Zygoma All-on-4

If you’ve been told that you’re not a good candidate for dental implants due to bone loss in the upper jaw, and that an uncomfortable denture or bone augmentation (sinus lift) are your only remaining options, you’ll be happy to hear that Zygoma All-on-4 implants are suitable for everyone!


Upper jaw bone loss is no longer an obstacle to dental implants and restoring teeth in a completely edentulous jaw.  If you’ve been told that you’re not a good candidate for dental implants due to bone loss in the upper jaw, and that an uncomfortable denture or bone augmentation (sinus lift) are your only remaining options, you’ll be happy to hear that Zygoma All-on-4 implants are suitable for everyone!

Despite the fact that dental implants are an unrivalled solution for overcoming edentulism, the main obstacle in implant placement has so far been the lack of bone to which the implant can be anchored. Due to the long-term lack of tooth roots in the area of the missing tooth, bone loss occurs, which has so far been remedied by bone augmentation – a long and sometimes unpleasant process.

A revolutionary method

​Thanks to the Zygoma All-on-4 technology, from now on every patient can leave the clinic with a beautiful smile after just one visit. This advanced method with a 100-percent success rate, as confirmed by research, allows for the treatment of edentulism in cases where complete resorption of the upper jawbone has occurred.

Zygoma implants (or zygomatic implants) are a revolutionary new type of implant that are placed in the upper jaw, with a diameter of 4.2 millimetres and length of 3.5 to 5.75 centimetres. The method was developed by Per Ingvar Brånemark, a Swedish professor and scientist who devoted much of his work to researching osseointegration – the fusion of implants with bone.

Implants are suitable for everyone.​


Suitable for everyone

This revolutionary technique eliminates the need for bone grafting or sinus lifting, since implants are anchored directly in the cheekbone, which offers enough support. Therefore, they are the best alternative to the long bone augmentation process, which was once the only option available to patients with a severely resorbed upper jawbone. In addition, implants can be placed under computer guidance, which ensures close to a 100-percent success rate for the procedure.

Are the Ortoimplant Dental SPA Clinic doctors well-experienced in implantology?

Dr Trampuš and his team of dental experts have advanced professional degrees and international certificates, as well as decades of experience in implantology.

Am I a suitable candidate for dental implants?

Whether we’re dealing with complete edentulism or a single missing tooth, implantology is the best solution. Only implants will restore the feeling of having natural teeth!

Why are Noris Medical dental implants used at Ortoimplant?

Noris Medical is a leading manufacturer of high-quality dental implants that are reliable, safe, and especially appropriate for “immediate loading” (placing implants and teeth in one day).

Who is an ideal candidate for the Zygoma All-on-4 procedure?

In a word, everyone. Jawbone atrophy is not an obstacle because the Zygoma All-on-4 procedure only requires a minimal amount of bone. If a patient has not had a tumour or systemic disease treated with drugs (bisphosphonates), the Zygoma All-on-4 procedure can always be performed.

Is it possible to carry out the procedure on both jaws on the same day?

Thanks to the all-in-one dental treatment approach and state-of-the-art technology, the procedure can easily be carried out on both jaws in one day with excellent results. The Ortoimplant team will be with you throughout the procedure, making sure that you feel comfortable and safe.

How long does it take to recover from a Zygoma All-on-4 procedure?

The recovery period following a Zygoma All-on-4 procedure varies, but it generally unfolds in the following way: painkillers are taken for two to three days, the swelling varies but returns to normal within three to five days, patients can return to work two to three days after the procedure and normal physical activity can resume at about the same time.

What is the difference between the Zygoma All-on-4 method and a denture?

A denture is a prosthetic device, which the patient removes for cleaning and maintenance. It is made of acrylic resin with ready-made teeth, and is fastened with clasps that hold the crowns. Zygoma All-on-4 is an affordable and proven alternative that uses four implants to replace a full set of teeth, thus restoring the look and function of natural teeth.

How painful is the Zygoma All-on-4 procedure?

Thanks to our unique Dental SPA approach, pain and discomfort are completely eliminated. Our patients claim that postoperative pain is negligible, compared to toothache, for example. Taking a pill that helps relieve a headache is usually sufficient. Surgical implant placement is less aggressive than tooth extraction. Implants are placed under local anaesthesia, so there is no feeling of pain, while patients who are more anxious can opt for sedation.

I was told I have a large loss of bone mass and it will take months before I can wear artificial teeth. What is the solution?

Thanks to the design and function of the Zygoma All-on-4 implants, bone augmentation is only rarely required. If there is a significant bone loss in the upper jaw, we recommend the Zygoma All-on-4 procedure, which is used for more complicated cases.

How strong will my new teeth be?

Will I be able to chew better?

You will be able to eat without fear of your teeth falling out or getting lost. The strength of the bite with implants is significantly higher than with dentures. The new bridge supports implants that are cleaned like natural teeth, with brushing and flossing.

What can I eat after surgery?

A modified diet is required for a period of two to six months, until you receive your permanent fixed teeth. In the meantime, you can eat anything that can be cut with a fork, as temporary crowns are made to last for several months.
