Telescopic prostheses are deservedly considered the most comfortable type of modern removable prosthetics. Among all the castle structures, such a device is the most reliable. Telescopic prostheses as an alternative to dental implants have been used for a very long time and are in great demand in view of maximum convenience and safety.
They got their name due to the fact that the joint of structural parts is built on the principle of a telescope. A telescoping system can be installed using both teeth and implants.
Such prostheses are considered an excellent option for elderly patients. The designs are very convenient to use and can be adjusted if other teeth are lost. A removable prosthesis with a telescopic fixation system can replace a large number of lost crowns.
The manufacture of such a structure is an extremely complex process. For high-quality manufacturing, the participation of a qualified dental technician, the availability of reliable materials and special devices is necessary. Even minimal violations of production technology or the use of poor raw materials can very negatively affect the final result.
How is the design
Removable telescopic prostheses consist of two elements.
- Fixed part. It is a specific cap made of metal, which is firmly fixed to the supporting surface - a tooth or implant. Visually, it resembles a simple thimble. The cap is mounted on the supporting surface using cement.
- Removable part. This is the prosthesis itself, it can be bridge-like or clasp. A metal ceramic crown is securely mounted in it - it remains there forever and cannot be replaced.
At the time of connection of the removable and non-removable component, the structure is firmly fixed. A modern telescopic prosthesis makes it possible to reliably fix crowns on the abutment teeth. In addition, if necessary, the structure can be easily removed.
Varieties
There are two types of telescopic prostheses:
The latter variety is considered less susceptible to wear and errors made during the manufacturing process.
The more pronounced the conicity of the crowns, the less effort is required to separate them. Such prostheses cannot warp and jam. But the disadvantage of loose fixation lies in the fact that the prosthesis can easily detach due to the pressure of the tongue or sticky products, such as sweets.
The use of conical crowns is advisable in all situations where the installation of removable structures is required.
Cylindrical prostheses have parallel walls that slide relative to each other and hardly provide a secure fit. They are used exclusively on teeth with an intact periodontium. Due to production difficulties, such systems are extremely rare.
Materials used
Telescopic crowns and dentures are made on the basis of special dental alloys.
- Fixed and removable components of the system are made, if possible, of the same material.
- The alloys used for the manufacture of prostheses are hypoallergenic and absolutely safe for health. Such structures are not able to oxidize while in the oral cavity.
- Excellent replacement for gold crowns are considered alloys of base metals. In the manufacture of a structure made of gold, it turns out to be more accurate, but also extremely expensive.
- From a technical point of view, the optimal solution is the use of galvanic technology. With its help, most of the design can be made from alloys of base metals or zirconium dioxide, and the outer facade from gilding. This manufacturing technology is considered high-tech.
Indications for use
It is advisable to install telescopic prostheses when:
- minimum number of natural teeth;
- the patient’s desire to have a smile that is no different from a natural one;
- poor condition of the remaining teeth and a high probability of their imminent loss;
- desire for the most reliable fixation of the structure in the oral cavity.
Features of telescopic dentures
The main disadvantages of such structures are:
- relative high cost;
- the need for a large amount of free space due to the use of double crowns.
But the advantages of telescopic prostheses are much greater. The main advantages include:
- reliable fixation in the oral cavity;
- esthetic appearance - the design is completely invisible to people around;
- the possibility of changing the system with tooth loss in the future;
- high strength of the prosthesis;
- lack of impact on normal diction;
- the availability of dental gaps when the structure is removed, which makes it possible to fully care for the oral cavity;
- the distribution of chewing pressure on the supporting surfaces, which positively affects the periodontium.
Cost
The price of telescopic prostheses primarily depends on what material is used in their manufacture. An important role in their cost is also played by the number of teeth on which the system will be installed. The high price of such designs is explained by the fixation of double crowns for each tooth.
The approximate cost of telescopic prostheses is in the range of 20-24 thousand rubles. It is noteworthy that the price of crowns and clasp designs is not much different.
Life time
During the period of wear of the structure - after about 3-4 years, the crowns lose their original fixing force and become a little looser. In general, the service life of telescopic prostheses ranges from about three to ten years. To extend this period, you should correctly use the design, systematically undergo dental examinations and timely perform the necessary correction.
Care
There are several rules that must be followed when using telescopic crowns:
- you can apply the design around the clock;
- It is only necessary to remove the prosthesis before carrying out hygiene measures;
- there is no need to place the prosthesis in water, leaving it there for the night;
- wear and remove crowns should be exclusively in front of the mirror to prevent all kinds of defects;
- it is necessary to undergo examinations, since the prosthesis requires constant monitoring of its functions by the dentist.
Alternative
For any patient, the selection of the type of prosthetics is always quite a challenge. But be that as it may, to make the right decision it is very important to know about all the existing varieties of designs.
- Dental implantation. An excellent alternative to any kind of removable prosthetics, including telescopic.
- Conventional removable designs. They significantly lose telescopic prostheses in the reliability of fixation and ease of use. In some cases, to mount removable structures, it is necessary to remove the patient's teeth.
- Nylon systems. Such designs are also inferior to telescopic crowns in terms of their service life. So, if a tooth is lost under a nylon prosthesis, it will no longer be possible to change and correct it. So such a solution certainly will not work for patients who are not sure about the further preservation of the remaining teeth.
- Clasp constructions with micro locks. Such a system is considered a good alternative to telescopic crowns. However, they cannot be produced with too few teeth remaining in the patient.
Reviews
Responses about dentures with telescopic fixation systems are mostly positive. Many patients primarily note the ease of use of such structures and their reliability. Such systems remain invisible to surrounding people and look quite aesthetically pleasing. It is almost impossible to distinguish the telescopic structure from natural teeth with the naked eye.
In addition, most patients talk about the maximum comfort they experience while wearing such crowns. Thanks to the convenience, according to users, getting used to such a prosthesis is easy and fast.
Speaking of comparative evaluations, reviews are often found in which patients share their experience in using similar designs that lose in their characteristics to telescopic crowns. For example, often people prefer such prostheses after using clasp and acrylic systems, mentioning the inconvenience of the latter. By the way, such crowns are installed much longer. According to patients with telescopic structures, one can completely forget about their presence in the mouth. Such a product will help any person to feel young and attractive again.
Another advantage of telescopic prostheses, according to users, is the ease of care for them. On the recommendation of patients, special tablets can be used that greatly simplify hygiene procedures. To remove and put on crowns is also quite easy and simple, it does not take much time.
As for the negative reviews, almost all of them are devoted to the too high cost of telescopic structures. Although, at the same time, many patients believe that such an impressive price is justified by the unsurpassed quality and comfort of the crowns. In their opinion, a snow-white attractive smile, obtained with the help of telescopic prostheses, is definitely worth it.
