Quattro Ti or Acry Free – which is better?

June 21, 2019

In the 21st century, removable dentures fade into the background when it comes to solving the problem of edentia, and patients more often choose dental implantation, which allows them to get results quickly and for a long time. However, not all people have the financial means to restore their teeth with implants, so some choose removable devices. The editors of the UltraSmile.ru portal warn that if, due to circumstances, you are going to wear removable devices, then give preference to the highest quality and most reliable ones. For example, you can choose Quadrotti or Quattro Ti prostheses. We propose to talk further about their positive features.

Question for a specialist
Dental prostheses “Quadrotti” are a patented development of the Quattro Ti company. They belong to removable prosthetics, but at a higher level. “Quadrotti” are new generation designs that are used for partial tooth replacement. Today they compete with nylon prostheses, surpassing them in comfort, elasticity, lightness, aesthetics and service life.

Design features of the Quadrotti system

Quadrotti dentures are made from a material called Dental-D (patented by Quattro Ti) - a nylon-based plastic that is processed under high temperatures1. This model refers to dentures without a palate; it is installed on the upper or lower jaw, but is not used in cases of complete absence of teeth.

The entire prosthesis is created from one solid piece of material and consists of several main parts:

  1. artificial gum: it is created from white translucent or pink plastic - the material is the basis for the entire prosthesis, and its continuation are hooks that clasp the supporting living teeth at the base. White gums are not aesthetically pleasing enough, but the white hooks merge with the enamel of the teeth, so they are completely invisible to your interlocutors. Pink gums are more aesthetically pleasing, but if the hooks are located in the area of ​​the front teeth, they slightly reduce the length of the supporting teeth. Therefore, the color of artificial plastic gum should be chosen depending on the number of lost teeth and the location of the future prosthesis,
  2. artificial teeth: These are ordinary dental crowns that are usually created from plastic. Less often - from ceramic composite or ceramics (but the systems will be very expensive). They are securely fixed in the plastic base,
  3. fastening elements: the hooks with which the prosthesis is fixed in the oral cavity are not made of metal, but of soft thermoplastic, which does not injure the enamel and does not create discomfort for the patient. They can be either white or pink - this, by the way, is one of the design features of this system.

On a note! In some Internet sources you can find information that these are American prostheses. In fact, the manufacturer is an Italian company. Sometimes on the Internet its name is written as follows: Quadrotti, but the correct name will be Quattro Ti - in accordance with the name of the manufacturer.

The prosthesis fits snugly to the soft tissues of the oral cavity, is lightweight and flexible, but at the same time quite durable and holds securely in place.

Dentures distribute the chewing load quite well

The wear-resistant material fits tightly to the gums, it is very flexible, so it easily adapts to mechanical loads, redistributes the chewing load between the periodontium, periosteum, palate and supporting teeth. The likelihood of its breakdown is reduced to zero (but if such a situation arises, if cracks and chips appear on the structure, technicians will easily carry out repairs), and Quadrotti prostheses can be used for 5 or even 7 years. But it’s worth doing this with a few considerations:

  • During its operation, bone tissue sags: in those places where you have no teeth, its atrophy will be inevitable, since in this place the bone does not receive loads from the inside, as usually happens when there are viable roots in it. As a result of subsidence of the mucous membrane, you will have to go for correction of the device - otherwise it will no longer fit tightly to the gums and the question will arise about the reliability of its fixation,


    The use of dentures will not relieve jaw atrophy

  • the supporting teeth are destroyed: do not forget that in those places where the hooks are fixed, special pressure and load are placed on the supports. And the service life of the prosthesis itself will directly depend on their health and quality. If worn-out roots or crowns have to be removed, then the removable prosthesis “Quadrotti” cannot be used; if it is completely edentulous, it will not fit; alternative options will have to be considered - nylon or acrylic of the new generation, “Acry Free”, or dental implantation. If you manage to save at least the roots, then you can think about dentures with locks.

How the structure is installed

  1. selection of colors for the future prosthesis and its base - so that it blends with the gum,
  2. taking an impression to give the prosthesis the correct anatomical shape and ensure maximum comfort for its owner, taking into account the characteristics of the bite,
  3. creating an impression on the basis of which a removable denture will be cast in a dental laboratory,
  4. As a rule, 2 weeks pass from the first visit to the final stage of installation and adjustment of the prosthesis. At the final stage, the doctor tries on the prosthesis and, if necessary, makes adjustments.

