Implants

Dental Implants

Are you missing a permanent tooth?
Do you have gaps in your smile?
Do you wear dentures and experience some of the following problems:

  • Slipping and clicking while talking?
  • Irritation and pain when you chew?
  • Fear of eating in public?
  • Feeling or looking older than your age?

You may be a candidate for dental implants, an alternative to missing teeth. A dental implant uses your jawbone to hold a replacement tooth or bridge, rather than anchoring it to a healthy, neighboring tooth. The results are natural-looking teeth that look, feel, and function as your own! Healthy teeth are a gift we often take for granted. Losing one or more teeth impacts our smile, our confidence, and our enjoyment of our favorite foods. Dental implants are technology's way of taking us a step closer to replacement teeth that feel secure and look like our own.

What Is Involved in Getting Implants?

The implant process takes several steps, but you will be able to continue your regular professional and social routines. Initially, the dentist will evaluate your mouth, teeth, and jaw to determine whether implants are a good option for you. For most patients, there are two surgical procedures involved. First, in the actual implant placement, the implants are surgically inserted into or atop the jawbone. Over the next three to six months, the implants are left alone, so that the anchor can bond to the bone, creating a strong foundation for the teeth that will be attached to them. Second, the new tooth or teeth are created and attached to the anchored implant. You now have teeth that might as well be nature's own: they look natural, are comfortable, and withstand the rigors of grinding and chewing. No one will know that your tooth has an artificial, man-made tooth root.

Implants Are Not for Everyone

It's true. Your current dental health will influence whether you're a good candidate. Some medical conditions may interfere with normal healing, such as diabetes or heart problems. Finally, the supporting bone in your jaw must be healthy; if you clench your jaw or grind your teeth, the success rate for your implants will drop. Less success also is noted in smokers. A complete examination and X-rays by your dentist will determine if you are a suitable candidate for dental implants. You must also commit to a strict schedule of flossing, brushing, rinsing, and check-ups to keep them healthy. Today, there are patients who have had implants for more than 25 years. Hundreds of thousands of dental implants have now been inserted, boasting more than a 90% success rate! Metal joint implants used in other parts of the body were actually developed from the success of dental implants. It has been around for decades and people know it works. Schedule an evaluation with your dentist to determine if dental implants are right for you. Discover how they can improve your quality of life and put a genuine smile on your face.

Crowns

How Long Do Crowns Last?

This is one of the most difficult questions asked of a dentist because, in essence, no one can be sure. However, there are a few resources available that can give us an idea of how long crowns may last. One resource is insurance companies. Even though the insurance company should not dictate the type of treatment that should be done, they give some insight into the matter. Insurance companies will pay for a new crown on the same tooth after five years. So, in essence, they believe that a crown will last at least five years. Another resource available is the dental literature. The dental research has some extreme variability in this area. It provides information that ranges from a 20% failure rate in 3 years all the way to a 3% failure rate in 23 years. So, which is correct? The answer actually has to be looked at on a case-by-case basis. To do this, we need to look at why crowns have to be replaced.

Why Do Crowns Need to Be Redone?

There are many reasons why crowns need to be redone.

Fracture is one example. The fracture incidence of crowns can be related to either the type of restoration (gold, metal ceramic, all-ceramic) or where the restoration is placed in the mouth (anterior vs. posterior). Another risk factor is if a person has a grinding habit at night. A crown will have a higher risk of fracture in a mouth that applies more forces to the teeth by grinding than in one that does not have any incidence of grinding.

Decay can be another reason why a crown needs to be replaced. Just because a tooth receives a crown does not mean it is less prone to decay. In fact, because it has more areas that may trap plaque, it needs to be cleaned as well, if not more meticulously, during home care.

Aesthetics can be another reason why crowns are replaced. Esthetics is one of the main reasons people choose to have a new crown made in the anterior part of the mouth. This occurs because as we get older, our teeth will change color and progressively get darker while the tooth with the crown will stay the same color as the day it was placed. A discrepancy between the color of the teeth will become more evident over time. In addition to color, esthetic changes in the position of the gum tissue over time can also affect the look of the crown.

Which one of these areas may be a factor in a patient's mouth is uncertain. An idea can be obtained by evaluating the reason a crown was needed in the first place (such as a fractured tooth, decay, etc.). In conclusion, it is unclear how long a crown will last. Their life span may be anywhere from a few years all the way to 20 years and beyond.

Snoring/Sleep Apnea

The Adjustable PM Positioner

The adjustable PM is a mandibular repositioning appliance designed for use treating snoring and sleep apnea, with bases of a thermo-active acrylic material fitting over the upper and lower teeth. Expansion screws on the left and right cheek areas control the anterior-posterior positioning of the lower jaw to achieve optimal effectiveness with comfort. Some lateral movement is possible and the tongue space is unobstructed.

Strips, sprays and special pillows are usually ineffective and a waste of money. Contact Dr. Robert Loy today for a better and quieter nights sleep.

Temporomandibular Joint Disorder


(TMJD, TMJ or TMD) or TMJ Syndrome is an umbrella term covering acute or chronic inflammation of the temporomandibular joint that connects the lower jaw to the skull. The disorder and resultant dysfunction can result in significant pain and impairment. Because the disorder has many facets the boundaries between several health-care disciplines — in particular, dentistry, neurology, and physical therapy offer a variety of quite different treatment approaches.

The temporomandibular joint is susceptible to many of the conditions that affect other joints in the body, including ankylosis, arthritis, trauma, dislocations.
 

