Zygomatic Implants

Zygomatic implants, also known as zygoma implants or zygomaticus implants, are a specialized type of dental implant designed to address the challenge of insufficient upper jawbone for traditional implants. Unlike conventional implants, which are anchored in the jawbone, zygomatic implants are anchored in the zygomatic bone, or cheekbone. This innovative approach provides a solution for patients with significant bone loss in their upper jaw.

Why Are Zygomatic Implants Needed?

Several factors can lead to inadequate bone in the upper jaw, including tooth loss, periodontal disease, or natural bone resorption. Without sufficient bone, traditional dental implants may not be stable or secure. Zygomatic implants offer a viable alternative, ensuring a strong foundation for implant-supported restorations.

What Is the Difference Between Zygomatic Implants and Conventional Dental Implants

Conventional dental implants are titanium screws inserted into the jawbone to provide an anchor for single, multiple, or full arch replacements of missing teeth. The success of conventional dental implants mainly depends on having sufficient bone to support the implant. If there is inadequate bone, bone grafts become essential, either during the same surgery or as a separate procedure.

Zygomatic implants follow the same concept as conventional dental implants but differ in key aspects. They are anchored to the zygomatic bone, or cheekbone, which is stronger and denser than the jawbone. Zygomatic implants are used to restore a full arch of missing teeth but are limited to the upper arch only. These implants are taller than conventional ones and are placed at a 45-degree angle to avoid injuring vital structures, such as the maxillary sinus. Additionally, they eliminate the need for bone grafts.

Benefits of Zygomatic Implants

• Solution for Severe Bone Loss: Zygomatic implants are ideal for patients with severe bone loss in the upper jaw, eliminating the need for extensive bone grafting procedures.
• Immediate Functionality: These implants often allow for immediate placement of a prosthesis, allowing you to eat, speak, and smile confidently soon after the procedure.
• Reduced Treatment Time: Zygomatic implants can significantly reduce the overall treatment time compared to traditional implant procedures.
• Enhanced Aesthetics: Zygomatic implants preserve natural gum contours and prevent the “sunken” appearance associated with missing teeth.
• Fewer Surgical Interventions: Unlike bone grafting, which requires additional surgeries and healing periods, zygomatic implants streamline the process.
• High success rate: Zygomatic implants have a high success rate, ranging between 90% and 95%, when performed by expert oral surgeons.

Disadvantages Of Zygomatic Implants

Limited to replacing teeth in the upper jaw only

More invasive procedure compared to the placement of conventional implants

Sensitive procedure, so it requires skilled experts

Longer recovery time

Zygomatic Implant Surgery

Zygomatic implant surgery is a highly specialised procedure aimed at anchoring dental implants in the zygomatic bone (cheekbone). This technique is particularly valuable for individuals with extensive bone loss in the upper jaw. Below, we will delve into the crucial steps of the surgery.

Consultation and treatment planning

Before proceeding with zygomatic implants, our dental experts will ensure you are an ideal candidate for them. All patients with severe bone loss in the maxilla are good candidates for zygomatic implants. General health plays a significant role in determining if you are a suitable candidate. An ideal candidate should be medically free from any conditions that contraindicate surgery in general.

The central step of the zygomatic implant surgery involves the precise placement of zygomatic implants into the zygomatic bone. These implants are uniquely designed to be longer than traditional implants, allowing them to reach the dense cheekbone.

A detailed radiographic examination is essential to determine the exact number of implants required and their precise location, which varies based on individual needs and the treatment plan established.

Implant Placement

The placement of zygomatic implants is a delicate procedure that demands the expertise of skilled surgeons. The precise positioning of these implants is vital for long-term stability and successful treatment outcomes.

• During the consultation, our expert surgeons will determine the most suitable surgical technique to access the zygomatic bone, either through an extra-sinus or an intra-sinus approach.
• Extra-sinus approach: In this technique, the zygomatic implants are inserted without disturbing the maxillary sinus, which minimises the risk of sinus complications and reduces surgical time.
• Intra-sinus approach: This technique involves retracting the lateral wall of the maxillary sinus, allowing the zygomatic implant to pass through the maxillary sinus to reach the zygomatic bone. This approach carries a higher risk of sinus complications, a longer surgical time, and a bulkier prosthesis.

Once in place, these implants provide a robust foundation for supporting the final dental prosthesis.

Immediate Prosthesis (Optional)

In many cases, zygomatic implant surgery offers the remarkable advantage of attaching a temporary prosthesis immediately after implant placement. This immediate prosthesis serves both functional and aesthetic purposes. It allows patients to leave the clinic on the same day with a fully restored smile.

While the placement of an immediate prosthesis is not always possible in every case, our surgeons carefully evaluate each patient’s suitability for this option during the treatment planning phase. This decision considers various factors, including the patient’s overall oral health and the complexity of the procedure.

Closure and Suturing

Following the successful placement of zygomatic implants and, if applicable, the temporary prosthesis, the surgical incisions are meticulously closed with sutures. This step is crucial to ensure proper healing and minimise the risk of infection. The sutures utilised are typically absorbable, gradually dissolving on their own over time.

By securely closing the incisions, our surgeons help create an optimal environment for the healing process. This promotes the integration of zygomatic implants with the surrounding bone.

Recovery Following Zygomatic Implants

Zygomatic implants have a high success rate with minimal complications. It is normal to experience minimal bruising, pain, and swelling after surgery, which typically resolves within the first two days. To control these complications, you are advised to use the prescribed pain medications and use a cold compress for 20 minutes on and 20 minutes off.

As rare surgical complications, some patients may experience wound infection, nerve damage, and sinus infection. These are rare complications that can be avoided by choosing an expert dental surgeon and following the post-operative instructions.

The recovery from zygomatic implant surgery takes around 6-8 months for complete osseointegration to complete. Initial stabilisation and healing occur within 2-4 months, while complete osseointegration is completed after 6-8 months. During that time, you will be able to enjoy daily activities, from smiling, eating, and speaking using your temporary restoration that is loaded at the time of surgery. These are the post-operative instructions that are essential to follow your zygomatic implants for a smooth recovery.

1. Avoid disturbing the surgical site. Do not vigorously swish and brush the surgical site.
2. Avoid smoking during the first two weeks to avoid delayed healing and wound infection.
3. Avoid blowing your nose for the first two weeks.
4. Have sufficient rest and avoid strenuous activities for the first 48 hours.
5. Stay hydrated and drink plenty of fluids for a smooth recovery.
6. During the healing period, it is advised to follow a soft diet regimen and avoid hard and sticky foods to prevent disturbing the osseointegration process.
7. Maintain your oral hygiene by brushing using a soft toothbrush. It is essential to keep your temporary dentures clean to avoid any gum inflammation related to the surgical site.
8. Take the prescribed medications and maintain follow-up visits to monitor the healing process.

Following the post-operative care instructions can guarantee a smooth recovery. However, you should look for any abnormal signs during healing, such as persistent pain and swelling, pus oozing from the surgical site, or fever. If you experience any of these symptoms, consult our dental experts immediately, as it may indicate signs of infection and failure.

In summary, the zygomatic implant surgery is a highly specialised procedure performed at Dulwich Dental Office. It focuses on the precise placement of zygomatic implants, which are longer than traditional implants and anchored in the cheekbone. This approach provides a revolutionary solution for individuals with severe upper jawbone loss. When feasible, the attachment of an immediate prosthesis allows patients to leave the clinic with a fully functional and aesthetically pleasing smile. Our skilled surgeons prioritise your comfort and safety throughout the procedure, ensuring a successful zygomatic implant journey.
