WHAT ARE DENTAL IMPLANTS?

What Are Dental Implants?

Dental implants are replacement tooth roots. Implants provide a strong foundation for fixed (permanent) or removable replacement teeth that are made to match your natural teeth.
What Are the Advantages of Dental Implants?
There are many advantages to dental implants, including:
Improved appearance. Dental implants look and feel like your own teeth. And because they are designed to fuse with bone, they become permanent.
Improved speech. With poor-fitting dentures, the teeth can slip within the mouth causing you to mumble or slur your words. Dental implants allow you to speak without the worry that your teeth might slip.
Improved comfort. Because they become part of you, implants eliminate the discomfort of removable dentures.
Easier eating. Sliding dentures can make chewing difficult. Dental implants function like your own teeth, allowing you to eat your favorite foods with confidence and without pain.
Improved self-esteem. Dental implants can give you back your smile, and help you feel better about yourself.
Improved oral health. Dental implants don't require reducing other teeth, as a tooth-supported bridge does. Because nearby teeth are not altered to support the implant, more of your own teeth are left intact, improving your long-term oral health. Individual implants also allow easier access between teeth, improving oral hygiene.
Durability. Implants are very durable and will last many years. With good care, many implants last a lifetime.
Convenience. Removable dentures are just that; removable. Dental implants eliminate the embarrassing inconvenience of removing your dentures, as well as the need for messy adhesives to keep your dentures in place.
Can Anyone Get Dental Implants?
In most cases, anyone healthy enough to undergo a routine dental extraction or oral surgery can be considered for an implant procedure. Patients should have healthy gums and enough bone to hold the implant. They also must be committed to good oral hygiene and regular dental visits.

PARTIAL DENTURES

Partial Dentures

It is very important to replace missing teeth for several reasons;
 Appearance.
 Mastication or chewing ability.
 Support of remaining teeth.
 Support of an opposing full denture.
Without complete dentition, you may not be able to adequately masticate your food. Mastication, as opposed to biting and swallowing, involves mixing enough saliva with your food so that you adequately dilute your gastric juices, thereby reducing the risk of digestive problems. Remember when mum told us as kids that we had to chew our food slowly so that we didn’t get a sore tummy?
A partial denture, as the name suggests, is to replace some missing teeth in either or both the upper or lower arch. Sometimes a partial denture is required in one arch simply for appearance. More often it is required to improve mastication ability, but if remaining teeth are left unsupported, they may also drift sideways or over erupt making future replacement considerably more difficult.
The other major reason to wear a partial denture is to support an opposing full denture. As an example, where you have a full upper denture and only six remaining lower front teeth – a very common scenario – when you bite on the front teeth of the denture, you will tilt the back of the denture down. Also it is impossible to satisfactorily masticate food without full dentition.

Valplast® dentures are made from an injected thermoplastic nylon.
They are flexible, translucent, clinically unbreakable and require no metal retainers because the flexibility of the base is used to retain the denture. Another retention option for Valplast® Flexible Partial dentures is clear or tooth coloured resin retainers. Repairs, reline or addition of future lost teeth may be possible, but the process often means you will be required to be without your denture for about a week. Ask your DP for more information if this may be a concern to you.

Lucitone® FRS™ is strong, adjustable and flexible. It is an injected thermoplastic nylon ,but is more rigid and therefore available for use in more situations than Valplast®. Another retention option for Lucitone® FRS™ dentures is clear or tooth coloured retainers. Repairs, reline or addition
of future lost teeth may be possible, but it is important to check with your DP.

Benefits include:
 Easy to adjust, grind and polish
 Injected with Success® for proven accuracy.
 Easy chairside adjustment
 Monomer and metal free
 Clear clasps; no more matching tooth shades
 Better impact and stain resistance vs. Valplast®

