Types of Artificial Teeth and Dental Crowns
There is no crown that fits everyone. The crown is selected based on where it will be used, strength needs, and personal preference. Let us examine the most common types of artificial teeth utilized today.
Porcelain Crowns
Porcelain crowns are applied because they are natural in appearance. They can blend harmoniously with existing teeth, so they are the perfect choice for replacing front teeth. Porcelain crowns offer perfect solutions for those who are afraid of appearance when having a broken tooth restored.
Porcelain-Fused-to-Metal (PFM) Crowns
PFM crowns put together the durability of metal and aesthetic appeal of porcelain. The metal provides the strength, while the porcelain veneer makes the crown appear like a natural tooth. They are typically employed in crowns and bridges that will last for a longer period.
Metal Crowns
Metal crowns are constructed of gold or other alloys that are very resistant to wear and are extremely durable. They are generally used for molars which need to bear high chewing forces such as biting the food. Although they might look ugly, they are an economically viable option given their lifespan.
Zirconia Crowns
Zirconia crowns are becoming more popular because they have metal-like strength with porcelain-like appearance. They are biocompatible, highly fracture-resistant, and are commonly used for dental bridges and implants.
Temporary Crowns
Temporary crowns are temporary crowns and are a cover until the final crown is cemented. A temporary crown covers the tooth during the procedures such as root canals or implants until the final one is done.
Choosing the Right Dental Crown
Each crown is different from the others and to be utilized differently for every patient. One will be guided by the dentist on selecting the appropriate dental crown and the following aspects are to be taken into consideration.
- Budget: Metal crowns can be thought of as more economical compared to zirconia or porcelain.
- Location of tooth: More durable crowns are sought for Back teeth whereas front teeth demand more cosmetic options.
- Preferential aesthetics: Patients who want natural and beautiful smiles tend to favor porcelain or zirconia.
Multi-Day Process with a Temporary Crown
According to the conventional procedure, getting a crown usually requires two visits:
· Your tooth is begun with an examination and preparation of the tooth, possibly taking X-rays. In some cases, a model of your teeth or mouth is made beforehand.
· The tooth is recontoured by grinding away some of its outer surface to provide room for the crown.
· An impression of the prepared tooth and surrounding teeth is taken.
· A temporary crown is cemented over the tooth to cover and protect it.
· The impression is taken to a dental laboratory where your permanent crown is built—a process that takes from several weeks to months.· Once the crown is prepared, you return for your follow-up visit, when the dentist cements the crown permanently on your tooth.
Same-Day Procedure
For some patients, same-day crowns eliminate the temporary crown and multiple visits:
· The dentist makes use of digital photographs of your mouth.
· The scans are read using a special software, which makes a 3D impression of your crown. The crown is milled in the dental clinic, usually within 1- 2 hours.
· When the crown is ready, it’s cemented in at the same appointment. The entire process typically takes 2- 4 hours.
Certain patients can return to work or regular activities while the crown is being made. This isn’t feasible in all dental offices, though. You should also ask your dentist if same-day crowns are available and how much it costs, especially if you don’t have dental coverage.
