  • Publication number: 20130282351
    Abstract: The invention describes a method of determining virtual tooth restorations on the basis of scan data (D) of oral structures, wherein a model database (DB) comprising a number of parameterized tooth models for each of several tooth types is used, whereby the parameterization is carried out on the basis of model parameters comprising position parameters and/or shape parameters and whereby each tooth model (M) is linked with a number of tooth models (M) of the same tooth type, and wherein, for each desired tooth type, an optimal tooth model (M) in the model database (DB) is determined by means of an iterative method in which initially at least one start tooth model (M) of the desired tooth type is selected from the model database (DB), and subsequently, commencing with this start tooth model (M), in each iteration step (S) a tooth model (M) is tested with regard to a quality value, wherein for individualization, the tooth model (M) currently in test is adjusted to the scan data (D) by varying model parameters an

  • Publication number: 20130230825
    Abstract: A holding device for retaining and transporting a dental implant, particularly a dental implant stored in an ampule having preserving fluid, is provided. The holding device has a securing section, which has a force transmission element for rotationally securing the dental implant and an attachment element having one or more resilient arms formed integrally with and distally of the force transmission element, for longitudinally retaining the dental implant. The resilient arms do not extend beyond the radial perimeter of the force transmission element. The resilient arms can be transformed between a first operative configuration and a second compressed configuration under forces during operation, to allow a radially enlarged end of the arms to releasably engage an undercut of the dental implant.
