Durability of Porcelain Crowns Post


With the advancement of modern cosmetic dentistry into all porcelain crowns from traditional porcelain fused to metal crowns (PFM crowns), many have wondered if the

porcelain crowns would be as durable over the long term. Well, recent clinical studies have shown that they are just as strong and also have the ability to maintain their beauty over time as well.

The main differences in porcelain crowns are the type of porcelain used, and how they are fabricated in a dental laboratory. Different porcelain types and strengths are used for different reasons. Remember also, that a lab created porcelain crown, is of higher fabrication quality and fit, than an in office computer milled crown.

Long Term Study – Porcelain Crowns

The researchers at the Medical University at Innsbruck studied a little over 1,300 all porcelain crowns placed between 1987 and 2009. They were tested for predictability and strength and found to have a high,(93.5% probability of survival) success over a 10 year period. The study was published in the International Journal of Prosthodontics). The study included those with root canal teeth, and those who grind their teeth.

A total of 302 patients (120 men and 182 women) participated in the study. They were examined at the university during regularly scheduled visits for dental examination. Patient-specific data about sex, age, tooth sensitivity, smoking, and grinding  were noted, as well as self-reported data regarding their level of

satisfaction with their restorations: excellent, good, medium, or none. The porcelain crowns were broken down into areas of mouth as well, into front( anterior), and back( premolar, and molar) regions.
All 1,335 porcelain crowns had been placed at the university between November 1987 and December 2009. Of these porcelain crowns, 451 were observed over a 10-year period, 84 for 15 years, and 24 over 20 years.

Dental examinations were completed by two dentists in the spring of 2010. One dentist had placed the majority of porcelain crowns, whereas the other dentist involved in examinations had placed none of them. California Dental Association/Ryge criteria were used to rate each porcelain crowns as a success, relative failure, or absolute failure.

Any porcelain crowns that had severe enough issues to warrant replacement were considered an absolute failure. If a finishing procedure or polishing was able to fix the issue, the porcelain crown was labeled a relative failure.

Of the 1,300+ porcelain crowns in the study, only 95 porcelain crowns were rated as failures, 79% of which were absolute failure. Most failures occurred in the anterior region, with 65, while 19 occurred in premolars and 11 occurred in molars.

Success rates remained strong over time. The estimated survival rate was 97.3% at five years, 96% at eight years, 94% at 10 years, 85.8% at 15 years, and 78.5% after 20

years. Almost half of all porcelain crown failures happened in the first 8 years..

The most frequent reason for failure was fracture,(cracks) of the ceramic, according to the researchers, followed in order by cracks in the ceramic and decay.

Root canal teeth and patients who grind their teeth, had higher failure rates.

Patient responses to questions about satisfaction were very positive. With 96% rating it as excellent and 4% rating it as good. The surprising thing about this study was that even patients with failures thought that porcelain crowns were an ideal dental restoration and would do it all over again.

Porcelain Crowns Conclusion

Porcelain crowns are a proven part of cosmetic dentistry and with continued advances in dental porcelain (like e.max porcelain crowns) these results will be even better into the future. Porcelain crowns are an ideal restoration due to their color, shape, and light reflecting properties. The study just proves that they are a valuable asset to any dental patient’s smile.

The Beauty of E.Max Porcelain Crowns Post

Porcelain crowns have long been the cosmetic dentist’s best friend. They  provide a long lasting, beautiful restoration that is very esthetic.   The cosmetic enhancement uses of porcelain crowns include, changing color of teeth, closing gaps between teeth, fixing teeth that are crooked or crowded, changing shape or size of teeth. Porcelain crowns

are also used to cover and protect damaged teeth, (tooth that had root canal treatment, broken, cracked, large fillings), and to act as a new tooth in the case of dental implants.

Full porcelain crowns, unlike porcelain fused to metal crowns, has translucency.  The porcelain’s translucency allows it to reflect light much like natural teeth. There are many different types of porcelain utilized in many different ways, however, the limiting  factor has always been strength against fracture. E.max porcelain crowns have combined optimum translucency and strength.

What are E.max Porcelain Crowns?

E.max porcelain crowns are a highly esthetic crown originally developed to be used on implants. Dental implant porcelain crowns require greater strength against fracture than crowns on natural teeth. E.max porcelain crowns (due to superior strength) can also be made thinner than other porcelain crowns, allowing for more natural translucency and beauty.  E.max porcelain crowns are made from a single block of lithium disilicate ceramic. This type of porcelain is considered a very high grade material which has been harvested for its toughness, durability and opaque qualities which make for a highly prized crown.

E.max porcelain crowns are considered to be a perfect match against the backdrop of your natural teeth. The transparent color, lifelike shape, along with its light reflection properties create the ideal restoration. There is no metal framework on e.max porcelain crowns which means there is never a chance of a grey line of metal showing through your gums. They are strong, long lasting and unlikely to crack or fracture as compared to many other types of crowns. They are considered to be at less risk of chipping compared to zirconia porcelain crowns.

The beauty of this technology is that e.max is not limited only to porcelain crowns. The same techniques and materials are available for porcelain veneers, porcelain inlays, porcelain onlays, and porcelain crowns over dental implants.

