73862381

Abstract:

A system and method for concurrently measuring a force exerted upon a tooth is disclosed. In one aspect of the invention, the system includes a target tooth attached to a force gauge which is coupled to a motion module for adjusting the tooth to a reference position. The method includes utilizing a motion module of a force measurement device is utilized to adjust each target tooth of a plurality of target teeth to be located in a reference position.

US Classification:

206083000

Abstract:

A container for transporting set of three-dimensional dentition models includes an outer shell containing a shock-absorbing core, wherein the core includes compartments configured to receive separately a bite registration and upper and lower dental arch models. The shell and core are preferably transparent to a pre-selected scanning radiation A method of transporting and processing a set of dentition models includes the steps of (a) providing a container having an outer shell and an inner shock-absorbing core configured to hold a bite registration and upper and lower dental arch models in separate compartments; (b) loading the bite registration and the dental arch models into their respective compartments; (c) transporting the container to a processing site; and (d) processing (e.g., by scanning) the dental arch models and the bite registration while they are in the container. The container containing the dental arch models and the bite registration may then be stored.

US Classification:

106 35, 206219, 206568, 206 635

Abstract:

A dual-chamber package for the constituent materials for preparing an alginate dental impression paste includes a first chamber containing a pre-measured volume of water, and a second chamber, attached to and isolated from, the first chamber, and containing a pre-measured quantity of alginate powder, wherein the quantity of powder and the volume of water are in a pre-determined ratio for making a dental impression paste when mixed together. The powder and the water may be mixed outside of the package by dispensing the water and the powder respectively from the first and second chambers. Alternatively, the powder and water may be mixed within the second chamber by breaching a barrier between the first and second chambers to allow water to flow from the first chamber into the second chamber, after which the alginate dental impression paste is dispensed from the second chamber.

US Classification:

257774, 438113, 257E23011, 257E21599

Abstract:

A low cost and high performance flip chip package is disclosed. By assembling the package using a substrate panel level process, a separate fabrication of a substrate is avoided, thus enabling the use of a coreless substrate. The coreless substrate may include multiple stacked layers of laminate dielectric films having conductive traces and vias. As a result, electrical connection routes may be provided directly from die contact pads to package contact pads without the use of conventional solder bumps, thus accommodating very high density semiconductor dies with small feature sizes. The disclosed flip chip package provides lower cost, higher electrical performance, and improved thermal dissipation compared to conventional fabricated substrates with solder bumped semiconductor dies.

Abstract:

An orthodontic alignment device can have a palatal contour anchorage (PCA) feature that generally matches the shape of the patient's hard pallet. This PCA feature may be built slightly off-set to deliberately push against the patient's palate and/or gingiva to provide anchorage support of staged translation of the teeth. By transferring the required anchorage away from the teeth and onto the palate, through the PCA feature, the adjacent teeth are no longer subjected to unwanted side effects of reaction forces.
