Process for programming an orthodontic component from a shape memory material starting from an initial shape of the orthodontic component into a target shape to be programmed of the orthodontic component, wherein the target shape compared to the initial shape at least sectionally has a severe bending, the process comprising the following steps:

Process to program an orthodontic component from a shape memory material

A process to manufacture a patient-specific replacement bracket includes providing a 3D representation of the supramaxilla or submaxilla of a patient in the target set-up with a reference plane in a computer. A request to manufacture a replacement bracket is received. A sector of the 3D representation is defined and contains at least a section of the tooth for which the replacement bracket is to be manufactured. A marking is generated for the slot plane in the sector. A physical model of the sector with the marking is created. A bracket element containing the slot is provided. The bracket element is aligned to the slot plane. An individualized pad is assigned to the bracket element, whereby the replacement bracket is manufactured.

Method for producing a patient-specific replacement bracket for an orthodontic treatment, and bracket produced by this method

A customized orthodontic bracket system is provided. The system can include a bracket having a customized bracket bonding pad for bonding the bracket to a tooth of a patient and a bracket slot adapted to receive a customized archwire. The customized archwire is adapted to be positioned in the bracket slot to form a precise bracket slot-archwire interface. The bracket slot and the archwire when positioned in the bracket slot can be positioned substantially adjacent the tooth surface to reduce induced vertical error in tooth positioning. The bracket slot can be configured to have a bracket slot width substantially matching a cross-section of the archwire to reduce torque rotation around an axis of the archwire when positioned therein to further enhance end-of-treatment tooth positioning and reduce overall treatment time.

Customized orthodontic bracket system

A method for producing a patient-specific modular bracket having a pad and a bracket body. A bracket body library of bracket bodies includes bodies that are formed from a raw bracket body having a spacer section. A first parameter is established for cutting through the spacer section from a slot of the bracket body to set a height of the bracket body. A second parameter is established for cutting through the spacer section at an angle to a mesio-distal axis of the bracket body to set a torque value of the bracket body. A third parameter is established for cutting through the spacer section at an angle to an occlusal-gingival axis to set a rotation value of the bracket body. The spacer section is cut through according to the first, second and third parameters. Patient specific set-ups are then created by selecting and attaching pads from a raw pad library.

Method for producing at least one patient-specific modularly composed bracket body and corresponding bracket

A method for producing at least one patient-specific pad for a modular bracket having a pad and a bracket body includes providing a pad material section. A punch is provided having at least one punching stamp for punching out at least one raw pad from the pad material section. At least one pad is punched out from the pad material section with the punch to produce a raw pad library. A patient-specific set-up is generated. The set-up is made of plaster, and includes the teeth to be treated of an upper jaw and/or of a lower jaw of a patient. A raw pad is selected from the raw pad library for a patient's tooth to be treated. A gap between the raw pad and the corresponding tooth in the set-up is filled using a filling material to produce for the pad a tooth-specific glued surface allowing for a form-fit to the clinical tooth of the patient.

Method for producing a patient-specific pad and corresponding pad

Method for producing a patient-specific bracket body () for a modular bracket () having a pad () and a bracket body (), which comprises the following steps:

Method for producing a patient-specific bracket body and corresponding bracket body

Methods of use are provided, relating to a bracket with a pad for affixing it to a tooth of a patient, with a bracket body that has a slot for receiving an orthodontic wire, and with a channel-like wire guide which has wire guide surfaces for guiding the wire and which is assigned a lateral insertion area for insertion of the wire into the wire guide, wherein the insertion area has, in the longitudinal direction of the wire, a curved section through which the wire can be inserted into the wire guide in an elastically deformed state, such that the wire, on forming back to a rectilinear state, locks in the wire guide, and that the wire guide surfaces enclose the wire in a circle shape, such that the wire is held longitudinally displaceably in the wire guide by the wire guide surfaces and is secured against escaping laterally from the wire guide.

Orthodontic bracket with a pad

A bite corrector for moving the relative positions of the jaws includes a telescoping assembly with an outer member and an inner member received in the outer member. The outer and inner members have matching, curved configurations. Both of the members remain in close proximity to the patient's dentition during opening and closing movement of the jaws and the likelihood of contact of the bite corrector with adjacent tissue in the patient's oral cavity is reduced.

Low profile orthodontic bite corrector

Bracket () with a pad () for affixing it to a tooth of a patient, with a bracket body () that has a slot () for receiving an orthodontic wire (), and with a channel-like wire guide () which has wire guide surfaces (F) for guiding the wire () and which is assigned a lateral insertion area () for insertion of the wire () into the wire guide (), wherein the insertion area () has, in the longitudinal direction of the wire (), a curved section (A) through which the wire () can be inserted into the wire guide () in an elastically deformed state, such that the wire (), on forming back to a rectilinear state, locks in the wire guide (), and that the wire guide surfaces (F) enclose the wire () in a circle shape, such that the wire () is held longitudinally displaceably in the wire guide () by the wire guide surfaces (F) and is secured against escaping laterally from the wire guide ().

A customized orthodontic bracket system is provided. The system can include a bracket having a customized bracket bonding pad for bonding the bracket to a tooth of a patient and a bracket slot adapted to receive a customized archwire. The customized archwire is adapted to be positioned in the bracket slot to form a precise bracket slot-archwire interface. The bracket slot and the archwire when positioned in the bracket slot can be positioned substantially adjacent the tooth surface to reduce induced vertical error when the tooth is in a finished position and substantially parallel to the directly adjacent portion of the tooth surface to reduce bracket thickness. The bracket slot can also be configured to have a bracket slot width substantially matching a dimension of a cross-section of the archwire to reduce torque rotation around an axis of the archwire when positioned therein to further enhance end-of-treatment tooth positioning and reduce overall treatment time.

A set of customized orthodontic brackets are provided with slots that are arranged substantially parallel to the tooth surface. The archwire, in an as-manufactured condition, has a portion of substantial arcuate extent, which is canted relative to the occlusal plane. The brackets are designed on a computer as a combination of three-dimensional virtual objects comprising the virtual bracket bonding pad and a separate virtual bracket body retrieved from a library of virtual bracket bodies. The virtual brackets can be represented as a file containing digital shape data and exported to a rapid prototype fabrication device for fabrication of the bracket in wax or other material and casting the wax prototype in a suitable alloy. Other manufacturing techniques are also contemplated, including milling and laser sintering.