Advantages of Quadrotti models

Modern Quattro Ti prostheses stand out against the background of similar designs for partial removable prosthetics. Among the key advantages of this model, experts highlight the following points:

  • excellent aesthetics due to the ability to choose the color of clasps and crowns,
  • quick adaptation: virtually no discomfort, gum rubbing or speech changes,
  • softness, elasticity and lightness, including fastening elements,
  • absence of metal in the structure,
  • Dental D material is hypoallergenic,
  • reliable fixation in the oral cavity due to the elasticity of the material,
  • significantly smaller construction volume in comparison with acrylic and nylon analogues,
  • the strength of the material and the possibility of correction (modeling) of the prosthesis, which significantly extends its service life.

Quadrotti dentures are very convenient for daily use. Due to its softness and lightness, adaptation and further use are very comfortable. The structures are practically not felt in the mouth, and artificial teeth look very natural and natural, which is why they are recommended for dental prosthetics for children and people with hypersensitivity of the mucous membrane.

“I generally quickly got used to quadrotti. They are much more comfortable than my previous dentures. I can’t say that they look absolutely perfect in the mouth, but they are quite natural, again in comparison with other options. And one more important plus: only with them I finally stopped being afraid that false teeth would pop out at the most inopportune moment..."

Evgenia V., 56 years old, fragment of a review on the website 32top.ru

It is worth noting that the Quattro Ti company decided to distinguish itself when creating products for dental restoration: Quadrotti dentures today have various fruit flavoring additives - this will really appeal to children who have an extremely negative perception of the presence of dentures in their mouths.

Dentures provide fresh breath

When making dentures, flavorings can be added to the plastic material. It could be a vanilla flavor or chocolate notes, or even citrus fruits. Whatever option the patient chooses, all this will give his breath a pleasant aroma and get rid of the strange taste associated with the presence of a foreign structure in the mouth. However, you need to be careful with this: foreign odors can interfere with the sense of smell and be inappropriate during the period of eating food, in addition, they can cause an allergic reaction.

“Everyone praises and praises these quadrotti, but I don’t see anything special in them. I had to get used to it just like with nylon ones, I had them before. In terms of beauty, I won’t say that it is much better - the level is the same, well, maybe the Italian ones look a little more natural, they give a naturalness to the smile and a natural shine. Also, by the way, the doctor said that they won’t be very good on the lower jaw, since they still don’t cope well with heavy loads, but on top they are more ideal. That's all. So think, decide for yourself.”

Katrina33, fragment from a review on the website irecommend.ru

Of course, the Quattro Ti has its downsides. The first is the price, they have a high cost, which starts from 40 thousand rubles for prosthetics of one jaw. The second is, as mentioned above, gradual atrophy of bone tissue. But here, alas, there are no alternatives among removable devices that could prevent it.

Expert “A prosthesis made from Dental D material has a minimal number of pores, which allows the following problems to be eliminated for the entire period of operation: swelling of the structure from absorbed moisture, the presence of an unpleasant odor and the accumulation of pathogenic bacteria like staphylococci, the occurrence of destruction, color changes under the influence of coloring pigment . Naturally, the positive properties of the material will be preserved only if the patient carefully takes care of the structure and the oral cavity.” Orthopedist Andrey Rastislavovich Chernov

Disadvantages of Quattro Ti

  • dentures are not suitable for very high loads, but they, as a rule, lead to the loss of natural teeth, so the disadvantage is relative,
  • cannot be used if there are no teeth left in the oral cavity - supports in the form of living teeth are required for fixation,
  • the high cost is due to the characteristics of the material for their manufacture,
  • It is recommended to store and care for dentures using special solutions, which at the same time allows you to extend their service life.

Are there any contraindications for installation?

As for the restrictions on installing Quattro Ti prostheses, the list here will be minimal. Among the existing contraindications, experts in the field of prosthetics identify the following conditions:

  • the presence of teeth destroyed by caries and other pathological phenomena in the oral cavity requiring dental treatment - it must be carried out in advance,
  • acute inflammation of periodontal and gum tissues – also requires correction, if possible,
  • the presence of moving teeth on which it is simply impossible to attach the system - it will also wobble,
  • allergy to the material (in extremely rare cases),
  • inability to provide proper care for the prosthetic structure for any reason.

It is worth noting that the range of indications for their installation is much wider than that of other prosthetic devices. It is for this reason that the choice of patients and specialists is increasingly falling on this option of prosthetics.

