Composite Restoration Techniques

Posted in Cosmetic Dentistry by UK Dental Tourism on February 26, 2010
Tags:

Dental composite resins are types of synthetic resins which are used in dentistry as restorative material or adhesives. Synthetic resins evolved as restorative materials since they were insoluble, aesthetic, and insensitive to dehydration and were inexpensive. It is easy to manipulate them as well. Composite resins are most commonly composed of Bis-GMA monomers or some Bis-GMA analog, a filler material such as silica and in most current applications, a photoinitiator. Dimethacrylates are also commonly added to achieve certain physical properties such as flowability.

Composite restoration requires proper treatment planning and an appreciation of restorative principles. Artistic ability and scientific knowledge produce esthetic, strong, long-lasting restorations. Artistic placement of the appropriate composite material replicates the appearance of natural tooth structure.Scientific knowledge incurs proper tooth preparation, composite selection, and techniques to produce long-lasting restorations.A dentist must know smile design, color, tooth color, position and shape, esthetic goals, and composite techniques. Composite techniques include tooth preparation, bonding, material selection, placement, and finishing techniques. Composite is used for class I, II, III, IV, and V restorations, surface defects, composite veneers, peg laterals, diastema closure, papillae loss, composite crowns, onlays and inlays, tooth splinting, the appearance of tooth rotation and tipping, congenital defects, porcelain repair, composite repair, tooth replacement, implant access closure, and periodontal splinting. Composite corrects lost tooth structure as well as tooth position and color, including craze lines, decalcifications, fillings, discolorations, stains, dentin exposure, cavities, tipping, rotation, crowding, tooth loss, diastema, intrusion, extrusion, chips, cracks, abrasions, attrition, wear, surface defects, surface texture, gingival contours, and developmental defects.

*The importance of layering enamel and dentine shades and how to use the various systems. The composite refracts light differently to enamel and so the restoration must be dentine heavy to appear natural.

*Bond should not be used on instruments to stop the composite sticking because it seriously impairs the quality of the composite and makes it pick up stain. However there are wetting agents available designed for this purpose… though using nothing is still the best. Gentle pats are required to maneuver the composite.

*The best bond strengths are still made with 4th generation bonds. This means separate etch, primer and bond is still the way forward

*By polishing cavities before restoring and rinsing with chlorhexidine  bond strength can be improved.

*Flowable composite can be used to seal cavities and avoid air inclusions on delicate areas which are hard to place composite.

*Teeth are not supposed to be smooth or flat. Use polishing burrs or brushes instead of flat discs.

*The importance in posterior work to avoid curing composite between 2 walls at it places husge stresses on the teeth. It is much better to work in triangles.

*Wedge teeth before preparing cavities (and gradually insert it further as you work)  as this makes restoration easier and will allow a tighter contact.

*Use  a customized matrix for anterior composite work.

Can Implant Be Placed Immediately After Extraction ?

Every patient always wants his or her teeth right away but we really should weigh the risks versus benefits of this procedure.Immediate teeth work best for teeth in the front of the mouth.  It also works very well if you are missing all your teeth and is most successful if you are having implants for your whole lower jaw. Obviously,if its front tooth, some sort of replacement has to be made right away. The first replacement is usually temporary in nature, either a temporary bridge or a temporary one tooth denture. If it is a back tooth that is extracted often initially no replacement is required immediately post extraction.

Implant replacement teeth are the most ideal type of replacement assuming a patient is a good candidate for one. Although some extraction sites receive immediate implants on the day of an extraction, most do not. Patients have a big role in the success of this awesome procedure. They have to  be committed to a soft diet for about 3 months. Even though a tooth is made on the immediate, same day implant, it still has to fuse to your bone. This is called “osseointegration.” If patient can’t commit himself to this, immediate loading or immediate temporaries are not the ideal choice. All of the implants can fail.

These days many extractions receive bone grafting at the time of the the procedure. This grafting material is intended to stimulate bone re-growth and will tend to preserve the bone in the socket afterwards.Most of the specialists seem to feel that the ideal time for placement after an extraction with bone grafting is three to four months. They feel that after three months the bone grafting material is being actively replaced with new bone and this ‘active new bone’ is ideal to receive an implant.

