Intended Use

Straumann® dental implants and abutments are intended for oral implantation to provide a support structure for connected prosthetic devices.

Device Story

Straumann® BLC and TLC implants are endosseous dental implants designed for oral rehabilitation. These solid screw implants are manufactured from Titanium-13 Zirconium alloy (Roxolid®) with a large-grit sandblasted and acid-etched surface (SLActive®). The implants are surgically placed into the jawbone by a dental clinician to serve as a support structure for prosthetic restorations, including single crowns, bridges, and dentures. The device functions by integrating with the bone to restore chewing function. This line extension introduces additional diameter and length configurations to the existing portfolio. The implants are provided sterile and are intended for use in a clinical setting. The output is a stable foundation for dental prosthetics, which directly benefits the patient by restoring oral function and aesthetics.

Clinical Evidence

No clinical data provided. Evidence is based on bench testing, including sterilization validation (ISO 11137-1/2), biocompatibility assessment (ISO 10993-1), and mechanical insertion testing. Biocompatibility was confirmed across accelerated aging intervals (T0, T3, T5 years).

Technological Characteristics

Material: Titanium-13 Zirconium alloy (Roxolid®). Surface: Hydrophilic SLActive® (sand-blasted, large grit, acid-etched). Connection: TorcFit (conical). Sterilization: Gamma or X-ray irradiation (SAL 10^-6). Dimensions: Various diameters (5.5mm, 6.5mm) and lengths (8mm-16mm). MR Conditional per K180540.

Indications for Use

Indicated for functional and esthetic oral rehabilitation of upper or lower jaw in edentulous or partially edentulous patients. Suitable for immediate, early, or late implantation following tooth extraction or loss. Can be placed with immediate function for single or multiple-tooth restorations when primary stability is achieved and appropriate occlusal loading is applied.

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.

Straumann® dental implants are solid screw implants with a bone anchorage surface that is large-grit sandblasted and acid-etched. In addition, SLActive® is in a chemically activated state, which is preserved by storage in a saline solution (NaCl). Straumann® dental implants can be used following the extraction or loss of natural teeth to restore chewing function. The prosthetic restorations supported are single crowns, bridges and partial or full dentures, which are connected to the implants using the corresponding abutments. The purpose of this premarket notification is to extend the BLC and TLC Implants portfolio by including new sizes of implants, more specifically: ### BLC implants: - L 16 mm for diameter Ø 6.5 mm, presented with WB (Wide Base) prosthetic platform. ### TLC implants: - L 14 mm and L 16 mm for diameter Ø 5.5 mm, with both implant neck options Standard (2.8 mm height) and Standard Plus (1.8 mm height) - L 8 mm and L 10 mm for diameter Ø 6.5 mm and implant neck Standard (2.8 mm height) - L 12 mm to L 16 mm for diameter Ø 6.5 mm, with both implant neck options Standard (2.8 mm height) and Standard Plus (1.8 mm height) and presented with WT (Wide TorcFit) prosthetic platform. The submission also introduces a new sterilization method using X-ray irradiation which was validated on worst-case test articles representative of the BLC and TLC implant systems.

The sterilization process for the subject devices as recommended in the labeling was validated to a sterility assurance level (SAL) of 10° 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 (or VDmax25) method in accordance with ISO 11137- 2:2013, "Sterilization of health care products – Radiation – Part 2: Establishing the sterilization dose". There are no changes to the gamma irradiation sterilization procedures or processes from those of the Straumann primary predicate devices (K230108), the subject devices do not represent a higher challenge to the sterilization process in comparison to the validated worst-case product and validated gamma irradiation sterilization process. In addition, a validation of the X-ray irradiation as a new sterilization method was conducted. The validation method used was the VDma25. A sterility assurance level (SAL) of 10 ° was validated in compliance 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 and ISO 11137-2:2013, Sterilization of health care products – Radiation – Part 2: Establishing the sterilization dose. The packaging of the subject device is equivalent to the packaging of the primary predicate and reference device. The shelf life for devices provided sterile is 5 years. The devices will not be marketed as non-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. {10}------------------------------------------------ # Traditional 510(k) Submission - K234049 Straumann® BLC and TLC Implants - Line extension ### Biocompatibility Testing Biological assessment has been performed according to ISO 10993-1 "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 devices are equivalent in material, surface, manufacturing process, packaging materials, sterilization by gamma irradiation, body contact duration compared to the reference device K230108. Sterilization by X-ray irradiation was validated and may be used as an alternative sterilization method instead of gamma irradiation. The impact on the biological safety was evaluated and the needed biocompatibility testing was determined according to the ISO 10993-1:2018 standard. The results of the conducted tests have demonstrated that the assessed devices do not show any reactions with X-ray sterilization that could have a biological effect on the patient at T0 (no aging), T3 (3 years accelerated aging) and T5 (5 years accelerated aging for long-term effect). Thus, the subject devices are considered biologically safe for their intended use according to ISO 10993-1 and FDA's guidance document of ISO 10993-1. ### Electromagnetic Compatibility There are no significant changes to the materials and dimensions from the currently marketed predicate devices. Therefore, no new issues of electromagnetic compatibility are raised for the subject devices and they can be considered MR Conditional. The subject implants have obtained the status of MR Conditional per K180540. The MR Conditional tests were conducted according to FDA's Guidance "Testing and Labeling Medical Devices for Safety in Magnetic Resonance (MR) Environment". ### Performance Testing - Bench Insertion tests were performed for the subject implants 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. {11}------------------------------------------------ # Traditional 510(k) Submission - K234049 Straumann® BLC and TLC Implants - Line extension The subject device surface treatments are identical to the surface treatments of the primary predicate and reference devices. The SLActive® surface treatment is a sand-blasted, large grit, acid etched, chemically active and hydrophilic surface is routinely tested by roughness measurement or scanning electron microscopy. ### Conclusion The documentation submitted in this premarket notification demonstrates the subject devices are substantially equivalent to the primary predicate and reference devices.
