The Benefits of Using a Comfort H/S Bite Splint

Grinding of the teeth is a medical condition called bruxism. Over time, bruxism will result in the wearing down of your natural tooth enamel. In fact, studies suggest that those who grind and clench their teeth may experience up to 80 times the normal wear per day compared to those who do not.

Dr. Gordon Christensen has estimated that one-third of the U.S. population either bruxes or clenches their teeth, which results in tooth damage. 1 The Comfort H/S Bite Splint can protect your teeth from this habit during sleep and periods of high stress.

Clinical Indications

Indicated for patients who show increased tooth wear or complain of pain resulting from bruxing or clenching.

Bruxism is when a patient clenches (tightly holds their top and bottom teeth together) or grinds (slides their teeth back and forth over each other) their teeth.

Signs and symptoms of bruxism may include:
  • Teeth grinding or clenching, grinding during the day and night.
  • Teeth that are flattened, fractured, chipped or loose
  • Worn tooth enamel, exposing deeper layers of a tooth
  • Increased tooth sensitivity
  • TMJ pain and soreness
  • Temporary headaches
  • Damage from chewing on the inside of cheek
  • Indentations on the tongue
In most cases, bruxism doesn't cause serious complications. But severe bruxism may lead to:
  • Damage to teeth, restorations, crowns or jaw
  • Tension-type headaches
  • Facial pain
  • Disorders that occur in the temporomandibular joints (TMJs), located just in front of the ears, which may sound like clicking when the patient opens and closes their mouth.

Preparation Requirements

  • Start with an accurate, void-free impression of both arches.
  • For a precise fit, ensure no tears or bubbles are present in impression material.
  • Instruct patient to close into centric relation, or intercuspation to verify midline position and bite.
  • Place two cotton rolls behind the cuspids and instruct the patient to close.
  • With the patient in this open centric relation, inject bite registration into the posterior openings of both quadrants.
  • Then inject bite registration into the anterior opening to capture a complete open construction bite at centric relation.
  • Protrusive bites can be provided to aid in proper condylar readings
  • Mounted casts should be properly indexed for appliance accuracy
