Virtual aids and students' performance with haptic simulation in implantology.

Objetives: This study aims to validate that haptic simulator assistance could improve drilling ability in implantology and that the repetition of training session could highlight a learning curve.

Methods: This work was carried out with 88 first-year dental students. After randomization, students were divided into two groups. Group 1 was assigned to prepare an implant site for a left first mandibular molar (36) on haptic simulator with assistance provided by simulator. Group 2 had to perform the same exercise without assistance. Whatever the group, the maximum time for each reparation was restricted to 5 min. An interval of 1 week was done between each session. For each test, different objective parameters provided by the simulator were recorded and analyzed.

Results: This study showed that the presence of virtual aids led to quickly obtain better results, and the training led to gradually acquire sufficient competence to do without virtual aids.

Conclusion: By associating virtual assistance and repetition, the student will acquire more quickly the skills allowing to carry out his clinical gestures in real conditions.
