System and method for adding surface detail to digital crown models created using statistical techniques

Generating a crown model using a statistical method (such as k-means clustering, principal component analysis (pca), or similar statistical methods) can result in a crown model that is missing sharpness details below the threshold of the statistical technique. A method is provided to add back the sharpness to the resulting model by combining a single full-featured example into the algorithms generating the statistical model. ... Dentsply International Inc

Support body for a blank

The invention relates to a support body for a blank, whereby the support body possesses a receiving opening for the blank that is surrounded by an inner circumferential surface, which terminates in an upper and a lower edge, and whereby a blank fixed in position within the support body is bonded to the latter by means of an adhesive agent. In order to be able to easily introduce the adhesive agent into a gap between the blank and the support body it is intended that the inner circumferential surface possesses at least one depression and/or elevation extending to accommodate the adhesive agent.. ...

Dental composition

A dental cement hardened by a cement reaction involving the specific polymerizable polyacidic polymer and optionally additional crosslinkable groups, has reduced shrinkage and improved mechanical properties, in particular with regard to flexural strength and fracture toughness. Moreover, the specific polymerizable polyacidic polymer of the present invention contains a high number of acidic groups which is not reduced by the presence of polymerizable moieties, whereby water solubility of the uncured polymer is not impaired by the presence of the polymerizable moieties.. ... Dentsply International Inc

Improved cervical matrix

A universal cervical matrix for dental use comprising a lamina having at least an outer layer and an inner layer, the inner layer comprising a non-stick surface to prevent adhering to a chemically-cured dental restoration material, and the outer layer comprising an energy-absorbing material. The energy-absorbing material absorbs energy output from a dental curing light and provides heat to the dental restoration material, thereby increasing curing rate.. ... Dentsply International Inc
