Abstract
Disclosed is a computer-implemented method for selecting tool heads for a tooth preparation comprising a removal of tooth material. The method comprises receiving a three-dimensional digital initial tooth model and a three-dimensional digital target tooth model. Definitions of tool heads of a plurality of tool heads of a plurality of tool kits are received. It is checked for different combinations and sequences of usage of the tool heads, whether one or more preparation criteria are satisfied. A selection and sequence of usage of tool heads is determined for the tooth preparation satisfying the one or more preparation criteria. A result of a simulation of the tooth preparation is output comprising a definition of the selection and sequence of usage.

A computer-implemented method for selecting tool heads for a tooth preparation comprising a removal of tooth material, the method comprising:
- receiving a three-dimensional digital initial tooth model descriptive of one or more current states of one or more teeth to be prepared;
- receiving a three-dimensional digital target tooth model descriptive of one or more target states of the respective one or more teeth to be prepared, wherein the one or more target states are to be achieved starting from the one or more current states by preparing the one or more teeth to be prepared comprising the removal of the tooth material from the respective teeth;
- receiving definitions of tool heads of a plurality of tool heads of a plurality of tool kits defining features of the tool heads of the plurality of tool heads;
- checking, using the defined features of the tool heads of the plurality of tool heads, for different combinations and sequences of usage of the tool heads of the plurality of tool heads, whether one or more preparation criteria are satisfied, the one or more preparation criteria comprising one or more first criteria for a preparation time, the features of the tool heads of the plurality of tool heads being related to approximated preparation times resulting from a usage of the respective tool heads, the checking comprising a checking of the one or more first criteria using the defined features of the tool heads of the plurality of tool heads;
- determining a selection of tool heads from the plurality of tool heads and a sequence of usage of the tool heads of the selection for the tooth preparation satisfying the one or more preparation criteria, wherein the determining comprises executing a simulation of the tooth preparation using the tool heads of the selection according to the sequence of usage of the tool heads of the selection, the simulation being executed using the defined features of the respective tool heads of the selection;
- outputting a result of the simulation comprising a definition of the selection of tool heads and the sequence of usage of the tool heads of the selection.
