Abstract

INTRODUCTION: Computer simulations are stimulating increased attention in dentistry. Augmented reality superimposes a virtual scenario over an existing reality and allows interaction with it. Virtual reality (VR) simulates a fully immersive situation permitting the user to experience the full environment in real time. Haptic technology provides tactile and realistic force feedback for the user to experience the immersive situation as if they were really there. Preclinical training is important to gain familiarity with difficult surgical techniques and to implement interpersonal skills. Developing a valid assessment of surgical simulation is challenging. This paper wants to present a newly realized VR simulation in endodontic microsurgery through the developmental digital workflow, the demonstration of a haptic VR scenario and student self-assessment and self-reflection feedback. METHODS: The volumes were exported in a stereolithography format to prepare and optimize in terms of shape and shade for the VR simulation. The graphics and touchable haptic solid were created using Virteasy Editor, which allows the transformation of 3D surfaces into graphical and volumetric haptic solids depending on their material (enamel, dentine, pulp and bone). Users were asked to execute the osteotomy and root-resection preparation. The assessment criteria were determined, and the feedback statements were created by a questionnaire with fixed answers. Objective and qualitative criteria for assessing the preparation were obtained from the literature. RESULTS: This study provides proof that it is possible to provide reliable and clinically relevant qualitative feedback with a VR simulator. CONCLUSION: VR simulation offers an innovative approach with all the benefits of clinical experience. It permits you to save your own progress and review the assessment at any time.

Summary

Computer simulations are stimulating increased attention in dentistry.

Why This Matters for Hirudotherapy

This validation study describes the development of a virtual reality simulation for endodontic microsurgery training, including osteotomy and root-resection preparation, using haptic technology for tactile feedback and stereolithography-based 3D modeling of dental tissues. The system provided reliable qualitative feedback assessed through student self-assessment questionnaires, demonstrating proof of concept for clinically relevant VR-based surgical training. For ASH's domain, there is no defensible relevance—this study concerns dental surgical education technology with no connection to leeches, hirudotherapy, anticoagulation, wound healing, or any component of the leech secretome. This article has no discernible link to hirudotherapy or ASH's domain in any form.
