All on Four Implant Technique

The All-on-Four technique allows us to fulfill these wishes for our patients who have too much bone loss. Portuguese Dr. This method, developed by Paolo Malo and his team, involves the application of 4 implants at certain positions and certain angles, and the application of a special prosthesis that includes the gingiva as well as the lost teeth (see hybrid prosthesis).

The quality, length and width of the bone in the patient’s jaws are of great importance in the planning of implant treatments. However, there are anatomical structures in both the upper and lower jaws that may limit the application of implant treatment. In the upper jaw, we can see that the osseous cavity, which we call the maxillary sinus, droops downwards following the extraction of the posterior teeth. This situation may make implantation difficult or impossible in the posterior maxillary region.

In the lower jaw, due to bone loss after tooth extraction, the bone length may decrease and the nerve tissue located in the bone at the back of the jaw may approach the nerve tissue.

The All-on-Four technique allows us to place implants in front of these anatomical structures, thus enabling us to administer treatments to our patients more easily.

The All on Four technique provides the comfort of having fixed teeth for our patients with advanced bone loss.

“What is the Hybrid Prosthesis?”

Hybrid dentures are a type of fixed prosthesis made on implants placed in the mouth. The most important feature of this type of prosthesis is that it also contributes to pink aesthetics. Thanks to the special pink gingival parts of the prosthesis; We can make prostheses with the most aesthetically ideal tooth dimensions for our patients.

Hybrid prostheses are applied to the implants by using special abutments called multiunit abutments, by screwing them at certain force values. The standard practice for implant-supported prostheses was to adhere to the implant abutments using adhesives, as is the case with porcelain restorations made to the patients’ own teeth. Current research, instead, shows that it is healthier for the designed porcelain teeth to be screwed to the implants than to be attached to them.
