With the movement 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 effective in the long term. Well, recent studies have shown that they are just as strong and maintain their beauty over time as well.

The main differences in porcelain crowns are the type of porcelain used, and how they are fabricated. 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.

Porcelain Crowns Long Term Study

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 recent 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 an asset to any dental patient.

 

Cosmetic Dentistry has evolved over the years to allow dentists to give patients what they crave…..A beautiful long lasting smile that changes their life. In the past, dentists could do minor changes to a person’s smile or more drastic ones using orthodontics. Today, modern cosmetic dentistry techniques and materials allow drastic changes as well as minor ones that can alter a patient’s smile for the better.

Do you believe having a great looking smile can improve your appearance and enhance your social life?

In a recent poll by the American Academy of Cosmetic Dentistry (AACD) revealed that about 96% of those surveyed agreed that it can. In the same study about 65% of the participants said they were unhappy with one or more aspects of their smiles. Cosmetic dentistry has the ability to change that.

Cosmetic Dentistry Procedures

Cosmetic Dentistry procedures come in all sizes from a one office visit for teeth whitening to a multiple visit complete smile makeover. Let’s take a look at some of the most sought after cosmetic dentistry procedures…

-Teeth Contouring. This might be one of the simplest and easiest cosmetic dentistry procedures of all. It is generally done without anesthesia and can be as simple as filing down a tooth that appears longer or is slightly out of alignment with the others. Most patients are quite surprised at how such a small adjustment can alter their smile for the better.

-Gum contouring. Evening out gum levels can help teeth to look more evenly sized and can make short teeth appear longer.

-Teeth Whitening. In the United States, teeth whitening is the most common cosmetic dentistry procedure performed by dentists. It has been proven by research time and again that people find a whiter smile to be more attractive.  People tend to feel better about themselves when they are happy with their appearance. The teeth whitening procedure can be done at home or in the office. Either procedure is generally very successful, and can give patients a dramatic change to their smile with minimal cost and time invested.

-Dental Bonding. While dental bonding is also used to restore teeth damaged by tooth decay it can also be used as a composite veneer to change color or shape, fix chipped teeth, or close small gaps in your smile. Dental bonding is the process in which tooth colored dental materials are bonded to a tooth. This procedure is also a quicker fix and can usually be completed in a single visit easily altering your smile in as little as an hour.

-Replacing old silver restorations. Many of us have a few silver fillings. Replacing silver fillings with new white fillings or porcelain onlays can make your whole smile brighter.

-Porcelain Veneers and Porcelain Crowns. Our smiles are constantly changing over time with wear. Teeth can get worn down, can shift, or maybe you were born with an imperfect smile. Porcelain veneers and porcelain crowns can be a great way to replace lost tooth structure and alter imperfect teeth. These cosmetic dentistry procedures tend to require multiple visits but the results will give you a beautiful smile. Porcelain

Veneers are custom made, ultra thin, tooth colored shells that are adhesively bonded to the teeth. This allows the cosmetic dentist to not only alter color of your teeth, but shape and length as well. Porcelain veneers are sometimes called instant orthodontics. This is because porcelain veneers can change the alignment of teeth if the alignment issues are not too extreme. Porcelain crowns can be used on teeth that either already have crowns or need more extensive work (having large restorations or tooth decay). Both porcelain veneers and porcelain crowns can as used in cosmetic dentistry to give the patient a flawless, more youthful and sexy smile.

-Dental Implants. These are the newest addition to cosmetic dentistry. Dental implants allow cosmetic dentists another option in tooth replacement. Whether it is a singleCosmetic Dentistry Marielaina Perrone DDS tooth or a full mouth restoration, dental implants can fill that need. Missing teeth has long been considered a sign of old age. Having a full set of white teeth screams youth especially when they are bright, white, and sparkling. When a person is missing a tooth they have several options. There are partial and complete dentures (including the all on 4 dental implants system), traditional bridges, and dental implants. A dental implant can look and feel just like a natural tooth. It is also easier to keep clean than a traditional bridge. Dental implants are placed directly into bone creating a solid foundation for a natural tooth replacement.

-Bite Reclamation. Over time as we use our teeth we tend to lose some height on our teeth. This loss of height of height is also referred to as loss of vertical dimension. Some other factors that cause this loss include acid reflux or teeth grinding (bruxism). Reclaiming a person’s bite utilizing dental implants and porcelain crowns will increase vertical height which will also remove some of the wrinkles around the mouth. These wrinkles develop as our we age and our mouth’s sag from this loss of dimension. Cosmetic dentistry can fix some of this.

