An apparatus for conducting oral care experiments with enamel block substrates (140) and a method of forming and using the same. In one aspect, the invention can be an apparatus for conducting oral care experiments comprising: a plate having a first major surface (111) and a second major surface (112); a handle (170) coupled to and extending from the plate; and at least one enamel block substrate mounted on the first major surface of the plate.

A method for monitoring the positioning of the teeth including production of a three-dimensional digital initial reference model of the arches of the patient and, for each tooth, definition, from the initial reference model, of a three-dimensional digital reference tooth model; acquisition of updated image of at least one two-dimensional image of the arches in actual acquisition conditions; analysis of each updated image and production, for each updated image, of an updated map; optionally, determination, for each updated image, of rough virtual acquisition conditions approximating the actual acquisition conditions; searching, for each updated image, for a final reference model corresponding to the positioning of the teeth during the acquisition of the updated image, for each tooth model, comparison of the positionings of the tooth model in the initial reference model and in the reference model obtained at the end of the preceding steps to determine the movement of the teeth.

A dental implant organizer case includes a housing with a plurality of compartments selectively arranged therein. Each compartment includes: a respective lid pivotally mounted to the housing to cover the compartment's cavity when closed; means for biasing the lid from the closed to the open position; means to releasably secure the lid in the closed position; means to releasably support dental implant containers within the compartment in an upright position; and a respective tooth number marking to indicate the tooth intended for the implant containers therein. The selectively arranged compartments may form a semi-circular or an in-line arrangement. Two compartment levels may be utilized, with the lower compartments being accessible using a tray being slidable with respect to the housing. Two cases may be secured together to be pivotable between collapsed and extended positions, where the first and second cases store dental implant containers for left-hand and right-hand teeth, respectively.

A shade matching method for a tooth obtains a plurality of digitized tooth shade references, obtains a three-dimensional (3D) surface representation of a tooth and associated color information defined on the three-dimensional (3D) surface, selects a region on the three-dimensional (3D) surface representation of the tooth, determines a plurality of correspondences with the common tooth shape of all the tooth shade references, computes color difference with each of the tooth shade reference from the plurality of tooth shade references, and records the label corresponding to the shade reference with a smallest difference.

A method and system for producing, marking, and packaging ingots for use in fabricating dental prosthetics.

A method and system for producing, marking, and packaging ingots for use in fabricating dental prosthetics.

A method and system are presented for measuring the whiteness of teeth. This is accomplished by analyzing an average pixel value of teeth taken from a digital image. The pixel value is mathematically standardized to create an indicator that quantifies teeth whiteness. This eliminates subjectivity in measuring teeth whiteness and permits precise communication of the level of teeth whiteness.

Gingiva indexing devices and methods with various defined red colour regions have a colour grey card or grey card assigned to it for detecting the gingiva status, in particular for producing a gingival restoration. The devices and method comprise an analysis of at least one region of the gingiva status with regard to its shades of red, the position of the shades of red, the colour profile of the shades of red, their geometry and/or their morphology. The analysis can take place manually and/or digitally, and gingiva information is obtained, in particular in the form of a gingiva map, and optional production of a virtual or real model of a gingival restoration as a reproduction of the missing part of the gums and/or part of gingiva.