"Quadrotti" are suitable for complex clinical cases

Quattro Ti, like the clasp design, is indicated for patients with periodontal diseases, and can be used as a splinting device to secure slightly loose units. But that’s not all, it is suitable for patients suffering from bruxism and malocclusions, sensitivity of the mucous membranes, mental disorders, people who engage in dangerous sports and professions. Even children are allowed to wear it. In case of any traumatic factor, bruise or blow, the structure will not cause harm.

Also, this option of prosthetics is indicated as temporary or when a person does not want to install a bridge structure and grind abutment teeth under it to fill a single defect.

Features of care

Soft systems produced under the Quattro Ti brand are very reliable and durable. But this does not mean that after installation you do not need to monitor them. However, caring for Quadrotti dentures will not cause much trouble: morning and evening - clean your teeth with a soft brush and toothpaste. It is advisable to remove the dentures from the mouth and clean them with a stream of tap water. And at least once a week it is worth soaking the structures in special antibacterial solutions in order to protect the material from destruction.

Important! To store Quadrotti prostheses in special liquids, choose a dark or matte container so that it does not allow direct sunlight to pass through, which can deform the plastic.

Acry Free

The design of the models consists of a durable frame that serves as an imitation of gums. The kit includes artificial crowns made of ceramic, zirconium or plastic.

Partial removable structures are fixed using hooks. The clamps are made from the same material as the frame. The patent for the Acry Free material belongs to the Uniflex brand. The composition is based on acrylic resins. The design is light, flexible and invisible in the oral cavity. Prostheses made from this material are compact and have a smooth surface.

The adaptation period to Acri Free takes half as long as to acrylic systems and lasts up to two months. The process of bone loss slows down by 1.5 times.

Comparison with other types of orthopedic devices

“Quadrotti” dentures provide the most uniform distribution of the chewing load, which minimizes the risk of injury to the mucous membrane. If we compare this model with the equally popular Acri-Free dentures, it is worth noting a tighter fit to the supporting teeth and gums, as well as the ability to self-balance, which ensures uniform pressure while chewing food. But Quadrotti is in no way inferior to its nylon competitors in flexibility and lightness, but is stronger and more durable, and does not stretch as much - the service life is at least 3-4 years longer.

Patient reviews

About Acri Free prostheses

“I started having serious problems with my teeth when I was a child, and now I’m using dentures. I am now 33 years old, and by this time I discovered that I had a severe allergy to metal in my mouth. My doctor suggested an inexpensive acrylic option or Akri Free. I read reviews on the Internet and settled on the second option. Of course, you had to get used to the fact that you have some kind of foreign thing in your mouth, but these are minor things compared to a toothless mouth. Now I can talk and eat with them freely, and I don’t experience any pain or discomfort. Personally, I think it’s a very good solution to the problem.”

Elizaveta E., Moscow, review from flamp.ru

About Quadrotti prostheses

“Yes, this is a real find! A nylon prosthesis cannot be compared with Quadrotti, I realized that from my own experience! The addiction is almost instant, and it looks perfect in the mouth. After this nylon horror, I now spend hours in front of the mirror with a stupid smile on my face, I can’t get enough of it. Believe me, it's worth the money! I don’t know what will happen next, but the doctor promised me that this prosthesis will last 10 years for sure.”

Antonina P., Samara, review from flamp.ru

Cost of dentures

The cost of creating and installing a prosthetic structure directly depends on the scale of prosthetics. In other words, the more teeth that need to be restored, the higher the cost of treatment will be. On average, you will have to pay about 30 thousand rubles to fix the Quadrotti prosthesis. In premium clinics and if it is necessary to restore a large number of teeth at once, the price can reach 50 thousand rubles.

You write that Quadrotti is good for everyone, but causes bone tissue atrophy. Are there options that will help avoid this defect if there are no teeth left in the mouth?

Artem Valerievich (06/29/2019 at 09:59) Reply to comment

    Dear Artem Valerievich, the problem of bone tissue atrophy can be solved only by installing implants. For example, there are implantation methods that today allow you to get a new smile in just a few days and are called one-stage protocols with immediate loading of the prosthesis. In case of multiple edentia, they comprehensively allow you to restore teeth. For example, all-on-3 or all-on-4. The cost of treatment will start from 280 thousand rubles - but you will no longer have problems, while the pullers will have to be constantly adjusted and changed. And remember, the greater the bone atrophy - it increases in direct proportion to the duration of wearing “pullers”, even such advanced ones as “Quadrotti”, the greater the number of implants for successful rehabilitation will have to be implanted later. You may not get away with three or four, but you will have to resort, for example, to prosthetics on 6 or even 10-14 implants at the same time.
