1. A system for designing at least one dental restoration for tooth crowns, said system comprising:
a display;
means for acquiring and displaying a three dimensional model of the dental restoration;
means for displaying a plurality of control points, each of the control points corresponding to a respective location on the three dimensional model of the dental restoration, and each of said control points enabling manual customization of the dental restoration model; and
means for displaying an arrow or a grid at at least one of the control points, if an arrow, then a length of said arrow determined by a user defined value, whereby a distance between the dental restoration model and neighboring objects is indicated; and, if a grid, then a size of said grid determined by a user defined value, whereby the distance between the dental restoration model and neighboring objects is indicated [ ,
wherein the arrow or the grid of a control point is only displayed when said control point is activated] .
22. A computer program product having a non-transitory computer readable medium, said computer program product providing a system for designing at least one [ two ] dental restoration [ restorations] , said computer program product comprising means for carrying out the steps of:
acquiring and displaying a [ two ] three dimensional model [ models ] of the [ two ] dental restoration [ restorations simultaneously] ;
displaying a plurality of control points, each of the control points corresponding to a respective location on [ a dental restoration model of ] the [ two ] three dimensional model [ models ] of the dental restoration [ restorations] , and each of said control points enabling manual customization of the [ respective ] dental restoration model; and
displaying an arrow or a grid at at least one of the control points, if an arrow, then a length of said arrow determined by a user defined value, whereby a distance between the dental restoration model and neighboring objects is indicated; and, if a grid, then a size of said grid determined by a user defined value, whereby the distance between the dental restoration model and neighboring objects is indicated [ ,
wherein only the control points of one dental restoration model of the two dental restoration models closest to a mouse cursor are visible] .
