Abstract: Protrusions or holes with jagged edges formed on the lingual side of invisible aligner trays are provided. The protrusions or holes include two components and serve to irritate the tongue causing it to retract away from the incisors thus eliminating intruding force otherwise exerted by the tongue. A clear corrugated material is provided which is suited for making the aligner trays having the protrusions which otherwise would be difficult with standard thick material used. The lingual side protrusions are added by computer to the impressions taken from a patient's teeth such that the protrusions are formed on the dental model used to make the aligner trays.

Abstract: A lip advancer is presented for preventing proclining or tipping forward of the lower incisors that causes relapse and gingival recession in retention with forward intermaxillary elastic traction that extends diagonally from posterior bracket hooks in the lower arch anchored to hooks on upper anchorage appliances. In one embodiment, the lip advancer is comprised of an invisible clear liner type plastic retainer for use with a dental arch, and a bumper extending labially from the retainer for pressing against the patient's lip causing the lip muscles to react pushing back with an opposite force thus preventing the anterior teeth from flaring labially. In another embodiment, for use with a plurality of brackets and an archwire, the lip advancer comprises an auxiliary archwire extending from and in contact with the brackets, and a bumper formed on the auxiliary archwire for applying pressure labially to a corresponding lip.

Abstract: An orthodontic appliance for orthodontic treatment of a posterior maxillary sector extending from a mesial anchor tooth to a molar tooth unilaterally on the same side of the maxilla is provided. The appliance features a molar component, a mesial anchor tooth attachment, a long rod, and a hook. The long rod is saddle-shaped in the occlusal-gingival plane, and may have a distal step-down portion. The rod may extend at a mesial end thereof from the mesial anchor tooth attachment towards the molar component in a mesiodistal direction, and the rod may also have a mesial step-up portion starting from the mesial anchor tooth or premolar attachment. The hook may be located on the rod, for attachment with a traction element for direct molar traction. Under force of the traction element the rod exerts force on the molar component for molar distillation.

Abstract: An orthodontic molar distalizer having a molar component, a mesial anchor tooth attachment, and an elongate member therebetween. The elongate member features a hook for receiving a traction member for imparting distalizing force. A spring biasing means is positioned between the hook and the molar tube for applying distalizing force on the molar component and reducing canine over eruption. A telescopic distalizer comprised of an inner tube, an outer tube, and a plunger can be adjusted to a patient's anatomy. An arched distalizer having a threaded bolt connection between the elongate member and the molar component is also provided.

Abstract: An overbite correction device for use on an upper incisor or canine tooth is provided. The device has a bracket body including two rounded lingual protrusions, and a vertical slot therebetween; and a base for bonding to the upper incisor or canine tooth at a lingual side thereof by means of a bonding pad. The two curved lingual protrusions feature a curved lower-facing surface for receiving an incisor, to prevent incisor interference during grinding. The device may feature an aperture for receiving an elastic thread or metal ligature to tie multiple overbite correction devices together. Advantageously, if one device breaks off from a tooth, it is not ingested.

Abstract: A sliding molar distalizer is provided. The distalizer features a canine attachment bracket, a molar tube, and a rod connected to the bracket and having an engagement end for engaging the molar tube. A hook formed on a portion of the rod receives an elastic for imparting distalization force directly on the distalizer towards the molar tube. An orthodontic tube formed on the attachment bracket holds an archwire that passes through premolar brackets. A buccal push flange lever is formed at a distal portion of the rod for imparting force on the molar tube.
