## Indications for Use
Prosthetic components connected to the implant or abutment, are intended for use as an aid in prosthetic rehabilitation.
## Device Story
Straumann® PUREloc abutments are prosthetic components designed for use with overdentures or partial dentures retained by endosseous implants in the mandible or maxilla. The device consists of a Yttrium-stabilized zirconia ceramic abutment and a Titanium Grade 4 basal screw. It is used exclusively on Straumann PURE Ceramic Implants. The abutment features a snap-on connection for the denture. The device is intended for use by dental professionals in a clinical setting to aid in prosthetic rehabilitation. The healthcare provider selects the appropriate abutment size (1-6 mm heights) to fit individual patient needs, secures it to the implant via the basal screw, and attaches the denture. This system provides a retentive interface for dental prosthetics, facilitating patient function and aesthetics.
## Clinical Evidence
No clinical data. Bench testing only. Biocompatibility evaluated per ISO 10993-1, -5, -12, and -18. Mechanical performance validated via dynamic fatigue, snapping force, and dynamic force testing per FDA guidance for root-form endosseous dental implants and abutments.
## Technological Characteristics
Material: Yttrium-stabilized zirconia ceramic (ISO 13356). Basal screw: Titanium Grade 4. Connection: Non-engaging, screw-retained to implant; snap-on to restoration. Dimensions: 4.8 mm diameter; 1-6 mm gingival heights. Sterilization: Non-sterile, end-user sterilized. MRI compatibility: MRI conditional.
## Regulatory Identification
An endosseous dental implant abutment is a premanufactured prosthetic component directly connected to the endosseous dental implant and is intended for use as an aid in prosthetic rehabilitation.
## Special Controls
*Classification.* Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)

Dear Jennifer Jackson:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls.

### 5.4 Device Description
The Straumann® Retentive System (to which PUREloc belongs) is designed for the use with overdentures or partial dentures, retained in whole or in part, by endosseous implants in the mandible or maxilla. The Straumann® Retentive System consists of abutments which are used for the restoration of Straumann dental implants of different types, endosteal diameters, lengths and platforms. They are available in different sizes and angles to fit individual patient needs. Straumann® PUREloc abutments are used exclusively on the Straumann PURE Ceramic Implants, are available in 6 heights (1 mm, 2 mm, 3 mm, 4 mm, 5 mm, and 6 mm) and made of Yttrium-stabilized zirconia ceramic (ISO 13356 - Implants for surgery -- Ceramic materials based on yttria-stabilized tetragonal zirconia (Y-TZP)). The Straumann® PUREloc abutments are non-engaging and the implant-to-abutment connection is provided for by the basal screw. The basal screw is manufactured from Titanium Grade 4 and is identical to the basal screw cleared under K180477.

Table 1 – Comparison of subject device versus primary predicate device and reference predicate device
{9}------------------------------------------------
## Straumann® PUREloc Abutments
The primary predicate (K190040) is included for reference to the Straumann BLX Novaloc Abutments. The indications for use for the primary predicate contains reference to many different types of abutments. The intended use and indications for use of the subject device are identical to the Straumann BLX Novaloc Abutments. Dimensionally, the platform diameter is slightly smaller for the subject device to accommodate the implant diameter of the compatible implants. The material of the subject device is identical to the implants of the reference device (K180477) and the screw used to secure the abutment to the implant is identical to the basal screw cleared under K180477. The reference device (K190662) is included in support of considerations for MRI compatibility.
## 5.8 Performance Testing
### 5.8.1 Sterilization
The sterilization process for the PUREloc abutments as recommended in the labeling was validated according to applicable recommendations in the FDA guidance document "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling, issued on March 17, 2015".
## 5.8.2 Biocompatibility
The subject device materials were evaluated for biocompatibility according to ISO 10993-1:2009 "Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process" and the biocompatibility evaluation flow chart according to the FDA Guidance document "Use of International Standard ISO 10993-1, 'Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process', Guidance for Industry and Food and Drug Administration Staff, Document issued on: June 16, 2016".
Although the subject devices materials are identical to the primary predicate and reference devices, cytotoxicity and chemical characterization tests were performed due to differences in geometry, manufacturing processes, and sterilization processes to confirm biocompatibility. These tests were conducted according to ISO 10993-5, 10993-12, and 10993-18 and confirmed the subject devices are biocompatible.
{10}------------------------------------------------
# Straumann® PUREloc Abutments
#### Bench testing 5.8.3
Dynamic fatigue was conducted according to the FDA guidance document "Guidance for Industry and FDA Staff – Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments", furthermore snapping force, and dynamic force tests were performed and demonstrated that the PUREloc abutments are identical to primary predicate (K190040) in terms of performance.
## 5.9 Conclusion
The documentation submitted in this premarket notification demonstrates the PUREloc abutments are substantially equivalent to the primary predicate and reference devices.
