Nothing can be more attractive than a healthy, beautiful smile. You must have to take care of your teeth and solve any issues related to it to keep that smile glowing. Sometimes, your dentist may advise you to treat a condition using a dental crown. A crown is a ‘cap’ that covers a tooth, to restore its normal shape and size, to strengthen, to ease the pain, or to improve its appearance.

Your tooth is made up of two parts, one is a root and the other is a crown. The part above the gum line is known as a clinical crown. A cap or dental crown is a restoration that covers the outer side of your clinical crown, to restore its shape, size, and strength, and improve its appearance. Dental crowns may be made from, a metal such as gold or another alloy, stainless steel, porcelain fused to metal, all resin, all ceramic, Zirconia or EMAX

All Metals Crowns

As the name implies these crowns are made up of metal. Metal crowns withstand biting and chewing forces well and probably last the longest in terms of wear down.

ADVANTAGES:

  • High Strength
  • More Longevity
  • High Compatibility
  • Cheaper in price

DISADVANTAGE:

  • Since it is made up of metal so it doesn’t look as esthetic as other crowns

Porcelain-fused-to-metal Crowns:

These dental crowns have a metal coping inside and tooth colored ceramic layer outside which can be color matched to your adjacent teeth so that they look most like normal teeth.

THERE ARE TWO VARIANTS IN THESE

  1. Conventional PFM crowns: these are made in the furnace in laboratories
  2. CAD CAM pfm crowns: These are made through cad cam technology so have very precise fit ad good margin adaptation. These crowns also come with a warranty ranging from 10 to 15 yrs.

ADVANTAGES

  • Looks esthetic compared to a metal crown
  • Cheaper than metal free crown yet provide the advantage of color matching to the adjacent tooth

DISADVANTAGE

  • With time when your gums recess, a bluish hue of metal may be visible around your gum line

Zirconia crown

Zirconia crown is getting more and more popularity due to its extreme durability and natural look. It is a superior quality metal free crown.

ADVANTAGES:

  • Superior looks:
  • More confident smile
  • 100% biocompatible
  • Extraordinarily tough
  • They bond well with your tooth
  • Metal-free

DISADVANTAGE

  • Sligh Costly Compare to SLIGHT COSTLY COMPARE TO OTHER OPTIONS.

EMAX Crown

EMAX is measured to be the finest match for natural teeth because of its transparency. It comes in small blocks for a conventional wax & press technique, so you will be able to gain exact fit and improved strength.

ADVANTAGES

  • Best esthetics

DISADVANTAGE

  • Costly

How to choose a crown

While selecting a crown, it’s very important to know that there’s no single type of crown that always makes the best choice in every application. The right selection of crowns constantly differs depending on the requirements of the patient’s exact conditions. Here are some examples that can give you an idea of what types of crowns commonly make the best choice in certain conditions.

For front teeth

If your lip line is very high, your front teeth will mostly be on display to others. In this situation, placing an all-ceramic crown(E max) might be the first option because of the esthetics that this kind of restoration can give. Placing a porcelain-fused-to-metal or milled all-ceramic may also give better results.

When only a portion of the teeth is visible, the esthetic demands is reduced and therefore, other characteristics such as strength and durability may be given more importance in the selection process. Porcelain-fused-to-metal, all-ceramic or milled all-ceramic might be considered for this type of application.

For Back Teeth:

  • Molars:- If patient’s molars show very little while opening their mouth, the strength and durability can be the main criteria of selecting a crown and in conditions where the appearance of molars is an issue, porcelain-fused-to-metal crowns provide excellent service and are more aesthetically satisfying than all-metal ones. Milled all-ceramic crowns (particularly zirconia) may also be a sensible choice.
  • Premolars:- Although premolars usually hold a prominent spot in a person’s smile, they are defined as ‘back teeth’ and it can be expected that they may be exposed to heavy chewing forces. Porcelain-Fused-To-Metal crowns which are attractive in appearance and have a long track record of being strong, durable restorations can be a suitable option.

