Only in the clinic problem solving, pathology and preparation design are integrated.Only in the clinic problem solving, pathology and preparation design are integrated.

4 Why change? Educational reasonsEducational reasons - improve integration theory and practice - improve integration theory and practice - process and outcome evaluation - process and outcome evaluation - incorporation of problem solving in preclinical training - incorporation of problem solving in preclinical training - practice in realistic context closing the gap to the clinic - practice in realistic context closing the gap to the clinic

5 Why change? Practical reasonsPractical reasons - reduction of maintenance costs - reduction of maintenance costs - no waste of materials - no waste of materials - no water problems ( legionella) - no water problems ( legionella) - unlimited availability of practice material - unlimited availability of practice material

16 Purpose of the study To investigate if students without any dental experience practicing at the Simodont will develop skills transferable to reality at a similar level as students practicing in the traditional preclinical settingTo investigate if students without any dental experience practicing at the Simodont will develop skills transferable to reality at a similar level as students practicing in the traditional preclinical setting

17 Experiment S (n=10) P (n=10) C (n=8) Day 1 test + practice (2x30) test Day 2 practice (3x30) Day 3 test + practice (2x30) test Day 4 practice (2x30) + test test

19 Design Students practice after an initial test their manual dexterity for handling a dental bur either on the Simodont or with a real bur on resin plates.Students practice after an initial test their manual dexterity for handling a dental bur either on the Simodont or with a real bur on resin plates. Thereafter they perform a similar test on plastic blocksThereafter they perform a similar test on plastic blocks

36 Conclusions Practicing resulted in a better performance than without practicing.Practicing resulted in a better performance than without practicing. Skills transfer from the Simodont to reality was equal as from reality to reality.Skills transfer from the Simodont to reality was equal as from reality to reality. Practicing after the second test did not show any improvement probably due to reduced concentration and fatiguePracticing after the second test did not show any improvement probably due to reduced concentration and fatigue
