WhytheTreatmentModelforYourJawJointDisorderMatters

Your temporomandibular joints (TMJ), located where your lower jaw meets the skull, play an essential role in nearly every mouth function. It’s nearly impossible to eat or speak without them.

Likewise, jaw joint disorders (temporomandibular joint disorders or TMD) can make your life miserable. Not only can you experience extreme discomfort or pain, your ability to eat certain foods or speak clearly could be impaired.

But don’t assume you have TMD if you have these and other symptoms — there are other conditions with similar symptoms. You’ll need a definitive diagnosis of TMD from a qualified physician or dentist, particularly one who’s completed post-graduate programs in Oral Medicine or Orofacial Pain, before considering treatment.

If you are diagnosed with TMD, you may then face treatment choices that emanate from one of two models: one is an older dental model based on theories that the joint and muscle dysfunction is mainly caused by poor bites or other dental problems. This model encourages treatments like orthodontically moving teeth, crowning problem teeth or adjusting bites by grinding down tooth surfaces.

A newer treatment model, though, has supplanted this older one and is now practiced by the majority of dentists. This is a medical model that views TMJs like any other joint in the body, and thus subject to the same sort of orthopedic problems found elsewhere: sore muscles, inflamed joints, strained tendons and ligaments, and disk problems. Treatments tend to be less invasive or irreversible than those from the dental model.

The newer model encourages treatments like physical therapy, medication, occlusive guards or stress management. The American Association of Dental Research (AADR) in fact recommends that TMD patients begin their treatment from the medical model rather than the dental one, unless there are indications to the contrary. Many studies have concluded that a majority of patients gain significant relief with these types of therapies.

If a physician or dentist recommends more invasive treatment, particularly surgery, consider seeking a second opinion. Unlike the therapies mentioned above, surgical treatments have a spotty record when it comes to effectiveness — some patients even report their conditions worsening afterward. Try the less-invasive approach first — you may find improvement in your symptoms and quality of life.

WaitingtoAffordImplantsConsideraFlexibleRPDintheMeantime

If you’ve lost some teeth you may eventually want to replace them with dental implants. Implants by far are the restoration of choice due to their life-likeness and durability. But those advantages don’t come cheaply — implants can be expensive especially for multiple teeth.

If you’re forced to wait financially for implants, you still have other intermediary options like a removable partial denture (RPD). The conventional RPD has a rigid acrylic base colored to resemble gum tissue supported by a metal frame with attached prosthetic (false) teeth at the missing teeth locations. They’re held secure in the mouth through metal clasps that fit over the remaining teeth.

But these conventional RPDs can sometimes be uncomfortable to wear and don’t always cover the bottom of the gum completely. If this is a concern, you might consider an alternative: flexible RPDs. The base of this RPD is made of a form of flexible nylon rather than acrylic plastic. They’re much more lightweight but still fit securely in the mouth with thin plastic extensions rather than metal clasps. The base can also be more easily formed to cover areas where gum tissue may have receded.

While flexible RPDs hold up better to wear and tear than their conventional counterparts, they must still be maintained like any other appliance. They can accumulate plaque (bacterial biofilm) responsible for tooth decay and periodontal (gum) disease, so daily thorough cleaning is a must. And if there fit becomes loose they can be more difficult to reline or repair than other types of dentures.

They also share a common weakness with other dentures — they can’t prevent and may even stimulate bone loss. As bone ages, old cells dissolve and new ones form to take their place. As we eat and chew our teeth transmit the forces generated through the teeth to the bone to stimulate it to grow. RPDs and other dentures can’t transmit this stimulus, so the bone replaces much slower to the point that the bone volume can diminish.

That’s why it’s best to consider any RPD as a temporary solution until you can obtain an implant for a more permanent and bone-friendly option. In the meantime, though, an RPD can provide you with a great solution for both form and function for missing teeth.
