A method for analyzing a dental impression including receiving, by a dental impression review computer system, an image of a first dental impression administered by a user of the user's teeth, analyzing, by the dental impression review computer system, the image of the first dental impression, and providing, by the dental impression review computer system, feedback to the user based on the analysis.

A method can include applying a clear or mostly clear dental coating on one or more teeth for preserving the structure and/or appearance of the one or more teeth. The method can include bleaching the one or more teeth before applying the clear or mostly clear dental coating.

A digital dental tray system is described including a dental tray shaped to at least partially surround a plurality of teeth and a plurality of three-dimensional (3D) optical imaging elements attached to the dental tray. Each of the 3D optical imaging elements comprises a structured light projector to project a light pattern onto one or more teeth of the plurality of teeth and a camera to capture an image of the one or more teeth.

The invention relates to a method and kit for preparing a dental device. The method includes the steps of: (a) providing a dental impression kit to a user; (b) receiving a dental impression from the user from the dental impression kit; (c) digitizing each dental impression to form a three dimensional image; (d) merging the digitized images to form a three dimensional image of the arch; and (e) manufacturing a dental device from the three dimensional image of the arch.

A scannable dental spatial orientation device can comprise a coupling feature operable to couple with a bite plate for supporting a physical dental record material. The scannable dental spatial orientation device can also comprise a body portion having first, second, and third planar faces oriented orthogonal to one another. In addition, the scannable dental spatial orientation device can comprise at least one joint configured for rotating the bite plate and the body portion relative to one another to align the first, second, and third planar faces parallel to a sagittal midline reference plane, a horizontal plane, and a frontal plane of a patient. A dental record optical scan system and a method for digitally recording a maxillary arch position are also disclosed.

The present invention is a digital custom denture impression tray that includes an upper U-shaped plate to measure the shape of a patient's upper gum having missing teeth and normal teeth arranged therein; a lower U-shaped plate to measure the shape of the patient's lower gum having missing teeth and normal teeth arranged therein; a height adjustment unit disposed on the upper plate for measuring the height of the denture to be implanted and structured to adjust horizontality and height of the upper plate and the lower plate; a screw nut attached to the height adjustment unit having a threaded hole at a predetermined depth; a screw bolt having a threaded surface to adjust height by being inserted in the threaded hole from under the screw nut; an indicator teeth disposed on the front center of the upper plate for recording centric relation and guiding the upper plate toward the lower plate; a front corresponding cooperation spot provided on the lower plate for receiving the indicator teeth thereon; and a rear corresponding cooperation spot provided on the lower plate for receiving the screw bolt thereon.

Ablation probe tips (108, 148, 320, 360) and physical and virtual stents (110) for use in tooth bud ablation procedures that result in tooth agenesis as well as tooth bud ablation methods are described herein.

A method of making a dental restoration has the steps of: determining a virtual space available for accommodation of a dental restoration for a tooth to be restored; retrieving a predefined virtual master dental restoration surface from a database; fitting the virtual master dental restoration surface in the space to provide a virtual outer dental restoration surface; creating a virtual inner dental restoration surface independent of a shape of the tooth to be restored; providing a virtual model of a dental restoration based on a combination of the virtual outer dental restoration surface and the virtual inner dental restoration surface; and fabricating the dental restoration based on the dental restoration model.

A oral appliance (i.e., a dental mouth guard) configured so as to fit in the mouth and over at least one (e.g., the upper) set of teeth of a user during sleep to prevent bruxism and the grinding together of the user's upper and lower sets of teeth. The mouth guard has a relatively soft heat responsive and arcuate shaped upper impression tray that is molded over a relatively hard and arcuate shaped lower chassis. The mouth guard is removably received within and transported by a fitting tray to be submerged in boiling water. After it is heated, the fitting tray relocates the mouth guard to the user's mouth where a biting force is applied by the user to the upper impression tray so that an accurate and custom impression of the user's teeth is made therewithin. The mouth guard is now removed from the fitting tray which is then discarded.

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.