Some of the important factors in determining if immediate loading can be done are:

* Bone density
* Amount of bone
* Initial stability of the implants
* Shape and type of gum
* Implant design and type
* Your bite

Of course implants can and do successfully get placed after more time has elapsed, but after an extraction, the bone tends to continue resorbing for the first year or two. The result of waiting too long can be a site that becomes too narrow to place an ideal sized implant.Bottom line…. immediate dental implants are great in the perfect situation. Pre-surgical planning and expert execution of the procedure makes all the difference.

Good Oral Hygiene Effects General health

Oral health is integral to general health, and quality of life, psychologically by influencing how they grow, enjoy life, look, speak,chew, taste food and socialize, as well as affecting their feelings of social well-being. Manifestations, which are often the first signs of the disease professionals may be the first to discover them and recommend further medical assessment. Furthermore, certain systemic conditions can have direct negative effects on the oral cavity. Oral diseases share common risk factors with the four leading chronic diseases – cardiovascular diseases,cancer, chronic respiratory diseases and diabetes — including unhealthy diet, tobacco use, and harmful alcohol use. Poor oral hygiene is also a risk factor.

Uncontrolled diabetes
Diabetes especially has oral health implications, and can lead to changes in the oral cavity. Poor glycemic control in diabetics is associated with gingivitis and more severe periodontal diseases.

Oral signs and symptoms of diabetes can also include a neurosensory disorder known as burning mouth syndrome, taste disorders, abnormal wound healing, and fungal infections. Individuals with diabetes may notice a fruity (acetone) breath or frequent dry mouth, which can also lead to a marked increase in dental decay. Patients with chronic respiratory diseases who use inhalers also have higher risk for oral fungal infections and chronic respiratory diseases

Chronic respiratory diseases:
Systemic diseases, and the medications used to treat them, often cause adverse oral side effects, such as reduced salivary flow, altered senses of taste and smell, jaw and facial pain, overgrowth of the gums, bone loss and mobility of teeth.Also, numerous medications cause dry mouth, which leads to an increased risk for cavities.

Diabetes can weaken the body’s resistance to infections, and high blood glucose levels in saliva can help bacteria to thrive. Therefore,uncontrolled diabetes and uncontrolled gum disease enhance one another. Diabetics have about twice the risk for periodontal disease as healthy patients, and almost one-third of people with diabetes have severe periodontal disease.Inflammatory periodontal disease can also be a predictor of death from ischemic heart disease and heart attacks in patients with diabetes.

Heart Disorders:
Additionally, periodontal disease has been identified as a risk factor for such conditions as heart disease and rheumatoid arthritis, perhaps through a pathway of increased systemic inflammation.Not many people are aware of recent research that associates heart disease and even strokes with poor oral hygiene. A lax regime in oral care leaves the blood low in Lipoproteins, research shows that this disorder is a leading factor in hardening of the arteries. Every dentist has an advisor on duty, and they are there to prevent problems rather than push up the bill. Bad oral hygiene kills off the good part of High Density Lipoprotein (HDL) and Low Density Protein (LDL), both of which serve to carry naturally produced proteins from one organ to another. If the proteins aren’t absorbed by their receptacle organ then the organ will experience problems, This leads to many of the diseases which together can cause a heart attack. All this can be prevented by spending a little more time on brushing, flossing and making sure that our gums are healthier.

Cancer:
Oral and pharyngeal cancer is the sixth most common malignancy reported worldwide and one with high mortalityratios among all malignancies. The global number of new cases was estimated at 405,318 about two-thirds of them arising in developing countries. Highest rates are reported in South Asian countries such as India and Sri Lanka. The Indian sub-continent accounts for one-third of the world burden.In the USA alone, 30,000 Americans are diagnosed with oral or pharyngeal cancer each year.

