摘要:
Methods, devices and systems for digitizing a patient's arch and manipulating the digital dental arch model. In one variation the methods includes producing a physical arch model for the patient's arch, separating the physical arch model into a plurality of arch model components, mounting the arch model components on a scan plate, capturing one or more images of the arch model components, and developing digital representations of the arch model components using the captured one or more images.
摘要:
Described herein are methods for making highly accurate layered dental models from a cast of a subject's oral cavity (e.g., the upper or lower dental arch) that avoid shrinkage or deformation. The methods may include the steps of sequentially preparing the model-forming material, applying a layer of model-forming material to a cast, and curing the layer before applying the next layer. The model-forming material may include one or more stabilizers (e.g. thermal stabilizers). Dental models having multiple layers are also described.

A dental aligner for producing predetermined movement in a patient's tooth includes a shell-shaped portion including an outer surface and an inner surface to be in contact with the patient's tooth, a bottom portion to be placed near the gingival of the patient's tooth, a tip portion on the opposite side of the bottom portion, and one or more wrinkles formed over at least one of the outer surface, the inner surface, and the bottom portion.
摘要:
A method for moving a subject's teeth in a dental treatment includes moving the subject's teeth toward desired positions by one or more dental aligners. A movement pathway may comprise determining a number of intermediate movement positions on the way to achieving a final configuration. In selecting the movement path, movement in one or more directions may be constrained. Feedback based on the actual position of the subject's teeth during treatment may be used to modify the treatment, including the movement path and aligners.
摘要:
A casting chamber for casting a physical tooth model representing a patient's tooth includes a chamber body and a lid. The chamber body includes a cavity adapted to hold a negative impression of the patient's tooth and to receive a cast material, wherein the negative impression and the chamber body are registered by a registration unit. The chamber lid is configured to seal the cast material in the casting chamber to permit the casting material to solidify in the casting chamber to form a physical tooth model representing the patient's tooth.
摘要:
A system for producing corrective movement in a subject's teeth includes a dental aligner device having one or more through-holes and one or more connectors fixed to the subject's teeth. The connectors can snap into the through-holes when the dental aligner is worn on the subject's teeth.
摘要:
A method for manufacturing wrinkled dental aligner for a patient's tooth includes developing a digital dental aligner model specifying at least one wrinkled surface on a dental aligner and producing a dental aligner having the wrinkled surface in accordance with digital dental aligner model.
摘要:
A physical dental arch model includes an adjustment jig that receives a physical tooth model and enables the rotations of the physical tooth model around at least two separate axes. A base receives the adjustment jig such that the physical tooth model can rotate relative to the base around at least the two separate axes.
摘要:
A method for managing an interaction of a calling party to a communication partner is provided. The method includes automatically determining if the communication partner expects DTMF input. The method also includes translating speech input to one or more DTMF tones and communicating the one or more DTMF tones to the communication partner, if the communication partner expects DTMF input.
摘要:
The invention relates to a system for processing an electromagnetic input signal in which processing circuitry may be used to produce a bounded phase signal, such as by calculating an n-bit 2's compliment number in the range of [−1, 1] from phase sample information for an input wave; and producing an unwrapped phase difference signal from the bound phase signal, such as by taking a 2's compliment subtraction using another wrapped phase signal from previous phase sample information. A corrected phase signal may also be used by taking a 2's complement addition using the bounded phase signal, wherein the unwrapped phase difference signal is produced using the corrected phase signal.
