Zubne krunice štite oštećen, napukao ili slomljen zub. One jačaju postojeći, oštećen zub i omogućavaju mu da očuva svoju funkcionalnost.

 

U kojim slučajevima je potrebna krunica?

• Ako je zub suviše oštećen karijesom i nema dovoljno zubne strukture koja bi podržala plombu i održala funkcionalnost.

• Ako je veliki deo zuba polomljen i kompozitna nadogradnja se ne može uraditi

• Ako imate veliku šupljinu na zubu i umesto velike plombe radije biste stavili krunicu.

• Ako imate implantat umesto zuba, krunica će biti postavljena na njega.

• Nakon lečenje kanala korena, krunica je često potrebna za jačanje zuba.

• Ukoliko ste oštetili zube do tačke na kojoj su krunice jedina opcija.

• Iz estetskih razloga, za poboljšanje izgleda osmeha, možete se odlučiti za porcelanske kozmetičke krunice.

 

Da li su krunice uvek najbolja opcija?

Krunice ne bi trebale biti prvi izbor za poboljšanje estetike zuba, jer stomatolog mora izbrusiti veliki deo prirodnog zuba. Prvi izbor su svakako manje invazivne procedure koje uključuju zubne navlake ili kompozitnu nadogradnju.

Krunice su potrebne onda kada je funkcionalnost zuba ugrožena, jer navlake i kompozitna nadogradnja ili plomba mogu biti opcija samo kada postoji dovoljno potporne strukture prirodnog zuba.

Od kojih materijala mogu biti izrađene krunice?

U savremenoj stomatologiji postoji širok izbor dentalnih materijala koje možete izabrati. Neke krunice su napravljene od čistog zlata, druge su od legure metala na koje se postavlja porcelanska (keramička) navlaka. Nakon nekog vremena, metalo-keramičke krunice mogu početi prikazivati tamne linije desni koje nisu estetski privlačne. Potpuno porcelanske, odnosno keramičke krunice su najbolji izbor za prirodni izgled zuba.

Kako izgleda postupak postavljanja zubne krunice?

Nakon što ste se konsultovali sa svojim stomatologom i razmotrili sve mogućnosti lečenja, on/ona će pripremiti zub za postavljanje krunice.

Prva faza je čišćenje zuba, uklanjanje karijesa i brušenje pomoću posebne stomatološke bušilice za oblikovanje zuba u lokalnoj anesteziji. Oblik pripremljenog zuba je obično zašiljen kako bi se krunica mogla postaviti na vrhu.

Nakon što se pripremi zub, uzima se otisak. Otisak se šalje u zubotehničku laboratoriju, gde će se pomoću njega napraviti krunica koja će se savršeno uklopiti. To obično ne traje duže od dve do tri nedelje. Tokom tog vremena, stomatolog će vam pomoću privremene krunice zaštititi pripremljeni zub (Ukoliko se krunice izrađuju u kratkom roku, odnosno za 2-3 dana, privremene krunice se ne postavljaju).

U sledećoj poseti, Vaš stomatolog će ukloniti privremenu krunicu i spoljašnju površinu zuba će tretirati posebnom kiselinom kako bi zubnom cementu napravio dobru površinu za prijanjanje. On će postaviti krunu na zub da vidi da li se uklapa u osmeh i  da li ima pravu nijansu i oblik. Nakon što ste i Vi i stomatolog zadovoljni izgledom krunice, stomatolog će pomoću cementa krunu učvrstiti na svom mestu.

 

Koji je vek trajanja krunica?

To će uveliko zavisiti od toga kako brinete o Vašim zubima. Krunice zahtevaju isti stepen brige kao i prirodni zubi. Pod uslovom da imate dobru oralnu higijenu, redovno posećujete svog stomatologa, pravilno se hranite i ne radite stvari kao što su otvaranje pivske flaše zubima, kvalitetne krunice mogu trajati 10-15 godina.

 Dental crowns are restorations that protect damaged, cracked or broken down teeth. A crown strengthens your existing, damaged tooth so as to preserve its functionality.

 

Why might I need crowns?

  • If your tooth has undergone significant decay and there is not enough tooth structure remaining to support a filling or an inlay and maintain functionaility.
  • If a large portion of your tooth has fractured and it cannot be built up using traditional composite bonding techniques .
  • If you have a large cavity and opt for the additional protection a crown offers to your tooth over a large composite filling or an inlay.
  • If you have had a dental implant to replace a missing tooth, a crown will be fitted to the abutment of the titanium implant.
  • Following root canal treatment, a crown is often needed to strengthen the tooth.
  • If you grind your teeth and have a poor diet, acid errosion may reduce your teeth to a point where the only option available is to crown them.
  • For cosmetic reasons, to improve the aesthetics of your smile, you may opt for all porcelain cosmetic crowns.


 

Are dental crowns always the best option?

Crowns should not be the first choice just to improve the aesthetics of your teeth, because a dentist needs to grind a significant portion of the original tooth away. Less invasive alternatives include veneers or dental bonding. Crowns are required when the strength of the tooth supporting the restoration is compromised, since veneers and dental bonding restorations are only as strong as the supporting tooth.

What materials can crowns be made from?

In modern-day dentistry there is a wide variety of dental materials to choose from. Some crowns are made from full gold, where as others are made from an alloy of metals fused to a porcelain outer shell. After time, crowns that are made from a combination of metal fused to porcelain can begin to show dark gum lines that are not aesthetically attractive. All-porcelain or ceramic crowns are the best choice for a natural cosmetic look.


What does the procedure of having dental crowns fitted involve?

Once you have had a consultation with your dentist and discussed all the treatment options, he/she will prepare the tooth for crowning.

The first stage is to clean the tooth, remove any decay and reshape it using a burr (a special dental drill for shaping teeth) under local anaesthesia. The shape of the prepared tooth is usually tapered to allow the crown sit comfortably over the top of it.


Once the tooth is prepared, an impression (mould) of your teeth will be taken using a special “dental putty”. This impression is sent to a dental laboratory, which will use the impression of the prepared tooth as a guide to fabricate the new crown to fit perfectly. It usually takes between two to three weeks for a laboratory technician to custom-fabricate your new crown. During this time, your dentist will fit you with a temporary crown to cover and protect your prepared tooth (If the crowns are made in the short term, ie for 2-3 days, the temporary crowns are not put).

On your second visit, your dentist will remove the temporary crown and roughen the outer surface of your prepared tooth with a special etching acid to give the dental cement a good surface to bond to. Your dentist will sit the crown over your tooth to see if it fits with your smile correctly and is the right colour and shape. Once you are both happy with the restoration and how it looks, your dentist will cement the crown firmly into place.

 

How long do crowns last?

This will depend largely on how well you look after your teeth. Dental crowns require the same level of care and attention as your natural teeth. Provided you have a good oral hygiene program, attend regular checkups at your dentist, don’t grind your teeth, maintain a tooth-kind diet and don’t do things like open beer bottles with your teeth, a high-quality dental crown can last 10-15 years.
