PROSTHETIC CROWN

PROSTHETIC CROWN

PROSTHETIC CROWN

Recently, prosthetic crowns have grown more popular in dentistry since they solve many tooth issues. A broken tooth, missing tooth, or desire for a more attractive smile can be addressed with prosthetic crowns.

1. What is a prosthetic crown? How does it work?

A dentist may propose a prosthetic crown for numerous reasons. Preventing tooth decay is a common reason. Decay, trauma, or a large filling may weaken the tooth. A prosthetic crown helps strengthen and prevent tooth fractures.

A prosthetic crown may also be needed to restore a root canal-treated tooth. Root canals can weaken teeth and increase fracture risk. A prosthetic crown can strengthen and protect the tooth, allowing it to function normally.

To improve tooth look, prosthetic crowns are often employed. An artificial crown can cover and improve the appearance of a tooth that is significantly discolored, malformed, or otherwise cosmetically flawed.

2. What are prosthetic crown benefits?

2.1. Protection and Strengthening

A prosthetic crown protects and strengthens weakened teeth. Crowns can preserve fractured, severely decaying, or root canal-treated teeth from future harm and tooth loss. Bacteria are blocked by the crown, minimizing infection risk.

2.2. Restoration of Functionality

Tooth decay and damage can impair chewing and speaking. A prosthetic crown can restore tooth function, allowing you to eat and speak comfortably. Enjoy your favorite foods and say confidently with the crown, which replaces your original tooth.

2.3. Beauty and Confidence

Discolored, malformed, or large-filled teeth might impact your smile and confidence. Prosthetic crowns increase tooth look and smile aesthetics. A seamless integration is achieved by customizing the crown to match your natural teeth’s color and shape. A better smile will make you feel more confident and ready to show off your teeth.

2.4. Durable Solution

Prosthetic crowns last long. Crowns can solve dental difficulties for years with proper care and maintenance. Crowns endure longer than fillings, which may need to be replaced more often.

2.5. A prosthetic crown

It improves oral health by covering the tooth and improving overall oral health. Crowning a broken tooth prevents decay or infection from spreading to neighboring teeth. Crowns also assist in keeping surrounding teeth aligned.

3. How long do prosthetic crowns last?

Prosthetic crown longevity depends on numerous factors. Though hard to estimate, a well-maintained prosthetic crown can last 10–15 years. Proper care and dental bridge checkups can extend a crown’s lifespan.

The material of a prosthetic crown is crucial to its longevity. Crown materials include porcelain, ceramic, metal, and zirconia. Each material has distinct properties and durability. Front tooth restorations commonly use porcelain and ceramic crowns because of their natural appearance. This type of crown can last 5 to 15 years, depending on oral hygiene and chewing habits.

However, metal crowns, usually gold or silver alloy, can survive decades. However, their metallic appearance may not suit some individuals, especially for front teeth restorations. Although newer, zirconia crowns are firm and natural-looking, making them popular with patients. With careful care, these crowns last 15+ years.

Oral hygiene and dental health can affect a prosthetic crown’s lifespan and material. Maintaining the crown and tooth requires regular brushing, flossing, and dental checkups and cleanings. Bad oral hygiene might cause decay or gum disease, weakening the crown and shortening its lifespan.

Bruxism, or tooth grinding, can also shorten the longevity of a prosthetic crown. Bruxism causes crown wear by applying excessive pressure. A dentist may recommend a nightguard or splint to minimize nighttime grinding and protect the crown.

4. How are prosthetic crowns made?

4.1. The First Exam

The first step in producing a prosthetic crown is a dentist’s exam. The dentist will determine if the tooth needs a crown and if any dental repair is needed before placing it.

4.2. Prepare teeth

If the tooth is eligible for a crown, the dentist will prepare it. A small part of the tooth’s outer layer is removed to make room for the crown. The crown type and tooth condition determine how much tooth structure is removed.

4.3. Impression

An impression of the tooth and adjacent teeth is taken after preparation. This is done by inserting putty-like material into the mouth from a tray. Biting down lets the material record the tooth’s shape and position. The crown is made from this imprint in a dental lab.

4.4. Choice of Shade

The dentist will also help the patient choose a crown color during the session. This ensures that the crown complements the surrounding teeth for a natural look.

4.5. Temporary Crown

The prepared tooth is covered with a temporary crown, while the dental laboratory makes the permanent crown. This temporary crown keeps the tooth functional and attractive until the permanent crown arrives.

4.6. Crown Making

A dental technician makes a personalized prosthetic crown from a tooth impression in the lab. Ceramic, metal, or a mix of both can make the crown. The technician molds the crown for a perfect fit and natural look.

4.7. Placement of Crown

After receiving the permanent crown, the patient returns to the dentist for the final session. The temporary crown is removed, and the permanent crown is tried on for fit. The dentist bonds the crown to the prepared tooth with dental cement. To maximize comfort and function, shape and bite are adjusted.

4.8. Care After Crown

The patient receives prosthetic crown care instructions after the crown is implanted. Brushing, flossing, avoiding hard or sticky foods, and getting regular dental checkups are normal.

5. What are the types of Crowns?

5.1. Metal Crowns

The oldest and most reliable prosthetic crowns are metal. They are constructed of gold, silver, and base metal alloys. Metal crowns are strong and durable, making them excellent for molars and teeth that bite hard. Metal crowns also require less dental preparation, maintaining more tooth structure. However, their metallic appearance may deter those seeking a more natural restoration.

5.2. Crowns made of Porcelain fused to metal (PFM) Crowns

PFM crowns are famous because they blend metal strength with porcelain beauty. The metal substructure of these crowns is coated with tooth-colored porcelain. PFM crowns look more natural than metal crowns, making them acceptable for visible teeth. However, the metal substructure may generate a dark gumline line over time, which may be cosmetically concerning.

5.3. 100% Porcelain Crowns

Dental ceramic all-porcelain crowns seem most natural. Highly biocompatible, they do not cause gum inflammation or allergies. All-porcelain crowns are ideal for front teeth and other conspicuous mouth locations that prioritize aesthetics. They match the surrounding teeth in color, translucency, and texture. But all-porcelain crowns can chip or shatter and are weaker than metal or PFM crowns.

5.4. Zirconia Crowns

A new type of prosthetic crown, zirconia crowns, is solid and attractive. They are made of zirconium dioxide, a strong ceramic. Zirconia crowns are perfect for front and back teeth due to their durability. Their chipping, cracking, and wear resistance is top-notch. Zirconia crowns look like genuine teeth and are quite attractive. However, they require more tooth preparation than ordinary crowns.

5.5. E-max Crowns

The high-strength glass-ceramic lithium disilicate is used to make E-max crowns. These crowns mix smoothly with neighboring teeth because to their translucency and aesthetics. Superior durability and fracture resistance characterize E-max crowns. Strong and attractive, they are suitable for front and rear teeth. Due of its higher wear risk, e-max crowns may not be suitable for severe bruxism.
