SonicLinx® - The Natural Implant Interface™

SonicLinx® – The Natural Implant Interface™

SonicLinx® creates a bio-mimicking implant surface, which promotes osseointegration and reduces the risk of infections. This technology is clinically established to enhance osseointegration of dental implants.

Key Points

  • Highly hydrophilic implant surface:
    • Reduces protein denaturation and inflammatory reactions to the implant
    • Implant integration without fibrous capsule formation
  • Bio-mimicking surface:
    • Early bone growth on the implant surface will result in faster osseointegration and can allow for earlier loading
    • Increased neo-vascularization promotes healthier bone
    • Reduced risk of implant loosening even with poor bone quality
  • Human dental clinical research showed a 70% reduction of peri-implantitis
  • In vitro studies showed highly reduced bio-film adhesion
  • SonicLinx® Veterinary Kit allows for a fast and simple on-site surface preparation that permits treatment choice on a case by case basis

Technical Facts

The SonicLinx® treatment creates a nano-meter thin mono-molecular phosphonate layer which covalently binds to metal or ceramic implants. This simple, 5-step procedure can be performed by the surgeon on-site using the SonicLinx® Veterinary Kit. The surface treatment is performed in an ultrasonic bath and consists of two activation steps, a rinsing step, the SonicLinx® treatment itself, and a rinsing step again.

The SonicLinx® layer is stable in pH 1-9. Existing bone growth promoting coatings (e.g HA) often become unstable in a more acidic environment. The pH range of the SonicLinx® layer covers the different pH values occurring during osseointegration, inflammatory events, and bone remodeling.

Clinical Facts

The phosphonate layer is both hydrophilic and bio-mimicking. This promotes bone cell adhesion without formation of a sclerotic layer or capsule formation. A clinical trial with 117 human patients showed that the SonicLinx® treatment was able to reduce peri-implantitis occurrence in dental implants by 70% compared to untreated implants [1].

The highly vascularized contact surface results in a faster integration into bone and increased biocompatibility. This could potentially reduce the risk of implant loosening and therefore reduce failure rates. In a sheep study (pelvis, 2, 8 and 52 weeks), implant removal torque and bone formation were investigated quantitatively. Compared to untreated controls, after 2 weeks the SonicLinx® treated implants showed significantly higher new bone formation (+43 % New/Old bone), and higher removal torques (+32%). These results provide evidence that the critical time to osseointegration is drastically reduced by the SonicLinx® treatment. After one year, the SonicLinx® Implants still showed higher removal torques (+7%) and an increased bone-to-implant contact (+39%) compared to untreated implants [2], indicating long-term effectiveness of the SonicLinx® surface.

Furthermore, it was found that in contrast to the controls, the SonicLinx® implants showed no failure at the bone – implant interface during torque testing. This means that the interface between the implant and bone grew stronger than the bone itself enhancing long term stability further.
