Intended Use
Straumann BLX Implants are suitable for endosteal implantation in the upper and lower jaw and for the functional and esthetic oral rehabilitation of edentulous and partially edentulous patients. BLX implants can placed with immediate function on single-tooth and multi-unit restorations when good primary stability is achieved and with appropriate occlusal loading, to restore chewing function. The prosthetic restorations used are connected to the implants through the corresponding abutment components.

Straumann BLX Implant System consists of fully tapered endosseous dental implants; manufactured from Titanium-13 Zirconium alloy (Roxolid); finished with SLA or SLActive surface. Implants feature TorcFit conical internal connection with Torx-style engagement. Used by dental clinicians in clinical settings for oral rehabilitation; implants surgically placed in upper or lower jaw; prosthetic restorations connected via abutments to restore chewing function. Subject devices include 6mm length implants with 3.75mm and 4.0mm diameters. System provides functional and esthetic benefits for patients requiring tooth replacement. Device is MR Conditional.

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.)(2) *Classification.* Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use; (ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads; (iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system; (iv) The device must be demonstrated to be biocompatible; (v) Sterility testing must demonstrate the sterility of the device; (vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment; (vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians; (viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and (ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.

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.

## Performance Testing
#### Bench Testing
Dynamic fatigue testing 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" and demonstrated the subject BLX Implants System is equivalent to the predicate and reference devices. The test was conducted in saline (2 Hz and 37°C) at 2 million cycles covering permanent restoration of the implant without failure.
Insertion tests were performed for the subject devices and it could be proven that there is an adequate insertion torque in different bone classes when the implant is inserted according to the surgical procedure.
Surface area comparison and pull-out testing were leveraged from K200586 as the endosseous surface area of the subject implants is identical to the referenced implants from K200586.
#### Biocompatibility Testing
Biological assessment has been performed according to ISO 10993-1:2009 "Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process" and 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" for each of the subject devices.
The subject device materials are identical to the predicate and reference device materials, therefore, no new issues regarding biocompatibility were raised.
#### Sterilization Validation and Packaqing
The sterilization process for the subject BLX Implant System as recommended in the labeling was validated to a sterility assurance level (SAL) of 10-6 in accordance with ISO 11137-1:2006, Sterilization of health care products - Radiation - Part 1: Requirements for development, validation and routine control of a sterilization process for medical devices, 2006-04-05. The validation method used was the over kill bioburden method in accordance with ISO 11137-

Straumann® BLX Implant System
510(k) Summary
2:2013, Sterilization of health care products – Radiation – Part 2: Establishing the sterilization dose. The packaging of the subject BLX Implant System is equivalent to the packaging of the predicate and reference device. The shelf life for devices provided sterile is 5 years. The devices will not be marketed as non-pyrogenic. Pyrogenicity information provided is based on FDA Guidance on "Submission and Review of Sterility Information in Premarket Notification (510(k)) Submission for Devices Labeled as Sterile, issued on 21 January 2016." The method used to determine the device meets pyrogen limit specifications is LAL Endotoxin Analysis with testing limit of 20 EU/device, based on a blood contacting and implanted device.
# Conclusion
The documentation submitted in this premarket notification demonstrates the subject Straumann BLX Implant System is substantially equivalent to the primary predicate and reference devices.
