Types of Dental Crowns

The dentists play a major role in maintaining good oral health for their patients. Apart from regular teeth cleaning, bonding and cavity filling procedures, they offer other complex procedures. That includes the root canal, wisdom tooth extracts, and dental crowns. The dental crowns are made in many forms. They offer a good alternative for people with missing or weak teac. The following are the functions the crowns serve.

Dental Crowns

The dental crowns are also known as the cap. A crown is a prosthetic object. The dentists cement it on the tooth. After being placed on the teeth, it can only be removed by the dentist. The cap is used by the dentists to cover a damaged tooth. The covering improves the appearance of the tooth and strengthens it. Here, it aligns with the damaged tooth on the jawbone.

Crowns are made on demand. The dentist must ensure that its color resembles the natural teeth of the patient. That is very important since it prevails people from detecting if the patient has crowns. The size of the damaged tooth is reduced to enable the crown to fit on it properly. After that, an impression of that tooth is taken to create a crown. The dentist can place a temporary crown while making a permanent one.

Types of dental crowns

There are four types of dental crowns. They include:

Ceramic crown -The ceramics are perfect for restoring missing or damaged front teeth. They are a perfect choice since they can easily blend with the natural tooth color. The particular crown is made from porcelain.

Porcelain fused to the metal crown -This crown has a stronger bond than the regular porcelain. That is because it has been connected to a metal structure. The metal makes this crown more durable.

Gold alloys -This crown is a mixture of copper, gold, and other metals. The crown offers a very strong bond to the tooth. It does not fracture or wear the tooth. That is why it is very durable. The golden color makes it stylish too.

Base metal alloys -It consist of metals that make up a very strong crown. These metals are highly resistant to corrosion. Before fitting the crown, the least healthy tooth is bought to be removed.

Differences between the crown types

· The filling materials and strength of the tooth affect the sealing capacity of the porcelain crowns. The other three crown types provide a better seal against damages.

· The gold and metal alloys crowns are highly durable compared to porcelain crowns that are less strong. They may damage the tooth when grinding the teeth. However, the porcelain that is fixed with metal is more durable.

The crowns may get loose and fall out sometimes. However, if they are properly maintained, they can last for a very long time. Practicing good oral hygiene advances their durability.

Dental Crowns – The Basics

What are dental crowns?

Dental crowns or teeth crowns are one of the commonly advised dental procedures for severely declined teeth. Commonly known as a cap, the crown is a tooth-shaped cover, which is placed over the damaged tooth. The procedure is referred to as dental crown procedure.

Why is it necessary?

The teeth are an essential part of our digestive system, which helps grind the food we eat. Teeth decay affects the strength of the teeth, and necessitates procedures such as fillings or teeth crowns, to strengthen the affected teeth.

What are the types of crowns?

Teeth caps are available in different forms and are generally formed in the dental lab, according to the tooth shape and size. These are made from different materials such as metals (gold, nickel, or chromium), resins and porcelain (often referred to as ceramic dental crowns). While metallic ones require less tooth trimming for the crown placement, they may not be suitable for the front teeth because of their metallic appearance. Porcelain ones on the other hand, can be matched to your teeth color, and are hence preferred over the metal caps.

What is tooth trimming?

Talking about tooth trimming, it is one of the most essential steps of the dental crown procedure. This involves reducing the width and height of the tooth that is selected to receive the dental cap.

What is the procedure?

During the crown procedure, the dentist trims your teeth using a drill. This may be done under local anesthesia, if you feel any pain or sensitivity during the procedure. The next part of the procedure is taking an impression of the trimmed tooth. A cast or a plaster model of the impression is then prepared and sent to the lab for forming the teeth cap. Once ready, the dentist fixes it with a special cement to ensure that it remains fixed.

How many days does it take?

Dental crown procedures often require 2 to 5 sittings, based on the amount of tooth destruction.

How much does it cost?

The cost of teeth crowns are mainly based on the type of the material and the number of units required. The cost may also vary in different regions.

How long does it last?

Once placed, the dental crowns may last for six months to 15 years based on the type of material used. Along with restoring the affected teeth, they can also be used to replace missing teeth. These are then referred to as a bridge.

The dental crowns have theseby become an essential part of the teeth saving procedures commonly followed by dentists all over the world.

Dental Crowns: Benefits, Risks and Candidacy

If you have a tooth or teeth that have become severely damaged or decided, it is important to restore their structure, strength, and function to improve your facial & smile aesthetics and boost your confidence. The dental crown procedure can be a great solution for patients with weakened or traumatized tooth / teeth.

Cosmetically, dental crowns are tooth-shaped, natural-colored coverings applied over the tooth's surface to restore its shape and size, strength, hide surface imperfections and / or rejuvenate the tooth's appearance.

Benefits

Today porcelain, ceramic, and porcelain-metal mix dental crowns, offered at most aesthetic dental clinics, are custom matched to the color of your existing teeth and are specifically designed for your smile in order to provide the most accurate, aesthetically pleasing results.

These ceramic restorations, when cemented into proper place, encase the entire misshapen or severely discolored teeth, thereby giving you a bright and sparkling smile.

Dental crowns are used to cover dental implant to comfortably work together with your existing natural teeth.

They also act as a protective cover, protecting a weak tooth from further damage or to hold together parts of a fractured tooth.

One of the most obvious advantages is that this capping of the tooth looks, feels, and functions like your natural teeth and restores your overall bite strength, thereby improving your ability to bite down comfortably.

If crafted accurately, a dental crown can help your upper and lower teeth to meet properly and maintaining a proper, balanced bite.

Risks

The risks associated with the placement of dental crowns include an increased sensitivity to heat and cold. Since your newly crowned tooth still has a nerve in it, you may experience sensitivity to cold and hot temperatures on the tooth following crown placement.

Nerve damage is another potential risk associated with this procedure. The preparation of the tooth for a crown can lead to dental nerve damage. In this case, the complete removal of dental nerves (root canal therapy) is unavoidable.

Other common risks may include loosing of crown or the loss of a crown. Loosening of crowns can be caused by a deterioration of the dental cement used to attach the crown to the abutment.

If the crown is not fitted correctly to your tooth, bacteria can easily grow between a space in the tooth and crown and further decay of the tooth under the crown may develop. Crowns may become so loose that they fall off.

Porcelain-metal mix crowns may fracture, chip or break, needing the crown replaced with a whole new crown.

Other possible complications may include risk of the carious infections, gingivitis, bleeding around the site of the crown placement and reactions to anesthesia used to numb the tooth and surrounding tissues during the procedure.

Candidacy
Dental crowns are a good option to consider for patients whose tooth has sustained some damage. It is also an ideal solution to yellow or discolored teeth.

Dental crowns also serve as an alternative to pulling the loose, chipped or cracked tooth or replacing it with a prosthetic tooth.

Patients who grind their teeth, are unable to comfortably chew food or / and which bite is not aligned properly can benefit from dental crowns.

Patients who have undergone a root canal will need a dental crown. People with an especially large dental filling may need a dental crown to preserve their major tooth.

Those who have lost their teeth to a traumatic injury or periodontal disease can have crowns together with dental implants or dental bridges.

Most importantly, dental crowns may only be recommended when the patient has a healthy dental structure and gums to support the crown. Healthy gums anchor crowns firmly in place and ensure most effective cementation of the crown.

Mini Dental Implants and Fixed Crowns For Treating Congenitally Missing Maxillary Incisors

Dentists have struggled over the years to treat this condition employing a number of techniques. Removable partial dentures, conventional fixed partial dentures, Maryland Bridges and conventional dental implants are employed with varying degrees of success and patient satisfaction. This article will focus on the benefits of using Mini Dental Implants with fixed crowns to treat such conditions.

Patients with congenitally missing maxillary incisors are often treated in their childhood. Orthodontics is typically employed and completed resulting in an unavoidable facial concave defect in the maxilla and converging adjacent root tips. Correspondingly, this space is missing both in buccal-lingual and a mesio-distal dimensions. The facial concavity may be treated successfully by block only grafting with fixation but the incorrect roots remain problematic. Also, the block grafting requires multiple surgeries, donor site morbidity and considering the patient age and growth potential may be premature. This procedure is best treated by a practitioner with significant skill usually requiring referral.

This complicated treatment also increases the treatment cost. When compounded by consequent implant placement, second stage surgeries and restorative visits, the teenage patient and parent will most certainly object and begin looking for an alternative. Although we are justified to charge for our time and efforts, implant alternatives do exist that are predictable and cost effective.

Mini Implants have been demonstrated to function well in fixed applications. The MDI has allowed us to offer a more affordable solution to patients. The price of the implant parts are reasonable, often under $ 100. Conventional crown fabrication or CAD / CAM may be used without expensive abutments or transfer pieces.

Placement of the MDI is completed following the same general protocol as used for denture stabilization. A Max thread MDI is used to achieve initial stability and a longer implant is recommended. Using the same concepts for placement of large diameter implants, appropriate radiographs and surgical /orative guides are prepared. Placement is accomplished with the use of surgical guides and guide tool devices. Temporaries are fabricated with resin. Impressions may be made at the time of placement or may be reserved for a post operative appointment following osseointegration. Temporary crowns are cemented. Final crowns placed.

Dental Crowns or Dental Implants

So you've had some dental issues and are going to have to choose between getting a dental crown or a dental implant. How do you decide which is better for you?
Dental implants are typically used to replace an entire tooth, and dental crowns are typically used if some part of the tooth and the root are still viable but need to be turned off in order to function properly.

If you have a missing tooth, implants are probably the best way to go, however if you have a tooth that is simply decayed and may not have to be completely replaced, a dental crown may be an option.

Dental implants

For decades dentists used to go with individual crowns or multi-pieced bridges to repair damaged teeth. In the past 25 years or so the dental implant has become much more popular for many reasons.

The benefits of dental implants are numerous:

• Implants protect other teeth
• An implant can replace just a single tooth
• Implants require little maintenance
• Implants look like a natural tooth
• Implants will not slip, therefore make eating more natural
• Implants are more cost-effective in the long run

Implants do not put any strain on other teeth since they are placed individually. Implants are anchored to your jaw bone with a titanium screw with a small fake tooth (called an abutment) on top, followed by a crown that looks and feels like a natural tooth.

Implants do not decay, and because of the ease of flossing and cleaning the implants, the gum tissue and underlying bone are likely to stay healthy as well.

Although the cost of a single implant will likely run from $ 3,000 to $ 4,500, they are also likely to last your entire lifetime. Weigh that against the cost of repeatedly replacing crowns, along with the time you'll spend and any possible pain you'll end, and you will likely come out ahead many ways with the implant.

Dental bridges and crowns

Dental bridges and crowns have their own advantages, the main being that you can salvage your own tooth root and partial tooth, therefore they do not require surgical intervention and probably surgical referral that an implant would.

Another advantage is the time you will spend having the procedure done. Bridges and crowns can be fashioned in two to three dentist visits. The first visit requires the dentist to diagnose the amount of decay to the tooth and then remove the decay and seal off the unfinished tooth with a temporary cap. A following visit will likely either be placing the permanent crown, or making a mold where the permanent crown would then be placed at a follow-up visit.

Porcelain or ceramic crowns and bridges can be colored to match the teeth surrounding the area where they will be placed, optimizing their appearance to be as natural as possible. Other materials used to make crowns include gold and metal alloys and acrylic. These other materials will not match your natural teeth, however they are generally stronger than porcelain and may be recommended to replace back teeth.

Caring for your dental crown is similar to caring for your normal teeth. The crown will need brushing, flossing and will be checked at your regular dental check-ups. Crowns are also not immune to being chipped or damaged by anything that can damage your real teeth.

Even with multiple visits, a bridge or crown cost less than an implant. However, be prepared to have to replace the bridge or crown every 10-15 years due to normal wear and tear.

No matter which option you choose, taking care of your dental hygiene is a must. An implant, bridge or crown can lose its support if the teeth or bone holding it in place are damaged by dental disease. Keep your gums and teeth healthy by brushing with fluoride toothpaste twice a day and flossing daily. Also see your dentist and hygienist regularly for checks and professional cleanings.
