Clasp prosthesis with clasp fixation. Clasp prosthesis on clasps is a great alternative to modern implants. Advantages and disadvantages of clasp prosthetics on implants

Removable prosthetics on clasps is one of the most affordable and effective ways replacement of lost teeth. When using this method, the chewing load is distributed evenly over the entire surface of the jaw, which is close to the physiological variant. In addition, this strong monolithic system is often used as a splinting ligament to help immobilize mobile roots.

FEATURES OF THE DEVICE OF THE BUGEL PROSTHESIS ON THE CLAMMER

The design includes:

1. Acrylic base with artificial gums and crowns.
2. Metal arc - byugel.
3. Fasteners.

The classification of this type of prosthetics is based on the type of fixing parts. Most often, in clasp products, special hooks are installed as fasteners. They securely hold the plastic “gingival” bed with crowns on bearing teeth. These locking elements are made of neutral metal alloys or stainless steel. Such hook-holders are called clasps.

Another type of fastening used in modern clasp prostheses is attachments, or locks. They represent a fundamentally different fixation technology.

INDICATIONS FOR INSTALLATION

The use of the clasp system is indicated for the loss of several teeth, loosening of the remaining ones, the presence of a deep bite and bruxism (as contraindications to other types of prosthetics). Direct indication: unilateral and bilateral end defect.

ADVANTAGES OF PROSTHESES ON CLAMMER

The main advantages: the safety of the abutment teeth and a simpler fastening system (compared to locks). Additional:

1. Ease of use. There is no bulky plastic jumper in the sky area.
2. Functionality. The taste and touch of food in the oral cavity are preserved.
3. Security. The degradation of tissues in places where there are no teeth is suspended.
4. Reliability. The prosthesis is firmly fixed.
5. Durability. The service life is 2 times longer than that of other removable structures.

CARE RULES

Clasp prosthesis on clasps will last at least 5-7 years with proper care. For cleaning, it is enough to use toothpaste and a not too soft brush twice a day, and then gently rinse your mouth with plain water.

WE INVITE YOU TO THE DENTALUX-M CLINIC!

We consider simplicity and rationality to be the main advantage of this technique. The hook design is modeled and cast at the same time, and this reduces the labor cost. At the same time, it is possible to keep the abutment teeth intact.

Come to us for a consultation. An orthopedic dentist will tell you in more detail about the technology of prosthetics on clasps and the possibility of its application in your case. Our specialists analyze the indications, features and financial capabilities of the patient and only after that recommend the method that will be most appropriate for him.

Clasp prosthetics is a popular method of restoring the dentition, which uses removable dentures with clasps (hooks) and attachments (locks).

Constructions with clasps are at least two times cheaper, while they are durable, strong and reliable, do not require special care. They are also considered a budget alternative to implants and a reliable alternative to bridges and lamellar prostheses.

Features of clasp prostheses on hooks

The design consists of the following elements:

• arc (in German - bugel);
• artificial teeth (attached to the arc);
• basis (gingiva simulator);
• clasps (hooks that fix the prosthesis on the abutment teeth).

Types of clasp prostheses with clamp fixation

According to the design and purpose of the structure, two types of prostheses are distinguished - conventional and splinting.

Ordinary clasp prostheses with clasps

They are recommended in cases where it is not possible to place implants and there are teeth left in the mouth that can be used as a support for the prosthesis. The design allows you to eliminate such defects in the dentition as:

• the absence of three or more teeth in a row (anterior, lateral, on one side of the jaw or / and from different);
• end defects of the dentition (when there are no last teeth).

Splinting clasp prostheses on hooks

They differ from ordinary ones in that in their design they have special retainers (processes on the arc) for supporting teeth. They are used to restore the dentition in patients suffering from:

• pathological mobility of teeth (the prosthesis fixes loose teeth and protects them from excessive chewing load);
• malocclusion (the design keeps the teeth in the correct position, thereby correcting the abnormal closing of the jaws);
• increased abrasion of the upper teeth (the prosthesis covers the chewing surface of worn teeth, making them higher and protecting them from further abrasion).

