Zygoma implants: solution for severe bone deficiency.

Zygoma implants are a specialised type of long dental implant used in patients with significant bone deficiency in the upper jaw. Unlike conventional implants, which are placed into the jawbone, Zygoma implants are anchored into the zygomatic bone, which often retains sufficient stability even in patients with substantial upper jaw bone loss.

This treatment is indicated when conventional implants are not possible due to insufficient bone volume, or when a conventional solution would require extensive bone augmentation procedures. Zygoma implants can provide a fixed implant-supported prosthetic solution even for patients who have worn a removable denture for many years or who have experienced significant bone loss.

Zygoma therapy requires detailed planning, 3D diagnostics, and expertise in complex implantology. For this reason, it is not planned routinely, but only following a precise assessment of anatomy, sinus morphology, zygomatic bone quality, and the feasibility of stable prosthetic rehabilitation.

Zygoma implants may be the optimal solution for patients who do not have sufficient bone in the upper jaw for conventional implants. This frequently occurs following prolonged denture wear, long-term tooth loss, periodontal disease, previously failed treatments, or natural bone resorption following tooth extraction.

This treatment is of particular importance for patients who have been told they are not candidates for implants, or that they must first undergo extensive bone augmentation. In certain cases, Zygoma implants can reduce the need for comprehensive augmentation procedures and provide a faster pathway to fixed teeth.

The most common candidates are patients with complete or near-complete edentulism of the upper jaw, patients with an unstable denture, patients with significant bone loss, and patients seeking a fixed solution when conventional implants are not possible.

The price of Zygoma implants depends on the complexity of the case. As this is a more advanced treatment than conventional implant placement, the price should not be determined without a clinical examination and 3D diagnostics. It is essential to evaluate the remaining bone volume, sinus condition, position of anatomical structures, the need for tooth extractions, and the type of final prosthetic restoration.

Zygoma implants are generally more costly than conventional implants, as they require specialised planning, an experienced implantologist, a more complex surgical procedure, and an individualised prosthetic solution. In some cases, Zygoma implants are used exclusively, while in others they are combined with conventional implants.

The final cost of treatment also depends on whether temporary prosthetic work is planned, a final zirconia restoration, the All-on-4 concept with Zygoma implants, or another type of fixed prosthetic solution. For this reason, following the examination, the patient receives an individualised treatment proposal along with a clear explanation of what the treatment entails.

The process begins with a thorough clinical examination and 3D CBCT diagnostics. The implantologist analyses the upper jaw, the volume of remaining bone, the position of the sinuses, the zygomatic bone, and the feasibility of stable implant placement. Without 3D diagnostics, it is not possible to plan Zygoma therapy with confidence.

Following diagnostics, an individual treatment plan is developed. The plan includes the number of implants, the possibility of combining conventional and Zygoma implants, the type of temporary restoration, the final prosthetic work, and the course of treatment. In more complex cases, it is particularly important to plan the positioning of the implants and the future prosthetic restoration as a single, unified concept.

The surgical procedure is performed according to the treatment plan. Following implant placement, and depending on the stability and condition of the patient, temporary prosthetic work may be planned. The final restoration is fabricated after the healing and stabilisation phase, with adjustments made to the bite, aesthetics, and function.

For patients with insufficient bone volume, various treatment options are available. In some cases, bone augmentation or a sinus lift procedure can be performed, followed by conventional implant placement after healing. In cases of more significant bone loss, this approach can be lengthy, demanding, and may not always be the most appropriate choice.

Zygoma implants can be an alternative when conventional bone augmentation is not the ideal option, or when the patient wishes to avoid a multi-stage process with lengthy waiting periods. Instead of creating additional jawbone, Zygoma implants utilise the zygomatic bone as a stable anchor for the implant-supported solution.

The most suitable solution cannot be determined without a clinical examination. For some patients, bone augmentation is the better choice; for others, Zygoma implants; and for others still, a combination of therapies. Individual diagnostics are therefore essential.

The primary goal of Zygoma therapy is not merely the placement of implants, but the creation of a stable foundation for fixed teeth. Patients with insufficient bone volume often wear a removable denture for years or believe that a fixed solution is simply not available to them. Zygoma implants can open the possibility of fixed prosthetic restoration even in such cases.

Fixed teeth on implants provide greater stability, more confident chewing, clearer speech, and an enhanced sense of security in everyday life. With properly planned treatment, the patient can receive a solution that is significantly more stable than a conventional removable denture.

It is important to emphasise that Zygoma therapy is always planned with a prosthetically driven approach. This means that the implants are not an end in themselves, but are planned in accordance with the future position of the teeth, smile aesthetics, bite, and function.

Complete edentulism of the upper jaw is frequently accompanied by pronounced bone loss. Patients who have been without teeth for an extended period, or who have worn a removable denture for many years, may lose so much bone that conventional implants are no longer straightforwardly feasible.

