A dental appliance seating tool is configured for a person to bite and provides sufficient resistive force to aid in seating of a removable dental appliance. The seating tool includes top and bottom surfaces configured to respectively engage with top and bottom teeth of an individual. The seating tool also includes a front surface coupling the top surface to the bottom surface and a rear surface opposite the front surface. An interior wall defines a cavity within the volume defined by the top, bottom, front surface, and rear surfaces. The cavity has a front opening in the front surface and a rear opening in the rear surface. The cavity allows a shaft to pass through the front and rear openings, thus enabling the dental appliance seating tool to slide along the shaft.

A mouth piece removal tool. The mouthpiece removal tool includes an elongated handle having a first end opposite a second end. A first hook extends perpendicular from the second end of the elongated handle. The first hook includes a pointed tip curving upwards.

The present invention relates to orthodontic brackets designed for use with the deciduous teeth and method for its use. The brackets provide one or more debonding tabs which reduces the potential for damage to the deciduous tooth due to the application of excessive force during the debonding process. The small size of the brackets allow the brackets to fit available crown space on the deciduous teeth. Further the brackets are shaped to minimize mechanical forces applied to the deciduous teeth when engaged with an archwire. The bracket bases are shaped to conform to the morphology of the deciduous tooth crown surface thereby providing an optimal adhesive interface with the deciduous tooth. The deciduous brackets provide proper adhesion to avoid unwanted detachment of the brackets which often occurs when the use of permanent brackets is attempted on the deciduous teeth.

A method for generating a digital model of dentition, executed at least in part by a computer, acquires a 3-D digital mesh that is representative of the dentition along a dental arch, including includes braces, teeth, and gingival tissue. The method modifies the 3-D digital mesh to generate a digital mesh dentition model by processing the digital mesh and automatically detecting one or more initial bracket positions from the acquired mesh, processing the initial bracket positions to identify bracket areas for braces that lie against tooth surfaces, identifying one or more brace wires extending between brackets, removing one or more brackets and one or more wires from the dentition model, and forming a reconstructed tooth surface within the digital mesh dentition model where the one or more brackets have been removed. The modified 3-D digital mesh dentition model is displayed, stored, or transmitted over a network to another computer.

A handling device for a dental tool having a) a body having an elongated shape configured to receive a prying load from an operator; and b) one or more receptacles through the body configured to retain at least a portion of a dental tool and allow an engagement portion of the dental tool to project therefrom substantially perpendicular to a longitudinal axis of the body; wherein the engagement portion is adapted to contact a portion of a dental covering along only one of a facial side or a lingual side of the dental covering and by being wedged between a gum-line and the dental covering; and wherein the one or more receptacles are configured to transfer the prying load from the body to the engagement portion of the dental tool.

A pocket orthodontic bonding pad for attaching orthodontic attachments to teeth wherein the orthodontic attachment is mechanically secured within a bonding pad pocket with a design that allows a slight buffering flexibility under masticatory stress and ease of removal of the orthodontic attachment. Upon removal of locking tabs the orthodontic attachment may be removed with minimal force, and the remaining bonding pad polished from the teeth with ease, which is most advantageous for brackets that tend to break upon removal and create high stress forces upon tooth structure. The ease of removing orthodontic attachments allows maximum bonding strengths.

An overbite correction device for use on an upper incisor or canine tooth is provided. The device has a bracket body including two rounded lingual protrusions, and a vertical slot therebetween; and a base for bonding to the upper incisor or canine tooth at a lingual side thereof by means of a bonding pad. The two curved lingual protrusions feature a curved lower-facing surface for receiving an incisor, to prevent incisor interference during grinding. The device may feature an aperture for receiving an elastic thread or metal ligature to tie multiple overbite correction devices together. Advantageously, if one device breaks off from a tooth, it is not ingested.

The invention is directed to a composition that safely removes a cured dental cement or resin from metal brackets, metal braces, and enamel surfaces of teeth. It contains eugenol, isoeugenol, methyl-eugenol or an isomer thereof. A method for removing orthodontic fixtures adhered with a dental cement or resin to the enamel surfaces of teeth from these surfaces by contacting the dental cement or resin with a composition containing eugenol.

An orthodontic button has a base for bonding attachment to a tooth. A substantially vertical slot extends into the outer face of the button, and divides the button into a smaller lateral segment covering a smaller portion of the base and a larger lateral segment covering a larger portion of the base. A post on the larger lateral segment provides a point of attachment for removably engaging an elastic to the button. Exerting a lateral compressive force on the smaller lateral segment and the larger lateral segment compresses the slot and releases the base from the tooth.
