A system for repositioning teeth comprises a plurality of individual appliances used with braces. The appliances are configured to be placed successively on the patient's teeth and to incrementally reposition the teeth from an initial tooth arrangement, through a plurality of intermediate tooth arrangements, and to a final tooth arrangement. The appliances may be substituted with braces as appropriate to optimize the treatment of the teeth.

Kits, apparatus, devices and methods for treating varicose veins caused by an incompetent venous junction (e.g., the saphenofemoral and / or saphenopopliteal junctions) are disclosed. The kits may include a sheath, a vein closure device, and an injection device. Alternatively, a vein closure device may include an integral injection channel and injection device. Methods may include injecting a vein with a sclerosing agent through a needle that extends in a direction that is not aligned with a longitudinal axis of a sheath or shaft.

Systems and methods of generating updated surgical plans are described herein. In one embodiment, a method of generating an updated surgical plan can include generating a three dimensional (3D) model of a bone, generating a surgical plan based on the 3D model, in which the surgical plan can include: locations on the bone upon which to dispose a fixator and settings of struts of the fixator, disposing the fixator on the bone based on the surgical plan, and, based on data associated with the placement of the fixator disposed on the bone, generating an updated surgical plan including updated settings for the struts.

The invention discloses a digitalized making method of a dental orthodontic appliance. The digitalized making method comprises the steps of acquiring CT (Computed Tomography) data and carrying out intraoral scanning; reconstructing a three-dimensional oral tissue model to obtain bones and teeth; reconstructing intraoral scanning data to obtain gingivas and accurate teeth; compounding two models to obtain a composite model; calculating key parameters including tooth movement amount, required orthodontic force and moment, and force applying mode and the like, discharging a treated target dentition; accurately calculating a mode of moving each tooth and a movement distance or an angle, calculating a required force and moment; calculating required shape and size parameters of an SMP force applying mechanism, and further designing a force applying unit; generating an immobilizing structure according to the three-dimensional model of each tooth on the basis of the surface; designing accessories according to certain special movements so as to obtain an integral structure of an integrated orthodontic appliance; making an integrated orthodontic appliance by using a three-dimensional printer integrally formed from multiple materials, and providing the integrated orthodontic appliance for being clinically used by a doctor; and during clinical use, heating the integrated orthodontic appliance to a phase change temperature to ensure that the force applying unit becomes soft and is conveniently adhered and fixed on the surface of the tooth. An integrated fixed appliance manufactured by using the method comprises a force applying unit, an immobilizing unit and accessories.

A particle beam irradiation apparatus includes: a beam generation unit that generates a particle beam; a beam emission control unit that controls emission of the particle beam; a beam scanning instruction unit that sequentially two-dimensionally instructs a position of the particle beam so that the particle beam is scanned across the entire slice; a beam scanning unit that two-dimensionally scans the particle beam; a respiration gate generation unit that generates a respiration gate synchronized with a respiration cycle of the patient; and a pulse generation unit that generates a predetermined number of scanning start pulses at substantially equally spaced time intervals in the respiration gate. The beam scanning instruction unit instructs to scan the entire slice by pattern irradiation based on a set dose from each of the scanning start pulses so that a scan of the same slice is repeated the predetermined number of times.
