Zygomatic implants are an innovative technique for inserting implants when there is insufficient bone in the maxilla (upper jaw).
They offer a solution for patients who are not ideal candidates for implant placement by providing a fixed restoration.

Zygomatic Implants: An Overview

Zygomatic implants provide a solution for full-arch restoration when there is insufficient bone support for conventional implants.

Zygomatic implants are embedded in the zygomatic bone on each side of the upper arch. The zygomatic bone, also known as the cheekbone, is denser and stronger than the jawbone.

They act as the foundation for all on four implant restoration, where four conventional implants are inserted in a predetermined position and distance from each other.

A temporary restoration is loaded on the same day.

Difference between Zygomatic Implants and conventional dental implants

Zygomatic implants are similar to conventional dental implants in that they are metal fixtures inserted into the bone.

Zygomatic implants are inserted in the cheekbone, while conventional implants are placed in the jawbone.

They also differ in their lengths. Zygomatic implants are lengthier compared to conventional implants. Their lengths range between 35-55 mm and are directed at a 45-degree angle.

Indications of Zygomatic Implants

  • Rehabilitation of a severely resorbed maxillary arch.
  • To avoid sinus lift and bone graft procedures.
  • Failure of conventional implant placement, sinus lift procedure, and bone graft.
  • Rehabilitation of cases with maxillary resection due to tumor or trauma.

Preparation Phase

A detailed medical history is collected to ensure you are medically fit for the surgery.

Due to the extensive drilling distance, a thorough investigation using cone beam CT is necessary to assess the bone condition and anatomical landmarks, particularly the extension of the maxillary sinus.

A team of our finest oral surgeons and prosthodontists determine the number, dimensions, and locations of zygomatic and conventional implants to be used.

Surgical Procedure

The surgery is conducted under either general anesthesia or local anesthesia, which blocks the nearby nerves. Then a full flap is raised, and the bone is exposed.

The access to the zygomatic bone may be through:

  • Intra-sinus approach: The path for drilling the zygomatic bone starts from the crest of the alveolar ridge and then proceeds to the lateral wall of the sinus space. The sinus membrane is elevated, and a specialized drill is used to prepare the implant space in the zygomatic bone. The implant emerges from the oral cavity nearly at the center of the alveolar ridge.
  • Extra-sinus approach: The drilling path extends from the lateral wall of the maxilla towards the root of the zygomatic bone without penetrating the maxillary sinus space. The implant is emerging buccal to the maxillary sinus and appears in the oral cavity near the crest of the alveolar ridge.

The extra-sinus approach results in less post-operative pain, swelling, and inflammation of the maxillary sinus compared to the intra-sinus approach. Special instruments are used to prepare the zygomatic bone for implant placement. Then, the edentulous ridge is prepared for conventional implant placement.
After all the implants are secured in their places, a temporary denture is loaded to provide you with function and aesthetics until complete bone fusion around the implants. After complete healing, the temporary denture is removed, and the final denture is constructed.

Advantages of Zygomatic Implants

  • Increase the denture stability in case there is no sufficient bone.
  • Reduces the treatment time as it eliminates the need for bone graft procedures.
  • Immediate loading of the restoration so you can walk out with a complete smile.
  • Improve the masticatory function esthetics and speech for patients who were not eligible for implants and suffered from ill-fitting dentures.
  • Long lasting.

Disadvantages of Zygomatic Implants

  • Complex procedure and require a highly trained, experienced dentist.
  • Expensive as it requires highly specialized instruments.
  • Longer recovery time compared to immediate loading conventional implants.

Instructions following a Zygomatic Implant surgery

Following zygomatic and all on four implant placement and loading, you may experience some pain and swelling in the first few days.

  • To control the pain, use the painkillers prescribed by the surgeon.
  • To minimize the swelling, use ice packs for 20 minutes on and 20 minutes off during the first two days. On the third day, use a hot towel to accelerate the disappearance of the bruising.
  • Take the prescribed antibiotics to avoid any infection at the surgical site. Also, antibacterial mouthwashes may be beneficial.
  • Within the first few days, you may experience minor bleeding. Place a moist gauze or a tea bag wrapped in a gauze over the bleeding site.
  • Follow a soft diet regime for a few days after the surgery.
  • Avoid smoking and alcohol intake to promote healing.
  • Do not blow your nose or sneeze during the first two weeks after surgery.
  • Maintain oral hygiene measures, but avoid brushing the surgical site for a few weeks.

Maintain your follow-up appointments to allow your surgeon to monitor the healing and osseointegration of the implants. Once the implants heal, the temporary restoration is substituted with a permanent one, giving you a long-lasting, confident smile.

If at any time you experience increased pain intensity with time, unresolved swelling, or implant loss, consult your doctor immediately.

Frequently Asked Questions

Zygomatic implants are titanium fixtures inserted in the zygomatic or cheekbone rather than the jawbone. They act as an anchor for the final restoration when severe bone resorption exists.

Zygomatic implants offer a solution to restore missing teeth in the upper jaw when there is severe bone loss, making it difficult to use conventional dental implants.

Zygomatic implants are inserted in the cheekbone to act as a base for the final restoration, while conventional implants are placed inside the jawbone. Zygomatic implants are also longer than conventional implants.

As with conventional implants, with proper care and maintenance, zygomatic implants can last a lifetime.

I had a wisdom tooth removed and a filling today, I cannot fault my treatment! My dentist was very skilled and calming! I didn’t even feel the injections! Restored my faith in dentists! TOO CLASS!!

I would really recommend this Dental Practice. Dr Kolar is a very attentive dentist who cares about the you as a person as well as about the health of your teeth and gums. He takes time to explain the processes he is leading you through, explains how your dental health has progressed over time and encourages you to take care of your teeth. For the first time in my life I look forward to coming to the dentist!

Toby R.

I have been registered at this dental practice now, for just over 15 years. Throughout that whole period, I have been lucky enough to have been looked after by the wonderful, and patient, Dr Prasad. He has covered many procedures in my mouth, from extraction, and root canal, right up to the most recent procedure, Composite bonding of my broken two front teeth. Do not hesitate to register at this practise, as you will be looked after with care and consideration.

Thank you Dr Prasao

Suzanne L.

Very friendly

During the lockdown period I was able to see Dr Irfan for a dental emergency I had. I’m so grateful that they have been available throughout this. Gillian the practice manager contacted me and offered me an appointment the same day. I am a long standing patient at this practice and cannot thank them enough for great service they have provided to me throughout the years. Great dentist, staff and management. Thank you all so much.

Susan L.

The Dental Care Center has been an excellent dentist surgery that I have been attending as a patient for many years. When I was young I didn’t have a pleasant experience with my local dentist on more than one occasion. I found the dentist at Camden dental care center very reassuring and comforting. The management and reception were also very welcoming.

Stewart S.

Dr Yasha saw me when my teeth were a mess, I was super self conscious about it and it was affecting my life really negatively. I needed 3 bridges, which are still holding up great, and I’m on the practice plan so have the motivation to go in for regular hygienist and checkup appointments. Not only is my oral health better than ever, my overall wellbeing and peace of mind is immeasurably improved. The care and consistency of treatment I’ve received from Dr Yasha and hygienist Ramin has made going to the dentist (almost) a pleasure. 100% would recommend. Really great people doing excellent work.
