When ceramic structures are used in the mouth, there is often a risk of wear between teeth and the ceramic part. Scientists from Boston’s University School of Dental Medicine have been researching this effect when different dental ceramic systems are used. Disc shaped specimens were held in resin and they used their TA.XTplus Texture Analyser along with a multiple sample vertical friction wear device to perform wear simulation. No differences were found in the linear and volumetric reduction of enamel cusps abraded against enamel disks or ceramic specimens. Read more
Meanwhile, Mars Inc. have been fabricating animal jaws. They have recently released a patent, entitled ‘Animal dentistry apparatus and methods’. Chewable products are often used to improve the oral hygiene of animals as the chewing action can help to remove plaque. It is useful to understand the mechanical properties of these products as they can affect their performance in cleaning teeth; existing mechanical measurement techniques involve their compression with cylindrical probes. This patent addresses the shortcomings of in-vivo measurements with existing test methods for chewable products. They used their TA.HDplus Texture Analyser to perform tests with a mechanical jaw assembly. Read more
Over in Hangzhou, researchers from Zhejiang Gongshang University have been investigating the locking up of food between posterior teeth and its influence on chewing efficiency. Food particles are intra-orally locked up between antagonistic posterior teeth during each chewing cycle, and this can affect the selection of particles for subsequent breakage, hence also affecting chewing efficiency. The two aims of this study were to determine the extent of locking up and to examine the relationship between locking up and chewing efficiency. The researchers used their TA.XTplus Texture Analyser to perform penetration tests on sheet bolus samples. Relationships between locking up and chewing efficiency were successfully found. Read more
Scientists from Zhejiang University of Technology have been researching the fabrication and evaluation of dental fillers using customised moulds via 3D printing technology. In view of the high incidence and long-term treatment of dental caries, personalised dental fillers with long therapeutic action have broad application prospects in the dental clinic. The objective of this study was to fabricate and evaluate novel dental fillers using state-of-the-art 3D printing technology. To mimic the support from peripheral tooth tissue, the compression behaviour of the optimal dental filler was determined with customised compression molds designed according to the printed mold, using their TA.XTplus Texture Analyser. The study confirmed that 3D printing was successful in designing and fabricating personalised dental fillers with high mechanical strength and “on-demand” drug release characteristics. Read more
