Zygomatic implantation is a dental implant technique used for patients with extreme maxillary atrophy, as well as for those with severe maxillofacial trauma or oncology patients.
If you’re exploring this method, chances are you’re facing similar challenges.
We recommend reading this article through to the end before making your decision.
The original technique was introduced by P.I. Brånemark in 1989 for the treatment of patients with post-resection defects of the upper jaw.
In 1993, his student C. Aparicio described the use of a transzygomatic implant in a patient with severe atrophy of the upper alveolar ridge.

Since then, this type of dental implant has been used for patients with maxillary atrophy as an alternative to bone grafting in the upper alveolar ridge.
As this historical overview shows, the method has over 30 years of clinical use and is now considered the “gold standard” in the rehabilitation of patients with advanced upper jaw atrophy.

To summarize, the success of bone grafting decreases in direct proportion to the length of time a patient has been without teeth and wearing removable prostheses.
In simple terms, in the bone grafting zone there are simply no bone cells left capable of transforming the grafted tissue into the patient’s own bone.
The arrows indicate thinning of the mucosal lining and periosteum, and maxillary atrophy.

WHY DO WE USE TRANSZYGOMATIC IMPLANTATION IN PATIENTS WITH COMPLETE MAXILLARY ATROPHY INSTEAD OF BONE GRAFTING?
All of the above confirms the rationale for choosing angular dental implantation methods in patients with complete tooth loss and severe maxillary atrophy.
These methods involve anchoring implants in zones unaffected by atrophy, such as the zygomatic bones, nasofrontal buttress, shell crest, and pterygoid processes of the sphenoid bone.
The advantages of angular implantation (zygomatic, transnasal, pterygoid) lie in the fact that due to the length of the implants and their fixation in areas unaffected by atrophy (zygomatic bones, etc.), implants can be stabilized immediately during surgery.
This allows for the production of non-removable temporary prostheses that can load the implants and enable chewing and the intake of soft food within the first days after the operation.

The risk of complications and rejection of zygomatic implants does not exceed 5%.
This percentage is comparable to the complication rate of conventional implants.
By contrast, the risk of complications during sinus lift surgery under similar conditions is about 15%.
Limitations include the need for careful preparation and the restricted use of this method in patients with chronic sinus diseases.

The effectiveness of this approach in the rehabilitation of patients with advanced bone atrophy is demonstrated in the “Treatment Stories” section.
This is due to the fact that the loss of functional load after tooth loss leads to changes in the structure of the jaw bones through a decrease in bone density.
In cases of prolonged toothlessness, chewing load diminishes, resulting in regional osteoporosis.
In this condition, the maxillary bone is unable to respond adequately to functional loading and loses its ability to structurally remodel.
This condition is the result of several factors, with the most significant being long-term edentulism (2 years or more) and wearing removable dentures.
Numerous studies confirm the negative impact of removable prostheses on the periosteum and jaw bone due to impaired blood circulation in the prosthetic bed and almost complete degradation of the osteogenic layer of the periosteum.
This directly affects the success of bone grafting procedures.
