ZIC ® - Zygomatic Implants Clinic ®


In the 1990s, P.I. Bränemark (Sweden) started using the bone that forms the cheek as a anchoring point for (zygomatic) dental implants. In the year 2003-2004, documentation and data were published showing success rates with Zygomatic Implants that were as good as with conventional implants.

The technique of Zygomatic Implants has been developed over the last twenty years, and, as such, those implants are not really a point of debate. They do not rely on the alveolar jaw bone anchorage, as do conventional implants, but rely solely on the zygoma achorage. Those implants are much longer (in a range from 3.5 to 5 cm) than conventional implants (0.7 to 1.5 cm).

The zygomatic bone is an excellent quality bone with sufficient bony volume in virtually all patients. In each zygoma there is enough space and volume to place one or two implants. When those implants are connected to a fixed dental bridge work they are conceived to withstand normal chewing forces.

Surgical Indications

Zygomatic implants are reserved for patients with an explicit lack of upper jaw bone in the rear areas and where bone grafting is not immediately an option. Older patients are good indications, since no bone grafts are necessary and the fitting supra-structure (i.e. teeth) can be made for immediate loading (i.e. from a practical point of view, two days after implantation, with an aesthetic pass and trial included).

With zygomatic implants patients have teeth in a couple of days, whereas if implants have to be placed into the graft approach it takes about four to eight months to finalise the extended bridge.

Most often, one zygomatic implant on each side can be combined with regular implants in the front region.

Zygomatic surgery or Bone grafting?

Bone grafting is a technique that has various limitations:

  • bone grafting from pelvic bone or the skull (first surgery under general anesthesia)
  • after first surgery no provisional removable prostheses at least for two months
  • after six months from first surgery implants insertion (second surgey) and another six months of mobile protheses
  • post-surgery disconfort is severe
  • fixed teeth only after 12 months
  • chances of surgery success between 60 and 80%.
What are the advantages of zygomatic implants?
  • the problem is solved with one single surgery
  • after 24 hours from surgery the patient receives a temporary fixed prothesis
  • high chances of success about 98%
  • limited postsurgery discomfort
  • never mobile protheses during all the treatment
  • after six months from surgery the treatment is completed with a definitive prosthesis


SUCCESS RATE 60-80% 98%

It's clear that zygomatic implants are a valid alternative to autologous bone grafts because, by comparable costs, they allow for faster treatments with higher success rate and less discomfort for the patient who gets fixed teeth after 24 hours from surgery.

The procedure

Before the operation, an extended i-cat is taken, enabling us to study the bone structures, especially the zygoma bones in a three dimensional way. Zygomatic implants are placed in one surgical procedure under endovenous sedation or general anarsthesia.

The zygomatic implant can be located inside, outside, or within the bony wall of the outer part of the upper jaw sinus.

This housing is dictated exclusively by both ends of the implant:

  • the cranial part of the implant must be housed safely within the zygomatic bone volume
  • the distal part of the implant must be housed anatomically on the crest underneath the arch form of the future crown and bridge work
  • the result must be a non-disruptive exit for your bridgework (i.e. the exit not on the palate)

Option 1 : Quad Zygoma
Four zygomatic implants are placed in the totally & extremely atrophic upper jaw (no bone for regular implants) followed by a fixed supra-structure (teeth) within a few days. An extra regular implant at the front is always welcome for reasons of stability and can prevent a lot of regret afterwards.
Option 2 : Zygoma
Two zygomatic implants are placed in the second premolar area and three to four regular implants in the anterior upper jaw. This option is also followed by a fixed supra-structure (teeth) within a few days.

Patients benefits

  • Improved appearance
  • Normal looking teeth and gums
  • Freedom to eat what you like
  • Confidence to laugh
  • Teeth that do not come out
  • No more denture sore spots
  • Long term tooth support
  • Faster healing than bone grafting
  • Low maintenance

Taking care of your oral hygiene after the implants:
Having a fixed bridge on zygomatic implants still means that you need to maintain regular daily oral hygiene. Along with brushing, most patients use a water-pick for routine cleaning around the implants and the bridge. Visits to a mouth hygienist on a regular basis are also mandatory for control and/of cleaning.

The mucosal area around the zygomatic implants must be checked for dehiscence.

A soft plastic mouthguard during the night may be advisable, certainly during the first year and certainly if you know you are clenching your teeth.
