A tongue (30), directed toward the occlusal wall (6), is cut out from the lingual leg (26) of the clip (25) and is bent off in the labial direction so that an acute angle is enclosed between the tongue and the lingual leg (26) of the clip (25).

An adjustable orthodontic bracket including an body member for fixing orthodontic arch wire in a position such that a predetermined stress is generated and applied to the tooth to be treated; a bonding base member for bonding the bracket to a buccal or lingual surface of a tooth to be treated; and a bendable element, wherein the bendable element connects the body member to the bonding base member. The body member includes a slot for the arch wire, wherein the bendable element enables to adjust accurate angles of the slot. The bendable element can be rigid or flexible wherein in the flexible form, a holding device is further included. The present invention further provides tools to band and/or rotate the adjustable orthodontic bracket of the present invention.

A facial registration tool for use in the fabrication of dental prostheses includes two or more interconnected artificial teeth and a retention means extending posteriorly from the lingual surface of the teeth for attaching the tool to a wax bite rim. In one embodiment the facial registration tool includes simulated upper left and right lateral and central incisors and a retention knob for mounting the tool to a bite rim.

The invention provides a split type guide plate for accurately positioning an orthodontic bracket. The split type guide plate comprises a tooth occluding part and a buccal surface groove, wherein the tooth occluding part is arranged on a dental crown of teeth, comprises a tooth occluding surface, part of buccal labial surface and part of lingual surface and is matched with a dental body; the buccal surface groove is formed in the buccal labial side of the tooth occluding part; the inner side surface of the buccal surface groove is matched with the side surface of an occlusion part of the orthodontic bracket. The split type guide plate disclosed by the invention has the advantages that quick and one-time bonding of the orthodontic bracket can be realized; a bonding process is simple to operate; a doctor is enabled to simulate the tooth aligning condition on a computer, and then an optimal position and the direction of the bracket are designed according to a simulation result, thereby realizing an effect of inducing the alignment; the repeatable and accurate positioning of each orthodontic bracket can be realized; even if a single orthodontic bracket falls off at later stage and needs to be bonded again, the orthodontic bracket can be accurately positioned at the original position by using an original guide plate; the orthodontic bracket can be matched with brackets of various models in the market.

An orthodontic device-setting tool is provided with: a fitting section having a fitting surface, which covers and fits together with at least one of the incisal margin, the dental cusp, or the occlusal surface of a tooth; a foundation section, which has a back surface that adheres closely to the labial/buccal surface or the lingual surface of the tooth and has, on the surface opposite the back surface, a front face on which the orthodontic device is mounted; and a connecting section that connects the fitting section and the foundation section. The tool has a frame section, which protrudes from the front face of the foundation section and can fit together with the orthodontic device. Use of the orthodontic device-setting tool makes it possible to mount orthodontic devices such as corrective brackets without holding the patient for long periods of time and to mount the orthodontic devices accurately at the desired three-dimensional mounting positions for the orthodontic devices regardless of the skill level of the dentist practitioner. Moreover, the tool can even be used with mass-produced general purpose orthodontic devices, which are not orthodontic devices that have been specially customized as to design, cut, etc. for individual patients.