How for Maintaining Good Oral Health

* Drink fluoridated water and use fluoride toothpaste.
* Take care of your teeth and gums.
* Thoroughly brush with a soft toothbrush twice a day and floss to reduce dental plaque and prevent gingivitis.
* Visit a dental provider regularly.
* Eat wisely – avoid snacks with sugars and starches and limit the number of snacks eaten throughout the day. Also, eat the recommended five-a-day helping of fiber-rich fruits and vegetables.
* Individuals with diabetes should work to maintain control of their blood sugar; this will help prevent the complications of diabetes, including an increased risk of gum disease.
* Avoid tobacco and limit alcohol.

One Hour Teeth Whitening In Shimla

Discolored or badly stained teeth can be very embarrassing and cause the patient to be very anxious and self-conscious about their appearance. It can make people very reluctant to open their mouths or smile in public and be the underlying cause of self-esteem issues and even depression. But with modern cosmetic dentistry there is a solution to having discolored teeth.

Teeth whitening has existed for many years but in the past has been hit and miss at best and often prohibitively expensive. But as more and more dentists offer the treatment and more patients use it the price is dropping and the treatment becoming more available. New whitening treatments are hitting the market each year, each promising new and improved whitening that takes less time and yields better results.

Whitening works in two ways. Firstly, the teeth are cleaned, removing any material or stains that can be cleaned to make the teeth seem whiter. However, many stains occur when foodstuff or liquid penetrate the enamel of the tooth. This cannot be removed by cleaning but can be bleached white using hydrogen peroxide gels. Although these kinds of bleaching kits are available to buy in shops or on the internet, dentists advise that you always have whitening procedures carried out in surgery. This is because the hydrogen peroxide can be dangerous to soft tissue when used in high concentration. Dentists will be able to use the necessary safety equipment to avoid any contact with soft tissue.

This may often involve the manufacture of a custom made bleaching tray designed to fit exactly over the patient’s teeth, applying the active gel to the required area but keeping the soft tissue safe. These bleaching trays can also be used for lower concentration treatment at home, often worn over night for maximum contact with the teeth. The peroxide filters into the tooth enamel bleaching it white and making the teeth look a healthy and natural white. Tooth whitening is available in many different formats as there are many treatments available and will be more effective for some than others but ultimately it will lighten teeth and make them appear more healthy.

Teeth whitening can be one of the most successful and dramatic cosmetic dentistry treatments, capable of completely transforming the teeth and restoring the self-confidence of the patient. If you suffer from discoloration or staining, ask your dentist about teeth whitening and really give yourself something to smile about.

Having straight teeth is fundamental to having a beautiful smile. For many of us not blessed with naturally straight teeth there is the option of orthodontic teeth straightening.If you have suffered from the negative effects on your self-esteem and happiness from uncomfortable or irregular teeth and jaws, braces can help to turn your hidden smile into a stunning straight grin, using a variety of options.

The need for properly aligned teeth and jaws goes beyond simple aesthetic appeal, providing the individual with an effective bite, chew and fluency of speech, all contributing to your sense of comfort and happiness. Straight teeth also help to prevent physical health problems in the future, maintain healthy gums and improve your facial profile.  If you have been reluctant to undergo treatment due to the anticipated effect on your appearance whilst wearing braces, types of brace exist including invisible, clear and lingual braces to minimise the visual impact on your face, leaving you free to achieve the look you want in the most discrete way possible. Whilst some braces exist that can be removed at regular intervals, others such as lingual braces, can be constructed around the backs of your teeth, keeping them out of sight and mind. The comfort to your mouth can also be maximised with modern fastening methods for arch wires creating minimum irritation to your cheeks and gums.

With recent advancements in the field of orthodontics, traditional methods such as brackets have undergone a change from the older ‘train-tracks’ of the past and can now be implemented smaller and are often clear in appearance, while treatment times have lessened, making the overall experience one that causes minimum interference to your life.For patients who are unhappy with their smile but unwilling to face the pain and discomfort of fixed metal braces, a revolutionary system called Clearstep could be just the solution they have been looking for. Clearstep is an affordable and effective way of straightening teeth that comes with the huge advantage of being almost completely invisible.Invisalign is the other method of straightening misaligned teeth in both children and adults

For adults requiring braces, whatever your orthodontic needs, there exists an option to help achieve the straight smile you’ve always wanted  to project yourself with the confidence you need in both your personal and professional life.Orthodontics braces have ability to enhance the size and shape of your smile, allowing you to shine through and leave behind your insecurities.

