What Is the Comfort H/S Hard Soft Bite Splint?

The Comfort H/S Hard Soft Bite Splint is designed to alleviate the pain and damage caused by bruxing or clenching of the teeth. It is the most widely prescribed bite splint available due to its comfort and fit, and is available in clear, blue, green and pink. Two layers make up the Comfort H/S Bite Splint: a 1 mm soft polyurethane inner layer that rests comfortably against the teeth and gums; and a 3 mm hard, clear copolyester outer layer that provides durability and bonds with acrylic for easy modification. Each splint is made with a standard flat occlusal plane and slight opposing cusp indentation or to your specific bite plane needs. The Comfort H/S Bite Splint is fabricated from ISO-certified ERKODENT® copolyester and polyurethane discs, which are BPA-free and non-allergenic.

How Does the Comfort H/S Bite Splint Work?

Severe tooth, jaw or facial muscle pain are common side effects of bruxing or clenching of the teeth. The good news is that these aches can be alleviated with a dentist-prescribed, custom-made Comfort H/S Bite Splint.

The Comfort H/S Bite Splint is a proactive step in protecting your existing healthy teeth. It is a clear, thin customized device that fits over your upper or lower teeth during sleep that can offset the effects of bruxing or clenching while protecting your teeth from daily wear and tear.

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.

The Comfort H/S Bite Splint provides many benefits. It is custom made and comfortable when worn in the mouth. In addition to relieving head, neck, jaw joint and shoulder pain, it protects existing teeth and dental restorations. It is highly recommended for those who have crowns, bridges, implants, veneers and dentures, to offset the effects of the often-subconscious habit of bruxing and clenching.

How Are Comfort H/S Bite Splints Made?

Comfort H/S Hard Soft Bite Splints are fabricated by thermoforming a dual-layer Erkoloc-pro 4 mm disc over a stone model using the Erkoform-3d state-of-the-art thermoforming unit with the Occluform-3® occlusal imprinting attachment. Erkoloc-pro copolyester/polyurethane discs are ISO approved for dental use and are BPA free. The Occluform-3 occlusal imprinting attachment allows a splint to be produced with either a flat occlusal plane and slight opposing cusp indentation, or anterior guidance with posterior disclusion using an open construction bite. After thermoforming, the splint is contoured using carbide burs, then polished with felt wheels and acrylic polish for a smooth and comfortable fit. Cold-cure acrylics can be used to increase vertical dimension by chemically bonding with the copolyester outer layer of the bite splint.

Indicated for patients who show increased tooth wear or complain of pain resulting from bruxing or clenching. The Comfort H/S Hard Soft Bite Splint is widely prescribed due to its comfort and fit.

Impression and Open Bite

Start with an accurate, void-free impression of both arches. For a precise fit, ensure that no tears or bubbles are present in the impression material. Instruct the patient to close into centric relation to verify the 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.


Seat the splint, and evaluate fit and retention. Once seated in the patient's mouth, check bite with marking tape to identify premature occlusion. If adjustments are necessary, adjust with a carbide bur or Lisko-S disc. Polish if needed.


Recommended Patient Cleaning Instructions

  • Brush and floss your teeth before placing the Comfort H/S Hard Soft Bite Splint in your mouth.
  • Do NOT soak the bite splint in mouthwash, denture cleaner or alcohol.

  • Clean the bite splint with soap and warm water ONLY.
  • If the bite splint becomes loose, tight or causes you any discomfort, contact your dentist immediately.
