Dr. Carmichael is an award-winning researcher, lecturer and clinician. “I’m confident in the science behind this development, and early clinical results are promising” he says.
What characteristics of these surfaces most interested you?
The surface chemistry is really interesting: surface roughness has been a key focus for many years, so for me to get more insights into how chemical properties can be modified for tissue integration is great.
I also like the fact that they have been designed together for integration at all levels, so not just osseointegration but also for soft tissue integration. Having read the research, I appreciate how characteristics have been designed to benefit my patients in this respect: it gives me confidence in achieving tissue integration, as well as maintaining soft tissue height.2
The Protective Layer also keeps the surfaces pristine, which is certainly something that I appreciate and that I believe can benefit my patients.
Do you have confidence in the long-term clinical outcomes of implant treatment conducted with Xeal and TiUltra?
I have a lot of confidence in the system to the point that I’m only using the Xeal Multi-unit Abutments. I’m blessed at the Brånemark Centre to still be seeing some of Australia’s first implant patients from the early 1980s, so witnessing long-term success is especially important to me. These surfaces are still in their early days, but if I had any reservations or concerns at all, I certainly wouldn’t have switched over. I’m confident in the science behind this development, and early clinical results are promising. We’ve previously seen in other studies that if we can achieve good initial implant outcomes, we can then promote long-term success, and so Xeal and TiUltra surfaces are on the right track from what I can see.
Have you received any particular questions regarding Xeal or TiUltra from trainees?
Probably the most frequently asked question I have encountered is if the golden hue is sprayed or coated on. It then gives clinicians a lot of confidence when I tell them that it’s the anodization process that has allowed this warm, golden color to form, rather than any additional material. It’s a happy consequence of using this particular technology to tailor the surface at soft tissue level.
What do you think of the golden hue of Xeal and of the TiUltra collar?
I definitely see the benefits of this, particularly for patients with thin tissue biotypes who might be more susceptible to dark shadows associated with grey machined implant and abutment surfaces. The golden hue seems to help the implant appearance in these areas, to make it more natural looking.
What three words would you use to describe Xeal and TiUltra surfaces?
Science, stability, success.