Signs and Symptoms

Signs and symptoms of temporomandibular joint disorder vary in their presentation and can be very complex. Often the symptoms will involve more than one of the numerous TMJ components: muscles, nerves, tendons, ligaments, bones and the teeth. Ear pain is a common symptom of temporomandibular joint disorder.

Muscles

Disorders of the muscles of the temporomandibular joint are the most common complaints by TMD patients. The two major observations concerning the muscles are pain and dysfunction. The dysfunction can present as a limitation of jaw movement ranging from minor to severe. In milder cases, the only representation may be joint sounds such as clicking or popping. These symptoms of TMD are often caused by over usage of the muscles. Common causes include chewing gum continuously, biting habits (fingernails and pencils), grinding habits, and clenching habits.

Muscle pain can sometimes be associated with trigger points in muscle tissue. These trigger points can be localized by digital palpation, both intra-orally and extra-orally. This is known as Myofascial pain syndrome.

Any dysfunction of the muscles may cause the teeth to bite with each other incorrectly. If teeth are traumatized by this they may become sensitive, demonstrating one of the many interplays between muscle, joint, and tooth.

Temporomandibular Joints

This is arguably the most complex set of joints in the human body. Unlike typical finger or vertebral junctions, each TMJ actually has two joints, which allow it to both rotate and to slide. With use, it is common to see wear of both the bone and cartilage components of it. Clicking is common, as are popping motions and deviations in the movements of the joint. It is considered a TMJ disorder when pain is involved.

In a healthy joint, the surfaces in contact with one another (bone and cartilage) do not have any receptors to transmit the feeling of pain. The pain therefore originates from one of the surrounding soft tissues. When the position from one of these areas is not aligned, the pain causes a reflex to limit the lower jaw's movement. Furthermore, inflammation of the joints can cause constant pain, even without movement of the jaw.
 

Due to close proximity of the ear to the temporomandibular joint, TMJ pain can often be confused with ear pain. Conversely, TMD is an important possible cause of secondary ear pain. Treatment of TMD may then significantly reduce symptoms of ear pain, as well as atypical facial pain.

The dysfunction involved is most often in regards to the relationship between the head of the lower jaw and the disc. The sounds produced by this misalignment are usually described as a "click" or a "pop" when a single sound is heard and as "crepitation" or "crepitus" when there are multiple, rough sounds.

Teeth

Disorders of the teeth can contribute to TMJ dysfunction. Tooth mobility and tooth loss can be caused by destruction of the supporting bone and by heavy forces being placed on teeth. Movement of the teeth affects how they contact one another when the mouth closes, and the overall relationship between the teeth, muscles, and joints can be altered.

Participating Factors

There are many external factors that place undue strain on the TMJ. These include but are not limited to the following:

Over-opening the jaw beyond its range for the individual or unusually aggressive or repetitive sliding of the jaw sideways or forward.  This may be due to:

  •     Modification of the occlusal surfaces of the teeth through dental neglect or accidental trauma.
  •     Excessive gum chewing or nail biting.
  •     Excessive jaw movements associated with exercise.
  •     Repetitive unconscious jaw movements associated with bruxing.

 

Treatment

Restoration of the occlusal surfaces of the teeth

If the biting surfaces of the teeth or the supporting structures have been damaged due to dental neglect, periodontal diseases or trauma, the proper biting surface should be restored.

Pain Relief

While conventional analgesic pain killers such as NSAID's (Ibuprophen) provide initial relief for some sufferers, the pain is often from a number of possible causes, which may not respond well to these drugs.

Long-term approach

An approach to eliminating damaging habits involves the taking of a detailed history and careful physical examination. The medical history should be designed to reveal duration of illness and symptoms, previous treatment and effects, contributing medical findings, history of facial trauma, and a search for habits that may have produced or enhanced symptoms. Particular attention should be directed in identifying jaw habits, such as clenching or teeth grinding, lip or cheek biting, or positioning of the lower jaw in an edge-to-edge bite. All of the above strain the muscles of and results in jaw pain.

Treatment is oriented to eliminating oral habits, physical therapy to the muscles, and alleviating bad posture of the head and neck. A flat-plane full-coverage oral appliance, e.g. a stabilization splint, often is helpful to control bruxism (grinding) and take stress off the temporomandibular joint.

According to the National Institute of Dental and Craniofacial Research (NIDCR) of the National Institutes of Health (NIH), TMJ treatments should be reversible whenever possible. That means that the treatment should not cause permanent changes to the jaw or teeth. Examples of reversible treatments are:

  • Stabilization splint is the most widely used treatment for TMJ and jaw muscle problems. If an oral splint is recommended, it should not cause permanent changes in the bite.  Avoid using over-the-counter mouth guards for TMJ treatment. If a splint is not properly fitted, the teeth may shift and worsen the condition.
  • A typical long-term permanent treatment (if the device is proven to work especially well for the situation) would be to convert the device to a flat-plane bite plate covering the upper teeth and to be used only at night.
  • Over-the-counter pain medications, used according to manufacturers’ instructions.
  • Prescription medications prescribed by a healthcare provider.
  • Gentle jaw stretching and relaxation exercises you can do at home. Your healthcare provider can recommend exercises for your particular condition, if appropriate.

What may be concluded is that there are various treatment modalities that a well-trained experienced dentist may employ to relieve symptoms and improve joint function. They include:

  • Manual adjustment of the bite by grinding the teeth
  • Splints that move the jaw, ligaments and muscles into a new position.
  • Reconstructive dentistry
  • Orthodontics

Exercise protocols, habit control, and splinting should be the first line of approach, leaving oral surgery as a last resort. Certainly a focus on other possible causes of facial pain and jaw immobility and dysfunction should be the initial consideration of the examining oral-facial pain specialist.
