DIGITALLY MODELING THE DEFORMATION OF GINGIVAL TISSUE DURING ORTHODONTIC TREATMENT |
| 摘要 |
A computer obtains a digital model of a patient's dentition, including a dental model representing the patient's teeth at a set of initial positions, and a gingival model representing gum tissue surrounding the teeth. The computer then derives (540)(542)(544)(546)(548) from the digital model an expected deformation of the gum tissue as the teeth move from the initial positions to another set of positions.
