Prosthetics for 1 day. Features all-on-4

Problems with health, fear of going to the dentist, metabolic disorders lead to the fact that in adulthood, when people are still full of strength, many are almost completely missing teeth. This is a big problem, since the digestive tract is disturbed, a person experiences difficulties with eating solid food and suffers from aesthetic problems. People are forced to eat monotonously, vitamins are not enough, because of what worsens the condition of the skin and hair.

And the problem is global: in the West, the number of those who have almost completely lost their teeth reaches 40 million, and in Asia, 250 million.

Implantation of teeth or removable dentures - which option to choose?

For a long time, the option of treatment for people with missing teeth was only removable dentures. This is a budget option, but it gives a lot of problems - the prosthesis rubs the gums, it's hard to get used to massive structures, they can fall out of the mouth when chewing.

The second option is more expensive, this is implantation of the teeth, but the prostheses are securely fixed in the mouth, they are light, do not discomfort and do not rub the gums. But here lies another problem. With a long absence of teeth, bone tissue simply atrophies (decreases in volume), classical implantation is difficult, sometimes impossible.

But the output can be found in any situation, in this case it is an implantation application with immediate load using all-on-4 technology.

What is the essence of the methodology?

On a note! If you are looking for a truly original technique, the attending physician must receive training, a practical course and a certificate from Nobel Biocare. Many clinics use the name of the technique as an advertising move and do not know its essence. Important: the technology is patented by Nobel on specially designed implants.

Implantation using the "all-on-four" technique involves the use of only 4 dental implants, two of which are placed in the frontal zone and two in the lateral zone. In this case, the distinctive feature is that lateral models are fixed at an inclination. For comparison, in the classical method it is important to place the implants strictly vertically, otherwise they simply will not get accustomed.

To understand if the technology "teeth are all for four" is suitable for you, you need to study the essence of the matter in detail.

Implantation "all for four" has some features :

• Implants are fixed at a certain angle, so the doctor manages to find bone areas with a strong tissue and bypass the nearby nasal sinuses and nerves;
• The method is applied only in case of complete adentia, when all the teeth are missing in the row, if there are movable or sick teeth, they are removed (but implants are not installed in the same well, but are placed side by side);
• When installing implants all-on-4, computer simulation is mandatory: the whole treatment process is worked out with the help of special software, which minimizes the risk of human errors and obtains the predicted result;
• At the stage of preparation for treatment computed tomography is mandatory - the data of the obtained image of the jawbone are used for 3D modeling;
• The method involves the use of special templates that help to place implants in a precisely verified location, according to a pre-modeled plan;
• When prosthetics use implants, which consist of two parts. The implant itself is implanted in a traditional way - by means of a surgical operation, in which an opening is formed inside the bone, and the gum is cut and peeled for this. The second part is the tip of the implant or the abutment. When installed on inclined implants, the abutment is also selected with a certain angle (multlunit design). This allows you to straighten the position of the prosthesis and align the bite;
• Prosthetics on all-on-4 technology Immediate installation of a non-removable prosthesis;
• After a few days the patient can eat normally. Since the prosthesis is designed for the entire dentition (up to 12 crowns in a row), this allows the implants to be firmly attached to each other. In this case, patients can be offered both a new prosthesis and a removable structure that they used to wear before. Simultaneously, due to the masticatory load, physiological processes are started in the bone tissue, and bone is restored more quickly.

Why is all-on-4 better than classical implantation?

All-on-four prosthetics has several advantages:

• Implantation "all for four" - this is the shortest period of rehabilitation;
• Prosthetics are very fast and comfortable for the patient;
• This technique is useful for bone tissue - it can almost immediately receive a load, which contributes to the regeneration process;
• Implantation of all-on-4 is cheaper than classical (if you compare prosthetics on similar brands of implants). This is due to a reduction in the number of "screws" and the number of visits to the doctor;
• The method excludes risks through careful study of the whole process of treatment on the computer;
• Prosthetics all-on-4 allows you to give teeth aesthetics, improve speech and return lost self-esteem in the shortest possible time.

But, despite the obvious advantages, the technology has some drawbacks. They are not so critical, but you should pay attention to them.

1. The manufacturer declares that the technique is suitable for atrophied tissue, but in practice the implantation with loose or insufficient bone is practically impossible. The protocol itself implies the installation of lateral implants in a strictly defined place, so that the correct bone loading is necessary. But some implantologists go for violations and, in the presence of atrophied sites, shift the implants slightly forward. In a few years, this leads to the fact that the prosthesis must be corrected, and the bone continues to atrophy.

Important! This method is recommended to be performed only with sufficient bone volume or slight shrinkage to comply with all the recommendations of the developer of the original technique.

2. Some appreciate the speed of the method, others consider it a minus point that the prosthesis is performed immediately on the gum tissue damaged during the operation. Because of this, inflammation and soreness may occur. Solve the situation allows the shift in terms of prosthetics - if they are delivered not on the same day, but in a couple of days after the operation, the risk of inflammation will be reduced to a minimum.

3. And one more minus of the given technique: implants are established by classical lateral way - through an incision of a gum and the subsequent imposing of seams. So, the patient needs to prepare for a long rehabilitation. Similar shortcomings are deprived of other methods of immediate loading, read about them below.

How much will treatment cost

On the All-on-four the price is very high, as the company "Nobel" uses the most advanced equipment for the production and installation of implants, invests a lot of money in research and implementation of innovative technological solutions.

The cost of treatment on the original "screws" of the Nobel brand will cost in the amount of 400 thousand rubles. The price includes materials, work, inspections, diagnostics, making pictures, anesthesia.

The method of prosthetics on four implants is certainly very good. Especially if the doctor follows all the protocol requirements and uses the original implants. By the way, today and other companies began to develop models for this technology of prosthetics, and some of them have in the arsenal of very successful models. In addition, treatment costs two times cheaper.

Does the method have alternatives?

Recall that this method is recommended as an alternative to the classical approach, is carried out with full adentia and is necessary, when the bones are enough to fix the implants. But what to do to patients who have pronounced atrophy caused by a long absence of teeth?

You can consider several options:

• Prosthetics all-on-6 , which is carried out in violation of the volume of medium degree. Osteoporosis and inflammatory processes on the gums are not an obstacle. A greater number of support points allows better distribution of the chewing load. In addition, other models of implants are used - they involve deeper and stronger sections of the jaw.

• Basal implantation : similar to prosthetics on six implants, but indications for it are acute problems of bone tissue. That is, if it is catastrophically small, this method is used. Unlike the previous protocol, the number of implants is increased to 8-12 pieces. On the whole row. In the rest - all the same: instant loading, installation of implants in deep and strong departments of a bone.

Another option for solving the problem of full adentia is the use of mini implants on MDI models. These are thin and very miniature implants, which are screwed into the bone without trauma to the tissue. But they are only able to support removable dentures, which rely on the gums. This technique proved to be not on the best side - due to lack of exercise, bone tissue continues to atrophy, implants fall out together with prostheses.

In order for the implantation of teeth to be comfortable and without complications, it is necessary to choose a professional implantologist who possesses various techniques in perfection, has received appropriate training and has valid certificates. Be sure to listen to what the doctor advises you, and follow his recommendations faithfully.
