A tooth moving device 1 according to the present invention comprises: a track part 6 extending from a mesial end 4 to a distal end 5 along a palate-side teeth alignment; a sliding part 7, slidably attached to the track part 6, and engaging with a holding member 51 attached to a maxillary posterior tooth; a lock part 8 fixed to the track part 6 close to the mesial end 4 relative to the sliding part 7; an elastic part 9 intervening between the lock part 8 and the sliding part 7 to bias the sliding part 7 toward the distal end; and anchoring part 2 and 3, anchored to an implanted member 53 implanted into a palate, and connected to the distal end 5.

In an embodiment, the present disclosure relates to a segmental distalization device that includes an elongate bar having a distal end and a mesial end, a distal base on the distal end of the elongate bar, a mesial base on the mesial end of the elongate bar, and an attachment member attached to at least one of the elongate bar, the distal base, and the mesial base. In some embodiments, the attachment member is operable to connect the segmental distalization device to an anchor via an elastic connector.

An orthodontic device having an anchor plate with holes for receiving screws to attach the anchor plate to the patient's maxilla or mandible, and a jaw displacer with a spring exerting an axial biasing force to reposition the mandible for malocclusion correction. A ball-and-socket connector is used to removably attach one end of the jaw displacer to the anchor plate. A second connector removably secures the second end of the jaw displacer to the other of the patient's mandible and maxilla.

Methods, devices, systems, and series of appliances are provided for dental implant positioning. One method for positioning an implant with dental treatment includes determining an implant location based on a virtual model of an optimized dental occlusion, moving one or more teeth using a first number of a series of dental appliances, from a first orientation to a second orientation, the second orientation exposing the implant location, placing an implant at the exposed implant location using a landmark included in at least one of the series of dental appliances, repositioning one or more teeth using a second number of the series of dental appliances, from the second orientation to a successive orientation.

Systems, methods, devices and apparatus for mandibular advancement or retraction via bone anchoring devices are described herein. In various aspects, an apparatus for treating a patient via mandibular advancement or retraction comprises a plurality of anchoring devices positioned in the patient's intraoral cavity. Each of the plurality of anchoring devices can be positioned in bone of the patient's upper jaw or bone of the patient's lower jaw. One or more connecting structures can be removably coupled to and extend between the plurality of anchoring devices in order to displace the lower jaw anteriorly or posteriorly relative to the upper jaw.

A method of increasing movement of a tooth in a jaw having at least one tooth with an orthodontic brace thereon includes: (1) holding a handle of a device, the device having an elongate member extending from the handle and a screw tip at a distal end of the elongate member; (2) moving a sleeve along the elongate member to set a length of exposed screw tip; (3) locking the sleeve in place relative to the screw tip; (4) drilling a hole with the screw tip through a cortical bone of a jaw to increase movement of the tooth; and (5) stopping the drilling when the length of exposed screw tip has penetrated the jaw.

A computer-aided method for designing a surgical template for dental and/or orthodontic implants comprises acquiring a first 2D or 3D image of the oral cavity and of the overlying anatomical structures of a patient, processing the first image for defining one or more second 2D images showing corresponding views or sections of the oral cavity, realizing a digital model of the upper dental arch and of the palate of the patient to identify one or more suitable sites for inserting a corresponding implant, selecting one or more slices of the digital model at one or more sagittal or parasagittal planes passing through respective insertion sites, overlapping the slices with corresponding second 2D images for generating a third 2D image, providing a digital library of implants for the selection thereof and for their virtual positioning into the third image in order to allow the adjustment of the inclination and/or the deepness of insertion. A surgical template for dental and/or orthodontic implants suitable to be manufactured with the above method.

An orthodontic correction system is disclosed for correcting Class II malocclusions, Class III malocclusions, dental asymmetries and/or dental related skeletal anomalies in which the patient's dentition is permanent or near permanent. The correction system attaches to a patient's dentition via a novel orthodontic appliance that is affixed to, e.g., pre-installed upper and lower archwires. The correction system includes one or more adjustable length assemblies each of whose ends pivotally attach to a patient's preinstalled maxillary and mandibular archwires. Each pivot is a ball hinge comprising a spherical head that pivotally attaches, allowing the alignment assembly to have free excursion, motion, and/or rotation along multiple axes.

A medical device includes a shaft portion with a hollow shape and inflected portions or an exposed portion. The shaft portion is inserted into a cortical bone or penetrates through the cortical bone and is inserted to a position reaching a cancellous bone at an inner side of the cortical bone. The inflected portions are inflected to radial direction outer sides from one end portion of an axial direction of the shaft portion, and are exposed at a surface of the cortical bone. The exposed portion includes a portion that extends to the radial direction outer side from the one end portion of the axial direction of the shaft portion, and is exposed at the surface of the cortical bone.

An orthodontic device for displacing a tooth and/or a group of teeth of a patient, which directly adjoin the tooth along a mandibular arch, in particular in the lower jaw in the area of the molars, the device comprising: a rigid, dimensionally stable connection between the tooth to be displaced and an attachment point for the device which fixed to the jaw and substantially does not change during the treatment of the patient, a regulating device for changing the length of the rigid connection in direct vicinity of the tooth to be displaced. A torsion-proof attachment of the device in the jaw bone may be provided. Alternatively, a point of support is provided on one tooth.
