About Us

Functionality, design & aesthetics are our drivers for delivering uniqueness to our customers. Making their daily work more easier and successful is our mission.



Chewies or aligner fitters are small cylinders which can be used in orthodontic therapy with clear aligners/invisible braces. It can be used with any invisible braces brand. Croatian chewies are manufactured in European Union, in Croatia. They are made of medical material that meets:

  • EU Food Contact Materials (FCM) standards
  • USA Food Contact Materials (FCM) standards

so can be used safely in the mouth.

Chewies look like a small rollers. Clear aligner user bite chewies while the aligners are on the teeth.


Main and only advantage of using chewies with clear aligners is to help to properly seat aligners on their teeth. Clear aligner user bite fitter while aligners are on the teeth which push aligners close as possible against the teeth. As aligners are on right position this could lead to several advantages.

  • Reduces possibility of creating gaps between aligners and teeth
  • As aligners are closer to the teeth will lead to more precise work of forces involved in tooth movement

It’s recommended that chewies are used each time when placing aligners on the teeth. This makes it easier and more precise to position the aligners on the intended place.


Chewie is used in a way that user takes it with his fingers, puts it in his mouth and bites it while aligners are on his teeth. Before and after using it, user should wash chewie and store it. This should be repeated each time when chewie is used.

For safety and hygienic reasons it is recommended that chewies are changed once a week or together with change of aligners. When user changes his aligners, e.g. when changing aligner number 4 with aligner number 5, user should throw chewie and take new chewie together with new set of aligners (1 aligner = 1 fitter).

Due to COVID-19 and other possible virus and bacterial infections we strongly recommend that you follow our instructions of regular changing chewies.

You cannot make 15 years of experience “in no time”

With more than 60.000 of successfully inserted implants and over 15 years’ experience place Z-Systems as global leader in ceramic implants and have brought significant advances in manufacturing, quality and know-how. Z-Systems 5th generation of implants with >98% Survival Rate brings Z-Systems in rank with leading titanium implants manufacturer.

The first ever ceramic implants with CE and FDA certification

Z-Systems obtained first CE certification for one-piece ceramic implants in 2004. These are manufactured with they safe Zirkolith® process. In 2007. Z-Systems were the first ceramic implant manufacturer to meet the requirements to obtain FDA certification. Four years later, they continued this success with they Z5c two-piece ceramic implant. The Z5m(t) conical ceramic implant with active threads was certified by the FDA in 2015. and successfully introduced around the world. Z-Systems is the first and only manufacturer of a bone-level implant made of ceramic with platform switching.

Use of laser for structuring the implant surface – SLM (Surface Laser Modified)

From 2011 Z-Systems is using SLM – Surface Laser Modified process for they 5th generation of implants leading to improve osseointegration. Ceramic implants surfaces shouldn‘t be acid etched but laser modified. Acid etching might lead to weakening of the material and fractures.

Ceramic implants advantages

More sustainable/Less possibility of Peri-Implantitis

Less plaque accretion than on titanium. This reduces the risk of peri-implantitis as well as cardiovascular diseases and strokes.1

More natural

Bones and gums integrate better with zirconium oxide ceramics.2


Z-SYSTEMS implants are metal-free, biocompatible, conduct neither heat nor electrical energy, and cause no irritation to the immune system.3

More aesthetic than titanium implants

Thanks to the white material, no gray shadows are visible even with thin or receding gums which can occur in described cases.4

Z-Systems ceramic implants advantages

Osseointegration achieved with SLM process (Surface Laser Modified)

The patented surface is sand-blasted and laser-modified with an SLM® process. This trusted process has been used since 2011. This not only roughens the sides of the threads, it also achieves the optimal degree of micro and macro roughness (2–3 μ).

Abutment customization

Z-Systems abutments come in two different angles. Straight and angled 150. What is innovative from Z-Systems abutments that they can be customized and that dentist can achieve maximum angle of 350. Additionally, reduction of the abutment height by up to 2 mm is possible.

Intraoral grinding like natural tooth

Intraoral grinding of Z-Systems implants is possible like grinding of natural tooth.