Malocclusion and Orthodontics

Malocclusion and Orthodontics

What is malocclusion?
Malocclusion means having crooked teeth or a "poor bite."
Orthodontic treatment can correct the way teeth and jaws line up. Dentists who are specially trained to correct malocclusion are called orthodontists. They use a variety of treatment tools and techniques (including braces to move teeth, and sometimes the jaw, into the right places.
What causes malocclusion?
A common cause of malocclusion is teeth that have too much or too little room in the jaw. If children have a small jaw, their teeth may grow into a space that is too small. As a result, teeth may grow or drift out of place.
Other causes of crooked teeth include thumb-sucking, pacifier use, and tooth loss.
What are the symptoms?
The most obvious sign is teeth that are crooked or stick out. Malocclusion can range from mild to severe. Most of the time, having crooked teeth is only a cosmetic problem, meaning people don't like the way their teeth look. But in severe cases, it can cause problems with eating or speaking.
How is malocclusion diagnosed?
A dentist usually checks for malocclusion in children during regular dental visits. If the jaw or teeth are out of line, the dentist may suggest a visit to an orthodontist. The American Association of Orthodontists recommends that all children get a checkup with an orthodontist by age 7.
An orthodontist will:

• Ask questions about your or your child's past health problems.
• Check the mouth and teeth.
• Take X-rays of the face and teeth.
• Take photographs of the face and teeth.
• Make a plaster model of the teeth.

Start your child’s trips to the dentist at age 12 months. This will help your child get used to seeing a dentist. It will also catch any early problems. Keep up with regular dental checkups 2 times a year.

AMELOGENESIS IMPERFECT

AMELOGENESIS IMPERFECT

Amelogenesis imperfect presents with abnormal formation of the enamel or external layer of teeth. Enamel is composed mostly of mineral, that is formed and regulated by the proteins in it. Amelogenesis imperfecta is due to the malfunction of the proteins in the enamel: ameloblastin, enamelin, tuftelin and amelogenin.
People afflicted with amelogenesis imperfect have teeth with abnormal color: yellow, brown or grey. The teeth have a higher risk for dental cavities and are hypersensitive to temperature changes. This disorder can afflict any number of teeth.
Genetics
Amelogenesis imperfecta can have different inheritance patterns depending on the gene that is altered. Most cases are caused by mutations in the ENAM gene and are inherited in an autosomal dominant pattern. This type of inheritance means one copy of the altered gene in each cell is sufficient to cause the disorder.
Amelogenesis imperfect is also inherited in an autosomal recessive pattern; this form of the disorder can result from mutations in the ENAM or MMP20 gene. Autosomal recessive inheritance means two copies of the gene in each cell are altered.
About 5% of amelogenesis imperfecta cases are caused by mutations in the AMELX gene and are inherited in an X-linked pattern. A condition is considered X-linked if the mutated gene that causes the disorder is located on the X chromosome, one of the two sex chromosomes. In most cases, males with an X-linked form of this condition experience more severe dental abnormalities than affected females.
Other cases of this condition result from new gene mutations and occur in people with no history of the disorder in their family.
Treatment
Crowns are sometimes being used to compensate for the soft enamel. Usually stainless steel crowns are used in children which may be replaced by porcelain once they reach adulthood. In the worst case scenario, the teeth may have to be extracted and implants or dentures are required.

DENTAL ABRASION

Dental Abrasion

It may seem logical that the harder you brush your teeth, the cleaner they'll be. But applying too much pressure can actually weaken the outer layers of the tooth structure. This condition, called dental abrasion, can occur when any foreign object causes friction against your teeth and gradually wears away the enamel on the surface. If you've noticed the signs of dental abrasion, small v-shaped notches near the gums, it may be time to review your oral hygiene regimen with your dentist or dental hygienist. Don't worry, you won't need to retire your toothbrush altogether.
Your dentist or dental hygienist can suggest proper techniques to restore and protect a healthy smile.
What Causes Abrasion?
Strenuous brushing is the most common culprit, but any object that repeatedly rubs against your teeth can wear them down. Using toothpicks improperly can contribute to dental abrasion, as well chewing on fingernails, pencils or other objects. In some cases, ill-fitting retainers or partial dentures can also be to blame. Believe it or not, the type of toothpaste you use may even be a factor as some formulas are more abrasive than others.
Consequences
While protecting the appearance of your teeth may be the most obvious reason to prevent and treat dental abrasion, weakened enamel can also contribute to more serious dental issues over time. Many patients experience increased tooth sensitive to heat and cold. In addition, without its protective outer layer, a tooth may be more susceptible to infection. In advanced cases, when dental abrasion is left undiagnosed and/or untreated, a tooth may need to be filled or even extracted.
