This application is a continuation application of U.S. patent application Ser. No. 14/641,926, filed Mar. 9, 2015, now U.S. Pat. No. 9,536,020, which is a continuation of U.S. patent application Ser. No. 13/241,090, now U.S. Pat. No. 9,011,149, filed Sep. 22, 2011, which is a continuation of U.S. patent application Ser. No. 11/933,350, now U.S. Pat. No. 8,047,846, filed Oct. 31, 2007, which is a continuation application of U.S. patent application Ser. No. 11/013,154, now U.S. Pat. No. 7,309,230, filed Dec. 14, 2004, the entire content of each of which is herein incorporated by reference.
The present invention is also related to commonly assigned U.S. patent application Ser. No. 11/013,152, now U.S. Pat. No. 7,922,490, titled “Base for physical dental arch model” by Huafeng Wen, filed Dec. 14, 2004, commonly assigned U.S. patent application Ser. No. 11/012,924, titled “Accurately producing a base for physical dental arch model” by Huafeng Wen, filed Dec. 14, 2004, commonly assigned U.S. patent application Ser. No. 11/013,145, now U.S. Pat. No. 8,636,513, titled “Fabricating a base compatible with physical dental tooth models” by Huafeng Wen, filed Dec. 14, 2004, commonly assigned U.S. patent application Ser. No. 11/013,156, titled “Producing non-interfering tooth models on a base” by Huafeng Wen, filed Dec. 14, 2004, commonly assigned U.S. patent application Ser. No. 11/013,160, now U.S. Pat. No. 7,435,084, titled “System and methods for casting physical tooth model” by Huafeng Wen, filed Dec. 14, 2004, commonly assigned U.S. patent application Ser. No. 11/013,159, titled “Producing a base for accurately receiving dental tooth models” by Huafeng Wen, and filed Dec. 14, 2004, commonly assigned U.S. patent application Ser. No. 11/013,157, titled “Producing accurate base for dental arch model” by Huafeng Wen, filed Dec. 14, 2004.
The intervals of the grid 1900 along x and y direction, shown in FIG. 19, are defined in accordance with the precision requirement. The grid nodes define start and end points for the lines 1720. The grid nodes are indexed. The segment width (i.e. the buffer width) is calculated for each pair of indexed grid nodes at the two opposite rectangular faces o the bounding box 1800. The buffer widths can be resealed and stored for example in 8 bit or 16 bit values.
FIGS. 13(a) and 13(b) show detailed perspective views how two tooth models having the pin configurations shown in FIG. 12 can avoid interfering with each other. FIG. 13(a) shows the front perspective view of two tooth models 1310 and 1320 each of which is respectively affixed pins 1315 and 1325. The pins 1315 and pins 1325 are configured to have different lengths so that the pins do not run into each other when they are inserted into a base (not shown in FIG. 13(a) for clarity). The avoidance of interference between the tooth models 1310 and 1320 is also illustrated in a perspective bottom view in FIG. 13(b).
1. A method for determining and preventing interference between two or more tooth models to be mounted to a dental arch model, the method comprising:
receiving a digital representation of a dental arch model, wherein the digital representation of the dental arch model comprises one or more receiving features;
receiving digital representations of two or more tooth models, wherein each of the digital representations of two or more tooth models comprises one or more registration features that interface with the one or more receiving features;
digitally mounting the digital representations of the two or more tooth models to the digital representation of the dental arch model in a first configuration;
determining an interference between the digital representations of two or more tooth models when mounted to the digital representation of the dental arch model in the first configuration; and
modifying the first configuration to a second different configuration so as to prevent interference between the digital representations of the two or more tooth models when mounted to the digital representation of the dental arch model by modifying at least one of the one or more registration features of at least one of the digital representations of the two or more tooth models.
2. The method of claim 1, wherein the digital representations comprise meshes representing surfaces of a physical dental arch model and two or more physical tooth models.
5. The method of claim 1, wherein modifying the first configuration to the second different configuration comprises adjusting at least one of a position or an orientation of at least one of the digital representations of the two or more digital tooth models when mounted to the digital representation of the dental arch model.
6. The method of claim 1, wherein modifying the first configuration to the second different configuration comprises modifying at least one of the one or more registration features of at least one of the digital representations of two or more digital tooth models.
7. The method of claim 1, wherein modifying the first configuration to the second different configuration comprises modifying at least one of the one or more receiving features of the digital representation of the dental arch model.
8. The method of claim 1, further comprising outputting data for fabricating two or more physical tooth models having the one or more registration features.
11. The method of claim 1, wherein the one or more registration features interface with the one or more receiving features to constrain each of the digital representations of two or more tooth models to a respective predetermined position and orientation on the digital representation of the dental arch model.
