Bruxism (also called teeth grinding) – is the habitual, involuntary grinding or clenching of your teeth, usually during sleep, but can also occur during the day. The cause of bruxism is unknown but it is often associated with anger, tension, fear, frustration, and stress.
Many people go through periods in their lives where they grind their teeth or clench them from time to time. Bruxism generally does not cause any long term damage when done occasionally. If the problem persists, over time there will be long term damage to the teeth and surrounding tissues in the mouth.
When Does Bruxism Occur?
Bruxism generally occurs during sleep, most people are unaware that they are even grinding or clenching their teeth unless they are told so by their partner or by their dentist . There are signs that should give you pause to think that you may be a bruxer. Usually it is a loved one that notices the grinding as it awakens them at night. Another sign is a dull, constant headache or sore jaw when waking in the morning. Cracked, chipped teeth, and wear facets may be noticed by your dentist. Continuous teeth grinding will lead to dental issues, which can result in fracturing, loosening, or loss of teeth. Habitual teeth grinding will wear the teeth down, remove the cusps on the teeth,and essentially flatten them. When these issues happen, bridges, crowns, root canal therapy, dental implants, partial dentures, and even complete dentures may be needed. Bruxism can also lead to Temperomandibular Joint Disorder, hearing loss, and even change the appearance of your face.
Treatment Options For Bruxism?
Unfortunately, there is no cure for bruxism. The only way to truly get it under control is to learn to manage stress in our lives better. So what can a dentist do to help? Luckily, dentistry has developed some techniques to protect our teeth from bruxism.
Treatment options include:
-Fabrication of a Custom Mouth Guard. This will act as buffer to protect your teeth during sleep. It does not necessarily cause the bruxism habit to stop, but does protect the teeth from damage.
-Prescription for Muscle Relaxants. This can allow relief from tight muscles surrounding the face.
Other tips to help you stop bruxism include:
-Avoid or cut back on foods and drinks that contain caffeine.
-Avoid alcohol. Grinding tends to intensify after alcohol consumption.
-Do not chew on pencils or pens. Avoid chewing gum as it allows your jaw muscles to get more used to clenching and makes you even more likely to grind your teeth.
-Attempt to train yourself not to clench or grind your teeth. If you notice that you clench or grind during the day, re-position the tip of your tongue between your teeth, or wear a daytime soft guard on your lower teeth. This practice trains your jaw muscles to relax and also is a mental cue for the brain to stop grinding your teeth.
-Relax your jaw muscles at night by holding a warm wash cloth against your face in front of your earlobe.
New Treatment Option For Bruxism
In the past, once damage from bruxism reached the point of needing a full coverage dental crown both dentist and patient understood the treatment would see limited success. This is because of the strength of traditional porcelain crowns or porcelain fused to metal crowns was not up to the task of dealing with the extra forces over the long haul. Recent technology advances in dental materials have allowed the development of a new type of crown called the BruxZir crown.
BruxZir Solid Zirconia is a monolithic solid zirconia restoration with no porcelain overlay. This type of crown when used in patients with bruxism offers a long term restoration built to last. It is virtually chip proof, making it an ideal restoration for patients with bruxism. BruxZir crowns can even be used over a dental implant.
Bruxism can be a terrible habit with the develoment of long term issues. While no known cure exists, dental materials advancement has allowed the dentist to maintain the health of your teeth under the extreme pressures and forces of bruxism. Visit your dentist regularly so bruxism can be diagnosed as early as possible to ward off potential issues.
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.
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
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.
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!
Porcelain crowns have been a staple in cosmetic dentistry for years. It gives the dentist and patient a much more aesthetic appearance as a final product. In the past crowns and bridges were traditionally made of porcelain fused to metal (PFM). With the development of modern porcelain, which are incredibly strong and reflect light similar to natural teeth, full porcelain crowns can be used in most areas in which porcelain fused to metal crowns were used. This is especially true in a cosmetic area of the mouth.
Porcelain crowns are very versatile and used in many ways. The cosmetic enhancement use 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 has a root canal, broken, cracked, large fillings), and to act as a new tooth in the case of dental implants. Their versatility gives the dentist 89014 a greater flexibility in using them to fix potential issues for the patient.
The first step often times includes impressions for study models and photos. The patient and dentist can then discuss and plan what the end result should be. The treatment includes preparation of the tooth surface for the porcelain crowns. The outer enamel and sometimes a bit of the dentin are removed. This allows room for the porcelain crowns to fit over the teeth and be in perfect cosmetic alignment with the others. Impressions are taken of the newly reshaped teeth and temporary crowns are made. The porcelain crowns are custom made in the dental laboratory. The porcelain crowns are then cemented or bonded onto the teeth using an adhesive bonding material. The placement of the porcelain crown will normally take about 30 minutes (depends on amount of porcelain crowns being placed). Once completed, the patient can eat normally and enjoy the benefits of a beautiful new porcelain crown that matches and blends perfectly with the patients existing teeth. Only you and the dentist should know anything was done.
Advantages of All Porcelain Crowns
-No PFM gray or black lines at the Gum Line of Teeth. You may have noticed a person with a dark line in the gum area along a PFM crown edge. With PFM crowns, the soft tissue around the tooth can recede over time. This allows a reveal of the metal framework underneath. This cannot happen with an all porcelain crowns because they are metal free.
-Perfect Fit. Porcelain crowns are created in state of the art facilities. Porcelain crowns will fit so well you will even forget they are present.
-Cosmetically Perfect Match. All porcelain crowns have the ability with modern porcelains to match your existing shade of tooth color as well as mimic the light reflecting properties of your natural teeth. Porcelain crowns will be undetectable to anyone but you and your dentist. Dental porcelain can be shaped custom colored and sculpted to closely copy the look of your own natural tooth enamel. All the while providing the desired strength and resilience.
Some disadvantages of an all porcelain crowns:
-Higher cost over traditional PFM crowns.
-Durability. While porcelain crowns are very durable, they do not have the flexibility of natural teeth, they can fracture. Avoiding certain foods may be necessary. For example, Biting into sandwich with a hard bread. Patients who grind and clench their teeth will need to be fitted with a mouth guard to protect the porcelain crown from unnecessary and excessive pressures.
-Porcelain crowns may need a bit more reduction of tooth structure than traditional PFM crowns.
-Sensitivity may happen for a short time, (hot, cold sensitivity), especially with bonded porcelain crowns.
