  • Patent number: 10004574
    Abstract: A method and apparatus with auto-inactivation for the lateral expansion or constriction of posterior teeth, anterior advancement or retraction of the anterior teeth, and distal expansion of the molars, bicuspids and canines is described. This system is for correction of the upper dental arch and jaw bone, nasal cavity constriction, or lower dental arch constriction, which helps to resolve the dental malposition, dental crowding, proper room for tongue position, and expansion of nasal cavity for improvement of airway. The appliance includes loaded springs around the wires connected to molar band with connector tubes and female attachments that are extended to the front tube. The spring creates a distalization force on the first and/or second molars, anterior extending force on front teeth including canines and incisors, and lateral expansion for the posterior teeth including, canines, bicuspids and molars.

  • Patent number: 9962240
    Abstract: The present invention relates to a dental implant fixture, and more particularly, to a dental implant fixture which rotates about a central axis thereof, and thus is inserted into a bone tissue constituted by a cortical bone and a spongy bone to form an artificial tooth root, wherein the dental implant fixture includes a first portion, a second portion, and a third portion. The first portion is inserted into the cortical bone and has an outer surface with a first screw thread whereon first vertices and first valleys are alternately arranged. The second portion is disposed beneath the first portion and inserted into the spongy bone, has an outer surface with a second screw thread whereon second vertices and second valleys are alternately arranged. The distance between the adjacent second vertices of the second screw thread is larger than the distance between the adjacent first vertices of the first screw thread.

  • Patent number: 9943384
    Abstract: A self-ligating orthodontic bracket includes a bracket body, a slide member, and a resilient member. The slide member is movable relative to the bracket body between an opened position, a first ligating position, and a second ligating position. In the first ligating position and in the second ligating position, a surface of the slide member bounds the archwire slot on a side generally opposite to the base surface to retain the archwire. The resilient member is configured to engage the other of the slide member and the bracket body and has a deformed state for biasing the slide member toward the base surface in at least one of the first and second ligating positions. In the first and second ligating positions, the base surface of the archwire slot and the surface of the slide member are separated by different distances.

  • Patent number: 9931182
    Abstract: An implant includes two internal anti-rotational features. One anti-rotational feature is adapted to engage a driving tool, while the other anti-rotational feature is adapted to engage an abutment. An implant abutment system is provided with an angled abutment adapted to mate with one of the anti-rotational features. A second, straight abutment is adapted to engage with the other anti-rotational feature. An abutment is provided with resilient fingers to interface with the implant and provide tactile and audible feedback indicating when the abutment is properly seated. An abutment screw extends through the abutment and engages the implant bore distal of the stem of the abutment. The abutment screw limits axial movement of the abutment relative to the implant. A driving tool includes one of at least retention structure and visual alignment indicia is provided to facilitate screwing the implant into a patient's bone.

  • Patent number: 9872749
    Abstract: The bite registration block is used for recording the relation between a patient's maxillary and mandibular arches for proper fabrication of a fixed dental prosthesis, or prostheses, such as fixed crowns or the like. The bite registration block is particularly adapted for use when a patient's prepared teeth are opposed by an edentulous arch (i.e., opposed by an area of missing teeth). The bite registration block is formed from a resilient material, such as a suitable type of plastic or the like, and is formed as a block having opposed upper and lower surfaces, a pair of laterally opposed side surfaces, and a pair of longitudinally opposed side surfaces. The upper surface defines a concave, longitudinally extending recess for positioning about an edentulous region of the patient's jaw.

  • Patent number: 9848960
    Abstract: An orthodontic appliance has a post attached to a first upper tooth, and a button with a recess attached to a second upper tooth. An elongated arm has an eye at one end through which the post is inserted to allow the elongated arm to rotate about the post, and a tip at the other end for removable insertion into the recess of the button. The length of the elongated arm is selectable to maintain a desired spacing between the first and second upper teeth (e.g., by cutting the tip of the elongated arm). An elastic extends from either the post or button to an attachment point on the patient's lower dental arch to exert a force between the patient's maxilla and mandible.
