Bone loss is a huge factor in whether a person can receive dental implants or not. The dentist will take a few radiographs before starting the procedure. This shows the “sensitive areas” before implant placement. Because of the fragile anatomical structures surrounding the jaw, the bone mass available under the maxillary sinus and above the mandibular sensory nerve is often very limited. This is why with traditional methods it is often impossible, without bone reconstruction, to place implants in the bottom of the upper and lower jaw. The solution: All-On-4 Dental Implants.
The All-On-4 technique helps to circumvent the anatomical “obstacles” mentioned above: the implants of the bottom are laid by tilting them forward at an angle of 30 to 45°. Since the bone of the anterior part of the jaw is often in better condition, it can be used without problems occurring. This makes it possible to obtain better results and to avoid any contact with the maxillary sinus and the mandibular nerve. The use of much longer and stronger implants is made possible by this angle of inclination. The implants can be loaded immediately with a fixed prosthesis on the day of the operation. Today, experts can say with certainty that inclined implants are just as effective in the long term as other options.
Titanium implant procedures take about two to three months and, in the case of bone reconstruction, it can take up to six months to “anchor” to the bone. This extremely solid anchorage between bone mass and titanium is called osseointegration. Immediate loading is performed when a fixed prosthesis (for example, a bridge) is mounted immediately on the implants that have just been placed, without needing a healing period. When all teeth have to be removed, immediate loading brings important advantages to the table: the patient receives a fixed bridge in a few hours instead of a complete removable prosthesis. This bridge is aesthetically pleasing and can be used normally. The All-on-4 procedure consists of installing artificial teeth fixed on as few as four implants to rehabilitate a complete dental arch. However, the so-called “traditional” implantology methods generally require six to eight months or more.
