Background/purpose: En masse retraction was still controversy in orthodontics.The aim of this study was to investigate the effect of force directions created by different miniscrew positions and lever arm heights Baby Rattle on maxillary central incisor movement using Finite Element (FE) simulation and a Typodont model.Materials and methods: A typo
The present paper was created with Tram the aim of investigating a rapidly spreading phenomenon, such as crowdfunding, starting with a general overview of the nature of the mechanism, to then focus on the growing importance in the sports sector.Crowdfunding is a collective funding mechanism that arises fundamentally from the need for small projects
The nanoindentation test is frequently used as an alternate method to obtain the mechanical properties of ductile materials.However, due to the lack of information about the effects of the sample and indenter physical configurations, the accuracy of the extracted material properties in nanoindentation tests requires further evaluation that has been
Partial dampness is the initial stage in the bushing damp process,so the effective diagnosis of partial dampness can avoid the further development of the damp.The partial damp diagnosis method of bushing based on the Shorts frequency domain spectroscopy (FDS) is proposed in this paper.Firstly,oil-paper insulation samples with different moisture con
