Zygomatic Implants

Zygomatic implants are particularly long implants that are embedded in the cheekbone (medical term: zygomatic bone) when there isn’t enough bone tissue in the upper jaw for normal implants. With zygomatic implants, even seemingly-impossible situations can be solved with fixed teeth.

Zygomatic implants are significantly longer than normal dental implants and are anchored in the stable bone that makes up a part of the cheekbone — this explains their name. Therefore zygomatic implants can be used as an alternative to complex bone augmentation. Like fixed teeth, in a day this requires merely one surgical procedure.

The benefits of the zygomatic implants at a glance:

• Strong teeth within a day thanks to state-of-the-art implant technology
• No palate cover thanks to individual dentures
• No bone construction thanks to innovative surgical techniques
• Quick procedures and fewer treatment appointments
• Immediate loading is possible

What are the steps of the procedure with zygomatic implants?

Prior to the surgical procedure, we do a thorough and extensive examination to accurately assess the situation. We will first make photos, stone plaster models of your teeth and a three-dimensional X-ray (CBCT). This is necessary to accurately determine and implant placement and length.

These preparatory measures are completely painless for the patient and take only a few minutes. The actual operation is then done under sedation since the placement of zygomatic implants is more complex than normal implants. The sedation is always done by an anaesthetist. After the zygomatic implants have been placed, the implant positioning is transferred onto a stone plaster model with an impression.

Our dental technicians then construct a bridge, which can be screwed onto the new implants. Due to the very solid bone tissue of the zygomatic bone, the implants and the restoration can usually be used straight after the surgery.

Are zygomatic implants suitable for every patient?

Zygomatic implants can be used for every patient if no general medical or behavioural condition speaks against it. However, this option is only taken into consideration when there is no possibility to use regular implants. This is the case when there is too little bone tissue in the upper jaw. Zygomatic implants are also a great option for patients where it is impossible to do bone augmentation, or where the willingness to undergo such a surgical procedure is lacking. Navigated implantology: placement of implants — precise, secure, careful.

Navigated implantology means that the placement of a dental implant is already simulated on the computer in a three-dimensional patient model (3D X-ray, CBCT) before the procedure. A computer-manufactured guide template transfers the virtually planned implant position into reality and safely and accurately directs the implant to the desired position in the jawbone of the patient.

In our clinic, we use the latest and most powerful methods with respect to the navigated implantology, eg Nobel Clinician from Nobel Biocare or the SMOP®-method of the company Swissmeda. The more time a surgeon spends before the operation, in diagnosing and planning the actual surgery, the safer the procedure becomes. It is like a pilot going through the flight before take-off. Your safety is always our primary concern.

Advantages of navigated implantology:

• very precise positioning of the implants
• protection of sensitive neighbouring structures (nerves, blood vessels etc) in the treatment area
• rapid wound healing due to the minimally invasive technique (flapless surgery)
• optimum utilisation of the existing jawbone
• the aesthetic appearance of the dental restoration due to the precise positioning of the implants

Clinical procedure step-by-step

Determination of the desired form and position of the tooth. At first, the dental technician prepares the new form of the tooth on a model, known as a wax-up. The wishes of the patient can, therefore, be taken into account and visualised directly before the beginning of the treatment.

Scan template and 3D-X-ray

The wax-up is copied and the copy serves as a scan template which the patient has in his or her mouth when a 3D-X-ray (CBCT) is taken. Thus the newly designed teeth are visible in the X-ray image.

Preoperative 3D-planning

The position of the implants is planned virtually on the computer. The position of the newly designed teeth which are visible in the 3D-image serves as an orientation aid. This position is transferred into a drilling template.

Implantation

During the procedure, the surgeon transfers the virtually planned implant position by means of the drilling template. Thus the dental implants are placed exactly to the position where the new teeth will be inserted later on.

Manufacturing of dental prosthesis

After the healing phase of the dental implants, the dental restoration will be manufactured and placed according to the original planning. While the final dental restoration is manufactured, a fixed temporary may already be worn.
