Botox Treatment for Bruxism

Bruxism is one of the most wide spread Parafunction habits in the world.

A parafunctional habit is the routine exercise of a body part in a way that is other than the most common use of that body part. The term is most commonly used by dentists and orthodontists to refer to parafunctional uses of the mouth, tongue and jaw. Oral para-functional habits may include bruxism (tooth-clenching or grinding), tongue tension, mouth-breathing, and any other habitual use of the mouth unrelated to eating, drinking, or speaking.

Contrary to common belief, functional habits such as chewing are not the main cause of the wearing of teeth. Bruxism is the most destructive forces for several reasons. Teeth rarely come into contact during normal chewing and this activity is short lasting. Bruxism; the grinding of teeth may occur for 1 to 4 hours in a 24 hour period, most often this occurs during sleep. The amount of pressure placed on teeth during eating is 20–80 psi (0.14–0.55 MPa), but the pressure from clenching and grinding can range from 300 to 3000 psi (2.07 to 20.7 MPa). The direction of forces during eating are placed vertically along the long axis of teeth, which is the least harmful because of the anatomical structure of the attachment of teeth to the bone. On the other hand, grinding direct their forces horizontally, which is much more harmful.

Causes of Bruxism

There are three main cause of Bruxism, these include:

  • The interference and occusal precontacts for dental disuniformity.
  • The use of many neuropletic drugs, as all of these drugs are used by people who are prone to involuntary moments and stress! (which is currently the most accredited theory.
  • Stress - in predisposed persons stress and emotion tend to trigger Bruxism.

Treatment for Bruxism has not yet been precisely defined, and experts; dentists in particular are well aware that plaques, splints, bites as well as psychological stress reduction therapies are often ineffective and do not provide long lasting results.

How Botox Can Help

While it is a challenge to reduce the causes that promote this muscle activity, it is easy to reduce its frequency and potency with the use of Botox ( botulinum toxin A).

Over recent years, Botox has proven to be an extremely effective solution for the treatment of Bruxism. Botox when used correctly stems the clenching and grinding habit without any side effects.

The Botulinum toxin provides dentistry with an effective tool to control the extra capsular causes of TMJD (tempromandibular joint disorder) which reduces the excessive clenching and grinding process.

Pain is a large component and symptoms are exacerbated by external factors such as fatigue, stress, and emotional extremes. For those patients in pain, Botox is the first part of treatment plan, to establish normal muscle tonicity. This is then followed by issue of an occlusal splint, braces or other therapies to limit the muscles from reversing to their chronic painful state.

The commonly injected muscles are the masseter muscle and the temporalis muscles. Local injection of Botox type A in these muscles constitutes an innovative and adequately efficient treatment method for chronic facial pain associated with hyperactivity of the masticatory muscles. An improvement and alleviation of the painful symptoms can be expected in up to 90% of patients who do not respond to conservative treatment methods.
