  • Patent number: 7654824
    Abstract: An extension piece (2) for a dental implant (1) has a head part (20) which serves as a basis for a retention element (7). The extension piece (2) can be screwed in the dental implant (1) with a threaded stem (29). The extension piece (2) is provided with a reference surface (24) via which the position of the extension piece (2) in the circumferential direction can be transferred to a transfer aid (4) having a transfer surface (42) shaped to complement the reference surface (24). The position of the extension piece (2) is transferred via the transfer aid (4) into an impression (93). The extension piece (2) is then provided with a manipulation implant (5) and is repositioned in the impression (93). From this, a working model (M) is formed in which the desired shape of the extension piece (2) can be defined. The extension piece (2) which has been machined to the desired shape is then screwed into the implant (1) with the same torque as is used for taking the impression.

  • Publication number: 20090136575
    Abstract: The present invention relates to a new and improved low-concentration formulation of an active enamel substance, such as an enamel matrix, enamel matrix derivative and/or an enamel matrix protein, intended to be used as therapeutic, as propylacetic and/or as cosmetic agent. In the present invention, said active enamel substance is incorporated into a polymeric matrix, which is either suitable for cellular in-growth, or cell-occlusive. The active enamel substance can be incorporated into the polymeric matrix so that it is released by degradation of the polymeric matrix, by enzymatic action and/or by diffusion. Comprised in the invention is thus in particular a new pharmaceutical and/or cosmetic formulation of an active enamel substance at a lower total concentration within the formulation, wherein a spatial and/or selective regulation of release of said active enamel substance permits a greater percentage of the active enamel substance to be released at the time of appropriate cellular activity.
