The implants are intended for both one- and two-stage surgical procedures in the following situations and with the following clinical protocols:

• · Replacing missing teeth in single or multiple unit applications in the mandible or maxilla.
• · Immediate placement in extraction sites and in situations with a partially or completely healed alveolar ridge.
• · Especially indicated for use in soft bone applications with other implant surface treatments may be less effective.
  • Immediate and early loading for all indications, except in single tooth situations on implant shorter than 8 mm or in soft bone (type 4) where implant stability may be difficult to obtain, and immediate loading may not be appropriate.
  · The intended use for PrimeTaper EV Ø3.0 is limited to replacement of maxillary lateral incisors and mandibular incisors.

DS Implants abutments provided with the EV connection are intended to be used in conjunction with implants with the EV connection in fully edentulous or partially edentulous maxillary and/or mandibular arches to provide support for crowns, bridges or overdentures.

MultiBase Abutments EV:
DS Implants abutments provided with the EV connection are intended to be used in conjunction with implants with the EV connection in fully edentulous or partially edentulous maxillary and/or mandibular arches to provide support for bridges or overdentures.

The proposed (A) PrimeTaper EV Dental Implant Ø3.0 is a root form endosseous implant which is intended for use by a dental clinician in the prosthetic restoration of chewing function in edentulous human jaws. It represents an additional extra small implant diameter implant) to reference device PrimeTaper EV Dental Implants (K210610).

The proposed (A) PrimeTaper EV Dental Implant Ø3.0 has the identical implant-abutment connection geometry as the predicate (A) Astra Tech EV Implant (K120414), and is therefore compatible with the reference device Astra Tech EV Abutments (K120414) with 3.0 mm diameter of the Astra Tech Implant System EV (K120414).

The proposed (B) DS Implant abutments with EV connection XS include the following abutments and accessories:

• TiDesign EV (XS) ●
• MultiBase Abutment EV (XS) ●
• . TempAbutment EV (XS)
• Healing Abutment EV (XS) ●
• HealDesign EV (XS) ●
• Cover Screw EV (XS)
• Abutment Screw EV (XS) ●

The proposed (B) DS Implants abutments with EV connection XS are used in conjunction with an endosseous dental implant with EV connection to aid in prosthetic rehabilitation in fully edentulous or partially edentulous maxillary and/or mandibular arches. They are prosthetic abutments compatible with the proposed (A) PrimeTaper EV Dental Implant Ø3.0 and represent an additional extra small abutment-implant diameter (XS, 3 mm diameter) to the Predicate (B) DS Implants abutments with EV Connection in sizes S (small), M (medium) and L (large) (K213449).

The proposed (B) abutments have the identical implant-abutment connection geometry as the reference device Astra Tech EV Abutments (K120414) and are therefore compatible with the predicate (A) Astra Tech EV Implants (K120414) with 3.0 mm diameter.

The proposed (A) PrimeTaper EV Dental Implant Ø3.0 and proposed (B) DS Implants abutments with EV connection XS are single-use devices and are provided sterile by electron-beam irradiation except for TiDesign EV (XS). TempAbutment EV (XS) and Abutment Screw (XS), which are provided non-sterile. Devices provided as non-sterilized by the end user via steam sterilization.

The document provided is a 510(k) summary for Dentsply Sirona's PrimeTaper EV Dental Implants Ø3.0 and DS Implants abutments with EV connection (XS). It describes the devices, their intended use, and substantial equivalence to predicate and reference devices based on non-clinical performance data and published literature.

Here's a breakdown of the requested information:

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

The document does not explicitly state "acceptance criteria" in a quantitative manner with specific thresholds. Instead, it relies on demonstrating that the proposed devices (PrimeTaper EV Dental Implants Ø3.0 and DS Implants abutments with EV connection XS) are substantially equivalent to legally marketed predicate devices. The performance is assessed by confirming that the proposed devices satisfactorily meet the requirements of non-clinical bench testing and aligning with published clinical data on similar devices.

However, based on the non-clinical testing performed, we can infer performance criteria against established standards:

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

• Non-clinical Testing (Bench Tests): The document refers to "worst-case implant-abutment combination" for fatigue testing but does not specify the exact number of samples tested for each non-clinical performance test (e.g., fatigue, biocompatibility, sterilization validation, MRI). It is implied that sufficient samples were tested to meet the requirements of the respective ISO and ASTM standards.
• Clinical Literature:
  • Sample Size: 200 narrow diameter implants (OsseoSpeed 3.0 mm, Astra Tech Implant System (K080396)) were evaluated. These implants were placed in "over 160 patients."
  • Data Provenance: The data is from "six peer-reviewed scientific publications" presenting "1 to 5 years of clinical follow-up data from four (4) different clinical trials." The country of origin is not specified but it relates to published peer-reviewed scientific literature. The studies were prospectively followed up.

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)

This section is not applicable to this submission. The "ground truth" in this context is established through compliance with recognized international standards (ISO, ASTM) for non-clinical testing and clinical outcomes reported in peer-reviewed literature, rather than expert adjudication of a test set in the way one might see for an AI algorithm.

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

Not applicable. This is not an AI/imaging device where expert adjudication for ground truth establishment is typically performed.

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 submission is for dental implants and abutments, not an AI-assisted diagnostic or therapeutic device.

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

Not applicable. This is not an AI/algorithm-based device.

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

• Non-clinical Testing: The "ground truth" for non-clinical performance (sterilization, biocompatibility, fatigue, MRI safety, pyrogenicity, packaging) is defined by established international standards (ISO, ASTM) and FDA guidance documents. The device's performance is measured against these technical standards.
• Clinical Performance (via literature): The "ground truth" is based on outcomes data (survival rates, marginal bone maintenance) reported in peer-reviewed clinical literature.

8. The sample size for the training set

Not applicable. This is not an AI/machine learning device that requires a training set.

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

Not applicable. This is not an AI/machine learning device.
