A removable orthodontic appliance of discrete plastic sleeves, each being receivable over a corresponding tooth of a patient. Lingual clips are fastened to the corresponding tooth and which are engageable with corresponding structure of the sleeves for removably retaining each of said plastic sleeves to the corresponding tooth of the patient. Buccal brackets are fixably carried on a side of each of the sleeves positionally corresponding to a buccal surface of the corresponding tooth to which each of the sleeves is receivable. An arch wire is ligated to each of the buccal brackets to extend therebetween. The system can be conveniently removed for cleaning and adjustment.

An implant includes an implantable body portion adapted to be at least partially recessed within a patient's alveolar bone, and which has a peripheral surface portion, which is configured to stimulate and / or facilitate the engagement of osteoblasts and other bone tissues with the implant. The implant body provides bone engaging regions along one or more of the distal and / or mesial implant surfaces, which are elongated relative to bone engaging regions on the lingual and / or buccal surfaces of the implant body. In particular, the implantable portion of the implant body includes a bone engaging surface which, when the implant body is fully seated within the patient's jaw bone, extends from a distal portion of the implant body to a remote proximal-most edge. The proximal-most edge has a contour selected to generally follow a predetermined crestal outline of the supporting bone tissue.

A method for producing a dental prosthetic item, including providing a 3D model of the item. The providing includes determining an esthetically relevant designed subregion of a 3D model of the item as part of an exterior surface of the item. The subregion corresponds to a labial surface and / or incisor edge, or to a buccal and / or occlusal surface. Further steps include selecting a suitable blank, specifying a blank having a prefabricated esthetically relevant terminal subsurface of a surface of a tooth, a terminal subsurface of the blank being such as at least approximates the subregion. A further step includes forming the item from the selected blank such that a prefabricated terminal subsurface of the blank remains unmachined in at least a central region thereof. The forming includes machining the blank only in a marginal area of the terminal subsurface and on at least some surfaces outside of the terminal subsurface.

Provided is an apparatus for generating dental data for manufacturing an aligner, the apparatus including: a dental-data generation unit, in which the dental-data generation unit includes a preprocessing module includes a first module that receives data on a current state of the teeth of the patient from a scanner that scans the current state of the teeth of the patient, a second module that generates a state of the teeth of the patient and the vicinity of the teeth as 3D data, based on the data received from the scanner, a third module that sets a central point for dental movement in the 3D data, a fourth module that sets each central reference for a crown, a buccal surface, and a lingual surface of the tooth in the 3D data, and a fifth module that sets a reference for a dental root point in the 3D data.

The invention relates to a device for correcting teeth, in particular to a carrier-arch-wire combined tooth correcting device. The tooth correcting device which is disclosed by the invention comprises a buccal tube, a carrier groove, a tooth arch wire and a ligation device; wherein, arch wire grooves in the medial-distal direction are arranged on the carrier groove and the buccal tube; auxiliary channels which have openings in the arch wire groove are arranged in the side walls of the arch wire grooves of the carrier groove and the buccal tube; the auxiliary channels are in the medial-distal direction; one or more than one of the auxiliary channels respectively start from the medial edges and / or the distal edges of the square side walls and / or the gum square side walls of the arch wire grooves; the medial edge and the distal edge of the side wall of the arch wire groove form acute angles with the bottom wall; thus the ligated arch wires can move in the arch wire grooves. The positions of the tooth arch wires in the arch wire grooves and the entering-in and the coming-out of the auxiliary channels can be controlled through adopting different arch wires and cooperating different ligation modes, therefore not only a light force can move obliquely the tooth along the medial-distal direction, but also the tooth is easy to be rooted along the buccolingual direction and the medial-distal direction without additional arch wires. Moreover, the carrier-arch-wire combined tooth correcting device has simple structure and convenient use.

A direct dental bridge, built in the mouth of a patient, comprising Zirconium oxide or Aluminium oxide reinforcement bars (19, 20) onto which the pontic of the bridge is assembled. The ceramic bars of the present direct dental bridge bond better to dental filling materials and dental bonding resins than metal bars, and are easier to use than fiber ribbons and resin bars. Also disclosed is a method of building a direct dental bridge further comprising the use of a dental material gingival wedge bonded on an abutment tooth, demale molds for surface veneers, malleable gingival veneers and occlusal / buccal surface veneers.

A method and the resulting product for optimizing the configuration of a mouthpiece for cleaning teeth in which the configuration of the mouthpiece is optimized to the oral geometry of individual users. The method includes a first step (26) of producing a digital scan of the oral geometry of the individual user and then producing a rigid shell (30) for the mouthpiece substantially matching the digital scan. The configuration of the resulting mouthpiece is characterized by the outer surface of the shell not extending from the buccal surface of the individual teeth more than 7 mm (31 ); further, by the rear edge of the shell not contacting the tissues to the rear of the rearmost teeth (36), and still further by no more than a 2 mm overlap into the gum line (36), when the mouthpiece is operatively positioned in the user's mouth.

Provided is an anchorage preparation buccal tube having at least two arch tubes for receiving correction arch wire, wherein the axis inclination angle of at least one arch tube is a negative value. The lines of said arch tubes or the projections thereof on the buccal surface intersect with each other. The buccal tube can be designed into having a plurality of cross-arranged arch wire tubes, the physician can insert the correction arch wire into arch tube with suitable angle to recline the molar so as to increase anchorage in different stages according to the anchorage value needed for correction.
