Abstract

A customized lingual orthodontic bracket and a manufacturing method thereof, the lingual orthodontic bracket comprising a bracket body (10) in a ball coronary shape jointly defined by a teeth-facing surface and a tongue-facing surface. The middle area of the tongue-facing surface of the bracket body (10) has a recessed part (11), and an upper limb (12), a lower limb (13) and a groove (14) are provided inside the recessed part (11), the tongue-facing surface of the bracket body retaining a circular profile with the external surface of the upper limb (12) and the lower limp (13). The manufacturing method of the bracket is to establish a virtual bracket body (10) in a computer and to set a center line (40) of the groove (14), acquire a tooth arrangement model of an ideal dentition and to determine a virtual placement position of the groove (14), match the center line (40) of the groove with the virtual placement position of the groove (14), rotate the bracket body (10) to adjust position and thickness about the center line (40), and finally, cut out the groove (14) along the center line (40), and print via 3D to generate a real bracket. The tongue-facing surface of the whole bracket body (10) is manufactured as an arc shape, dramatically reducing stimulation to the tongue and increasing comfort for a patient.

Abstract

Disclosed is a personalized lingual self-locking orthodontic appliance, comprising several lingual self-locking brackets and an arch wire for connecting the individual lingual self-locking brackets in series. The lingual self-locking brackets each comprise a base plate (1) fitting with a corresponding tooth position lingual surface and a bracket body (2) fixedly connected to the base plate (1), a lock cover (3) is hinged on the bracket body (2), the lock cover (3) is hinged on the bracket body (2) through an elastic shaft (221), and a locking slot (21) is arranged on the bracket body (2) and used for locking the tail end of the lock cover (3). Using this personalized lingual self-locking orthodontic appliance, the several bracket bodies (2) are connected in series through an arch wire, and the base plates (1) at the bottom of the bracket bodies (2) are made of a flexible metal, and during the series connection process, the self-locking of positions of each bracket body relative to the arch wire is realized by locking the lock covers (3) in the locking slots (21). The position of each bracket body of this self-locking orthodontic appliance has a better flexibility, which can effectively improve the comfort of a patient and is also convenient for doctors during clinical operations.

Abstract

A lingual straight wire dental appliance is provided. Brackets (1) of anterior teeth and brackets (2) of posterior teeth, which are attached on the lingual side of anterior teeth and the lingual side of posterior teeth respectively, are made with surfaces coinciding with anatomical surfaces of lingual side of teeth of a patient so that the brackets are fixed more stably. Meanwhile, an arch wire (3) of anterior teeth is configured with a curved shape and an arch wire (4) of posterior teeth is configured as a straight arch wire to facilitate the teeth to move during growth. Due to a bent portion (6) of arch wire is provided between the arch wire (3) of anterior teeth and the arch wire (4) of posterior teeth, the appliance is installed more tightly so that the better effect on the teeth with need of correction is achieved and discomfort of patient during correction treatment can be reduced at the same time.

Abstract

A personalized orthodontic appliance having an orthoaxis function, which comprises No.1 to No.7 personalized orthodontic lingual brackets connected in series with each other by an arch wire (5). Each personalized orthodontic lingual bracket comprises a bottom plate (3) and a bracket body portion (2) connected with the bottom plate (3). Among the No.1 to No.7 personalized orthodontic lingual brackets, traction hooks (1) with through holes (11) are arranged on the lower sides of the bracket body portions (2) of at least two personalized orthodontic lingual brackets, and the through holes (11) are connected together in series through an orthoaxis wire (4). The traction hooks (1) with the through holes (11) are arranged on the lower sides of the bracket body portions (2) and the orthoaxis wire (4) penetrates through the through holes (11), so that corresponding orthodontic force is produced on the lower sides of the bracket body portions (2) while the dental crown moves in the orthodontic process, thereby gradually correcting the positions of the roots of teeth and avoiding the inclination of teeth in the distal movement process; therefore, the personalized orthodontic appliance has the orthoaxis function. Besides, the personalized orthodontic appliance is simple and smart in structure, good in orthoaxis effect, and thus suitable for dental extraction cases in personalized orthodontic therapy.

Abstract

Disclosed is an arc wire bending clamp, comprising a fixing and clamping unit (1, 11) and a rotating unit (2, 21) connected to each other. The rotating unit is capable of rotating around the fixing and clamping unit. After determining a bending point of an arc wire (6), the bending point is fixed by the fixing and clamping unit, and the rotating unit rotates to press the other end of the arc wire so that the arc wire is bent and deformed. The bending point varies in turn, and a customized arc wire can be manufactured. The clamp has a simple structure and is easy to operate.

Abstract

A method for manufacturing a positioning tray and a bracket with a positioning hook for manufacturing the positioning tray. The method for manufacturing the positioning tray comprises the following steps: acquiring an original dental impression and an ideal dental impression; transforming the ideal dental impression to a three-dimensional digital model and drawing each bracket body; drawing a positioning hook on the bracket body; making a wax pattern of a bracket with the positioning hook by using a wax pattern machine; casting, with the wax pattern as a mould core, a blank of the bracket with the positioning hook which then receives surface treatment; after the surface treatment, assembling the bracket with the positioning hook to the original dental impression and performing film lamination to obtain a positioning tray, and finally removing the positioning hook to obtain the bracket matching the positioning tray. The bracket with the positioning hook is manufactured for implementing the method. It is unnecessary to make an integrated model of the bracket and dental impression, which greatly reduces the production cost. Moreover, a finished appliance can be obtained after cutting off the positioning hook, and it is unnecessary to cast a separate bracket additionally, thereby saving costs and shortening the production cycle.
