“…Rubin et al 6 built a 3D laryngeal model from MRIs and CTs of a cadaver larynx. Their 3D structure was made up of multiple units, with each unit being an individual muscle, cartilage, or ligament.…”

“…It is based on more than 1 cadaver/patient so that it illustrates the variability in human anatomy. This is 1 key advantage of our model over the model of Rubin et al 6 Furthermore, our model also includes special cases and clinical vignettes customized to the clinical scenarios that may be experienced by students in practice. It is also Web based and accessible by any student on the World Wide Web.…”

“…This data is similar in resolution to that obtainable through modest MRI capabilities available currently that can achieve a resolution of the order of 1 mm. 31,35,46 The geometric models were further enriched to incorporate VF histology.

“…This allows for a broader range of geometric abstraction level and consideration of the interaction with the tissue’s biomechanical properties. Although MRI of human VFs is able to differentiate hard cartilages in the larynx from soft tissue, 12,13,31,32 we are unaware of its capability to recognize and distinguish the underlying tissue histology. Therefore, an assumed cover thickness is used to define an identical body-cover partition in all the models.…”

Summary The present article aimed at constructing a canonical geometry of the human vocal fold (VF) from subject-specific image slice data. A computer-aided design approach automated the model construction. A subject-specific geometry available in literature, three abstractions (which successively diminished in geometric detail) derived from it, and a widely used quasi two-dimensional VF model geometry were used to create computational models. The first three natural frequencies of the models were used to characterize their mechanical response. These frequencies were determined for a representative range of tissue biomechanical properties, accounting for underlying VF histology. Compared with the subject-specific geometry model (baseline), a higher degree of abstraction was found to always correspond to a larger deviation in model frequency (up to 50% in the relevant range of tissue biomechanical properties). The model we deemed canonical was optimally abstracted, in that it significantly simplified the VF geometry compared with the baseline geometry but can be recalibrated in a consistent manner to match the baseline response. Models providing only a marginally higher degree of abstraction were found to have significant deviation in predicted frequency response. The quasi two-dimensional model presented an extreme situation: it could not be recalibrated for its frequency response to match the subject-specific model. This deficiency was attributed to complex support conditions at anterior-posterior extremities of the VFs, accentuated by further issues introduced through the tissue biomechanical properties. In creating canonical models by leveraging advances in clinical imaging techniques, the automated design procedure makes VF modeling based on subject-specific geometry more realizable.

3D Technology Development and Dental Education: What Topics Are Best Suited for 3D Learning Resources?

2020

The aim of this study is to identify topics (knowledge and skills) from the dental curricula that would benefit from having a 3D learning resource using an exploratory sequential design method. The first phase targeted stakeholders from a Scottish dental school. Seven focus groups and three interviews disclosed 97 suitable topics for 3D technology development. These results were used to construct a survey that was sent to final year dental students, newly dental graduates and academics from three Scottish universities. The survey asked participants to rank each item based on the perceived benefit that a 3D learning resource would have for dental education. Results revealed that detailed anatomy of the temporomandibular joint, dental anaesthesiology, dental clinical skills techniques, dental occlusion and mandibular functioning were top priorities. Gender differences only appeared in relation to ‘Extraction techniques: movements and force’ (p < 0.05), this topic was considered to be more beneficial by females than by males. No statistical difference was found when comparing results of graduates with undergraduates. These results serve as a starting point when developing a new 3D technology tool for dental education, considering users demands and perceived needs has the potential to benefit dental students and dental education directly.
