Maxila treatment without bone grafting
What is multidisciplinary implantology?
The Implantology Centre offers treatment and rehabilitation for missing tooth problems with fixed solutions. In recent years, there has been significant progress in the techniques and materials used by clinics and in the field of dentistry as a whole. Computer-assisted surgery and the metal-free concept are examples of this progress. The metal-free concept allows for fixed and quality prostheses without metal.
In addition to this, the Implantology Centres have experts in several fields of medical science who provide a high quality of care that is more comprehensive and precise.
What is All-On-4?
The original concept of All-On-4 enables edentulous patients, with severe maxillary atrophy, implantology rehabilitation without bone grafting. The upper jaw is more liable to bone loss, mainly due to tooth loss, but also because sinuses can end up too close to the jaw. For this reason, the upper jaw bone is generally limited. Our implantology centres frequently see cases of patients with bone only in the back area (from canine to canine). People with these traits are special candidates for rehabilitation with and overdentures (acrylic and fixed prostheses with implantation).
This procedure places two implants at the back of the jaw, tilted up to 30º where there is bone missing, and two implants in the front of the jawbone. This is the original concept for the procedure known as All-On-4, which allows for the improvement of the support area, and the screwing of the fixed and hybrid prostheses or ceramic prostheses with 12 teeth.
What is the major difference between All-On-4 and dentures?
- Dentures can be removed for cleaning, whereas the All-On-4 is fixed. Patients cannot remove them after eating or at night.
- Dentures move and complicate the chewing of food. All-On-4 allows you to easily chew and savour your favourite foods.
- These prostheses rest on the gums and, therefore, may hurt or cause small wounds. However, All-On-4 is fixed on the implants and, if well adapted, small wounds or swelling will rarely occur.
- Bone loss is reduced. Using dentures will progressively reduce bone density, which will lead to maladjustment of the dentures.
- All-On-4 does not have a palate and, for that reason, the flavours of food will be stronger.
What is the difference between conventional implants and All-On-4 implants?
In the past, dentists would have to place implants one by one; around eight, nine, ten or twelve, sometimes even twenty, to restore both the upper and lower jaw. This was an expensive treatment. Besides the high cost, the surgery and recovery of the patient would take longer. With All-On-4, you can easily place four implants and, in most cases, it is not necessary to add bone during the treatment. Thus, with only one surgery appointment and without bone grafting, the treatment duration is reduced and will be completed in less time.
Who can be a candidate for this treatment?
Overall, everyone is a potential candidate for an All-On-4 treatment.
Is it a painful procedure?
This procedure is carried out with a nerve anaesthetic block, so there is no pain or complications. It is a simple and pain-free surgery. Minor discomfort is possible, but only on the first or second day.
What is the All-On-4 success rate?
The implants can last years, decades, and even for a lifetime depending on hygiene habits, cleaning precautions, periodic checks, and the absence of systemic diseases, such as diabetes or oncologic problems.
What is the planning procedure for All-On-4 treatment?
These procedures are planned with CT scans, which provide high quality three-dimensional images of the target area. A radiographic image will guide the procedure by giving information about the angle and implant diameter, as well as every other aspect involving the procedure.
How much does All-On-4 cost?
The price varies depending on the country or region.
All-On-4 angled dental implants are placed where the bone density is higher. Hence, expensive and time-consuming bone grafting surgeries, such as sinus lift, are not needed. Bone grafting requires a waiting and healing time that can take months;
All-On-4 dental implants are specially suited for complex cases once considered impossible;
This treatment simplifies the oral rehabilitation process and allows patients to use a screwed, fixed prosthesis over the All-On-4 implants, even when the bone has a low density;
In economic terms, the full cost is much lower when compared to single implants. With four implants, it is possible to screw a fixed prosthesis with a full arch of teeth;
Maintenance and hygiene of the fixed prosthesis is very simple;
Enables the chewing and eating of all kinds of solid foods;
Frustration and discomfort caused by removable prostheses will disappear;
There is a high chance of All-On-4 treatment lasting a lifetime. The duration and lifespan depends on maintenance;
Patients treated with this protocol will acquire a youthful appearance through the improvement of facial structure. The person’s appearance will be greatly enhanced.
Conclusion about All-On-4 dental treatment
The above-mentioned original concept consists of speeding up the placement procedure and avoiding bone grafting by circumventing anatomical limitations.
In some cases, our implantology centres feel that is important to improve fixed prosthesis support by increasing the number of inserted oral implants. In most clinical cases, we recommend placing five or six titanium rods on the upper jaw to ensure the lifespan and stability of the treatment.
