Technical Questions

T1     "​Which information do you need to produce a root analogue dental implant for me?"

A normal dental X-ray, preferably a panoramic X-ray and a single-tooth X-ray. From this we can decide if this procedure can be done in general.

To make a final decision, we definitely need a good quality CT or CBCT scan. In some cases we need a digital scan from the upper and lower jaw, and occlusion.

T2     ​"Can you produce the implant out of any CT/CBCT scan?"

Unfortunately, it cannot be done in every case, as there might be severe artifacts by root fillings, ceramic and metal crowns and implants. But don’t worry, we are still able to produce an implant in the old traditional way from the extracted tooth or an impression of the tooth socket. ? It must be a full arch scan of the respective jaw, not only a partial scan

T3     "​Do I need to visit before the implant treatment?

No. We can do everything from good quality digital scans of upper and lower jaw. In general everything can be done in single visit, from extraction, to implant placement, to a provisional. It’s advisable to have an open-minded dental professional with good communication skills, for follow-up treatments, if it’s not possible to come for follow-up consultations. Anyway, remember that Vienna is always a worthwhile visit.

T4    "​What can I do to get a better CT/CBCT scan?"

CT scanners are a mature, established technology.

T5    "Is any CBCT machine good enough?"

No, only a recent one, because it’s a new technology with big advancements over the last few years. In general, the most recent is the best.

T6    "​How can I send you a CT/CBCT scan?"

The only way is a link to Dropbox, WeTransfer, Google Drive, or some other cloud storage.

T7    "Which ceramic do you use?"

Medical grade zirconia has been used for over 20 years as an implant material on humans, and is very well known to be highly biocompatible. All studies so far indicate that it osseointegrates as well as, if not better, than titanium.

T8    ​"What are the dark marks on newly fitted implants (visible in the Case Gallery photographs)?"

During the seating of the implant, the contact between the metal driver and the much-harder zirconia sometimes leaves marks (since zirconia is almost as hard as diamond). These marks can be removed at any time by a dental burring tool immediately after implant placement or during the preparation of the crown stump.

T9    "Is immediate loading possible?"

As it is a single piece implant, there is always a reduced load on the crown stump. Further reduced loading is possible on molars and premolars; the patient is instructed to avoid hard food and to chew on the other side for 12 weeks. For esthetic reasons, or if the patient is not compliant, a provisional or protective splint may be advisable.

T10   ​"Can zirconia implants break?"

Of course anything can break, what matters is whether it is likely to or not.

Why would a tooth milled from zirconia break, since there are no fatigue fractures?

If anything ever breaks, it is the crown and not the implant.

It is highly implausible that a BioImplant™ will ever break due to its profile of a natural tooth (generally, a non-uniform oval), as this natural geometry is much stronger than the original tooth, as well as any screw type implant.

T11   ​"When is it possible to make a final crown?"

The final crown can be done regularly after 8-12 weeks, depending on your personal situation.

T12    "CT/CBCT requirements"

A dental CT scan is a mature technology from the 1970s, and so the present machines are all of very good quality.

In contrast, CBCT scanners for private practice are a new technology, starting in the early 2000s, which has improved significantly since then. We need the latest and best technology for segmentation. Therefore it would be best to have scans from the latest generation of scanner.

Slice thickness between 0.3 – 0.5mm will be fine.

For evaluation, you may send a CT scan via DropBox, to:

T13    "Can a BioImplant be removed again?"

Compared to screw implants, removing a BioImplant is much easier.

But in general, there is no reason to remove a BioImplant, as peri-implantitis is extremely rare.

A fracture can only occur from severe trauma, not from chewing itself, as can happen with titanium screws (fatigue fracture).

Screw implants, on the other hand, often show peri-implantitis, which cannot be controlled in the long term due to the screw threads.
