Provisional or temporary crowns are installed while preparing for permanent prosthetics. They protect sharpened teeth from the aggressive environment of the oral cavity, restore chewing function, the aesthetics of a smile, provide comfort during communication, and prevent gum growth until a permanent orthopedic structure is installed. The prosthesis is made from high-quality, non-toxic materials. Despite the fact that these are temporary orthopedic structures, their functional significance is very high. The cost of a temporary crown per tooth depends on the material, type of product, and manufacturing method.

• When to use:
  Severely damaged tooth (temporarily)
• Treatment period:
  1 visit
• Type of anesthesia:
  Local
• Healing period:
  no
• Procedure time:
  5-15 minutes
• Age restrictions:
  From 18 years old

Why are provisional crowns needed?

• Prevention of changes in bite – eliminates the displacement of teeth in a row;
• protection from infections, thermal, chemical irritants to the tissue of prepared units;
• preventing gum growth around the stump;
• maintaining normal diction and correct pronunciation;
• restoration of chewing function;
• formation of an aesthetic gingival margin;
• prevention of mechanical damage to teeth and gums;
• adaptation to the volume and shape of the future permanent orthopedic system.

A temporary dental crown is installed on your own tooth, as well as on an implant, immediately after its implantation into the bone tissue using a one-stage protocol or 10-14 days before installing a permanent orthopedic structure using classical technology.

Materials

Various plastics (acrylic, polymethyl methacrylate PMMA) and composites are used for manufacturing. The materials reproduce different colors and shades, are quite durable, and can withstand moderate chewing load. For complex rehabilitation of multiple dental defects, metal-composite or metal-plastic structures on implants are used. Such prostheses consist of a lightweight metal frame lined with composite or plastic. The crown is secured with cement. It holds it firmly, but at the same time, the prosthesis can be easily removed for treatment and installed again.

I got a temporary lab crown two months ago. It's time to do a re-prosthesis, but it hasn't broken and I'm satisfied with its appearance. How much longer can I walk with a prosthesis?

This question will be better answered by an orthopedist after examining the situation. The prosthesis has a service life that should not be exceeded.

I got a temporary crown three months ago. Yesterday a corner broke off from it. How urgently do I need to come to the clinic for re-prosthetics?

A three-month period is the standard period for wearing a temporary prosthesis, which should not be much exceeded. If the corner of the crown is broken, the sharp edge can injure the mucous membrane and cause inflammation. If possible, you should come to our clinic as quickly as possible; if this is not possible, you should contact orthopedists at your place of residence so that they can polish the chip.

What are they made from?

For the manufacture of dental temporary crowns, materials with low strength are used, which can be removed or removed from the surface of the tooth without injury. In addition, the use of expensive materials is not advisable, because the service life is on average 2-3 weeks.

Temporary crowns are made from materials:

• acrylic composition;
• plastic;
• composites.

The material used for the manufacture of dental orthopedic products must meet the following requirements:

• the hardening process occurs quickly, but the specialist has enough time for application and correction;
• melting is performed exclusively at low temperatures while maintaining the strength of the product.

The temporary crown must be safe for the patient and perform its functions taking into account the anatomical features of the jaw. If the design causes significant discomfort or causes an allergic reaction, it must be replaced.

Manufacturing methods

Provisional structures are made by direct and indirect methods.

• Direct
  is an express technique that allows you to make a crown from plastic or composite in a matter of minutes
  in the dentist’s chair
  . The doctor takes an impression of the patient’s jaw using silicone paste, prepares the stump (grinds the tooth, giving it the desired shape). Fills a silicone impression with plastic material and places it on the tooth. After the material has hardened, an impression is taken, the prosthesis is given the desired shape according to the bite, firmly fixed with dental cement, ground, and polished.
• Indirect
  – a temporary plastic crown for a tooth is made in a dental laboratory, based on an impression of the patient’s jaw. The technique allows you to take into account the characteristics of jaw closure and the structure of the dentition. jaw movements. The prosthesis can be made in the laboratory in two ways - by a dental technician using the classical method or using CAD/CAM technology.

The direct method is economical, fast, but does not provide good aesthetics. Making a crown using the indirect method takes 1-2 days. The dentures fit exactly and are identical to natural teeth in shape and shade. Provisional structures made of thermoplastic material PMMA are reliable, durable, and suitable for patients with allergies to plastics.

How long does the service life last?

How long can you wear temporary crowns? Most patients go with them for a fairly short period of time - about 2 weeks. If more time is required to manufacture the prosthesis, the service life can be increased to 1 month. Dentists do not recommend wearing plastic “caps” for longer, because... they quickly become unusable, and as a result, the supporting tooth “suffers.” But composite ones can be worn for a longer period - up to several months, but not more than 1 year. Temporary dentures on implants are usually worn until the implant itself has taken root - up to 6 months. Here they have a slightly different fixation system, which is why the wearing period increases.

“I wanted to whiten my teeth before my wedding, but I went too far with the exposure time of the whitening strips and ended up with serious problems. The dentist said that I need to get crowns because with my fillings it is useless to build them up. And “Day X” is getting closer... I had to install temporary composite ones for now, they said that I could do this for 3-4 months. And the doctor chose the color very well, the smile in the photos is simply gorgeous!”

Temporary prosthetics of anterior teeth

Prosthetics with a temporary crown of incisors or fangs involves preserving the aesthetics of the smile. Prostheses are made in a laboratory (indirect) method. Select a shade of material similar to the color of the natural enamel of neighboring units. Installing a temporary crown on the front tooth allows you to make the intermediate stage of prosthetics more comfortable.

Plastic imitates enamel well and can withstand moderate chewing load. The procedure for installing provisional structures on the anterior or chewing units is no different. The only difference is that plastic structures on molars and premolars wear out and crack very quickly. If you plan to wear a provisional system for longer than 3-4 weeks, it is recommended to order lightweight metal-plastic or metal-composite prostheses.

When installing crowns or bridges, it becomes necessary to treat the tooth surface.
In this case, the orthopedic dentist must remove a thin layer of tissue to the thickness of the wall of the future structure (0.3-0.7 mm on average). So that while waiting for the finished dentures to be made, the patient can smile, speak clearly and eat comfortably, the created stumps must be covered with protective caps. They will allow you not to damage the supports of the structure and not to injure the mucous membranes. For this purpose a temporary crown made of composite, acrylic or plastic is used. Its materials do not have high strength and are not highly refractive or shiny, because the cap is usually only needed for a couple of weeks and does not catch the eye in the same way as treated stumps would.

The second situation when it is necessary to resort to this solution is the period of implant healing with a two-stage implantation technique. In this case, the permanent prosthesis is not installed immediately, but after stabilization of the artificial root (after 2-4 months).

Stages of installing temporary crowns

1. Tooth preparation
   – the doctor gives the stump the desired shape (depulps, fills canals, strengthens with a stump inlay, grinds)
2. Taking impressions
   – using an impression tray and plastic material, an impression is taken from the patient’s jaw
3. Making a crown
   - the prosthesis is made directly (in the dentist's chair) or indirectly (in the laboratory)
4. Installation
   - fixation of the temporary crown is performed with dental cement.

Comments

I have a very decayed tooth in my mouth. There has been a huge filling on it for several years now. The last time I visited the clinic, the doctor recommended replacing the filling with a crown, at least temporarily. I don’t know whether to leave everything as it is or change it?

Dmitry (09.27.2020 at 20:03) Reply to comment

If a little more than half of the tooth remains, then wearing a large filling is not advisable, because it can very unexpectedly collapse and chip along with the walls of the tooth. Or it can crack, and then the tooth can literally fall apart piece by piece. If this happens, then you will have to restore the tooth at great expense, for example, installing not only a crown, but also strengthening the root with a pin or stump insert. You need to decide on prosthetics faster. Alternatively, while you are choosing the material for a permanent crown, you can install a temporary one.

Purpose

A tooth ground down for a crown becomes unattractive. What remains of it is a “stump”. What if it's a front incisor? The person will experience a feeling of embarrassment, discomfort, and will begin to constantly cover his mouth with his hand. Temporary (provisional) crowns solve this problem by visually restoring integrity during the period of production of the permanent one.

In addition to the aesthetic function, they solve problems such as:

• dulls the sensitivity of dental tissue to cold, hot and other irritants;
• prevent gum swelling;
• securely fix the tooth, preventing its displacement and loosening;
• maintain diction;
• temporarily restore tooth function.

The products are designed for a short period of operation, therefore they are made of porous material. For this reason, a temporary structure cannot be used as a permanent one. If you do not follow the rules of oral hygiene, over time, pathogenic microflora will penetrate through the pores of the provisional product to the ground tooth and cause its inflammation.

When drinking wine, coffee, tea, as well as smoking, the plastic can change its color, so before installing a standard one, it is better to avoid using coloring products.

Sometimes temporary structures are installed due to lack of money for a regular crown. This is allowed, but you still need to remember that the temporary product is designed for a short period of use, so there is no need to postpone your next visit to the doctor for too long. The permanent one will serve for many years and reliably protect the tooth underneath from negative influences.
