More recently, a visit to the dentist with his forceps and a drill was perceived almost as a call to the Gestapo. But now doctors can easily cope with the pain and the patients' fears have shifted towards the wallet. The beauty and usefulness of the replacement of teeth go parallel course with financial opportunities and advertising a photo.
Even the simplest case: when you need to insert only one tooth can provide a painful choice - when you do not want either one or the other. So the operation that was avoided is the best, and for this the only way remains: it is very attentive to its teeth. But still: if there is already a problem place and it is between two healthy teeth, then there are three options (with the exception of the simplest one: the usual crown).

The pin stud
This case implies that only the root of the tooth remains, and it is quite healthy. Here, a lot depends on the professional inclinations of the doctor: if he initially sought to maximize the sparing attitude to the tooth remains, and not to the manufacturability of the method.
This job requires almost jewelry accuracy, painstaking attitude and, moreover, the result will not be assessed immediately and may even be forgotten (the highest invisible praise to the doctor), and decent pay arises through the years, only with an increased reputation. This approach to patients is less common than the desire to quickly make money on branded expensive implants.
Despite the nasty name stump tab, well executed, gives an excellent result:
- has the most gentle effect;
- leaves the root of a tooth in its native place;
- increases the surface of the support and as a result gives a secure fit and comfort.
For achievement reliable result the circulatory tissues should be well researched, and if an infectious focus is found, they are thoroughly cured. Not every doctor will undertake hard work with an unknown result - it is easier and faster to remove the root than to achieve a difficult restoration.
Reliability of the root and confidence in the absence of inflammatory processes - required condition to continue work that may be delayed.
The canal is completely cleared not less than the height of the future crown and expands to 1.5–2 mm and further to the cone. All undercuts in the cavity of the tooth are removed. For single-root support tab tooth do additional cavity so that the structure does not disintegrate from rotational loads. For multi-root tabs such manipulation is not required.
Making the stump tab
The doctor, who treats with respect to his and others' work, as well as to the patient, carefully selects even the material of the model: the wax used by some masters is a very unreliable material. Ashless injection molded plastic from recognized manufacturers - best option (DuraLay kit).
-
Making an exact model requires skill and spatial imagination when processing channels (otherwise, the frozen model may not be recoverable and then the plastic will have to be drilled so that it can be pulled out). - Kule inlays are molded from various alloys. Each of them may have its drawbacks. Titanium has sufficient hardness and bioinertness, but has some brittleness.
- The bactericidal properties of silver-palladium alloys are good, but they can cause pigmentation of the gums, especially in the case of restoration of the roots that are destroyed below the gum. Chromo-cobalt alloy is difficult to process. The best is gold alloy with 10% platinum. Nowadays, special glass fibers and zirconia ceramics are increasingly used.
Further, a very conscientious master (doctor) makes fitting. The point of such a fit is that there should be no premature contact between the tab and the root - otherwise there will not be a layer of cement in this place. After fitting, the places of premature contact are removed.
Material for production
Ideally made and correctly inserted construction has a continuous thin layer of cement between the insert and the inner surface of the channel. The quality of the composite cement is as crucial as the careful fit of the insert. One of the best is considered glass ionomer fixing cement firms GC (Japan).
The basis for a tooth with parallel channels is exactly the same. But the stump insert for a tooth with three channels is much more difficult to manufacture. For each channel, a separate tab is made, and then the overall collapsible matrix is cast: monolithic with a tab for the main channel and with holes for the tabs of other channels. The service life of such tabs is 5–10 years. It remains only to make the crown and put it on the base.
Even from this superficial description of work, it is clear that it requires painstaking work and not everyone is able to adequately evaluate it, so doctors do not advertise this possibility, which they themselves perceive as ungrateful work. But doctors, initially aimed at a good stable result, gradually deserve respect and an excellent reputation, and in the end receive an extensive clientele.
On the basis, made in this way can be planted and the bridge of several crowns.
Pin tooth
There is a huge variety of both standard pins, and crowns to them and methods of fastening. This method of tooth restoration is more technological, faster to manufacture, cheaper than the stump tab, but at the same time inferior to it in reliability.
Requirements for the integrity of the root are almost the same: it must be of sufficient length, is not susceptible to caries and without inflammatory processes. Pin and mounting method selected in each case individually.
For example, if the root walls are rather thin, and it can break, then a special ring made of gold alloy is fitted to the turned neck of the tooth and the plate is soldered to it, thus obtaining a cap on the root. In this cap, a hole for the pin is drilled in the right place, solder it and, after fitting, fix the porcelain or plastic crown.
Implants
An implant (the word implant is considered correct, and an implant is a person, as well as a contestant, saboteur, etc.), that is, artificial rootLike a crown, which is attached to it, they can differ markedly in price depending on the material, as well as the implantation methods, the clinic and the complexity of the operation.
The most famous implants and their manufacturers:
-
Nobel is a Swiss-American company. - Astra Tech is a Swiss manufacturer.
- ARDS is an Israeli manufacturer and developer.
- Bicon - produces original short implants.
- Alpha Bio - excellent Israeli manufacturers.
- MIS - Israeli company produces a wide range of models.
- Dentium is a South Korean company that has mastered the production of implants Implantium, the latest tools and restoration materials.
Price of implants: from 6,500 to 50,000 rubles, and with accompanying work it may exceed 150,000 rubles.
Implant designs are very numerous, well-known manufacturers guarantee their strength and reliability.This can be trusted - it would be strange if people had not been able to start producing expensive, but reliable self-tapping screws with a collapsible head, and an artificial tooth implant, as a rule, differs little from a conventional screw 70 years after the atomic bomb was created.
Specialists Tips and Recommendations
The point is not the strength and reliability of the metal parts themselves, but how the biological object (jaw) interacts with the alien body. Therefore, the question of which tooth should be inserted should be formulated differently: how to find a good doctor?
It depends on him how the preliminary survey will be conducted and the whole process in many ways difficult. Massive advertising and spectacular photos guarantee a price at best. It is necessary to seek not only a decent clinic, but also great doctor. A good doctor probably has many grateful patients, but not all of them, smiling with a pleasant smile, will want to remember: what bad teeth he once had.
Science and technology have gone far ahead, but biology in the background of cybernetics and nuclear physics looks so far somehow helpless - the main thing is still to come. All that the dentists use is created mostly by technicians, physicists and programmers have introduced the tomograph, and the contribution of biologists has so far been hardly noticeable.
When an elegant, biological solution is found to grow natural teeth, then screwing metal screws (implants) into the living jaw with a shudder will be perceived as medieval barbarism, like a wooden leg instead of sawn wood.
Well, now? Now, if you need to insert a tooth, and even more so an implant - the old advice remains in force: look for a doctor, good doctor. And about advertising implants and zirconium dioxide, if necessary, he himself will remind.
