Lifetime of dental materials in the oral cavity

THE AVERAGE lifespan for seals, crowns, plaques is quite similar and is around 10 years. If your teeth are restored with option 2, then for a shorter time. So, about 10! This, in turn, means that for someone these formations will serve 30 years, but for someone only 5 years, on average between 10 and 15.

In my mind, “I hear” readers oppose the named statistically average numbers available in world literature. Because many people believe that while the seal, crown or bridge is “standing,” IT’S OKAY.

The gap between teeth tissue and restoration determines everything …

Yes, it’s only OK as long as these physician formations are well attached to dental tissue. A tiny (measurable micronos) microgap between materials and teeth tissue is always, unfortunately. (In the case of low-quality work, of course, higher).

So much has been achieved for now with today’s technology and materials. There is still no such “eternal” material created as a whole, undamaged, nature-given TOOTH of its OWN.

With the first day after the tooth is restored, the bacteria actually begin entering the microslot and the remaining tissue in the tooth begins to deteriorate slowly. Just as the ability to mineralize saliva varies, the bacteria (both quantitatively and qualitatively) differ from person to person. The less saliva mineralization capacity, the more virulent the bacteria, the faster the damage occurs. The coincidence of many circumstances then also creates an “average lifetime” for restorations.

If the tooth is “lifeless” (depolated), the patient may not have complaints until the complete collapse of the tooth under Crown, Bridge. Especially when the patient only goes to the dentist for complaints.

If a patient visits a dentist once a year, then controlling their teeth clinically and radiologically, each defect is noticed and repaired in time. This includes crowns, bridges, plaques, seals and is equally important in all cases. In particular, when the patient’s own tooth roots, which nevertheless act as biologically natural “implants” should be maintained for as long as possible … Once the root of the tooth is damaged at bone level, it is no longer possible to use it for further prosthetics without the use of costly, time-consuming interventions, but most often the root should be extracted (extracted).

What else affects the lifespan of my crowns, bridges, seals in the mouth?

The main factors that extend the life expectancy of any modern material or crown in the mouth are:

1. Very good oral hygiene and regular dental control (preventive approach!)
2. Quality work of a doctor (including a technician), including methodically scrupulously fulfilled requirements for cementing and binding materials to dental tissue.
3. Quality materials.

It is also important to:

1. Patient habits and bite peculiarities (e.g. night cutting of teeth, very tight gritting, use of acid products, acid reflux), etc.
2. Some health problems that cause a lack of saliva or the presence of acid in the mouth (e.g. diabetes, acid reflux – reflux, radiation, anorexia, etc.)

How many times will my crowns, bridges, seals, plaques be changed?

It’s easy to work out how many times each of us with some kind of repaired tooth will have to change the restoration or reprose the tooth or change the bridge during our lifetime. Count only 10 years ahead …

Not really, though, as these are today’s achievements. But dental materials, techniques and technology are evolving so quickly that it is likely that “supermaterials” will be created very soon, which will live in a clean and cleaned mouth for much longer!

You’re young. The mere fact that you are interested in the distant fate of your teeth suggests that you are taking care of the health of your teeth. So your tooth roots will welcome the next beautiful China crowns unspoilt.

What are the options for using the root at all?

The root of a cured, filled tooth is the best fixation for the crown of porcelain etc. if once the crown of the tooth itself has disappeared (as in your case). But not every root fits for further use.

1. If the root is damaged and the damage cannot be repaired, the root should be extracted (extracted).
2. If the part of the root in the bone is too short or otherwise anatomically invalid to withstand a mechanical load, the root must be removed (in the case of a removable prosthetic, another solution).
3. If the remaining root length is sufficient, it shall be extended with a seal and a crown shall be placed.
4. If the remaining part of the root is short but usable (meant to be a length in the oral cavity and above bone level), then a connecting element, the root inlet, shall be inserted into the root.

What is Root inlay?

The root inlay is a connecting element that is entrenched into the root of the tooth that connects the root and the renewable tooth crown, serving as the basis for it.

It can be composed of:

• a physician from a blanket (metal or glass fibres, etc.);
• in the laboratory (by pouring the exact copy of the root canal impression) of metal.

Who is “the Crown”?

“Crown” means an artificial coating (“cap”) on the remaining teeth tissue or on the root inlay, which reproduces the size, shape and function of the natural tooth, strengthens and protects the remaining teeth tissue.

They can be made up of:

• metal alloys,
• plastics or
• composite materials,
• ceramics.

Ceramic crowns of metal

They have a metal base/frame underneath the porcelain. The most common metal frames under porcelain are:

• chromium cobalt alloy – durable material in grey metal colour. This colour should be masked to avoid shining through the porcelain. As a result, it’s hard for porcelain to get the transparency of a really natural tooth.
• gold alloy – softer material, which is relatively “the most living”, in the colour closest to the tone of the tooth. It is therefore easier to obtain the characteristic colour of a natural tooth with porcelain.

“Clean” China crowns

They, like metal ceramics, form a foundation (frame) under porcelain. This time it is made of more durable ceramic material (e.g. alumina or zirconium ceramics).

Most popular recently are the crowns of yttrium-stabilised zirconium, which are both durable and aesthetic.

These crowns resemble natural teeth in appearance and transparency. Especially when placed on living teeth, seal-restored foundations or translucent material root inlays.

If there are metal root inlays underneath these crowns, there are difficulties with camouflaging the grey shade that shines through the porcelain. This problem is solved by laying a very thin cartini of gold inside the crown.

Crown-making methods vary, too. They vary in terms of materials and technologies to be used, laboratory capabilities and costs.

Choice

The choice of which crown to cook is determined by the projected load on the tooth and other technical parameters as well as aesthetic requirements and economic opportunities.

Under optimum conditions, you can make crowns with both cermets and pure ceramics that look just like the most beautiful natural teeth.

Implant – when you no longer have your own root

What if roots can no longer be used or they are long gone, the next step is IMPLANTS. The procedure for putting them in appears to have become as routine as other well-known dental procedures.

Normally, after pulling out the tooth, you should wait about 3 months before you can lay an implant. Another 3 months must wait before the implant can be exposed and the “head” of the implant on which the next crown is built is visible. Crown cooking is done in a similar way to that on the tooth with cermets or pure ceramic crowns. So overall, it takes about 6 months for a patient to walk with temporary prostheses.

There are situations where an implant and temporary crown are placed on it immediately on the same day after the tooth was pulled out. Thus, the patient does not need to be toothless for any day. Then the real Crows are made in 3 months.

Types of implants

There are different manufacturers whose implant designs differ slightly, but they are basically all screw-type implants with success of 90% for 10 years. Swedish, German and US producers are popular in Latvia. In fact, doctors expect the bone screw to last a patient’s entire life. It might be necessary to change only the prosthesis on top.

Your doctor will decide with the patient which implant system will be used. This is determined by the quality and quantity of the patient’s bone, as well as the planned type of prosthesis.

Prices vary according to producer prices, medical and laboratory costs.
