Lessons learnt and lessons missed from flight simulation
European Journal of Dental Education, EarlyView., 2023 Abstract This article reviews progress in the development of technologies used in flight simulation and in the training of dentists, drawing out the similarities in training objectives and the limitations of the training devices. It summarises the advances in pilot training with recognised international standards for the construction and acceptance of ...

Dense Representative Tooth Landmark/axis Detection Network on 3D Model [PDF]
arXiv, 2021 Artificial intelligence (AI) technology is increasingly used for digital orthodontics, but one of the challenges is to automatically and accurately detect tooth landmarks and axes. This is partly because of sophisticated geometric definitions of them, and partly due to large variations among individual tooth and across different types of tooth. As such,

Tooth-shaped plasmonic waveguide filters with nanometeric sizes [PDF]
Opt. Lett. 33, 2874-2876 (2008), 2009 A novel nanometeric plasmonic filter in a tooth-shaped Metal-Insulator-Metal waveguide is proposed and demonstrated numerically. An analytic model based on the scattering matrix method is given. The result reveals that the single tooth-shaped filter has a wavelength filtering characteristic and an ultra-compact size in the length of a few hundred ...

Evidence to Suggest That Teeth Act as Human Ornament Displays Signalling Mate Quality [PDF]
, 2012 Ornament displays seen in animals convey information about genetic quality, developmental history and current disease state to both prospective sexual partners and potential rivals. In this context, showing of teeth through smiles etc is a characteristic

Multiple Geminated Supernumerary Premolars: A Rare Case Report
Case Reports in Dentistry, 2015 Supernumerary teeth may be defined as any teeth or tooth substance in excess of the usual configuration of 20 deciduous and 32 permanent teeth. Gemination is defined as an attempt by a single tooth bud to divide, with a resultant formation of either a ...

DArch: Dental Arch Prior-assisted 3D Tooth Instance Segmentation [PDF]
arXiv, 2022 Automatic tooth instance segmentation on 3D dental models is a fundamental task for computer-aided orthodontic treatments. Existing learning-based methods rely heavily on expensive point-wise annotations. To alleviate this problem, we are the first to explore a low-cost annotation way for 3D tooth instance segmentation, i.e., labeling all tooth ...

Molecular genetics of supernumerary tooth formation [PDF]
genesis, 2011 AbstractDespite advances in the knowledge of tooth morphogenesis and differentiation, relatively little is known about the aetiology and molecular mechanisms underlying supernumerary tooth formation. A small number of supernumerary teeth may be a common developmental dental anomaly, while multiple supernumerary teeth usually have a genetic component ...
