“…Numerous empirical and experimental studies have been conducted on providing realistic haptic feedback using VR dental simulators including [3,4,5,12,13,14,1]. Studies have evaluated surgical performance and skill acquisition during training and shown that major differences exist between experts and novices in force/torque magnitudes at the hand/tool interface [7,11].…”

With the minute margins of error in endodontic surgery, training in manual dexterity and proper instrument handling are crucial components in the dental curriculum. Important parameters include tool path, tool angulation, and force applied. In this work, we focus on training of correct application of force. This is particularly challenging since the amounts of force used are on the order of tenths of Newtons, requiring a highly refined tactile sense and incorrect force can cause irreversible damage. Too great a force can cause overdrilling or in extreme cases perforation of the tooth. Too small a force can cause thermal irritation possibly resulting in tissue necrosis. Despite the importance of correct use of force, this is the dimension on which students receive the least tutorial feedback since force information is typically not available in traditional training settings. In this paper, we present an approach to using haptic feedback as a means to convey formative feedback on the correct application of force. Feedback is conveyed to the student graphically and the correct amount of force to apply is trained haptically. The simulator is rewound and the student is asked to redo the stage where the error occurred. Preliminary evaluation against a control group of students who received only feedback concerning outcome shows the feedback mechanism to be effective.

“…With respect to the utilised devices, the Phantom haptic device, with 6 DOF for tracking and 3 DOF for force feedback, was found to be the prevailing choice to control rotating instruments for coronary opening [2] [3], to simulate both the usage of the odontological mirror [4] and periodontical procedures [5] [6] . In the specific area of endodontics, only work on file deformation and tooth pulp behaviour analysis was found.…”

This paper describes a virtual reality simulator for training endodontics operations using manual files. The simulator consists of a custom 4DOF haptic device for tracking and force feedback. The built device can simulate the kinematic behaviour of the files during endodontic surgery. During the simulation, the movements the user does with the manual files are tracked and at the end are displayed by a custom-made visualization tool. This tool shows the forces applied during the procedures, the direction and the amplitude of the movements and the final result of the tooth preparation. Preliminary tests showed that the level of realism of the simulator is satisfactory and the visualization tool allows for obtaining relevant data for a qualitative analysis of the procedures performed on the tooth.

“…The user should feel force and torque when he/she pushes the tongue and moves the probe inside the periodontal pocket. Several approaches were reported on dental simulation involving haptics [14], [15], [16], [17], [18], [19]. Only a few of them provide deformation simulation of oral organs.…”

There are two main challenges in simulating bi-manual dental operations with six-degrees-of-freedom (6-DoF) haptic rendering. One is to simulate large deformation and force response of a tongue under multi-region contacts with a dental mirror, and the other is to simulate the force response when a dental probe inserts into a narrow periodontal pocket, which leads to simultaneous contacts of different types between the probe and both rigid and deformable objects (i.e., a rigid tooth and its surrounding deformable gingiva), which we call hybrid contacts, as well as frequent contact switches. In this paper, we address both challenges. We first introduce a novel method for modeling deformation based on a sphere-tree representation of deformable objects. A configuration-based constrained optimization method is utilized for determining the six-dimensional configuration of the graphic tool and the contact force/torque. This approach conducts collision detection, deformation computation, and tool configuration optimization very efficiently, avoids inter-penetration, and maintains stability of haptic display without using virtual coupling. To simulate the force response due to fine manipulation of the probe inside a narrow periodontal pocket, we propose an efficient method to simulate the local deformation of the gingiva and stable haptic feedback under frequent contact switches. Simulations on typical dental operations were carried out to validate the efficiency and stability of our approach.
