Patent ID: 7762811

Claim:
An orthodontics assisting system comprising: a first index member which indicates reference positions of a pre-correction dentition model having a dentition shape before orthodontics; a second index member which indicates reference positions of a post-correction predictive dentition model having a predictive dentition shape after orthodontics; an arranging device for arranging said first and second index members on the pre-correction dentition model and the post-correction predictive dentition model, respectively, to cause said first and second index members to indicate the reference positions, respectively; image data generating means for generating pre-correction dentition image data including first index image data based on said first index member arranged on the pre-correction dentition model and post-correction predictive dentition image data including second index image data based on said second index member arranged on the post-correction predictive dentition model, by imaging the pre-correction dentition model and the post-correction predictive dentition model, respectively, with said first and second index members respectively arranged thereon by said arranging device; screen display means for screen-displaying a pre-correction dentition image and a post-correction predictive dentition image respectively based on the pre-correction dentition image data and the post-correction predictive dentition image data generated by said image data generating means; position adjusting means for adjusting on the basis of the first and second index image data mutual overall display positions of the pre-correction dentition image and the post-correction predictive dentition image which are screen-displayed by said screen display means; and tooth position adjusting means for extracting teeth image data from the pre-correction dentition image data and for adjusting display positions with respect to the post-correction predictive dentition image of teeth images based on the extracted teeth image data, said arranging device including holding means for holding the index members; supporting means which supports said holding means and is mounted model teeth of the pre-correction dentition model and the post-correction predictive dentition model; and a position adjusting mechanism for adjusting the position of said holding means with respect to each of the pre-correction dentition model and the post-correction predictive dentition model.
