Provided is an occlusal pressure analysis program capable of improving the accuracy of grasping the occlusal contact state in occlusal pressure acquisition by a pressure detection means, including a step of obtaining a pressure value for each minimum unit from which the pressure value can be recognized by a pressure detection means, and a step of, regarding each of the minimum units where the pressure value exists as a detection unit, separating the detection units into the detection units which can be regarded as due to occlusion and the detection units which are unclear whether they are due to occlusion, based on the pressure value.

A method includes determining depth values associated with a first set of pixel locations in a first image of a mouth. One or more function is generated for one or more color channels based on intensities of the one or more color channels at the first set of pixel locations and depth values associated with the first set of pixel locations. Image data comprising a new representation of the teeth is received, wherein the image data comprises a second set of pixel locations and new depth values associated with the second set of pixel locations. A new image is generated based on the image data and the one or more functions.

A bone drill bit includes a metal drill shaft body. The metal drill shaft body includes a drilling section, a clamping section, and a passive temperature-sensitive optical indicator which is in a thermo-conducting connection to the metal drill shaft body.

The invention relates to a dental ceramic blank, in particular a filled milling blank, comprising at least one organic Compound, such as a polymer polymerized in the blank, for improving the machining properties of the blank. The blank has an open-pore ceramic microstructure which has 2 to 50 wt. %, based on the total composition of the dental ceramic blank, of at least one organic Compound. The invention also relates to a method for producing the blank. The milling blank according to the invention clearly exhibits improved material properties compared to unfilled purely ceramic milling blanks which have been milled into blanks for molded prosthetic parts in CAD/CAM methods

A method of monitoring the degree of fit of an aligner among a series of aligners includes the steps of selecting an aligner in the series of aligners whose fit to a patient's teeth are to be tested to determine its fit with the selected aligner; disposing a nontoxic colored plastic material into the selected aligner; setting the patient's teeth into the selected aligner containing the material; and determining the amount of material disposed onto the interior aligner's surfaces by visual inspection by assessment of the material disposed therein, a good fit being indicated by a minimum of material extruded onto almost all of the interior aligner surfaces and by a light color, and a poor fit being indicated by an excess of material extruded onto one or more locations of the aligner interior surfaces and a dark color.

A method of making a dental restoration has the step of providing a precursor of the dental restoration. The dental restoration has at least a first and a second surface portion which are delimited by a physical boundary structure. The method further has the steps of applying a first coloring solution associated with the first surface portion onto the first surface portion, sintering the dental restoration precursor, and removing the physical boundary structure.

An oral hygiene device is provided. The oral hygiene device includes a body having a base and first and second opposing sides extending from the base and defining a gap there between. The device may further include a plurality of corresponding notch pairs, wherein each corresponding notch pair has a first notch positioned in the first opposing side and a second notch positioned in the second opposing side. The location of the notch pairs may coincide with a user's mouth and in particular to the position of the user's teeth within the mouth. As such, a fibrous material, such as floss, may be coupled to the device such that the material spans the gap between at least one of the corresponding notch pairs so that the material may be inserted into the spaces between the user's teeth when the device is placed into the user's mouth.

The present disclosure relates to a labelled root canal filling material. The labelled root canal filling material according to the present disclosure is filled in a root canal to perform root canal treatment, and includes a main body having a shape corresponding to a shape of the root canal to be filled in the root canal and to be removed by a cutting tip after being inserted into the root canal; and a remaining portion integrally formed with the main body, having a mark to be distinguished from the main body, and remaining in the root canal when the main body having inserted into the root canal is removed by the cutting tip.

The present disclosure relates to a ceramic structure for dental application, preferably dental restoration, process for obtaining it and its uses. The process now disclosed comprises computer-controlled machining (CNC), particularly by milling, to obtain a ceramic structure, for example dental covers, which reach thicknesses between 0.05 and 0.4 millimeters.

A computer-implemented method for marking an object on an aligner. The aligner surface is modeled. The method includes calculating a normal for each tile in a tessellated surface and disqualifying a tile from being selected. For tiles not disqualified, a patch is identified that produces a markable area. The method includes selecting an object to be marked, calculating a location of the object in the markable area, and providing the location of the object to a marking device. Disqualifying includes comparing an angle between a normal and an orientation of the beam to an origin of the calculated normal on each tile. Disqualifying includes disqualifying the at least one tile when the angle is outside of a range of 90 to +90. Identifying the patch includes separating the patch into at least two smaller patches, and one of the two smaller patches of tiles is the markable area.
