Prosthetics with clasp prostheses in the modern world is gaining more and more popularity. On the one hand, this is due to the fact that the production of this type of prosthesis has become better. For their manufacture, new modern materials are used, thanks to which the entire design of prostheses becomes light, comfortable and invisible to other people. This method of prosthetics is very hygienic, wearing prostheses does not cause discomfort to patients. It is these qualities that make the procedure popular. In the article, we will take a closer look at the stages of manufacturing a clasp prosthesis, its advantages, types, cost and patient reviews.
Clasp prosthesis: what is it?
The false jaw is a phrase that is a sentence for many people. A complex, uncomfortable design immediately comes to mind, which, being in the mouth, causes more harm and discomfort than good. In addition, prices for removable dentures are quite high, which also repels potential customers.
Fortunately, modern science and medicine do not stand still. Right now inDentists successfully practice the use of clasp prostheses. They are a variety of all removable dentures and have many positive qualities.
The technology for manufacturing a clasp prosthesis is fundamentally new, it has several important steps, the sequence of which must be observed.
The main difference between a clasp prosthesis and an acrylic construction is a metal frame or arc. Due to this, the thickness of the plastic base of the prosthesis becomes smaller, and it is more comfortable to wear.
All models of such prostheses have a clasp frame, an acrylic plastic base (artificial teeth are placed on it) and special devices that will help fix the prosthesis in the mouth. The metal arch, which is a distinctive feature of the clasp prosthesis, performs the main fixing function.
Manufacture of metal frames is also an important stage for high-quality prosthetics.
The frame for the prosthesis can be brazed and cast. The first is very simple to make, but it is inconvenient to wear. Now such frameworks are used less and less, since patient comfort is one of the main qualities that a set of false teeth should have.
The only requirement for patients is a few stable abutments on which crowns can be attached.
The following materials are used to make the frame:
- Stainless steel.
- Gold-platinum alloy.
- Cob alt chrome alloy.
It should be noted that clasp prostheses do not affect diction in any way, which is also theirundeniable advantage.
Types of clasp prostheses
The main feature by which clasp prostheses are classified is the method of fixation in the oral cavity.
- Clamp fixation. This is the most common option and the cheapest. Clasps are special hooks that are put on strong abutment teeth. As a rule, with this method of fixation, the abutment does not need to be further processed or turned.
- Lock fastening. Instead of clasps with this method of fixation, micro-locks are used. One part of such a lock is attached directly to the prosthesis, and the other to the crown, which is put on the abutment tooth. This type of fastening is very convenient, looks aesthetically pleasing and is less noticeable to people around. Lock fastening is considered more reliable than clamp fixation. And the price is a little higher. The main disadvantage of this fastening of prostheses is that the abutment teeth must be ground before putting on the crown. And the turning process is irreversible.
- Telescopic crown. This method of fastening the byugel is the most convenient and aesthetic. But only a highly qualified dentist can carry out such prosthetics, as this is a long and complicated process. The telescopic crown consists of two interacting parts. The fixed part is a crown, which is fixed on a previously ground abutment tooth. The removable part is attached to the prosthesis and during its fixation is put on top of the supporting crown.
- Splinting prosthesis. In this way fixmobile teeth in periodontal disease. To fix on the inside, a metal plate is installed, which is curved in the shape of the abutment tooth.
Benefits of clasp dentures
- Strength. Ordinary models break quite often, and after repair they already sit loosely in the mouth. Because of this, there is discomfort, and even pain. Clasp prostheses do not have such a problem due to the lightweight metal frame.
- Clip dentures take up less space in the mouth than traditional models. That is why during a conversation and eating there is no inconvenience, and the patient quickly gets used to the prosthesis.
- When eating, the load is distributed not only on the gums and mucous membranes, but also on the supporting teeth. Thanks to this, the chewing process becomes more efficient and there is no pain.
- Thanks to the clasp prosthesis, the palate in the mouth remains open, which makes the wearing process more comfortable and does not affect diction.
Components of a clasp prosthesis
There are the following main elements of the prosthesis:
- Metal frame, or arc, which is necessary to connect all the elements of the prosthesis into a single structure.
- Part of the saddle-shaped structure on which artificial teeth are attached.
- Special devices for high-quality fixation of the prosthesis.
The clasp prosthesis does not have any complex intricate parts, making the wearing of such false teeth very easy and comfortable. What are the stagesmaking a clasp prosthesis, consider further.
What material is used for clasp prosthetics?
For the manufacture of clasp prostheses, new modern materials are used. Thanks to this, their quality is improved, and, accordingly, their popularity among patients is growing.
Metal and non-metallic denture material can be used. In the first case, stainless steel or metal alloys are used, in the second, plastic.
Today, in modern dentistry, prostheses with a one-piece cast construction are increasingly being used. And as for soldered prostheses, they are used in practice less and less.
Bugel prostheses with a monolithic frame are considered by dentists to be the best.
The main stages in the manufacture of clasp prostheses
There are the following steps for making a clasp prosthesis:
- Clinical (manufacturing).
- Laboratory.
- Clinical (Prosthetics).
Next, we will consider in detail all the stages of manufacturing a clasp prosthesis.
