Abstract: An interocclusal appliance is formed from a single polymer material composition as one unitary piece or from multiple polymer material compositions as a two-piece preform. The two-piece preform includes a base material and an impression material that has a softening point lower than the base material. Teeth are received into the heat-softened impression material, so as to contour the impression material. A portion of the impression material also may contour to a portion of the user's palate. In certain embodiments, substantially no polymeric material contacts the front surfaces of the front teeth, leading to greater comfort and better air flow between front teeth. In still another embodiment, the appliance fits over front teeth only and no polymeric material contacts the maxillary molars.

Abstract: An intra-oral device used for people that snore or have sleep apnea is designed to move a user's lower jaw forward relative to the user's immovable upper jaw and to prevent the user's mouth from inadvertently opening while sleeping. The device includes upper and lower appliances fitted to the user's respective upper and lower dental arches. The lower appliance possesses a partially embedded bracket. An adjustment element is integrated into the upper portion of the bracket. With the user's mouth closed and the upper and lower appliances positioned over the user's respective dental arches, the adjustment element is moved rearward by worm action into load bearing contact against the forward facing immovable vertical contact wall of the upper appliance. This action moves the lower appliance forward, and thus, the user's lower jaw with its anatomically attached tongue are also moved forward relative to the mouth which in turn opens the user's airway.

The inserts possess different physical properties than the carrier and may be positioned and shaped to mechanically buffer teeth of the arch from mechanical shocks as well as release beneficial agents. The inserts may be replaced or refreshed to maintain the beneficial agent. A dental device having a core carrying a beneficial agent inside a liquid-permeable shell functions as an infant's teething device.

Abstract: The invention is an oral appliance for prevention of sleeping problems including snoring, sleep apnea and bruxism.

Abstract: A device and method for relieving head, neck, facial, joint and tooth pain. An intra-oral, semi-custom, separating device, worn over the upper anterior teeth, allows at least one lower anterior tooth to contact the rear wall of the device within the user's freeway space and prevents lower posterior teeth from contacting upper posterior teeth. The device provides a method of deprogramming and releasing the muscles of the upper and lower jaws. The device comprises an extruded or molded shell made of a hard polycarbonate or similar hard plastic material. The internal surface of the shell is lined with a moldable thermoplastic resin with a low molding temperature which allows the user to mold the internal aspect of the device onto and over the teeth to produce a custom fitted device. This relieves the stresses, strains, pains and damage that can be caused by parafunctioning of the dental neural-muscular system.

The first internal layer is a nonsoftenable flexible framework which will permit the mouthguard to hold its shape during fitting as well as to absorb and dissipate significant impact conveyed to the upper teeth. A hard, durable bite plate wedge lowers the condyle from the temporomandibular joint in a fulcrum action to place the lower jaw in an optimum condition preventing impingement upon the nerves and arteries as well as spacing the upper and lower teeth apart. Elastomeric traction pads are on the bottom of the mouthguard and are grippingly engaged by the posterior teeth of the lower jaw.

Abstract: An appliance, a system and a method correct habits of an oral cavity of a patient. The appliance is preformed or is custom-made in an open position or in a closed position. The appliance prevents the patient from breathing through an oral cavity of the patient and encourages the patient to breathe through a nose of the patient. The appliance corrects abnormal swallowing patterns, finger sucking habits, thumb sucking habits, abnormal tongue posturing, abnormal lip posturing and/or speech problems. A slot is formed on a top portion of the appliance to receive teeth of the patient for wearing the appliance. A shelf is formed on a bottom portion of the appliance to move a tongue of the patient to a correct position within the oral cavity during swallowing movements and/or during resting periods between the swallowing movements since there is more room above the shelf from a hollow area above of the shelf which is more comfortable for the patient.

Abstract: A semi-custom intraoral discluder device for preventing chronic tension and common migraine headaches and temporomandibular disorders that are caused or perpetuated by chronic activity of the temporalis muscle. The discluder includes a trough, contoured to encompass at least one maxillary or mandibular incisor, from which extends a protrusion, typically of a dome shape. The trough can be retained on the teeth by any adaptable material which can flow around the teeth and then maintain its shape. The adaptation of the retentive material can be performed by the end user, health care provider, or anyone trained in the art. Once in place in the wearer's mouth, one or two opposing incisor teeth will come into contact with the protrusion prior to the upper and lower posterior and/or canine teeth coming into contact, regardless of the position of the mandible, thereby reducing the intensity of the activity of the temporalis muscle.
