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.

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.
Basic functions of crowns
It would be wrong to consider restoration of aesthetics to be the main function of using such an orthopedic design. A crown really fills a gap in the dentition, but there are several additional tasks:
- Preservation of the socket in the gum. This is necessary in order to reduce the complexity and trauma of surgical intervention during the process.
- Keeping teeth in place. When a person is missing one of the teeth, there is a possibility that the neighboring teeth will begin to shift and more gaps and crevices will appear in the row. When a temporary crown is placed, this phenomenon is not observed.
- Elimination of pain. This is especially true if the prosthetic procedure does not require removal of the nerve. In this case, while the permanent crown is being created, the temporary one will eliminate the likelihood of strong pressure and discomfort.
Since the prosthetic technology itself involves slight grinding of the enamel of adjacent teeth, it is important to provide them with additional protection. And temporary crowns do an excellent job with this task. The development of hypersensitivity, as well as the risk of caries, is excluded.
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.
Why do you need a “temporary” solution?
Life experience suggests that when we are offered incomprehensible solutions or there are doubts about their appropriateness, the fragile, not yet fully formed trust in a specialist, and in our case in a doctor, can be destroyed.
The fact that, in principle, without teeth is bad is clear, therefore it is advisable to restore them and, if possible, not to postpone prosthetics for a long time.
However, why make “temporary” crowns or even more complex “temporary” orthopedic structures, because they cost money, and wearing them delays the completion of treatment?
Maybe it would be better to immediately manufacture and install the desired denture?
Now we will try to explain the importance of the temporary prosthetics stage and tell you how it affects the course of treatment and the final result.
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.
Why are such prostheses needed - functions and purpose?
What are temporary crowns needed for, and why are they placed? The manufacture of any permanent dentures requires a certain amount of time – usually three or more days. At the same time, the supporting teeth have already passed the processing stage and do not look quite aesthetically pleasing - after all, they are quite sharply ground. Therefore, if the question arises - why are temporary crowns placed before permanent ones, you need to understand that they serve the following purposes:
- protection of the ground tooth and surrounding gums from mechanical damage: during chewing food or brushing with a toothbrush. Inflammation of the gums or dental “nerve” should not be allowed. It is also necessary to maintain the shape of the support, because the permanent “cap” is made using casts from the support – and if it breaks, you will have to start prosthetics “from scratch”
- protection from external irritants: acids, temperature changes,
- restoration of dental aesthetics,
- restoration of the functionality of the tooth: of course, in this case its “functionality” will be incomplete, because strong chewing pressure can damage the root or implant,
- acceleration of adaptation to a permanent prosthesis,
- normalization and correction of the position of the gums, if such a crown is placed on a newly installed implant.

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.
Question No. 7: what are the consequences of untimely crown replacement?
The outer layer of the temporary structure is short-lived. Over time it wears off. If the provisional restoration is not replaced within the time frame recommended by doctors, the material may become damaged and uneven edges will appear on it, which injure the mucous membrane and antagonist teeth located on the opposite jaw. If the plastic loses its integrity and homogeneity, then bacteria and pieces of food will clog into the smallest cracks of the prosthesis, provoking an inflammatory process in the oral cavity.
In addition, with prolonged use, artificial dentures will begin to wear down, which will negatively affect the bite and normal functionality of the maxillofacial apparatus. Because of this, problems with chewing food, headaches, and gastrointestinal diseases may begin.
Stages of installing temporary crowns
- Tooth preparation
– the doctor gives the stump the desired shape (depulps, fills canals, strengthens with a stump inlay, grinds) - Taking impressions
– using an impression tray and plastic material, an impression is taken from the patient’s jaw - Making a crown
- the prosthesis is made directly (in the dentist's chair) or indirectly (in the laboratory) - Installation
- fixation of the temporary crown is performed with dental cement.

Question No. 8: how to care for temporary restorations?
Care must be carried out carefully, but very carefully. To begin with, you should buy a brush with soft bristles and a toothpaste without abrasive particles (it should not be bleaching!). If you use “harsh” hygiene products, there is a risk of prematurely damaging the artificial material and ruining its appearance.
For complete oral care, it is recommended to purchase an irrigator, because you have a temporary prosthesis installed. At the junction with the gum, plaque must be removed more carefully, since this is where it accumulates the most. The irrigator also helps to care for the gums, the health of which is very important for the safety of the teeth and the restorations themselves. With the help of a directed jet, the mucous membranes can be gently massaged, increasing their blood flow.
Using an irrigator will help with oral hygiene
If an irrigator and a brush with soft bristles are ideal assistants in the fight against contamination of artificial material, then you should be very careful when using floss. Some doctors advise avoiding flossing altogether, as the teeth and gums under the structures become less sensitive, and if the cleaning technique is incorrect, there is a risk of injuring the mucous membrane. In addition, careless use of thread can cause breakage or peeling of the prosthesis.
If you still use floss, remember that after use it is better to carefully pull it out of the interdental space by only one end.
If you have provisional restorations, it is better to stop smoking and consuming products with dyes, as they change the shade of artificial materials. Also, you should not lean on hard and sticky food, because this can destroy your artificial teeth ahead of time, or lead to their deformation.
Question No. 9: what to do if the crown falls out?
Considering that the provisional prosthesis is fixed with temporary, that is, non-permanent cement, this situation is possible. If this happens, then nothing can or should be done at home. It is necessary to consult a doctor as soon as possible, who will clean the structure and fix it again.
If a crown falls out, you should consult a specialist.
Remember, in some cases the crown falls out not due to depressurization of the cement or the use of low-quality glue, but due to chipping and destruction of hard tissues and the development of an inflammatory process.
Not only the crown, but also the filling can fall out! What to do in such a situation? Read the article on the website: “A filling fell out - answers to the most popular questions about the problem.”