Detailed description of the clinical stage
The patient must visit the dentist several times.
- First, a comprehensive examination is carried out and an individual treatment plan is drawn up.
- Then, supporting teeth are selected, examined, treated and ground if necessary (if locking and telescopic models are used). The choice of supporting teeth is a very important step, as they may not withstand the load when wearing a prosthesis and there is a risk of losing them.
- After that, an impression of the teeth is made. For high-quality manufacturing of the prosthesis, two impressions are needed.
- When the impression of the teeth is ready, a model of the prosthesis is made from it.
- Then it is necessary to try it on and adjust, taking into account the results of the fitting.
- When all the steps are completed, the denture is finally installed in the patient's mouth.
Detailed description of the laboratory stage of manufacturing the prosthesis
- The first step is to make a diagnostic model. For this, durable plaster is used, thanks to which it is possible to make a model that is suitable individually for each client. At this stage, all the details of the structure of the patient's oral cavity are taken into account.
- At the second stage, you need to determine the nature of the bite, as well as study the location of the lower and upper jaws in three perpendicular planes.
- Next, you should carefully examine the supporting teeth and determine the level of load that they can withstand.
- Next, a graphic image of the clasp prosthesis, its drawing, is applied to the resulting diagnostic model.
- Then, on the same plaster model, the process of turning the selected supporting teeth is modeled, that is, a control preparation is carried out. This is how the process of turning natural abutment teeth will then be carried out.
- According to the drawings on the diagnostic wax model, a model of the future prosthesis frame is formed.
-
Using the resulting wax model, the frame of the clasp prosthesis is cast. blankwax is removed from the plaster model, placed in a refractory mold. There, under the influence of temperature, wax is melted and acrylic plastic is poured in instead.
The casting can be done without removing the wax blank from the diagnostic model. In this way, it is possible to avoid possible deformation of the wax workpiece, and the finished structure will be more accurate. Wax is removed from the resulting frame, it is polished and polished. Then try it on in the patient's mouth.
- At this stage, artificial teeth are installed on wax rollers.
- Then the resulting wax structure is placed in a plaster mold, the wax is melted and removed from there, and acrylic plastic is poured in its place. Thus, the metal and plastic parts of the clasp prosthesis are connected.
- At the final stage, the finished prosthesis is handed over to the dentist for installation in the patient's oral cavity.
Technologies for the manufacture of solid cast clasp prostheses
Properly making a clasp prosthesis is possible only if there is a special laboratory. Let's take a closer look at two methods of manufacturing a structure:
- In the first method, the structure is cast by removing the blank from the plaster model. The workpiece is placed in a refractory mask, where the wax is smelted, and molten metal is placed in its place.
- In the second method, the blank is not removed from the plaster model. Thus, the future prosthesis is not deformed, and wearing it will be more comfortable.
Cast clasp prostheses are very light andare easy to manufacture, so the patient does not need additional time to get used to them. They are immediately comfortable in the oral cavity and do not cause inconvenience.
How to properly care for a prosthesis?
Care for a clasp prosthesis in the same way as for real teeth. To carry out hygienic treatment of the structure, it must be removed from the mouth. But at night, the prosthesis does not need to be removed. Proper care of the prosthesis is necessary in order to prevent the development of germs under it. Before removing the structure from the oral cavity, be sure to rinse your mouth with water to wash out food debris. Do not neglect the care of the prosthesis, in no case think that if the teeth are not real, then you can do nothing and not take care of them in any way. To store the prosthesis, it does not need to be placed in a glass of water.
How long will clasp dentures last?
If you follow all the rules for using and caring for a denture, then it will last at least 5 years, or even more.
It should be noted that under the action of the clasp design, the gums and bone tissue are less susceptible to atrophy and deformation than when using plastic prostheses.
How much does clasp prosthesis cost?
Not all people can afford removable dentures. Prices for such designs are very diverse and depend on many factors. The cost of prosthetics is influenced by:
- Difficulty in making a prosthesis.
- Materials that are needed to make the structure.
- Type of attachment of the prosthesisto the teeth. Fastening with locks will cost more, since the price of the locks and crowns themselves is included in the prosthetics.
- Services for preparing teeth for prosthetics may also be included in the price (dental treatment, taking impressions, etc.).
The cheapest will be a regular clasp prosthesis. Its price is 15 thousand rubles. A complex and splinting clasp prosthesis will cost you 5 thousand more. But for the construction on the locks you will have to pay from 35 to 50 thousand rubles.
Despite the considerable cost of clasp prosthetics, its popularity is growing very quickly due to its quality, convenience and long service life.
Patient feedback on clasp prosthetics
The clasp dentures received a number of positive feedback from patients. First of all, people note the long service life of such a prosthesis. Many patients consider convenience and comfort when wearing a structure to be an important criterion. In addition, the prosthesis does not affect diction in any way and does not fall out of the mouth, as can happen with conventional models.
Conclusion
So, in the article we examined in detail the clasp prosthesis: what it is, what it is, its advantages, manufacturing steps and patient reviews. All people who had to use clasp prosthetics were satisfied and can safely recommend such prostheses to their friends.
