The Main Types of Dental Crowns

Mar 01, 2020

A dental crown basically refers to a ‘cap’ that is placed on defective teeth to correct a flaw. The Tooth Family Dental offers a wide range of various types of crowns. The cap can be used to repair the front teeth or back teeth, that rarely show. When used to fix front teeth, materials with high aesthetic value such as porcelain are best preferred.

When choosing the type of crown, it’s important to consider the following factors.

  • Cost – Choose a crown that you’re able to pay for. If you have a working insurance cover, your options are more diversified.
  • Strength – Note that crowns fill the enamel. So, you’ll want to choose a crown strong enough that won’t easily break with pressure from chewing.
  • Durability – Having considered strength, durability is another vital point to deliberate. You don’t want a crown that will need replacement after a few seasons of use.

Different patients have various reasons why they need crowning — some for cosmetic purposes and others strictly medical. You can let the dentist suggest the best suitable option for you with respect to your needs.

Same-Day Crown

This term describes a crown that is installed in a single appointment. You don’t have to wait for the processing of your crown for weeks. Same-day crowns are made mainly from ceramic blocks and are done right in the office.

Dentists who offer one-day crown use Computer-Aided Design (CAD) or Computer-Aided Manufacturing (CAM) technology for the procedure.

Temporary Crowns

As the name suggests, these crowns are crafted to last for only a short duration of time. These crowns are placed with an easy to remove adhesive, so they aren’t as strong compared to permanent crowns. Mostly, a temporary crown procedure is done while you wait for the completion of your permanent crown.

¾ Crowns

¾ crowns, also referred to as inlays, are meant to cover some part of your tooth. They are recommended if you don’t qualify for a full crown.

Permanent Crowns

These are the most applied forms of crowns in patients. Dental professionals use these crowns to fix anomalies such as:

  • Covering discolored teeth
  • Holding together a dental bridge
  • Restoring a severely worn out or broken teeth
  • Covering dental implants
  • Safeguarding frail teeth from decay effects or fracturing
  • Cementing together cracked parts of a tooth

Types of dental crowns

  • Metals – Metallic crowns are best to withstand chewing and biting force. They are made from alloys rich in gold and platinum. Cobalt-chromium and nickel-chromium metal alloys are also used in metal crowns. Basically, metal crowns have the least rate of wear down and are most durable as they rarely break or chip from pressure.
  • Resin – These are the least expensive crowns. However, they are more susceptible to breakage and fractures than porcelain and metal types.
  • Stainless Steel – These are used as temporary remedies, mainly for children. They help protect milk teeth from damage and further decay. They are used as the permanent crown is crafted from a different material. With stainless steel crowns, the child doesn’t need regular visits for maintenance.
  • Porcelain Metal Fused – They offer more strength to teeth and are ideal for bonding long bridges. Unlike metal crowns, these crowns can be adjusted to match your natural teeth color. The porcelain part of the crown can chip off, so they aren’t as durable as metallic types.
  • Ceramic – Ceramics have a more natural look than other crown types. They are suitable both for back and front teeth.

Procedure

One-day procedure

  • Digital pictures of your mouth are taken
  • The dentist uses a digital scan from the photos to create your crown in the office immediately.
  • After the scan, the crown will be ready in 2 – 4 hours. It is then glued into place upon completion.

Multiple visit procedure

  • An examination which might involve taking a mold and X-ray pictures of the affected teeth is made.
  • The enamel is then removed with a grinding tool.
  • An impression of the prepared tooth is then made.
  • Temporary crowns are used on the prepared teeth to safeguard them
  • The impression taken is then sent to the lab. The crown might be made over several weeks.
  • You return for a second visit where the crown is cemented into place.