Zygoma implants can offer a solution for precisely these patients. Rather than abandoning treatment due to insufficient bone volume, it is possible to assess whether conditions exist for anchoring implants into the zygomatic bone. This opens the possibility of fixed teeth even in highly complex cases.

In cases of complete edentulism, it is essential to assess the entire jaw, the bite, the condition of the soft tissues, and the patient's expectations. Treatment is planned not solely for aesthetic reasons, but also with regard to function, stability, and long-term maintenance.

Long-term denture wear frequently leads to bone loss, particularly in the upper jaw. The denture may become increasingly unstable, and the patient may experience difficulties with chewing, speech, soreness, and a persistent sense of insecurity.

For patients who wear a denture and do not have sufficient bone for conventional implants, Zygoma implants may represent an important therapeutic option. The goal is to replace an unstable removable denture with a fixed implant-supported restoration, provided the necessary anatomical and medical conditions are present.

Patients frequently come to us asking whether it is ever possible for them to have fixed teeth again. This is precisely why 3D diagnostics are essential — they reveal whether Zygoma therapy or another implantological solution can be planned.

In certain patients, Zygoma implants can be combined with the All-on-4 concept or with other fixed implantological solutions. This means that some implants can be anchored in the zygomatic bone while others are placed in the remaining jawbone, depending on the patient's anatomy.

This combination can be beneficial for patients who lack sufficient bone in the posterior region of the upper jaw but retain a certain amount of bone in the anterior region. Treatment is always planned individually to ensure that the final prosthetic restoration has a stable and reliable foundation.

It is important to understand that Zygoma is not a 'one-size-fits-all procedure', but rather part of advanced implantological planning. Some patients receive a single Zygoma implant, others two or more, while in some cases Zygoma implants are combined with conventional implants.

The greatest advantage of Zygoma implants is the possibility of a fixed solution for patients with significant bone deficiency. These are often patients who have worn a denture for many years, or who have already been informed that they are not candidates for conventional implants.

Zygoma implants can reduce the need for extensive bone augmentation procedures, shorten the treatment pathway for certain patients, and provide a stable foundation for fixed prosthetic restorations. For the patient, this can mean improved chewing function, greater confidence in speech, and an enhanced quality of life.

A further significant advantage is that the treatment is planned individually and can be combined with other implantological solutions. This allows for a more flexible approach to complex cases.

Zygoma implants are an advanced solution, but they are not suitable for every patient. The therapy requires thorough diagnostics, careful planning, and experience in complex implantology. As with any surgical procedure, there are risks and limitations that must be explained prior to commencing treatment.

Not all patients are candidates for Zygoma implants. It is important to evaluate the patient's general health, sinus condition, upper jaw anatomy, zygomatic bone, oral hygiene, and expectations. In certain patients, a different type of treatment may be the more appropriate choice.

A good treatment plan always includes a clear explanation of the options, limitations, costs, phases of the procedure, and maintenance requirements upon completion of therapy.

The duration of therapy depends on the complexity of the case, the number of implants, the need for tooth extractions, the possibility of temporary restorations, and the type of final prosthetic solution. For some patients, therapy can be planned more quickly, while for others it requires multiple stages.

The process typically involves an examination, CBCT diagnostics, planning, the surgical phase, a temporary restoration where possible, a healing phase, and the fabrication of the final restoration. In Zygoma therapy, it is especially important not to rush the stages that are critical to safety and long-term outcomes.

From the very outset, the patient should receive a general outline of the plan: how many appointments are expected, what is performed at each stage, and when the temporary or final prosthetic restoration can be anticipated.

Zygoma implants and the prosthetic work supported by them require regular hygiene maintenance and check-ups. Although this is a fixed solution, the area around the implants and prosthetic restoration must be kept clean in order to minimise the risk of inflammation and complications.

The patient should use the recommended cleaning aids, attend regular check-ups, and undergo professional cleanings. Particular attention is given to the bite, the stability of the prosthetic work, and the health of the soft tissues around the implants.

The long-term success of Zygoma therapy depends on proper planning, high-quality execution, prosthetic precision, and regular maintenance.

The patient is assessed and Zygoma therapy is managed by an implantology surgeon Dr. Zdravko Grnja, DMDZygoma is planned in a prosthetically guided manner and exclusively following 3D CBCT diagnostics — analysis of the anatomy of the upper jaw, sinuses, and zygomatic bone.

Evaluation process: CBCT → anatomy analysis → assessment of standard implants → augmentation assessment → Zygoma therapy assessment → individualised treatment plan. We do not position Zygoma as the automatically best therapy — in cases of moderate bone loss, augmentation or All-on-4 / All-on-6.

The definitive restoration is crafted in our in-house CAD/CAM laboratory (5-axis milling). For complex reconstructions, please see case studies.
