Zygomatic dental implants are a type of dental implant that’s anchored in the cheekbone (zygomatic bone) instead of the upper jawbone. They’re designed for patients with severe bone loss in the upper jaw, where traditional implants can’t be placed.
These implants are longer than standard implants, typically ranging from 30 to 60 millimetres in length. This added length allows them to securely anchor in the dense zygomatic bone, providing a stable base for the prosthetic teeth without requiring bone grafting.
The success rate of zygomatic dental implants is high, with studies showing an average success rate of 94 — 96% over several years of follow-up.

How are Zygomatic Dental Implants Different from Regular Dental Implants?
Zygomatic implants differ from traditional implants in their placement, length, and complexity. While traditional implants are anchored in the jawbone and require adequate bone density, zygomatic implants are placed in the cheekbone, making them suitable for patients with severe upper jawbone loss.
| Aspect | Zygomatic Implants | Traditional Implants |
|---|---|---|
| Placement | Anchored in the cheekbone (zygomatic bone). | Anchored in the jawbone. |
| Bone Requirements | Designed for patients with severe upper jawbone loss. | Need sufficient jawbone density to support the implant. |
| Length | Zygomatic dental implants are longer than traditional implants, ranging between 30 and 60 mm. | Traditional implants range between 6 and 16 mm. |
| Surgical Complexity | Requires a more involved surgical procedure, but fewer surgical appointments overall. | Less complex, involving a straightforward placement procedure into the jawbone. |
| Recovery Time | Shorter recovery time due to the placement in denser bone. | It has a longer healing period as the implant integrates with the jawbone. |
| Cost | Zygomatic implants are more expensive due to the specialised nature of the procedure and the longer implants used. | Lower cost due to a less complex procedure. |
| Longevity | Slightly higher success rate and, when well-maintained, can last for many years. | High success rate with proper care; lasts decades. |
| Patient Suitability | Zygomatic implants allow patients with extensive bone loss in the upper jaw to get durable restorations. | Best for patients with adequate jawbone density. |
Who Would Benefit from Zygomatic Dental Implants?
Zygomatic dental implants are ideal for people with severe upper jaw bone loss. They may be recommended for those who:
- Experience severe bone resorption in the upper jaw
- Have advanced gum disease (periodontal disease)
- Suffered from jaw trauma or injury
- Have worn dentures for many years, leading to bone loss
- Require specialised treatment for complex dental issues
- Are missing multiple teeth or have severely damaged teeth
What are the Benefits of Zygomatic Implants?
Zygomatic implants provide stability, a natural look, faster recovery, and avoid grafts or sinus lifts. They’re reliable, durable, and ideal for severe bone loss, offering a comfortable and effective alternative to traditional dental implants.
| Benefits | Description |
|---|---|
| Improved Stability | Provides a strong, stable foundation for dental restorations, especially for patients with bone loss in their upper jaw. |
| Natural Look and Feel | Zygomatic implants can help restore the natural appearance of the face and smile, improving both function and aesthetics. |
| Shorter Treatment Time | Often allows for immediate attachment of teeth, reducing the overall treatment timeline. |
| Quick Recovery | Most patients can return to their daily routines within a few days after the procedure. |
| Alternative to Bone Grafting | Direct placement in the cheek bone removes the need for grafting procedures. |
| Simpler Procedure Without Sinus Lifts | Avoids the need for sinus augmentation, making the treatment faster and less complex. |
| High Success Rate | It offers consistent outcomes similar to conventional implants, making it a dependable option. |
| Durable and Long-Lasting | With proper care, these implants can remain functional for decades. |
| Minimally Invasive Approach | Skips complex surgical procedures like grafting, reducing surgical strain. |
How does the Zygomatic Implant Procedure Work?
The zygomatic implant procedures involve careful planning, precise placement of implants into the cheekbone, securing temporary teeth soon after surgery, and fitting permanent restorations once healing is complete.
1. Initial Assessment and Imaging
The process starts with a thorough evaluation, including 3D imaging, to assess the bone structure and determine the best positions for implant placement. This planning avoids important oral and maxillofacial structures like nerves and sinus cavities.
2. Anaesthesia for Comfort
Local anaesthesia, often combined with sedation, is used to keep the patient relaxed and free from pain throughout the procedure.
3. Gum Incision
A small incision is made in the gum to expose the bone. This step provides access for preparing the implant site.
4. Preparing the Bone Pathway
The surgeon carefully drills an angled pathway from the upper jawbone to the zygomatic bone using specialised tools. This makes sure the implant has a secure and stable fit.
5. Inserting the Implant
The long zygomatic implant is placed into the prepared pathway and anchored in the cheekbone, providing stability in cases of significant bone loss.
6. Suturing the Incision
The incision is closed with sutures, protecting the site and initiating the healing process.
7. Temporary Teeth Placement
In many cases, a temporary prosthetic is attached to the implants shortly after surgery. This provides functional and aesthetic benefits while the implants heal.
8. Attaching the Final Prosthetic
After the healing period, during which the implants integrate fully with the bone (osseointegration), a customised, permanent prosthetic is fitted. This final restoration is designed for durability and a natural appearance
Are There Risks to Zygomatic Dental Implants?
Yes, zygomatic implant surgery does have some risks. Your oral and maxillofacial surgeon will explain the risks and the steps they take to prevent them. The potential risks and complications include:
- Surgical Complexity: The procedure is intricate, requiring precise angulation and placement into the zygomatic bone, which may increase the risk of surgical errors.
- Sinus Involvement: Due to the proximity to the sinus cavities, there’s a possibility of sinus-related complications, such as sinusitis or perforation.
- Nerve Damage: Improper placement can lead to nerve injury, resulting in numbness or altered sensation in the facial region.
- Infection Risk: As with any surgical procedure, there’s a chance of infection at the implant site, which could affect healing and implant success.
- Implant Failure: Factors like poor bone quality, inadequate osseointegration, or excessive stress on the implant can lead to implant loosening or failure.
- Soft Tissue Complications: Issues such as gum recession or inflammation around the implant may occur, potentially compromising aesthetics and function.
Are There Alternatives to Zygomatic Dental Implants?
Alternatives to zygomatic implants include pterygoid implants, traditional implants with bone grafting, the All-on-4 technique, and subperiosteal implants.
| Alternative | Description |
|---|---|
| Pterygoid Implants | Anchored in the pterygoid bone behind the upper jaw, offering support without bone grafting. |
| Subperiosteal Implants | Placed under the gum but above the jawbone, suitable for patients who cannot undergo bone augmentation. |
| All-On-4 Implants | This uses four strategically placed implants to support a full arch of teeth, often avoiding the need for bone grafts. |
| Bone Grafting with Traditional Implants | Bone grafting procedures can augment the jawbone, allowing for the placement of standard dental implants. |

FAQs on What are Zygomatic Dental Implants?
Can You Choose Zygomatic Implants or Must a Specialist Recommend Them?
You can’t independently choose zygomatic implants. While you may have concerns about your dental health and potential treatment options, the decision to undergo zygomatic implant surgery should be made in consultation with an oral and maxillofacial surgeon or experienced dental professional to determine if it’s needed.
Can Zygomatic Dental Implants Replace Multiple Teeth?
Yes, zygomatic dental implants can replace multiple teeth. They’re used to supporting a full set of replacement teeth in the upper arch, even if there’s insufficient bone in the upper jaw.