Cosmetic Dentistry Conclusion

Cosmetic Dentistry gives the dentist the ability to give patients the smiles they have always dreamed of. Not everyone wants a complete Hollywood style smile makeover and just want minor issues fixed that have always bothered them. Modern cosmetic dentistry allows for both minor fixes as well as extreme ones. Whichever cosmetic dentistry procedure you choose, please be sure that you keep your teeth healthy by visiting your dentist regularly for dental examinations and professional cleanings.

Cosmetic dentistry includes a number of dental procedures aimed at improving the appearance of the teeth and smile.  A very common cosmetic procedure is the dental veneer.

Dental veneers are wafer thin, custom fabricated shells of tooth colored materials designed to cover the front surface of teeth to improve your overall smile and appearance. These custom fabricated shells are adhesively bonded to the front of the teeth. This allows the cosmetic dentist the ability to change your teeth’s color, shape, size, or length.

Dental veneers can be fabricated from dental porcelain or from composite (resin) materials. Dental veneers can be used to create bright, white smiles with beautifully aligned, shapely teeth. Dental veneers also protect the surface of broken or damaged teeth, and may eliminate the need for more extensive treatments. Other advantages of dental veneers include durability, an improved smile, and the need for much less tooth structure removal compared to traditional or porcelain crowns.

Why are Dental Veneers Needed?

Dental Veneers are utilized for a variety of reasons in cosmetic dentistry. These reasons can include:

-Crooked Teeth. Some minor modifications can be done, which may eliminate the need for orthodontic movement.

-Genetics. Certain people are born with abnormal sized/shaped teeth, or gaps between their teeth that widen with age.

-Wear and Tear.  Teeth wearing down is a natural part of aging. Aged teeth are more likely to be small,  have chips, fractures, cracks or a generally uneven appearance.

-Worn Enamel. Over time, the thin, hard translucent substance covering your teeth (enamel) may become worn, see through,  dull, or discolored. Such wear and discoloration may be natural or result from a genetic predisposition. However, it often results from consuming soft drinks, tea or coffee, smoking, using certain medications, etc.

Material Used for Dental Veneers

The most commonly utilized materials for dental veneers are composite resins and dental porcelain. Porcelain veneers are the more appropriate answer for severe cases involving dullness, wear, tooth discoloration, extensive chipping, cracking, gaps in teeth or uneven teeth. Composite bonding or just dental bonding is an inexpensive, effective and minimally invasive way to restore and correct small chips, cracks and discoloration in the teeth. Porcelain veneers generally require some reduction of the enamel tooth surface, while bonded dental veneers can oftentimes be done without tooth modification. Porcelain veneers are very strong, and do not change color. Bonded veneers tend to chip and pick up stain over time.

Techniques Used in Dental Veneers

Indirect Technique – This technique means that the composite or porcelain veneers are fabricated outside the mouth by a dental technician in a laboratory.

Direct Technique – This technique means that the composite veneers are created directly on your teeth by your dentist during your appointment.

When are Veneers Good Treatment?

The removal by a dentist of any natural tooth structure is permanent, so modern cosmetic dentistry has moved to offer patients the most minimally invasive options first. If your natural teeth are functionally and cosmetically adequate, dental veneers may not be the right treatment for you.

On the other hand, if you have any of the aforementioned cosmetic issues, your treatment options may  include veneers. Dental Veneers do have the advantage of a proven ability to enhance the appearance of the mouth, smile and other facial features that are better supported by properly shaped teeth.

If modification of the tooth surface is necessary to achieve optimum results, some cosmetic dentists will recommend less invasive alternatives to dental veneers. One such alternative would be, teeth whitening for people with mildly discolored teeth who only want a whiter and brighter smile. If crooked teeth or alignment issues are involved, the teeth whitening alternative may also be combined with orthodontic treatments. Invisalign, full braces, or use of an orthodontic appliance for minor tooth movement may be all that you need to acquire the smile you desire.

Care of Dental Veneers

Care must be taken not to abuse dental veneers because the wafer thin porcelain shells or composite layers can be damaged or break. Your dentist may advise you against grinding, fingernail chewing, and biting directly into things such as carrots or pizza crusts. If you grind at night your dentist  may recommend you wear a night guard while sleeping. It is even more important to have excellent dental hygiene, so that you do not get tooth decay forming under your dental veneer. You should also see your dentist for regular cleanings.

Dental Veneers Conclusion

Dental veneers, whether porcelain veneers or composite veneers, are a great option for those who wish to change their smile. Dental veneers give the cosmetic dentist and patient the ability to change color, shape, and size in an easy manner. As always, before pursuing dental veneers of any kind, please have a thorough dental examination and professional cleaning performed to ensure your mouth is healthy and able to withstand the new treatment.

 

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!