Cadent iTero : Digital Impression System

Posted in Dental News by UK Dental Tourism on February 20, 2010

The Cadent iTero is a digital imaging system that eliminates the need for impressions for fixed prosthetics. The penetration in dentistry of these types of devices is pretty low currently, but we can foresee big things for the iTero.

The Cadent iTero digital impression system takes a highly accurate virtual 3d impression of patients’ crown or bridge area, ensuring an accurate model quickly, eliminating the uncomfortable tray and putty impression.It features parallel confocal imaging,which uses laser and opticl scanning to digitally capture the surface and contours of toothand gingival surfaces.The iTero software guides users through every step of scanning process.The time to complete the scanning sequence routinely requires just 3 to 5 minutes.And with no time devoted to preparing impression trays or clean up, the time saving is predictable.Most importantly the unmatched precision of iTero crowns requires minimal adjustment. Infact 90% of their restorations are being seated with no adjustments.That is a huge advantage over traditional methodologies. If that proves to be the case, we will begin to shrink our impression material inventory.

Patient acceptance? Outstanding. Not having to suffer through impressions is a big plus for patients.With iTero patients become engaged in the process as they see their dental work on screen.Biggest of all ,the expenses and hassles associted with putty and trays will be a thing of the past as digital impressions eliminate the need for mixing materials.

Cosmetic Dentistry For A Perfect Smile

Cosmetic dentistry is a combination of conventional dentistry practices with an added emphasis on art and aesthetic qualities. Its primary aim is to make the teeth look more pleasant and appealing rather than specifically repairing any damage. It has become increasingly more popular in recent years thanks to the development of various dental techniques and the wider availability and affordability of treatments.

Advances in cosmetic dentistry have allowed dentists to reshape or remold your problem teeth. A dental procedure touted to change the appearance of a person’s problem tooth, teeth contouring is regarded as a quick and painless dental cosmetic treatment.

Teeth’s contouring is the solution to several dental problems, including:
• Cracked or chipped teeth
• Crooked teeth
• Overlapping teeth
• Teeth with holes or grooves
Not all individuals are suitable candidate for teeth contouring. Your dentist will determine if you are a suitable candidate by evaluating the health of your teeth and if your bone and tissue are strong enough to support a tooth contouring treatment.

The step by step teeth contouring process follows:
• X-ray examination to determine the strength of your tissue, bone and teeth.
• If you are a suitable candidate, your dentist will make a computer image to show how you will look after the teeth contouring process.
• Your teeth will be marked with a pen in preparation for the sculpting. Some of the materials that will be used are lasers, sanding drills and abrasive strips.
• Material bonding will be made to the tooth to fill cracks and chips, change the tooth’s colour and cover blemishes.
• The final step of the teeth contouring process is the polishing and smoothing.

With teeth contouring, it takes only two dental visits for you to have that smile that you have always dream of.Having a beautiful and healthy smile can make patients look much younger and is one of the most simple ways of making yourself more attractive. Make an appointment to discuss cosmetic dentistry with your dentist and see what wonders can be performed for your smile.

Useful Dental Tools : Dental Crowns

A dental crown is a ceramic cap that is cemented over an existing tooth to repair damage or to restore its cosmetic appearance. It is most commonly used to cap teeth that have been filled or to protect teeth broken as the result of a head trauma.

