Endodontic Training System with Real-Time File Position Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dentists require effective training in endodontic treatment techniques involving rotary files, as the safe use of these instruments is highly dependent on clinical case, operating conditions, and the dentist's training, but existing methods lack a standardized approach for assessing technique correctness.
Innovation Solution
An endodontic system comprising a handpiece with a measurement unit and a computation and display unit that measures and displays graphs representing the evolution of the endodontic instrument's position in the root canal, allowing comparison with reference graphs to assess technique implementation, using a tablet computer for real-time or post-treatment analysis.

Engineering Contradiction Analysis
1Productivity
If rotary files with nickel-titanium are used for endodontic treatment, then the root canal can be shaped and cleaned efficiently following the original canal path, but the safe use of these instruments becomes highly dependent on dentist training and operating conditions
Solution Approach 1:
The system provides real-time feedback to the dentist through a display unit that shows the position, depth, and orientation of the rotary file during endodontic treatment. Sensors detect the file's location relative to the root canal apex and provide continuous monitoring, allowing the dentist to adjust movements to maintain safe operating parameters and prevent instrument complications.
Solution Approach 2:
The patent replaces manual mechanical judgment with electronic sensing and digital display systems. Instead of relying solely on the dentist's tactile feedback and experience, the system uses sensors to detect file position, depth, and orientation, converting these mechanical parameters into visual information that guides safe instrument operation.
2Measurement precision
If standardized assessment methods are implemented for dentist training, then technique correctness can be evaluated objectively, but the complexity of the training system increases
Solution Approach 1:
The system creates a digital copy or representation of the actual file position and movement patterns during treatment. By displaying graphical representations of the file's location, depth, and orientation, the system provides an accurate model that can be used for training assessment without requiring complex physical measurement apparatus.
Solution Approach 2:
The system monitors and displays multiple parameters simultaneously (file position, depth, orientation, speed) to provide comprehensive assessment criteria. By converting physical movements into measurable digital parameters, the system enables objective evaluation of technique correctness while maintaining manageable system complexity through software-based processing.

AI summary
The system according to the invention comprises: a handpiece, to which an endodontic instrument can be connected that is intended to be inserted into a root canal, a measurement unit for measuring a magnitude related to the position of the endodontic instrument in the root canal and a computation and display unit for displaying a graph representing the evolution of the magnitude measured by the measurement unit during an endodontic treatment with the endodontic instrument. The method according to the invention comprises the following steps: displaying, by means of a computation and display unit, a graph representing the evolution of a magnitude measured during a root canal treatment performed by the dentist, the magnitude being related to the position of an endodontic instrument in the root canal, and providing a reference graph representing a predetermined endodontic treatment technique to allow a comparison to be made between the graph representing the evolution of the measured magnitude and the reference graph.
