Description, advantages and disadvantages of clasp prostheses on clasps and telescopic crowns, dental advice

Every patient who comes to the dentist wants to get a durable and comfortable prosthesis.This is especially true when it comes to removable structures.Clasp prosthetics will not lose the beauty of the dentition, even in the most difficult cases.Such designs are removed and suitable for partial restoration of the tooth.They do not interfere with food and are quite comfortable to wear.

Types of scaffold constructions

Clasp structures are classified by the locking system on:

• clamping;
• lock;
• on telescopic crowns.

The construction of the denture prosthesis includes:

• basis, which is made of acrylic plastic.Artificial teeth are attached to it;
• Metal frame made of a kobolt-chrome alloy;
• fixation system for the prosthesis.

Indications for use

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

• no lateral or anterior teeth;
• presence of weakness of enamel or increased tooth erosion;
• absence of one or more teeth.With the help of prostheses it is possible to close several crevices or restore missing teeth next to them;
• teeth mobility during periodontitis.Prostheses securely fix teeth in a certain position, after which the therapeutic treatment of the disease is carried out.With this treatment, ligaments are restored.

It should be noted that for the restoration of extreme teeth and in the presence of complete adentia( absence of all teeth in the oral cavity), clasp designs are not used.In these cases, the construction can not be fixed.However, can solve the fixation problem by installing implants.They will allow to fix the design in the oral cavity even in the absence of natural teeth.

Clasp prosthesis on clasps

The structures with this fastening are the most popular, since they are quite affordable from an economic point of view.Clammers are the continuation of the base of the entire structure( clasp).They are located at the base of the supporting teeth.They tightly grasp the tooth, securely and firmly fixed.For enamel they are completely safe.Cladders are made of metal and are cast together with the frame, for each patient individually.

Clasp constructions on clamps, except for the low price have one more advantage.They allow you to evenly distribute the load not only to the supporting teeth, but also to the entire bone.

The disadvantage of fastening on the clamps is the gradual loosening of the supporting tooth.This happens for a number of reasons: improper operation of the prosthesis, due to excessive loads or as the prosthesis breaks down.In some cases, clasps are not aesthetically pleasing to the , since the hooks are located in front and, therefore, can be seen.

Clasp prosthesis on telescopic crowns

This is one of the most convenient types of modern removable prosthetics.Of all the lock structures, the prosthesis on the telescopic crowns is the most reliable .This name they received because the docking of components has the principle of the structure of the telescope.You can put such a design on both teeth and implants.

Telescopic prostheses are a good choice for the elderly.They are not only very easy to use , but they can be corrected at any time.Clasp designs on telescopic crowns can replace a large number of teeth.

Types of crowns for telescopic fixation

Cone crowns .They are less sensitive to wear and manufacturing errors.The stronger the conicity of the crowns, the less effort is used to separate them.Cone telescopic crown is not capable of skewing and jamming .However, with a weak grip on the tongue or sticky food, such crowns can disconnect.

Cylindrical crowns .They are used only on the teeth of patients who suffer from intact periodontitis.They have parallel walls sliding along each other and with difficulty providing traction force.Such designs are used infrequently due to the fact that they are difficult to manufacture.

Prostheses made on telescopic crowns

Clasp designs with telescopic fixation system made of special hypoallergenic dental alloys are produced, which are safe for health and do not oxidize in the oral cavity.

Non-detachable and removable parts of the structure are manufactured, if possible, from the same alloy.

Galvanic technology is more rational.Of the base metal alloy( zirconia), the main part can be made, and the outer part from the gilding.

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

Construction of the prosthesis

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

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

Clasp dentures have their advantages and disadvantages.

Advantages:

• reliably and firmly held in the mouth;
• is easy to care for artificial teeth, as with the removed design, interdental spaces are easily accessible;
• are invisible to others;
• With further tooth loss, the structure can be easily converted;
• such prostheses are very strong;
• does not affect the diction;
• the chewing pressure is distributed specifically on the supporting teeth;

Disadvantages:

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

Clasp prosthesis on locks

This is comfortable, but is an expensive way to fix .One part of the fixation is located inside the prosthesis, and the second - inside the supporting tooth.

The advantage of locking is the appearance, since the design is completely invisible .Such structures are easily repaired and updated.In order not to damage the fixing elements, it is not advisable to permanently remove the prosthesis.

Life of clasp prostheses and care for them

Depending on the care, these 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 sufficient to prolong the life of new artificial teeth.

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