There are many ways a tooth can be damaged. Sporting injuries account for up to 50 per cent of dental injuries. Dentists advise wearing a mouth guard when playing any sport with a high level of physical contact or that can involve any kind of collision. However it is still common for teeth to be chipped, cracked or broken when playing sport. Teeth are also commonly damaged in motor vehicle accidents or from simply accidentally chewing on hard food. Damage to teeth will initially be repaired with composite dental bonding. This tooth coloured resin is used to fill cracks and repair chips but it can itself be susceptible to damage. Dentists therefore often use a dental crown to sit over the damaged tooth to protect it from further injury.

Dental crowns are also used to protect teeth that have had cavity fillings. This is especially true of teeth with large cavities as dental bonding, used as a filling material, is weaker in large areas. Crowns are also used to protect teeth that have been subject to a root canal procedure. This is when an infected tooth has been hollowed to remove the infection. A dental crown is the last step in a complex process designed to preserve the functionality of the patient’s original tooth and prevent extraction.

Dental crowns are commonly manufactured from porcelain, a type of ceramic with a similar consistency and appearance to tooth enamel. Modern crowns are increasingly fabricated using the latest computer-aided technology. Using 3D imaging and digital x-rays dentists can construct images of the patients’ teeth on a computer. They can then use this information to manufacture a dental crown by milling it from a single piece of porcelain in as little as six minutes. This new technology has reduced treatment time for patients and improved the accuracy of treatment.

Dental crowns are very versatile and useful dental tools that can prevent the need for further treatment. Patients with damaged teeth should make an appointment with a Dentist in Shimla to discuss the benefits of dental crowns.

Shimla Dentist Explains Dental Implants

Tags: , , ,

Despite advances in dental care and a greater awareness of dental problems such as tooth decay and gum disease, millions of people lose teeth each year due to decay or head trauma. In the past, patients wishing to replace a missing tooth had a choice between a partial denture or a dental bridge. These were, at best, only satisfactory substitutes for real teeth and always involved a significant adjustment of lifestyle for the patient. Certain foods became off limits because of the dangers of breaking parts of the prosthetic and patients were frequently worried about the embarrassment of dentures falling out at inopportune moments. All of that changed with the introduction of the dental implant.

Q. What exactly is a dental implant?

A. It is an artificial tooth designed to replace one tooth that has become damaged. A dental implant is a relatively new solution to missing teeth that involves drilling a small screw into the jawbone itself to act as an anchor for an artificial tooth. Because the implant is attached to the jawbone, it creates a similar feeling of stability to a real tooth, which is secured by a root..

Q. What advantages does an implant have against a natural one?

A. Some of the exceptional benefits Dental Implants provide include;

* Improved confidence and self-esteem
* Increased stability within the mouth
* Improved comfort and speech
* Increased preservation of bone
* Decreased gum tissue shrinkage
* Dietary and nutritional benefits
* Convenience – not always having to worry about Dentures
* An aesthetically enhanced smile

Q. Is it as expensive as plastic surgery?

A. When it comes to our teeth price shouldn’t be a problem, fortunately dental implants aren’t too expensive like plastic surgery, which often needs to re-done every few years.In the initial many patients feel that dental implant treatment is expensive compared to other dental procedures. However, Dental Implants represent a more permanent and natural solution than other dentistry treatments, for instance complete Dentures or Partials.

Q. Is it painful, during the procedure and afterwards?

A. Not especially so, pain management methods these days are quite incredible. All most patients suffer is a little discomfort for a few days while the mouth heals, and they adjust to the new tooth.Statistics show that while you may be conscious for the dental procedure, there is virtually no pain, discomfort, and more importantly there is no fear while you undertake Sedation Dentistry.

Q. What is the procedure exactly?

A. Dental implants are usually completed in two phases:
Phase 1 Surgical
During the first stage of treatment, the actual implant is placed. This process is generally performed in our office with light sedation to help make the patient more comfortable. Using precise, gentle surgical techniques, the Implant is placed into the jawbone for 3 to 6 months while osseointegration (bonding to bone) takes place. This helps ensure a strong, solid foundation for replacement teeth.

Phase 2 Restorative
In the second stage of treatment, we must create and attach the new tooth or teeth to the anchored Implant(s) in your jaw. Dental Implants can replace a single tooth, several teeth or complete denture.
