Patent ID: 8832019

Claim:
A computer system for dental implant treatment planning that simulates various error conditions before actual surgery, comprising: 1) a computer hardware system with an operating system, 2) an interactive computer software that is saved to a non-transitory computer readable medium, which generates images and graphics shown on a display of the computer, and performs treatment planning error simulation, wherein: a) a software interface is used to obtain a desired treatment plan of all the implants in a treatment planning case, b) a plan display module is provided to display treatment plan with 2D and 3D views, where (1) the display at least comprises of implants and bone structures, (2) display options comprise of black/white display, color map of the CT Hounsfield Unit values, transparency and 2D slice scrolling, and (3) plan evaluation tools are provided together with the display, c) an error simulation module is provided to perform simulation, comprising i. an error source definition module to specify various error sources that exist in both the treatment planning, surgical guide manufacturing and actual treatment and can cause the actual outcome of a treatment to be off the treatment plan, ii. said error sources are translated into five components of an implant positional deviation, iii. a statistic distribution is assigned to the error sources, iv. a plan deviation module to generate variations of said treatment plan by continuously applying different deviations to the implant parameters, and v. a simulation control module to control the said deviation module with “Start”, “Pause” and “Resume” actions, and send its outputs to said plan display module, whereby the computer system can continuously modify and update treatment plans with the possible deviations so that doctors can visually evaluate and adjust the treatment plans for the best implant positions and orientations even before the treatment is performed, and thus lower the risk of implant failures.
