Patent number: 7314372Abstract: A method and apparatus are provided for changing the form of the jaw and facial bones of an adult patient that did not develop fully during childhood. The method utilizes a device having a plate body with an expansion screw device that fits within the mouth of the patient, flap springs that project from the plate body and an overlay extending from the plate body. The device is placed within the mouth of the patient so that the overlay is in a position between at least two opposing teeth. In this position the flap springs press against selected teeth that are out of alignment in order to urge those teeth back into place. This force on the teeth causes the jawbone to expand to accept the teeth in their proper position(s). Also, the device is arranged such that the opposing teeth contact the overlay during swallowing, which causes the patient's facial muscles to intermittently pull on the facial bones.Type: GrantFiled: May 19, 2004Date of Patent: January 1, 2008Assignee: Orthovisage, Inc.Inventors: Theodore Belfor, Gurdev Dave Singh

Patent number: 6932598Abstract: The present invention is a device (18) and method for applying posteriorly directed pressure to a patient's upper posterior tooth, and anteriorly directed pressure to the lower teeth and lower jaw (50). The device includes a tooth attachment (22) fixed to a lower posterior tooth. A mounting base (20) is connected to the tooth attachment, and serves to mount a bumper unit (62), which extends from the lower posterior tooth to the upper posterior tooth.

Publication number: 20040170941Abstract: Traditional orthodontic treatment often involves the use of basic repositioning devices, such as braces, and the use of supplementary devices, components or accessories to achieve desired end results. Such components may be mounted on fixed, non-removable devices or they may be part of a removable appliance typically worn prior to the application of the fixed devices. As with traditional treatment, it may be desired to utilize similar components when repositioning teeth with removable elastic repositioning appliances. Due to the nature of elastic appliances, such components may take a variety of forms ranging from readily available traditional accessories to specially created devices. Thus, traditional components may be mounted on or embedded in an elastic appliance, or the appliance may be formed to provide similar components. Likewise, the appliance may be modified to provide additional features for specific orthodontic treatments.Type: ApplicationFiled: March 9, 2004Publication date: September 2, 2004Applicant: Align Technology, Inc.Inventors: Loc X.

Publication number: 20040096798Abstract: An orthodontic force module is made of an elastomeric material and includes one or more eyelet segments along with one or more connector segments coupled to the eyelet segments. The configuration of the eyelet segments and the connector segments is arranged so that a substantially constant cross-sectional area is provided throughout the working length of the force module. As a result, the resistance to elongation is substantially uniform throughout the working range of the force module and premature degradation and failure due to relatively high, concentrated stresses are avoided.Type: ApplicationFiled: November 19, 2002Publication date: May 20, 2004Applicant: 3M Innovative Properties CompanyInventor: James D.

Patent number: 6726475Abstract: A screw device for orthodontic treatment is formed with a platform part that has a relatively large radial width between a head part and a screw-body part of the screw device, and a neck part that has a radial width smaller than that of head part is also formed between the platform part and the head part. Therefore, a hook ring at the end of a spring (or rubber band) used for orthodontic treatment may be directly fitted from the head part and be positioned at the neck part without worrying about being dropped off. The thickness of the platform part may prop the spring up the gingiva for keeping from friction. By screwing the screw-body part into the maxilla (or mandible) to make the platform part abutted against the maxilla (or mandible), not only may a stable screwing force be provided for securing the screw, but also does the side surface of the platform have a function of facilitating the gingiva tissue to grow, so the healed-over wound will be more even and good looking.Type: GrantFiled: August 5, 2002Date of Patent: April 27, 2004Inventor: Cheng-Yi Lin

Patent number: 6719557Abstract: A contracting connector between a maxillary apparatus and mandibular apparatus to treat an underbite. The connector has a telescoping outer sheath connected at its posterior end to the maxillary apparatus. A rod is slidingly engaged in the sheath. And connected at its anterior end to the mandibular apparatus. A spring connected between the rod and the posterior end of the sheath exerts adjustable contraction pressure on the rod and thus the mandible. In another embodiment, the rod has separate anterior and posterior segments The posterior segment of the rod is attached to the maxillary apparatus and the anterior segment is attached to the mandibular apparatus A spring connected between the anterior and posterior segments exerts adjustable contracting pressure on the two rod segments and thus on the maxilla and the mandible. In either embodiment the contracting pressure on the spring is adjusted by changing the length of the telescoping outer sheath. An improved channel lock for connectors also is disclosed.Type: GrantFiled: October 12, 2001Date of Patent: April 13, 2004Inventor: Michael O. Williams

Publication number: 20040067464Abstract: An orthodontic pin includes a pin body and a fastening member screwed into the pin body. An elastic element is connected at an end to the orthodontic pin by extending the fastening member through a ring provided at the end of the elastic element before screwing it into the pin body. When the elastic element becomes loose due to any change in the position of a tooth being corrected, it can be determined the elastic element needs replacement. Since the fastening member can be easily loosened from the pin body of the orthodontic pin, the elastic element can be conveniently removed from the pin body to facilitate quick replacement of the elastic element.Type: ApplicationFiled: October 3, 2002Publication date: April 8, 2004Inventor: Fu Yi Lin