Splinting clasp prosthesis

Depending on the materials, there are 2 types of clasp prostheses:

1. Prostheses containing metal. The arc and clasps (and sometimes the base frame) for such structures are made of chrome-cobalt or gold-platinum alloy.
2. Metal-free structures. The so-called Quattro Ti prostheses with nylon clasps and a base made of a mixture of nylon and hypoallergenic plastic.

Manufacturing and installation steps

Prosthetics with clasp prostheses includes two main stages - clinical and laboratory. From the moment you contact the clinic to the restoration of the dentition, the following stages go through:

1. Survey. The doctor draws up a plan for prosthetics, makes a conclusion about the state of health of the oral cavity and, if necessary, sends the patient for the treatment of caries and / or periodontal disease.
2. Taking an impression of both jaws.
3. Making a prosthesis in the laboratory. Structures with metal elements are made by casting methods, plastic ones are produced with exposure to high temperatures.
4. An example of the finished design. If necessary, a correction is made.
5. Installation of a prosthesis.

On average, the clinical and laboratory stages of prosthetics take one week.

Price

The average price for the manufacture and installation of a conventional clasp prosthesis with clasps is 35,000 rubles. Splinting structures, as a rule, are a little more expensive - 40,000 rubles.

How to care for a prosthesis?

Clasp dentures with clasps should be cleaned at least twice a day, and preferably after each meal. Hygiene measures include:

• rinsing the structure under running water after eating;
brushing and low-abrasive paste at least twice a day;
• daily disinfection (soaking in solutions of disinfectant tablets Corega, Lacalut, Efferdent, President, Dentipur, Dontodent, etc.);
• professional cleaning (performed by a dentist to remove hard deposits).

It is advisable not to remove the prosthesis at night and stay in it all the time. Once every six months, you need to visit the dentist to rebase the structure (corrections for even distribution of the masticatory load).

The result of prosthetics depends not only on the quality of the prosthesis, but also on the qualifications and skills of the orthopedic dentist. Our website contains an up-to-date list of clinics that effectively carry out the restoration of the dentition using clasp structures.

The use of most prostheses requires a secure fit. A variety of gels and ointments applied to the gums do not provide proper fixation. Therefore, clasp systems come to the rescue.

What is a clammer?

Clammer is integral part removable prosthesis, outwardly similar to specific hooks. Its purpose is to hold the denture. The fixing structure itself is assembled from several parts:

1. Occlusal overlay - contributes to the distribution of the load on the supporting dental units.
2. The body is a fixed area located closer to the upper pole of the chewing element. Connects all components.
3. Shoulder - gives a springy effect when the denture is displaced, covers the zone of the dental crown. It contains a support (prevents displacement to the side, gives rigidity) and a holding part (fixing action).
4. Process - connects the fixing part with the prosthesis, often covered with a base or crowns.

The task of the clasps is to fix the prosthesis

To use the clasp system, you must have your own chewing elements that will serve as a support. Primary requirements:

1. Sustainability.
2. Functional relationship to the opposite unit of the other jaw arch. The fixative ingredients will raise the bite when natural close contact occurs during chewing or clenching of the jaws.
3. Classic anatomical shape. Selection with a non-standard configuration is quite risky and impractical.
4. Complete healing.

The selection of a clasp system is not an easy task for a dentist. The installation is considered successful if:

1. The bite does not increase.
2. The rotational movements of the prosthesis are excluded.
3. The load is evenly distributed among all support units.
4. The components of the fixator are practically invisible or completely invisible.

Clasps for dentures are made of wire or by casting.

The condition for strong fastening is the presence of strong teeth-supports

Types and classification

The variety of problems associated with the loss of teeth leads to the emergence of a large number of options for clasp structures and classifications.

The functions of the system are:

1. Supporting - used on molars and canines, require the use of locks, rarely used in isolation.
2. Retaining - sometimes lead to subsidence of the prosthesis.
3. Combined, or support-holding.

According to the choice of material, the clamps are:

1. Metallic (metal alloys).
2. Acrylic (plastic).

This is what plastic clasps look like

Types by place of application:

1. Gingival.
2. For the dentition.
3. Combined.

According to the type of coverage of the element: single-arm, two-arm, T-shaped, cross-over, double, multi-link.

According to the mobility of attachment to the prosthesis:

1. Movable.
2. Rigid.
3. With springy effect.

Mounting configuration:

1. Point.
2. Linear.
3. Planar.

The clasps hold the prosthesis in place, preventing it from shifting onto the mucosa

Clasp functions

The main purpose of clasp-type retainers is retention - holding the prosthesis in place during use. The fixators are a support that does not allow the structure to move in the direction of the mucosa, counteract the force of lateral pressure and, to a small extent, the load along the vertical axis.

The shoulders contribute to the clamping of the support unit. Together, these features provide a secure fit for the denture, minimizing inconvenience and improving quality of life.

Ney system

Methods were introduced into orthodontics by Ney in the middle of the last century. These are classic support-holding clamps. They contain a process, two shoulder elements and an occlusal type overlay.

To minimize the fracture of the fastener, the sections located closer to the base were made thicker and stronger, while the distant sections gradually become thinner, the product takes the form of a horn.

Ney's devices include the following options:

1. Single shoulder.
2. Forked Roach.
3. Akkera with two shoulders.
4. Ring one-shoulder.
5. Combined.

General characteristics include practicality, wear resistance, high aesthetic performance.

Klammer Akkera

One of the most effective and affordable fasteners. It is installed on the molars in the absence of one or more chewing elements and intact supports. Simple in design, securely holds against displacement.

Different kinds clasps

Bonville

A modification of the Akker retainer is the Bonville clasp. This type is based on two overlays of the occlusal type. They are placed in an anatomical gap located on the chewing surface of the supporting tooth. Additionally, two shoulders are used.

The purpose of the design is to hold and give stability in case of unilateral defects in the dentition. The peculiarity of the structure prevents food from entering the interdental spaces, reducing the risk of inflammatory processes in the oral cavity.

Roach

It is a rod type of fixer. It has a springy effect due to the long shoulders.

The advantages include:

• uniform distribution of pressure,
• aesthetics.
• choice retainer in case of short teeth,
• good holding characteristics.

1. Limited in the choice of material, this type is made exclusively of chromium or nickel. Therefore, it is not recommended for patients with metal allergies.
2. It is not used for anatomical features of the jaw arch and teeth, when the gums of the upper jaw are exposed when smiling

Jackson

Jackson's clasp is a combined design of a cross-over type. It has the shape of a loop, the part that is located in the interdental spaces is considered to be the reference. It is made from wire or by casting.

Clammer Adams

Versatile and durable mount. It is able to be fixed both on single chewing elements and on a full dentition. Adams are installed on the first premolars and molars.

Clammer Adams

swept

More often this option used to strengthen orthodontic plates. For installation, the interdental space is used, located below the line of the equator of the tooth.

Schwartz

A kind of arrow-shaped fastening of a point configuration, it can be one- and two-link. This type is widely used in orthodontic practice due to its high fixing capacity. The product is only wire.

Multi-link clasps

Consists of shoulder processes connected to each other. Such a fixative is adjacent to each tooth, shaped like a semi-oval. It is made in the form:

1. A wide strip is a variation of the Cross Shredder.
2. The narrow stripe is a variation of the Kennedy.

Multi-link clasps

They play the role of combining parts of the denture and fixing them.

The choice of clasp system in each case is individual. The volume of prosthetics and the initial state of the dentition is taken as the basis for preference.

Every patient who comes to the dentist wants to get a durable and comfortable prosthesis. This is especially true in cases where we are talking about removable structures. Byugel prosthetics will allow not to lose the beauty of the dentition even in the most difficult cases. Such designs are removed and suitable if partial restoration of the tooth is required. They do not interfere with eating and are quite comfortable to wear.

Types of clasp structures

Clasp structures are classified according to the fixation system into:

• clasp;
• castle;
• on telescopic crowns.

The design of clasp prostheses includes:

• base, which is made of acrylic plastic. Artificial teeth are attached to it;
• Metal frame made of cobolt-chromium alloy;
• prosthesis fixation system.

Indications for use

Clasp prosthesis designs are used by patients who have the following disadvantages:

• absence of lateral or anterior teeth;
• the presence of weakness of enamel or increased abrasion of teeth;
• missing one or more teeth. With the help of prostheses, it is possible to close several gaps or restore missing teeth nearby;
• tooth mobility in periodontitis. Dentures securely fix the teeth in a certain position, after which the therapeutic treatment of the disease is carried out. With this treatment, the ligaments are restored.

You should know that to restore the extreme teeth and in the presence of complete adentia (absence of all teeth in the oral cavity), clasp structures are not used. In these cases, the design cannot be fixed. but Fixing problem can be solved by installing implants. They will allow you to fix the design in the oral cavity even in the absence of natural teeth.

Clasp prosthesis on clasps

Designs with such a mount are the most popular, as they are quite affordable from an economic point of view. Clasps are a continuation of the base of the entire structure (byugel). They are located at the base of the supporting teeth. They tightly wrap around the tooth, securely and firmly fixed. For enamel, they are completely safe. Clasps made of metal and cast together with the frame, for each patient individually.

Clasp structures on clasps, in addition to the low price, have one more advantage. They allow you to evenly distribute the load not only on the supporting teeth, but also on the entire bone.

The disadvantage of fastening on clasps is the gradual loosening of the abutment tooth. This happens for a number of reasons: improper use of the prosthesis, due to excessive loads, or as the prosthesis fails. In some cases clasps are not aesthetic enough, since the hooks are located in front and, therefore, can be seen.

Clasp prostheses on telescopic crowns

This is one of the most convenient types of modern removable prosthetics. Of all castle structures, prostheses on telescopic crowns are the most reliable. They got this name because the docking of the components has the principle of the structure of a telescope. You can put such a structure both on teeth and on implants.

For the elderly, telescopic prostheses are good choice. They not only very convenient to use but they can be adjusted at any time. Clasp structures on telescopic crowns can replace big number teeth.

Types of crowns for telescopic fixation

Cone crowns. They are less sensitive to wear and manufacturing errors. The stronger the taper of the crowns, the less force is applied to separate them. Conical telescopic crown not capable of warping and jamming. However, with a weak bond from the tongue or sticky food, such crowns may come apart.

Cylindrical crowns. They are used only on the teeth of patients suffering from intact periodontal disease. They have parallel walls that slide over each other and hardly provide traction. Such designs are used infrequently due to the fact that they are difficult to manufacture.

What are prostheses on telescopic crowns made of?

Clasp structures with a telescopic fixation system are made from special hypoallergenic dental alloys that are safe for health and do not oxidize in the oral cavity.

The fixed and removable parts of the structure are made, if possible, from the same alloy.

Galvanic technology is more rational. The main part can be made from an alloy of base metals (zirconium dioxide), and the outer part can be made from gilding.

Prostheses made of gold are more accurate, but also more expensive. Therefore, base metal alloys are used as an alternative.

Prosthesis design

The prosthesis itself is a removable part of the structure. It can be bridge-like or clasp. The metal crown is mounted securely in it.

A cap made of metal, which in appearance resembles a thimble, is firmly fixed on the abutment tooth and is a non-removable part of the structure. It is attached to the supporting tooth on the basis of the implant or with the help of cement. Reliable and durable fixation occurs when the removable part of the prosthesis is put on the non-removable part. If necessary, it can be easily removed.

Clasp prostheses have their advantages and disadvantages.

Advantages:

• securely and firmly held in the mouth;
• it is easy to take care of artificial teeth, since when the structure is removed, the interdental spaces are easily accessible;
• invisible to others;
• With further loss of teeth, the design can be quite easily transformed;
• such prostheses are very durable;
• do not affect diction;
• chewing pressure is distributed specifically to the supporting teeth;

Disadvantages:

• in connection with double dental crowns, a large space is required;
• very expensive.

Clasp prostheses with locks

It's comfortable, but rather expensive method of fixation. One part of the attachment is located inside the prosthesis, and the second part is inside the abutment tooth.

The advantage of the lock fastening is the appearance, since design is completely invisible.. Such structures are easily repaired and updated. In order not to damage the fasteners, it is not advisable to constantly remove the prostheses.

The service life of clasp prostheses and their care

Depending on the care, such structures can last more than five years. Therefore, it is very important to comply with a number of requirements:

• brush artificial teeth every day;
• after eating, they should be removed and rinsed with tap water;
• from time to time it is necessary to soak in special solutions;

These actions will be quite enough to extend the life of new artificial teeth.

Despite some shortcomings (addiction, aesthetics), clasp prostheses are considered the most reliable option removable prosthetics.
