“…For this study, we used the manual dexterity exercises developed by ACTA (Academic Center for Dentistry, Amsterdam, The Netherlands; www.acta.nl) used previously to examine motor skill. 31 The simulator outputs stereo information via two digital multimedia projectors, which operate simultaneously, resulting in the projection of two images superimposed onto the screen through a polarising filter. The screen size is 5″ with a refresh rate of 60 Hz and a resolution of 800 9 600.…”

PurposeOne suggested advantage of human binocular vision is the facilitation of sophisticated motor control behaviours via stereopsis – but little empirical evidence exists to support this suggestion. We examined the functional significance of stereopsis by exploring whether stereopsis is used to perform a highly skilled real‐world motor task essential for the occupational practice of dentistry.MethodsWe used a high fidelity virtual reality simulator to study how dentists’ performance is affected by the removal of horizontal retinal image disparities under direct and indirect (mirror) observation. Thirteen qualified dentists performed a total of four different dental tasks under non‐stereoscopic and stereoscopic vision conditions, with two levels of task complexity (direct and indirect observation) using a virtual reality dental simulator.ResultsDepth related errors were significantly higher under non‐stereoscopic viewing but lateral errors did not differ between conditions. Indirect observation led to participants drilling less of the target area compared to direct viewing, but this did not interact with the stereopsis manipulation.ConclusionsThe data confirm that dental practitioners use stereopsis and its presence results in improved dental performance. It remains to be determined whether individuals with stereo‐deficits can compensate adequately. Nevertheless, these findings suggest an important role for stereopsis within at least one occupation and justify the design of simulators with 3D displays.

“…While it is recognised that expert performance is faster than novice performance [10,11], the converse is not necessarily true, i.e. faster performance does not necessarily confer better quality surgery [54,55]. The same applies to simulator-generated metrics; for example, while experts tend to have smoother movements, having smoother movements does not necessarily mean the operator is an expert.…”

Background: Recent evidence indicates that a preoperative warm-up is a potentially useful tool in facilitating performance. But what factors drive such improvements and how should a warm-up be implemented? Methods:In order to address these issues, we adopted a two-pronged approach: (i) we conducted a systematic review of the literature to identify existing studies utilizing preoperative simulation techniques; (ii) we performed task analysis to identify the constituent parts of effective warm-ups. We identified five randomised control trials, four randomised crossover trials and four case series. The majority of these studies reviewed surgical performance following preoperative simulation relative to performance without simulation.Results: Four studies reported outcome measures in real patients and the remainder reported simulated outcome measures. All but one of the studies found that preoperative simulation improves operative outcomes-but this improvement was not found across all measured parameters. Whilst the reviewed studies had a number of methodological issues, the global data indicate that preoperative simulation has substantial potential to improve surgical performance. Analysis of the task characteristics of successful interventions indicated that the majority of these studies employed warm-ups that focused on the visual motor elements of surgery. However, there was no theoretical or empirical basis to inform the design of the intervention in any of these studies. Conclusions:There is an urgent need for a more rigorous approach to the development of Ôwarm-upÕ routines if the potential value of preoperative simulation is to be understood and realised. We propose that such interventions need to be grounded in theory and empirical evidence on human motor performance.

“…After providing sufficient evidence confirming the soundness of the dental trainer, further research should focus on the added educational value derived from the use of the VRE compared to and in addition to contemporary teaching methods, in terms of quality and cost amongst others. A first study on the added value of feedback from the dental trainer (combined with instructional feedback) was published . A major advantage of VRE in education innovation is being connected to a database that collects all information on performance and student behaviours during their learning process.…”
