The aim of the present study was to develop a Virtual Learning Object (VLO) on impression materials, with emphasis on alginate, and to evaluate the influence of its use on the theoretical learning and clinical skills of dental students, as well as on the physical properties and material mechanics. Sixty-four students received a theoretical lecture on alginate and were later divided into 2 groups, Control (n=30) and VLO (n=34). The VLO group had access to the educational tool composed of theoretical content and simulation of alginate mixing, and their ability was evaluated. All participants performed a pre-test after the theoretical class, as well as tests of ability to handle the material, which was subjected to a compressive strength test and detail reproduction. A posttest evaluation was performed after fifteen days. The results of the groups were compared by the t test, logistic regression model and significant variables were included in the multiple regression model. All analyzes were conducted with a significance of 5%. In the VLO simulation, 75% of the users obtained the maximum score and the results of the theoretical assessments did not indicate a statistical difference between the groups. The use of VLO is related to greater clinical skill, with 3.76 more chances of correct incorporation of the powder. In the compressive strength test, the mean of the groups was higher than that recommended by the standard, VLO 0.86±0.03 and Control 1.09±0.04. The developed tool has a positive influence on the clinical ability and mechanical property of the material studied, constituting itself as a promising strategy of virtual learning.
