Zygoma: zygomatic implants in dentistry

Restoration of the dentition with dental implants is often impossible for a variety of reasons.

One of the most common is the loss of bone tissueinto which the implant is implanted.

These patients can be helped by Zygoma implants, which are attached to the cheekbones and do not require bone restoration.

This is a real find for people who have completely lost their teeth and lost bone tissue.

What are Zygoma dental implants for?

Zygomas can give patients back the ability to chew any food normally and give them an even line of white teeth, when other methods of recovery are difficult to use.

This is due to the design and method of fastening the Zygoma models. The pins are in the form of cylinders and are located at an acute (30-60 °) angle to the jaw. The length of the mounts reaches 5-6 centimeters and provides fixation in the zygomatic bone. This bone practically does not lend itself to resorption, it is more reliable than the jaw, which is often lost and needs to be restored.

The implant is made of titanium, the surface has a porous structure, which ensures fast and reliable fusion with the bone tissues of the cheekbone.

For fixing fixed prostheses, 2-4 Zygoma implants are placed, the angular position provides reliable attachment. Installation is possible immediately after implantation temporary prosthesiswhich is non-removable.

Zygoma is an American model of the implant developed by Nobel Biocare. It is widely used all over the world for the restoration of the teeth of the upper jaw. The related products of Zygomatic made in Israel are also popular.

Note that preoperative diagnostics and Zygoma installation require high professional knowledge, skills, therefore, they are performed by highly qualified specialists in clinics that have the appropriate licenses.

Indications and contraindications

Zygoma technology gives hope to restore teeth to many patients who cannot benefit from other restoration methods.

The indications are:

• loss of bone in the upper jaw;
• unsuccessful procedures sinus liftthat did not lead to bone augmentation, as well as contraindications to its implementation;
• the absence of all the teeth of the upper row;
• inability to wear removable dentures.

Note that the Zygoma can be installed on a part of the jaw only from one side when there is a partial loss of teeth.

Patients with the following problems will have to stop using Zygoma:

• chronic sinus inflammation;
• incoagulability of blood;
• diabetes mellitus in an uncompensated state;
• complex systemic diseases (including cardiovascular), in which operations are impossible.

Contraindications are inflammation in the oral cavity and ENT organs, which can provoke complications when installing zygomatic implants.

Main advantages

The main advantages and benefits of Zygom over other methods of restoration of the dentition:

1. Fastening of implants to the zygomatic bone is reliable, not subject to resorption.
2. The ability to quickly (at one time) restore the entire dentition, immediately put on the prosthesis. Diagnostics and treatment take no more than a week.
3. Long-term implant warranty. Dentures can be changed as needed.
4. No need to build up damaged jaw bones. Possibility of installation for osteomyelitis of the jaw.
5. Modern computer methods of diagnostics and simulation of the installation process, eliminating errors.
6. Aesthetics of the prosthesis.

The method was developed for the treatment of patients after facial trauma or cancer. It guarantees safety for the facial nerve, eliminates injury during the procedure. Zygomatic implants in dentistry allow patients, gradually increasing the load on their teeth, to switch to good nutrition.

Operation stages

Before the start of the procedure, studies and anamnesis are taken, identifying the need and contraindications for conducting. The patient takes a blood test, chronic diseases of various organs are revealed, which can become an obstacle to the installation of Zygom.

The basis for an accurate and comfortable positioning of the prosthesis is the determination of the configuration and features of the jaw. For this, an anatomical model is created. The most modern method is used for diagnostics - multispiral tomography on the computer.

Special computer programs of the medical complex determine the places and angle of implantation. Specialists can 3D print an artificial model of the upper jaw, which will help the surgeon to recreate the tactics of performing the operation on a dummy that accurately repeats the structure of the patient's organ.

Installation:

1. The procedure is performed under anesthesia.
2. Carrying out time - from an hour to two hours, depending on the amount of work.
3. Install from 2 to 4 zygomatic implants. Some of the implants can be attached to the jaw, if possible.
4. At the end of the Zygoma implant placement, a temporary prosthesis is put on. In case of major injury, the prosthesis can be put on in 1-3 days.

After the operation, slight swelling is observed, which disappears in a few days. The patient does not feel pain during the installation procedure. Painkillers are prescribed for the postoperative period.

The temporary prosthesis has a metal frame and is screwed with special screws. During chewing, a slight mobility of the structure stimulates metabolic processes, accelerates tissue regeneration and ingrowth of Zygoma implants into the cheekbone.

Replacement of a temporary prosthesis is possible after osseointegration of Zygoma into the zygomatic bone - in six months or a year.

Prosthetics with Zygoma are not cheap, but if you need to restore the entire dentition, the prices are almost comparable to the total cost of a single dental implantation.

All teeth appear after one procedure, are distinguished by their beauty and reliability. Let us recall the need to choose a good clinic and a specialist, since the method requires high-quality equipment and high professional skill of the doctor.
