Zygomatic implants are a new and advanced dental technique intended for patients with severe maxillary (upper jaw) resorption. These implants are a good substitute for traditional dental implants. This ‘graft-less technique’, also known as the ‘Zygoma technique’, was introduced by Prof. Branemark & Nobel Biocare, Sweden.
What are Zygomatic Implants?
Zygomatic (Zygoma) implants give a ray of hope for dental patients in need of dental implants who have severe maxillary (upper jaw) resorption. This implant procedure eliminates the need for bone grafting (bone augmentation).
The zygoma implants (unlike regular ‘root type’ dental implants) are inserted into the zygomatic bone (cheekbone) to give support for maxillary teeth (upper jaw teeth), bridges and dentures. The zygoma, which is a very dense bone, provides excellent support for dental implants. In fact, a complete arch can be replaced at once.
Zygomatic implants are appropriate for dental patients who have lost bone mass due to a variety of factors, including severe periodontitis. This dental technique uses the cheekbone or the zygoma bone to support the longer zygoma implants.
When people lose teeth or have periodontal disease, the zygomatic bones do not lose mass. Even if their bone mass is insufficient for standard dental implants, patients with this new dental treatment can have a beautiful and functional smile.
Usually, normal dental implants are inserted into the jawbone; however, if you have upper jaw bone loss, the bone may be too weak to support a traditional dental implant and will result in dental problems.
Advantages of Zygomatic Implants
No bone grafting required:
Patients with upper jaw bone loss required bone grafts to maintain their dental implants in position prior to the introduction of zygomatic implants. Unfortunately, it used to take six to twelve months for bone grafts to heal before dental implants may be implanted.
But in the case of zygomatic implants bone grafting is not required (graft-less technique / Zero graft technique) so the patient can have a new beautiful smile as soon as the implantation surgery is completed.
No need for sinus lifts:
Some individuals may require a sinus lift operation prior to implant placement if the upper jaw loses bone mass. Sinus lifts surgery strengthens the bone between the mouth cavity and the sinus so that implants do not injure the sinus cavity.
Patients must then wait for many months for the area to heal before receiving their new teeth. Because zygomatic implants do not require sinus lifts procedure, the implant procedure is simplified and quick.
Enjoy new teeth right away:
Because zygomatic implants are guided straight into the cheekbone, the implants can be inserted immediately. These implants provide immediate biting ability involving hard food stuff. Having new teeth quickly can boost self-confidence along with good looking teeth and a smile. If a patient has zygomatic implants, they do not need to wait for healing!
Can be used in conjunction with traditional implants:
In addition to conventional implants, zygomatic implants can be used to replace teeth both in the upper and lower jaws
High success rate:
The success rate of zygomatic implants is higher than 97%, which is comparable to that of normal dental implants. It also involves less discomfort for patients.
How long do zygomatic implants last?
Zygomatic implants are a safe and effective dental treatment option having an excellent survival rate even after 12 years. Zygomatic implants procedure is beneficial for patients who have lost their jawbone and would want to avoid a bone graft or sinus lift procedure.
Disadvantages of Zygomatic Implants
Although zygomatic dental implant surgery has a high success rate and is regarded as a very safe and efficient alternative to bone grafting, it does come with some disadvantages like sinusitis.
There is a good probability that sinusitis may develop after the placement of a zygomatic implant and it can also be treated. But it can be challenging, and implant loss is a possibility. In the event there can be peri implantitis or osseointegration failure.
Zygomatic implants were thought to be a workable substitute for bone grafting in the rehabilitation of the edentulous atrophic maxilla. However, zygomatic implant problems such as sinusitis can be challenging to control or lead to a loss of implant; as a result, care should be taken when using them.
What is the cost of Zygomatic implants in India?
The average cost of zygomatic implants in India starts from Rs. 60,000. But the cost of zygomatic implants may vary according to many factors such as the patient’s general health, the location and also the dental clinic in which the treatment is going to be done.
