Methods are provided for computer-based planning of a dental restorative procedure of a patient having a craniooral space and/or of at least one dental component for the dental restorative procedure. Certain methods include determining a first spatial position of a first boundary surface, in the craniooral space, of a first dental unit of a dental restoration determining a second spatial position of a second boundary surface, in the craniooral space remote the first boundary surface, of a second dental unit of the dental restoration and determining a third spatial position of at least a portion of the at least one dental component relative at least one of the first and second spatial positions.