Do not delay and select the best crown to protect your teeth and enhance your beautiful smile.

Prolonging the Life of Your Dental Crowns


The longevity of the full coverage dental crown is determined by the precision of its fit to the underlying tooth. The fit can vary tremendously and requires attention to detail by the providing dentist. An ill-fitted crown can house bacteria that may build into more serious tooth decay in years to come

Aftercare Precautions


  • Maintain proper oral hygiene habits by brushing twice daily and flossing with dental floss or interdental cleaners (specially designed brushes and sticks) once a day
  • Avoid chewing hard foods, ice or other hard objects, since this could damage your crown. It also is important to avoid biting your fingernails and grinding your teeth, which could significantly shorten its lifespan
  • If you habitually clench or grind your teeth, your dentist may recommend wearing a night-time mouth guard to offer protection while sleeping

Procedure of Crowning


To perform the dental crown procedure, your dentist prepares the tooth and makes a molded impression of the teeth to send to a dental laboratory. A fitted, temporary crown is created during this visit to temporarily protect the tooth while the final restoration is being made in the dental laboratory. Once completed, the crown can be cemented or adhesively bonded at a later visit.

A recent technology that we have, CAD/CAM technology (computer-aided design/manufacturing technology) has evolved to display a 3-D picture of the teeth. A restoration is then created through milling of a ceramic block. If this technology is located in the dental office (chair-side CAD/CAM), there will be no need for a temporary or return visit for the final cementation.

Consultation and Treatment


If tooth decay or damage is so extensive that veneers, direct composite bonding or other conservative treatments aren’t viable treatment options — or if you have undergone root canal therapy — your dentist will consult with you about dental crowns. Whether used to restore a damaged tooth or to create a lifelike tooth replacement for an implant, crowns can be fabricated in dental laboratories or in your dentist’s office, depending on the material.

Part of your consultation may involve taking impressions of your existing tooth (or teeth) as a basis for creating the shape and size of your restoration(s). If crowns will be used as part of a smile makeover, these impressions are used to make models for designing the new length, shape and alignment of your teeth, so that you can preview your new smile before committing to treatment.

Your dentist also will describe the tooth preparation process, as well as your options with regard to local anesthesia (to numb your teeth and surrounding areas) and sedation dentistry, if necessary.

When is a dental crown needed?


There are a variety of situations that require a tooth to be restored with a dental crown. The following are the most common:

  • Root canal: Root canal treatment leaves the tooth hollowed out and predisposes the remaining tooth to cracking. So, a tooth that has had a root canal almost always needs to be restored with a crown immediately to prevent it from fracturing.
  • Cracked tooth syndrome: This is a condition whereby a patient has fractures inside a tooth that cause pain when it is chewed on a certain way. Chewing produces stress on fracture lines that make it feel like it is splitting apart. A crown will hold the tooth together and redistribute the stress evenly throughout the tooth, eliminating the pain in most instances.
  • Broken cusps: Cusps frequently break off of teeth due to trauma or large existing fillings. Since the cusps are the part of the tooth that take the most stress during chewing, they need to be completely covered or the tooth or filling will keep fracturing
  • Excessive wear of teeth: If a person has a habit of grinding their teeth, the teeth will become shorter over time. The teeth can also wear away due to acid erosion due to excessive stomach acidity. Over time, the bite can collapse and the only way of restoring the teeth properly is by increasing the bite and covering the teeth with crowns.
  • Undesirable appearance of teeth: Teeth that have an unacceptable appearance due to color, shape, or spaces between teeth can be made to look very natural and beautiful with crowns
  • Implants and bridges: Crowns are placed on dental implants to restore spaces left from missing teeth. Another way of filling these spaces is with dental bridges, which are made from crowns on the teeth next to the spaces attached to fake teeth in the middle.

What is Crown?


A crown is a type of dental restoration which completely caps or encircles a tooth or dental implant. Crowns are often needed when a large cavity threatens the ongoing health of a tooth. They are typically bonded to the tooth using a dental cement.
