Abstract
A method and system to evaluate image-guided dental implant treatment plans with error simulation. Error sources contributing to the inaccuracy of implant cases come from impressions, stone models, radiographic guides, CT scan and its image processing, surgical guides, as well as the surgical procedures. They are translated into the deviations between the planned and actual implant positions and orientations. The error simulation is to continuously modify and update treatment plans with the possible deviations so that the treatment plans can be visually evaluated along with other evaluation tools.
Claims6
The method to simulate errors for image-guided dental implant treatment planning system, comprising of the following steps:
- various error sources are identified according to the treatment planning workflow,
- the error sources are modeled, translated and combined into the possible deviations of implant positions and orientations of a planning case,
- a series of possible deviations are generated,
- the treatment plan is modified by each possible deviation, and
- for each possible deviation, graphical feedbacks are given by updating the display of implants along with patient CT scan slice data or 3D models.
