All on Four implant treatment is an innovative solution for patients with tooth loss. Four implants are placed in the jawbone to provide fixed prosthetic support and patients can get their new teeth on the same day. Unlike traditional implant methods, All on Four treatment can be applied without the need for bone grafting and offers a faster healing process. So, how is this technique applied, what are its advantages and who is it suitable for? Here are all the details!

What is All on Four Implant?

All on Four Implants, also known as quad implants, have been developed for patients with complete tooth loss or severe tooth loss. It is made with a prosthesis fixed on only four implants. It supports a complete dental bridge that replaces missing teeth in the upper or lower jaw. In All on Four implant treatment, two implants are placed perpendicular to the front of the jawbone and the other two implants are placed inclined to the back. This method makes implant placement possible even in cases of insufficient bone density.

Who is All on Four Implant Treatment Suitable for?

All on Four treatment is a solution for patients who have lost all their teeth or who have suffered severe tooth loss. It is also effective for patients who are uncomfortable with traditional removable dentures. In some cases, dentures can cause irritation and discomfort. For these patients, the teeth are fixed. It is also an ideal alternative for patients who cannot undergo conventional implant treatment due to insufficient bone tissue.

Patients with reduced jawbone volume are not suitable for traditional implant procedures, which often require bone grafting. All on Four can be performed with minimal bone volume.

How is an All on Four Implant Made?

The All on Four technique is a scientifically recognized technique that has been used for more than 20 years. Two implants placed in the posterior region of the jaw at an angle of 30 – 45 degrees are supported by two implants added perpendicularly to the anterior region. In this way, anatomical obstacles such as sinus cavities and lower jaw nerve are prevented. The chance of a fixed prosthesis increases.

At the very beginning of the All on Four treatment process, the patient’s oral health is examined in detail. The jaw bone structure is evaluated with digital scans and X-ray images.

Then the implants are placed. During the surgical procedure, all four implants are placed in the jawbone. The procedure usually takes 1-2 hours and is performed under local anesthesia. Patients receive their temporary prosthesis on the same day. While the temporary prosthesis is used for 3-4 months, the implants are allowed to fuse with the bone. At the end of this period, the patient is fitted with permanent prostheses.

What are the Features of All on Four Implants?

Differences between All on Four Implants and Regular Implants
