia. The TIB abutment base then serves as the interface between the endosseous implant and the zirconia restoration. The TIB Abutment Base is designed to support the restoration on an endosseous implant in order to restore chewing function for the patient.

The mesostructured restoration is a CAD/CAM designed prosthesis milled out of zirconia, which is designed to fit the abutment base in order to restore chewing for the patient. Each restoration is custom designed using 3Shape Abutment Designer Software in order to meet the requirements of each patient on a case by case basis. Limitations have been put in place in 3Shape Abutment Designer in order to prevent malfunctioning of the restoration.

The TIB Abutments are compatible with the Southern Implants' Deep Conical, External Hex, Provata and Tri-Nex implants and screws. The TIB abutment bases are manufactured from Titanium alloy conforming to ASTM F136 and are color coded by gold anodizing. The anodization process is the same as used for previously cleared anodized titanium alloy devices in K163634. The Mesostructure restoration is to be manufactured from Zirconia - Sage Max NexxZr which has been previously cleared for use in K 130991.

The digital workflow includes the following products (not subject devices to this submission):

  • Ceramic material: Sage Max NexxZr Zirconia Restorative material (K130991)
  • Cement: Ivoclar Vivadent Multilink Hybrid Abutment Cement (K130436)
  • Desktop scanner: 3Shape E3 Desktop Scanner is 510(k) exempt under regulation . 872.3661)

AI/ML Overview

The provided text describes the TIB Abutment System and its performance data to demonstrate substantial equivalence to predicate devices, rather than establishing acceptance criteria and proving the device meets those criteria through a study with specific performance metrics.

Therefore, I cannot populate the table or answer questions 2 through 7 directly from the provided text as the document does not present acceptance criteria in a quantitative format, nor does it detail a standalone study with performance metrics for the TIB Abutment System against such criteria. Instead, it relies on comparative equivalence with already cleared devices and various non-clinical tests.

However, I can extract information related to the performance data and ground truth establishment that were conducted as part of the substantial equivalence demonstration.

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

The document does not explicitly state quantitative "acceptance criteria" and "reported device performance" for the TIB Abutment System in a format that would fit a table like the one requested. Instead, it relies on demonstrating substantial equivalence to predicate devices through various non-clinical tests and comparisons. The performance data listed are primarily compliance tests against recognized standards rather than specific device performance metrics against predefined thresholds.

2. Sample sizes used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective):

The document does not specify sample sizes or data provenance (country of origin, retrospective/prospective) for the non-clinical tests mentioned. It only lists the types of tests performed.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience):

Not applicable. The document refers to non-clinical tests and compliance with standards, not expert-adjudicated ground truth.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:

Not applicable. The document refers to non-clinical tests and compliance with standards, not expert adjudication.

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 a dental abutment system, not an AI-assisted diagnostic device, and no MRMC study or AI-related effectiveness is mentioned.

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

The document describes non-clinical testing of the device components and workflow, which can be considered a form of standalone evaluation for the device itself. The types of standalone tests performed include:

  • Biocompatibility testing per ISO 10993-1 and ISO 10993-5.
  • Validated sterilization instructions per ISO 17665-2.
  • Software validation testing per FDA Guidance.
  • Scanning and milling validation.
  • Static and dynamic compression-bending to ISO 14801.
  • Mechanical ISO 14801 Fatigue Testing for implant platforms.

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

The "ground truth" in this context is established by adherence to recognized international standards and FDA guidance documents for medical device testing. For example:

  • Biocompatibility: ISO 10993-1 and ISO 10993-5 standards.
  • Sterilization: ISO 17665-2.
  • Software Validation: FDA Guidance Document for Off-The-Shelf Software Use in Medical Devices.
  • Mechanical Testing: ISO 14801.

8. The sample size for the training set:

Not applicable. This document describes a medical device (dental abutment system) and its non-clinical testing for substantial equivalence, not a machine learning model that requires a training set.

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

Not applicable, as there is no training set for a machine learning model mentioned.

The system integrates multiple components of the digital dentistry workflow: Scan files from desktop scanners, CAD software, CAM software, ceramic material, milling machine and associated tooling and accessories.

SUBJECT DEVICE DESCRIPTION

This submission includes two major components which make up the TIB Abutment Base and the mesostructure restoration.

The TIB Abutment base is a standard premanufactured titanium alloy abutment for supporting a dental restoration and mesostructure. The dental laboratory is to fabricate the mesostructure restoration by CAD/CAM technique out of zirconia. The TIB abutment base then serves as the interface between the endosseous implant and the zirconia restoration. The TIB Abutment Base is designed to support the restoration on an endosseous implant in order to restore chewing function for the patient.

The mesostructured restoration is a CAD/CAM designed prosthesis milled out of zirconia, which is designed to fit the abutment base in order to restore chewing for the patient. Each restoration is custom designed using 3Shape Abutment Designer Software in order to meet the requirements of each patient on a case by case basis. Limitations have been put in place in 3Shape Abutment Designer in order to prevent malfunctioning of the restoration.

The TIB Abutments are compatible with the Southern Implants' Deep Conical, External Hex, Provata and Tri-Nex implants and screws. The TIB abutment bases are manufactured from Titanium alloy conforming to ASTM F136 and are color coded by gold anodizing. The anodization process is the same as used for previously cleared anodized titanium alloy devices in K163634. The Mesostructure restoration is to be manufactured from Zirconia - Sage Max NexxZr which has been previously cleared for use in K 130991.

The Indications for Use Statement for the subject device is the same as that of the primary predicate device

K K 000 States 1.10 de same the comments of the shier der abies der abies deriver anders anderse anderse armer
The subject devier Listes in the market ber antier der seteller

The primary predicate and the subject device have the identical maximum angulation for t restoration and follow an equivalent design workflow. In the design workflow the primary predicate uses a different scanner but the same software to design the restoration. The design workflow differing with the scanner does not impact demonstrating substantial equivalence. The difference in scanner was shown to not affect substantial equivalence by way of software validation, scanning and milling validation, and static and dynamic compression-bending according to ISO 14801.

The subject device is also substantially equivalent to the primary predicate with reference to the abutment's restoration material with the subject and the primary predicate both making use of a ceramic composite riate performance testing on the ceramic component of the two-piece abutment. The both the subject device and primary predicate is a um Allov (ASTM

{8}------------------------------------------------

F136), the screw material is Titanium for both the subject and primary predicate. Both the subject and the primary predicate devices are provided non-sterile. Thus, the abutment materials and method provided of the subject device are substantially equivalent to that of the primary predicate. The different manufacturing and ceramic material comparison were addressed with biocompatibility testing per the FDA Guidance Document for Use of Standard ISO 10993-1. "Biological evaluation of medical devices – Partly Evaluation and testing within a risk management process", and validated sterilization instructions per the FDA Guidance Document for Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labelling.

The reference predicate K181359 is for substantial equivalence of the Subject Device screw thread, manufacturing workflow, abutment surface treatment and usage. The subject device makes use of the same screw threads as the reference device (K181359) with a difference of the 1-72 unf-2b (1.85mm) and M1.8 screw threads. The screw threads differing with the addition of intermediary screw threads does not impact demonstrating substantial equivalence, and this was shown with static and dynamic compression-bending according to ISO 14801.

In terms of the manufacturing workflow, the subject device makes use of the WorkNC CAM software and a Roland DWX51D milling unit. The reference device (K181359) Makes use of Zenotec CAM and Wieland-Zenotec Select milling unit. While both are different brands, both devices make use of CAM software, communicating with a milling unit. The manufacturing workflow differing with CAM software and milling unit brands does not impact demonstrating substantial equivalence, and this was shown by of software validation, scanning and milling validation, and dynamic compression-bending according to ISO 14801.

The reference device (K163634) is for substantial equivalence of abutment material, surface treatment and packaging methods. The subject device abutments are manufactured from Titanium alloy conforming to ASTM F136 and are color coded by anodizing. The anodization process is the same as that used for the reference device (K163634). Both the subject and the reference device are packaged with the same methods for single use. Thus, the material, surface treatment and packaging methods of the subject device is considered substantially equivalent to that of the reference device.

The reference predicate K111421 is for substantial equivalence of the compatible implant platforms. The subject device is designed to connect directly to the Southern Implants External Hex, Deep Conical and Tri-Nex connection types. While the reference device (K111421) is designed to connect directly to multiple different implant systems, which together encompass the same range of implant platform types as that of the subject device. This, with the addition of Mechanical ISO 14801 Fatigue Testing of all four implant platforms proves substantial equivalence of the compatible implant platforms.

The post height of the subject device is indicated to a minimum of 4.5mm. The primary predicate (K180899) is indicated to a minimum of 5.2mm, while the reference device (K181359) is indicated to a minimum of 4mm. The subject device post height lies between these two predicate minimums and is thus substantially equivalent.

Substantial equivalence of the subject device components in terms of biocompatibility is supported by the fact that materials are identical in formulation, processing, component interactions, and storage conditions to the predicate devices in K163634. Furthermore, biocompatibility testing per the FDA Guidance Document for Use of Standard ISO 10993-1, "Biological evaluation of medical devices – Part1: Evaluation and testing within a risk management process" was performed.

The inclusion of the 3Shape software (K151455) was validated with performance testing per the FDA Guidance Document for Off-The-Shelf Software Use in Medical Devices.

{9}------------------------------------------------

Overall the subject device has the following similarities to the predicate devices:

  • Has the same intended use
  • · Incorporates the same basic design
  • · Incorporates the same or very similar materials,
  • · Follows the equivalent design and manufacturing workflows,
  • · Incorporates the same abutment surface treatment and packaging
  • Has a similar fatigue limit

CONCLUSION

The subject device and the primary predicate have the same intended use, except for the different scanner. The subject device and predicate devices all incorporate the same materials and basic design. The subject device and the predicate devices are for substantial equivalence of surface treatment and patient usage, and are provided non-sterile. The subject device and the primary predicate follow the same design and manufacturing CAD/CAM workflows.

The data included in this submission demonstrates substantial equivalence to the predicate devices listed above.
