The invention relates to a method for restoration of a patients tooth. An electronic image of a patients tooth or tooth preparation is generated in a dentists office by the dentist. The image includes color information of the tooth preparation or of the patients tooth shade. The electronic image is forwarded to a dental laboratory by direct computer link or e-mail. A technician at the laboratory evaluates the image and suggests restorative options to the dentist, including whether further tooth preparation is required. The technician also selects the appropriate restoration tooth shade(s) so that the dental prosthesis matches the color of the patients tooth. The laboratory then manufactures the prosthesis utilizing a plurality of porcelain coatings. If desired, an image of the prosthesis can be generated in the laboratory and forwarded to the dentist for verification of color and/or fit prior to finalizing manufacture of the prosthesis.

An interactive dental restoration method and system for use between a dentist and a dental restoration laboratory. The method includes identifying a dental restoration need in a patient; designing a preliminary treatment plan that includes design criteria for preparation of a dental prosthesis to be placed in the patient to satisfy the dental restoration need; transmitting the preliminary treatment plan via a communications network to a dental restoration laboratory; and communicating a final treatment plan, including modifications to the preliminary treatment plan where necessary, to the dentist. The system includes a computer-based dental restoration system of a network server having a database storing information about materials, procedures and preparations concerning dental restoration prostheses; a communications network providing access to the network server; and one or more computers at a dental office accessing information stored at the database over the communications network and displaying the information in a humanly readable format. Preferably, the communications network is the Internet, and the information stored in the database comprises preparation diagrams, reduction dimensions, margin design and burs for specific dental restoration prostheses. Typically, the final treatment plan includes information about materials for preparing a dental prosthesis that satisfies the design criteria, and the dental prosthesis is then prepared for placement in the patient.

A digital camera connects to a tooth shade analyzer subsystem, e. g. , a digital video processor, and a color display monitor for the electronic determination of the color of patient's teeth. Preliminarily, the camera captures series of digital color images of tooth shades corresponding to reference shade guides, and electronically compares the reference shades to an image of the patient's tooth. In a preferred embodiment the comparison is done over a set of pseudo-pixels, each corresponding to a group of pixels in an high-resolution camera. Once a match is found, it is communicated to a user of the system. In a specific embodiment the camera is equipped with a sleeve and illumination subsystems that help reduce the variations in the color of digital images due to external factors.

The invention relates to a computer readable medium that includes one or more programs for carrying out a method for restoration of a patient's tooth. The method includes the steps of generating an electronic image of a patient's tooth; providing a preliminary treatment plan for addressing the dental needs of the patient; and forwarding the electronic image and preliminary treatment plan to a dental laboratory so that technician can evaluate the image and treatment plan and in a manner such that the technician and dentist can review and discuss the preliminary treatment plan.

The invention relates to a method for determining a patient's tooth shade that includes the steps of electronically imaging a patient's tooth to obtain an image which includes color information representative of tooth color; determining the patient's tooth color from the color information of the image; and displaying the determined tooth color to identify one or more tooth shades having a combined color corresponding to the determined tooth color. Preferably, the displayed data includes RGB chromaticities of the color image, and the patient's tooth color is determined by averaging the color information at selected locations of the image which correspond to different spatial locations of the patient's tooth. If desired, the color information of the patient's tooth can be electronically stored for use at a later time.

The invention relates to a method of determining a tooth shade of at least a portion of a patient's tooth which is to be replaced or restored, by capturing an electronic image of the patient's tooth, the image including color information representative of the patient's tooth shade; storing color information representative of known tooth shades with each known tooth shade representing a different tooth color; calibrating the color information of the patient's tooth and the color information representative of known tooth shades; and comparing the color information of the patient's tooth with the stored color information to identify a single tooth shade or a combination of tooth shades with a color or combined color corresponding to the color of at least a portion of the patient's tooth, such that the patient's tooth may be comprised of a single tooth shade or a plurality of tooth shades.
