Abstract

The invention discloses a multi-dimensional artificial operation force measuring device for root canal preparation, comprising a dental handpiece for preparing root canal of simulated teeth. The simulated tooth is mounted on a six-dimensional force measuring device for measuring the six-dimensional force information of the simulated tooth during the root canal preparation process. The dental handpiece is provided with a three-dimensional force measuring device for measuring three-dimensional force information that the operator applies to the handpiece during the root canal preparation process.The three-dimensional force measuring device is composed of a central force ball and two three-dimensional force measuring units. The six-dimensional force measuring device of the tooth body is composed of a bottom plate, a six-dimensional force sensor, a U-shaped tooth fixing groove, and a U-shaped tooth baffle. The multi-dimensional artificial operation force measuring device for root canal preparation can obtain multi-dimensional mechanical information applied by the operator's hand and multiple dimensional force information of the simulated tooth in real time, thereby providing direct analysis data for analyzing the influence of the artificial operating force on the root canal formation.

Description

technical field

[0001] The invention relates to the technical field of multidimensional force measurement, in particular to a multidimensional human-operated force measurement device for root canal preparation. Background technique

[0002] Modern root canal therapy believes that good root canal preparation is the premise of tight root canal filling and the key to the success of tooth root canal therapy. The main purpose of root canal preparation is to use mechanical removal of infected pulp while forming a root canal shape suitable for filling, and it is required to maintain the original anatomical direction of the root canal as much as possible. Because of its elasticity and memory, machine-used nickel-titanium instruments can effectively and continuously taper the relatively small and curved root canals, which can better maintain the original shape, reduce deviation, and form a better root canal shaping effect.

[0003] The research found that the shaping effect of the r...
