Intended Use

The Straumann® PURE Ceramic Implant (Monotype) is indicated for restoration in single tooth gaps and in an edentulous or partially edentulous jaw. The prosthetic restorations used are single crowns, fixed partial or full dentures, which are connected to the implants through the corresponding components. The ø3.3 mm reduced diameter implants are recommended for central and lateral incisors only.

Device Story

Straumann® PURE Ceramic Implants are endosseous dental implants made of 100% yttrium-stabilized zirconia (Y-TZP). The device features a monotype design with an integrated ceramic abutment and a ZLA (sand-blasted, large-grit, acid-etched) surface to promote osseointegration. Used by dental professionals in clinical settings to support single crowns, fixed partial, or full dentures. The implant is surgically placed into the jawbone to replace missing teeth. The device is provided sterile via Ethylene Oxide (EO) sterilization. The clinician selects the appropriate diameter and length based on the patient's anatomical needs. The output is a stable, biocompatible foundation for prosthetic dental restorations, benefiting patients by restoring oral function and aesthetics.

Clinical Evidence

Bench testing only. No clinical data provided. Validation included sterilization per ISO 11135 (SAL 10-6), packaging integrity (ISTA 2A), shelf-life (ASTM F1980), and biocompatibility (ISO 10993-1). Mechanical testing (static, dynamic fatigue, torque) performed per ISO 14801:2007 confirmed performance consistency after hydrothermal aging. Surface chemistry analysis showed no significant differences between sterilization methods.

Technological Characteristics

Material: 100% yttrium-stabilized zirconia (Y-TZP). Surface: ZLA (sand-blasted, large-grit, acid-etched). Design: Cylindrical monotype with 1.8 mm machined neck. Dimensions: Apical diameters 3.3/4.1 mm; coronal diameters 3.5/4.8 mm; lengths 8-14 mm. Thread pitch: 0.8 mm. Sterilization: Ethylene Oxide (ISO 11135).

Indications for Use

Indicated for patients requiring dental restoration in single tooth gaps or edentulous/partially edentulous jaws. Reduced diameter (ø3.3 mm) implants restricted to central and lateral incisors.

Regulatory Classification

Identification

An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore a patient's chewing function.

510(k) Summary

### 5.7 Performance Data

The following performance data were provided in support of the substantial equivalence determination.

### Sterilization and Shelf-Life

A sterilization validation was performed per ISO 11135, Sterilization of healthcare products – Ethylene Oxide – Requirements for development, validation and routine control of a sterilization process for medical devices, using the Half Cycle Overkill Approach. The validation demonstrates that the sterilization process and equipment is capable of reliably and consistently sterilizing the subject device to a minimum Sterility Assurance Level (SAL) of 10-6.

A transportation study has been performed per ISTA 2A to demonstrate the integrity of the sterile barrier system considering the new sterilization process. The subject devices continue to meet product release requirements after being subjected to worst-case environmental and handling changes.

A packaging stability study was performed to demonstrate the integrity of the packaging system and the sterile barrier system after sterilization process via Ethylene Oxide,

handling, distribution, transport and storage up to the defined product shelf life. The subject devices continue to meet product release requirements after being subjected to worst-case environmental and handling changes.

Shelf-Life studies have been conducted in accordance with ASTM F1980.

### Biocompatibility Testing

The biological safety of the Straumann® PURE Ceramic Implants sterilized via Ethylene Oxide was re-evaluated and further biocompatibility testing was required according to ISO and FDA standard (FDA, 2016; ISO 10993-1, 2009). EO and ECH residues were not detected in the chemical analysis and no cytotoxicity was observed. Based on the test results the change in sterilization method did not affect the biological safety profile of the devices.

### Bench Testing

Mechanical testing (static, dynamic fatigue and torque) and surface chemistry analysis was performed to demonstrate the new sterilization method does not affect product performance. Static and dynamic fatigue strength testing was performed per ISO 14801:2007 and the FDA-Guidance to "Root-form endosseous dental implants Straumann USA, LLC November 14, 2017

{7}------------------------------------------------

### 510(k) Summary

and endosseous dental implant abutments." All mechanical testing performed demonstrated the new sterilization method does not affect the product performance after being subjected to hydrothermal aging. Cleanliness analysis demonstrated no significant difference in surface chemistry between H2O2 plasma (sterility method per predicate device) and EO sterilization.

### 5.8 Conclusion

The documentation submitted in this premarket notification demonstrates that the Straumann® PURE Ceramic Implants are substantially equivalent to the predicate device and do not pose new issues of safety and effectiveness.