E.max lithium disilicate glass ceramic delivers the fit, form, function, and esthetics demanded by modern cosmetic dentistry but with the enhanced strength and light reflecting properties dentists demand as well. Since the e.max porcelain crown system was introduced almost 40 million restorations have been  and they have been proven effective for use.

 Any Disadvantages of e.max porcelain crowns?

-The main disadvantage of e.max porcelain crowns is with the cost. The lab equipment and highly specialized lab training to make this crown are the reasons why the quality comes with a higher price tag.

-The second disadvantage with e.max porcelain crowns is that it can not be used to make a porcelain bridge, and fusing of  more than 2 teeth is not recommended.

-The third main disadvantage is, as with most porcelain crowns, there tends to be a higher chance of sensitivity after the crown is cemented in place. The sensitivity may last days or weeks.

Conclusion

E.max porcelain crowns have proven to be a very useful cosmetic dentistry tool. Dentists and patients no longer need to compromise when it comes to the esthetic look of the final restorations. You no longer need to worry about crowns looking unnatural. E.max porcelain crowns will give you something to smile about!

What Causes Tooth Sensitivity? Post



Tooth sensitivity is generally the result of worn tooth enamel or exposed tooth roots due to gingival recession. Other causes of tooth sensitivity include tooth decay, a cracked or chipped tooth, a worn filling, or periodontal disease. Tooth sensitivity is a very common problem affecting more than 1 in 8 Americans. For some they are aware and neglecting the problem and for others they think it is normal and try to mask it by avoiding those teeth when it comes to certain food items. When tooth sensitivity is present it becomes difficult at times to enjoy our favorite food and drink or even brush our teeth properly.

What Causes Tooth Sensitivity?

The pain or discomfort you feel when a tooth is exposed to hot or cold temperatures or even an acidic food or drink. This is the hallmark sign of tooth sensitivity. There are 3 layers of a tooth. These are called enamel, dentin, and pulp. The enamel is the harder outer shell that covers your teeth. Tooth enamel is considered the hardest mineral substance in the body. Even stronger than bone. There is one other piece to the puzzle and that is cementum. Cementum covers and protects the root surface where the enamel does not cover. When something happens to the enamel or cementum you end up with tooth sensitivity. The enamel could be damaged thru tooth decay or trauma while the cementum can be lost due to periodontal disease.

Worn Down Enamel. Enamel can be damaged in a variety of ways. These can include overly aggressive brushing, tooth trauma, tooth enamel erosion from acidic drinks, and even teeth whitening products if not used as directed. In areas where the enamel breaks down it will expose the soft underlayer, the dentin. The dentin has tubules that connect to the inner layer the pulp. The pulp is where all the nerves and blood is. This will cause you tooth sensitivity to begin to develop.

Periodontal Disease. This is a progressive disease that triggers an inflammatory response in the mouth. If left untreated it can progress from gingivitis (reversible) to periodontitis (non reversible). Periodontitis will lead to destruction of cementum, gingival tissues, and bone surrounding your teeth. Once the roots of your teeth are exposed, you will develop tooth sensitivity.

Bruxism. Also referred to as teeth grinding. When we grind our teeth we put extreme forces on our teeth. This force can lead to cracks in the enamel on your teeth. Once those cracks form, it exposes the soft dentin beneath leading to tooth sensitivity.

Tips If You Have Tooth Sensitivity

-Softer Toothbrushing. Brushing technique should include use of a soft-bristled brush and use at a 45 degree angle to your gum. this will help prevent damage to your enamel and gum tissues.

-NO! acidic foods and drinks. These will only cause you pain and discomfort if you already suffer from tooth sensitivity. But if you do choose to consume these wait about 30 minutes after bruhing to give you a chance not to feel so much pain or discomfort.

-Slow Down On Teeth Whitening. Teeth whitening can cause temporary tooth sensitivity. If you do develop tooth sensitivity while undergoing teeth whitening treatment speak to your dentist immediately.

How Is Tooth Sensitivity Treated?

Dentistry is highly personalized care. Tooth sensitivity is no different. The treatment for tooth sensitivity will depend on the cause. A proper diagnosis is necessary to develop a proper treatment plan for your tooth sensitivity. Tooth sensitivity treatment can include:

-Use Of Desensitizing Toothpaste. A common over the counter toothpaste is called Sensodyne. This toothpaste acts to seal those tubules present in the dentin. By sealing those tubules, it will remove or diminish the tooth sensitivity you may be feeling. Sensodyne contains, calcium, phosphate, as well as fluoride.

-Fluroide Treatment. This can be done at home or in office. In office, the fluoride will be applied using a tray and applied to your teeth giving adequate coverage. There are also take prescription home rinses that can be used by the patient as needed.

-Custom Fabricated Mouth Guards. This would be used to ward off damage from teeth grinding that can cause tooth sensitivity.

-Restore Broken, Chipped, or Fractured teeth. This can include dental bonding or dental crowns to restore your teeth to a healthier state and prevent tooth sensitivity.

-Periodontal Disease Treatment. This can include bone grafting as well as gum grafts to cover the root surfaces of your teeth that have been exposed.

Root Canal Therapy (RCT). In some cases tooth sensitivity is caused by a dental infection present inside a tooth.

What Causes Tooth Sensitivity? Conclusion

Now you know the causes of tooth sensitivity it is important to address these issues if you have them with your dentist. Be proactive and treat tooth sensitivity before it gets out of control.
