Is there (a test for) titanium tolerability?

There are more and more people who cannot tolerate titanium oxide, due to its broad use as a pigment. This incompatibility may be confirmed in an independent laboratory using a titanium stimulation tests; for example at IMD in Berlin for € 80-130.

Is there a step-by-step manual for Z-SYSTEMS implants? Does Z-Systems have a technical advisory board?


please see this PDF if you have our white surgical tray with the drill stops.

please see this PDF if you have our green surgical tray.

Is there a Surgical & Restorative Protocol for Z5c only?

Yes, one of our dentists, Dr. Ted Fields from Dallas, Texas wrote a Protocol for Z5: PDF

The titanium stimulation test (TST) is not reliable ...

In case of defective implementation, the complex process could have false positive and false negative results. This is due to the expensive work for each of the antigens to be tested. The procedure is accredited in adherence to DIN 15189 at several university hospitals and specialized institutes. If the laboratory carrying out the tests has insufficient experience, erroneous results can be expected.

Is zirconium oxide immunologically safe?

In laboratory blood studies, no adverse reaction could be detected with zirconium oxide . Thus, all-ceramic zirconium oxide implants are considered to be immunologically safe.

Is the cement immunologically safe?

The cement is not in contact with the body, because it is shielded by the crown . Thus, the cement is harmless.

Is zirconium really metal-free?

Yes, zirconium oxide ceramic is the product of a chemical reaction of metallic zirconium and gaseous oxygen. This product has no properties of its raw materials. This is done exactly like saline, which is made of the extremely hazardous metals sodium and highly toxic chlorine. gas.

Is zirconium oxide radioactive?

We have compiled all the information for you.

See TIB radioactivity as PDF

Do zirconium oxide implants break?

There are large differences in the material used and the manufacturing process. in ceramic implants. At zsystems, with its patented manufacturing process, Zirkolith® demonstrates a higher breaking resistance than titanium implants. A good occlusion design is decisive for long-term success.

Are bone-integrating zirconium oxide implants as good as titanium implants?

Yes , zsystems zirconium oxide with its patented SLM® surface exhibit optimal roughness and integrate into the bone exactly as well as titanium implants.

Can you provide zirconium oxide implants immediately?

Yes , sufficient primary stability and an appropriate design allow an immediate supply - no immediate loading. All macromobility must be avoided; micromobility supports the bone healing process. See TIB immediate supply as PDF

Can I (surgeon/remitter) share the work with zirconium oxide implants?

Yes, this is quite simple with the new two-piece Zirkolith® implants. And with appropriate tuning, the one-piece implant can also be worked on by two people.

How does the healing time work in comparison to TiUnite/SLA?

The bone healing process takes 6-8 weeks in the human body. Experienced users report that they perform a successful treatment after 6-8 weeks with appropriate bone quality and healing process.

Titanium implants also have a ceramic surface ...

The surface of metallic titanium is passivated on contact with the air; it forms a thin layer of titanium oxide, but it is not stable. The formation of galvanic elements with other metals in the oral cavity is thus not avoided. zirconium oxide is an all-ceramic material in which reactions no longer occur.

Are there any long-term studies (over 5 years) on material fatigue with zirconium oxide ceramics?

Material fatigue is tested in extensive, standardized tests according to the DIN ISO standard. The zirconium oxide used by zsystems is hipped and its fatigue is only have as great as unhipped zirconium oxide.

The prosthetic is very awkward ...

The one-piece implant prosthetic is just like a natural tooth. And for two-piece implants, prosthetic components such as healing caps, gingiva formers and various abutments are available.

My patients do not want any protective measures ...

For patients who do not accept protective measures, the two-piece ceramic implant Zirkolith® is protected by the mucous membrane and can be exposed to chewing forces. And the one-piece implant can dispensed a measure of protection if there is good bone quality and high insertion torque.

Do you have a screw-in solution?

Yes, we do have a screw retained solution: Z5s. Right now, implants with a diameter of 5mm and lengths of 8,10 and 12 mm are available. We are constantly working on more sizes and a bigger abutment selection.

Are there any studies when protection measures were not needed?

No studies but case reports showing that if there is sufficient primary stability, protection measures can be waived, and the implant can be supplied immediately.

Can the primary stability measure (such as SDS and DP)?

We recommend measuring the primary stability using PERIOTEST.

How stable is the connection with Z5c (deduction/rotation)?

Depending on the diameter, the stability in the range of 300 to 650 N (according to DIN ISO 14801).

How can i prepare Z5c?

After cementing the abutment, this can be prepared in situ. You can find detailed instructions in the manual.

What is the situation with bone loss?

Zirkolith® zirconium oxide is characterized by excellent tissue compatibility. The crestal bone remains very stable to the last thread. In some cases, further bone growth has been observed on the Zirkolith ceramics.

What do you recommend for rotation backup of single crowns?

We recommend the preparation of the stage like a natural tooth.

Why is there no individual abutments?

The potential of individual abutments can only be exploited in implants which are placed at bone level. For two-piece soft tissue-level implants, the transmucosal part can be formed by the upper implant body.

How rough is the SLM surface compared to standard titanium?

The patented SLM® surface of the Zirkolith® ceramic implants has an optimal roughness comparable to that of standard titanium implants.

Why is there no laboratory analogs and impression posts with Z5c?

Z5c was developed in order to make the prosthetic design even easier, especially for angular abutments and bridges. Since the final restoration is usually a ceramic bridge, unnecessary sources of error would occur with laboratory analogs and impression posts. A zirconium oxide bridge is not separable cannot be soldered or lasered as with a metal bridge. We have therefore avoided the laboratory analogs to improve quality.

There are not enough clinical data ...

Yes, there are fewer clinical data than for the 2-3 international premium titanium implants. But the clinical documentation of Zirkolith® ceramic implants is comparable with that of other titanium implant systems. Upon request, we will gladly send you a literature compilation.

I do not need it, I have 100 % success with titanium ...

100 % is very rare and you can achieve the same success with Zirkolith® ceramic implants you can with titanium implants. In any case, with better mucosal membrane behavior even after years, and no shadows or colorations in the case of gingival recession. We have people who are working exclusively with ceramic implants who have seen more patients, because the colleagues do not offer this option in their region.

Are there reference lists with users or instructors?

We would be glad to give you the names of speakers and users by telephone.

I have no patients who want ceramic implants...

Good consultation also includes information about ceramic implants and a factually correct discussion. How do they want to justify that your patients have not been advised of ceramic implants when the patient has an intolerance and did not know that they had it.

Is there a recommended abutment placement protocol?

Yes, please find our abutment placement protocol here.

Is there an Overview for Prosthetics for Z-SYSTEMS implants?

yes, please see this PDF.

Is there a Z-Systems Referral Program?

Yes, we do have a Z-Systems Referral Program.
