Method and system for 3D root canal treatment planning
A three-dimensional computer model of the patient's tooth, including the pulp chamber and root canals, is created by combining at least one grey value image of the tooth and/or surface information about at least part of the intra-orally visible part of the tooth with a statistical, parameterized shape model of each tooth type (upper or lower incisors, canines, pre-molars, molars) as the patient's tooth to be treated. This allows for planning and/or simulation of one or more root canal treatments on the computer model of the patient's tooth and that the dentist or dental specialist is given qualitative and/or quantitative information by the system in order to aid in adequately analyzing the risks related to performing the root canal treatment with the proposed or user-selected endodontic tools.
1. A method for 3D planning of root canal treatments comprising the steps of:
generating and visualizing a 3D model of the tooth to be treated by combining at least one piece of tooth specific digital information with a statistical, parameterized shape model of each tooth type, wherein the 3D model includes the pulp chamber and root canals;
planning and/or simulating the root canal treatment on the generated 3D model of the tooth;
using the planning and/or the simulating of the root canal treatment to create a visualization of gualitative and/or quantitative feedback relative about the effect of the planned/simulated treatment on the 3D model, and
selecting or determining of the best approach to the root canal treatment,
wherein the step of selecting or determining of the best approach to the root canal treatment develops a root canal treatment sequence of treatment steps for infected pulp of the tooth, which treatment steps result in elimination of infection in the infected pulp of the tooth, decontamination of the tooth, and protection of the decontaminated tooth from future microbial invasion.
2. The method of claim 1 , wherein. the tooth type cow rises upper or lower incisors, canines, pre-molars, or molars.
3. The method of claim 1 , wherein the 3D model is obtained from 2D grey value image(s) of patient's tooth and 3D surface information of an intra-orally visible part of patient's tooth.
4. The method according to claim 3 wherein the 2D grey value image(s), 3D surface information and the statistical, parameterized shape model of each tooth type are loaded into a computer.
5. A non-transitory storage medium storing a computer program product which when executed on a computer causes the computer to perform the method of claim 1 .
6. A method for 3D planning of root canal treatments comprising the steps of:
generating and visualizing a 3D model of the tooth to be treated by combining at least one piece of tooth specific digital information with a statistical, parameterized shape model of each tooth type, wherein the 3D model includes the pulp chamber and root canals;
planning and/or simulating the root canal treatment on the generated 3D model of the tooth;
using the planning and/or the simulating of the root canal treatment to create a visualization of qualitative and/or quantitative feedback relative about the effect of the planned/simulated treatment on the 3D model, and
selecting or determining of the best approach to the root canal treatment, wherein,
the step of using the planning and/or the simulating of the root canal treatment to create a visualization of qualitative and/or quantitative feedback relative about the effect of the planned/simulated treatment on the 3D model is based on a simulated root canal treatment and presents information related to risks of the simulated root canal treatment, and
the step of selecting or determining of the best approach to the root canal treatment develops a root canal treatment sequence of treatment steps for infected pulp of the tooth, which treatment steps result in elimination of infection in the infected pulp of the tooth.
