An inlay filling (inlay for short) belongs to the group of so-called rigid filling materials and must be produced in the dental laboratory using an impression.
As an alternative, plastic materials are also used in caries therapy, which are introduced into the tooth in a deformable state and only then hardened. An inlay tooth adjusts to the specific cavity structure of the individual patient adapted workpiece represent.

The production in the dental laboratory is relatively complex and must be carried out with the greatest care so that the inlay can be precisely fitted into the tooth and glued there. Therefore, exact models of the situation in the patient's mouth are necessary. This is obtained through a precision impression.

Basically, such fillings can consist of different materials, often found:
Similar to plastic tooth fillings, inlays are also divided into different classes based on their size. An inlay filling can comprise one to five tooth surfaces, but can only simulate the chewing surfaces of a tooth.
In cases where too one or two Tooth cusps need to be replaced, do not find inlays, but so-called onlays (Dome filling) Application.
In principle, an onlay is just a slightly larger inlay filling (inlay).
To replicate all the cusps of a tooth, an overlay is usually made that can replace the entire chewing surface.
The production of a gold inlay is a great challenge from both a dental and dental technical point of view, because the reproduction of the natural shape of the tooth is not that easy with this material and requires the highest precision.
$config[ads_text2] not foundBefore the inlay can be made, the carious defect must be completely removed from the tooth substance. The tooth is drilled out under local anesthesia. After the tooth decay has been removed, the attending dentist must also remove part of the healthy tooth substance and form a box-shaped cavity (Box preparation).
Then an impression of the tooth is made and plaster of paris is poured in the dental laboratory. The gold inlay can first be formed from wax using the plaster of paris model that is created.
This wax model is then placed in a mold and melted down. This measure creates a cavity within the casting mold, which reflects the exact shape of the tooth cavity and, after being filled with a liquid gold alloy, results in the inlay filling. Then the inlay only needs to be refined and polished.
In the dental practice, the inlay filling can be glued into the tooth with a special cement or plastic.
If, when checking the bite height (occlusion), it turns out that the inlay is too high in some places and thus hinders the natural jaw closure, these places can be ground in a little later.
Inlays made of gold have the advantage that they are special long durability show, but they are very expensive due to the complex production expensive.

An alternative to the inlay fillings just described gold represent the ceramic inlays.
They are made of particularly tough, break-proof ceramic and must also be manufactured in the dental laboratory.
The advantage of this material is the fact that the ceramic can be matched to the natural color of the tooth and thus appears almost invisible.
In addition, tooth walls that are too weak can be stabilized and strengthened by the inlay.
Even when making a ceramic inlay, the carious defect must be completely dried out and the tooth completely dry in advance.
In contrast to tooth preparation in the course of a gold inlay, corners and edges must be avoided with the plastic variant.
The attending dentist can then determine the patient's tooth color using a color scale.
There are basically three different types of ceramic inlays.
Often find:
After production in the dental laboratory, the inlay is inserted into the tooth with a composite adhesive. Since ceramics are very well tolerated in most cases and hardly trigger any allergic reactions, it can be used in almost all patients, but it can contain minor traces of radioactive substances Contain substances. The only risk of triggering allergic reactions is the composite adhesive used.

The supply of a carious tooth with an inlay is not part of the contract medical care. This means that the statutory health insurance companies usually do not cover the costs.
In such cases, the health insurance company only bears the share of the costs that roughly corresponds to the costs of a comparable insurance benefit (for example a normal tooth filling).
A so-called additional cost agreement, which is concluded between the treating dentist and the patient, regulates the necessary additional payment.

For a more noticeable but longer-lasting gold inlay, the patient pays between 450 and 600 euros.
The costs for a ceramic inlay are usually higher, the patient pays several hundred to 1200 euros on average.
The exact costs of the inlay are calculated according to the fee schedule for dentists (GOZ), laboratory and material costs are added.
The co-payment amount to be paid by the patient is exactly the difference between the total price calculated according to the fee schedule for dentists and the payment made by the statutory health insurance.
In addition, patients with additional dental insurance have the option of having this insurance cover the additional costs.
Ceramic as a material for an inlay has a few compared to other materials advantages. It can be adapted exactly to your own tooth color. The result is a very aesthetic restoration of the tooth that also looks natural. Ceramic is also very well tolerated. Allergic reactions are excluded. The stability that is guaranteed by a ceramic inlay is very similar to that of a natural tooth. Thus is a ceramic supply more durable than normal fillings.
disadvantage of the ceramic are the air bubbles or small voids that are often present, which can arise due to minimal processing deviations. In contrast to gold inlays, ceramic inlays can break faster.
Compared to ceramic, however, a gold inlay is suitable for large posterior tooth surfaces. However, allergic reactions can occur. Gold alone would be too soft for an inlay. Hence mixtures, so called Alloys which can also contain other metals such as platinum, nickel, silver or titanium. Compared to plastic fillings, more tooth structure has to be removed with the inlay. It is more expensive than other inlays and, unlike ceramic, it is more likely to transfer heat and cold to the tooth. To avoid this, a so-called underfill is placed between the tooth and the inlay. She shields, among other things thermal stimuli.
The shelf life of an inlay is very long compared to normal fillings. The National Association of Statutory Health Insurance Dentists (KZBV) states that ceramic inlays have a shelf life of at least 10 years. With gold inlays it is 10-15 years. However, these are only Averages.
The restorations often last a little longer. The durability of an inlay depends not only on the fit and fit of the inlay, but also on your own oral hygiene. The better you care for your teeth, the longer the inlay will last. In general, statistics show that around 20% of the inlays need to be replaced after around 15 years.
$config[ads_text1] not foundThe reasons for this are mostly insufficient fastening, Caries below the inlay, Fractions or Cracks in the inlay.
If an inlay has fallen out, a dentist should be consulted immediately. The tooth is now exposed and is particularly sensitive to stimuli.
Once the inlay has been found, it can be brought to the dentist's appointment. However, it can can only be used again in a few cases. Mostly there is caries, which is the reason for the inlay falling out. Due to the caries, the adhesive strength of the inlay on the tooth is lost and the inlay falls out as a result.
It is also possible that a side panel has broken off. This can usually also be felt with the tongue. If the caries is located under the inlay, it must be eliminated and, in most cases, a new inlay must be created. If the tooth decay has already penetrated to the tooth nerve, the tooth needs root canal treatment. When the tooth is very sensitive to heat, cold, acidity and spiciness then this can be a sign of tooth decay.

If an inlay falls out and is accidentally swallowed, there is no need to worry. The inlay will leave the body naturally after 2-3 days. The inlay can also be reinserted when it is found again. It could be disinfected.
Whether or not you make this decision is entirely up to you. In many cases it is important to know that one is here Inlay doesn't fall out for no reason. Most of the time there is caries under the inlay. As a result, this no longer had any adhesive strength and fell out. In any case, a dentist should be visited as soon as possible to have the tooth restored. If you want to be absolutely sure that the inlay has left the body, you can radiographically can be verified, provided the inlay is made of metal.
If an inlay has broken off or a piece has broken out, you can usually feel it with your tongue. In any case, a dentist must be visited to have the defect repaired. The longer you wait, the more food residues and bacteria can accumulate on the edge and subsequently lead to tooth decay.
If a piece breaks out of an inlay, then there is usually an incorrect load on the chewing forces. This can go through Nocturnal stress-related teeth grinding arise or through a incorrect dimensioning of the inlay itself. If this is too high, for example, and force is only exerted on one point of the inlay when biting, it can break.
Pain in the inlay that occurs after years of wearing it is usually caused by caries below the inlay. Often times they go as pulling described Pain With Sensitivity to cold, warmth, heat or sharpness hand in hand.

In most cases, the dentist will first take an X-ray. Caries, for example, can be detected on this. To fix the defect, the inlay must be removed. If the tooth decay has progressed very far, the bacteria may already have infected the dental nerve, which entails a root canal treatment.
If the pain occurs immediately after or a few days after inserting the inlay, a dentist must be consulted immediately. The treatment may have irritated or injured the gums. Furthermore, the tooth is usually sensitive to stimuli due to pressure sensitivity after the new inlay has been inserted.
It can also be that the inlay is incorrectly positioned or that it is too high and consequently also damages the teeth in the opposite jaw.
If an inlay is to be created for a tooth, the tooth in question is first cleared of caries. The tooth is then prepared using grinding instruments according to specified criteria. An impression of the jaw and the opposite jaw is then taken. These are sent to a dental technician.
A temporary plastic is then made, which until the next appointment will be carried. The dental technician uses these negative molds to create two positive molds of the patient's jaw out of plaster of paris. He can then create the inlay.
After production, the inlay is sent back to the dentist and tried on in the patient's mouth. In the case of ceramic as the material of the inlay, the patient must not bite if the inlay has been loosely inserted, otherwise there is a risk of the inlay breaking. The dentist checks the fit of the inlay in the mouth. The contacts to the neighboring teeth are checked using dental floss and the gap-free transitions between the inlay and the tooth are checked using a probe.
If the inlay fits well, it can then be glued in with a cement. Now the patient can bite and any imperfections can be compensated in the case of ceramic in the patient's mouth. If the inlay fits in the patient's mouth when trying it on, then two dates in total Booked at the dentist for the creation of an inlay.
