Embodiments of the present invention provide a method, system, devices and software which provide customized, clinically relevant designs, e.g. treatment plans/solutions for at least single tooth replacement therapy in real-time as needed to enable immediate confirmation of the validity and execution of patient-specific treatment solutions. A Machine Learning algorithm is used in a method or system for computer implementation of automatic restoration design. The restoration design includes the design of restorative elements such as crowns and abutments. Software is provided for carrying out the methods when executed on a digital processor. Manufacturing of the restorative elements is also included.

Method, system and devices for instant automated design of a customized dental object

A bonded abrasive tool, having a structure permeable to fluid flow, comprises sintered agglomerates of a plurality of abrasive grains and a binding material, the binding material being characterized by a melting temperature between 500 and 1400&#xb0; C., and the sintered agglomerates having a loose packing density of &#x2266;1.6 g/cc and three-dimensional shape; a bond material; and about 35-80 volume % total porosity, including at least 30 volume % interconnected porosity. Methods for making the sintered agglomerates and abrasive tools containing the sintered agglomerates are described.

Porous abrasive articles with agglomerated abrasives

Bonded abrasive tools, having novel porous structures that are permeable to fluid flow, comprise a relatively low volume percentage of abrasive grain and bond, and a relatively low hardness grade, but are characterized by excellent mechanical strength and grinding performance. Methods for making the abrasive tools utilizing agglomerated abrasive grain are described.

Abrasive articles with novel structures and methods for grinding

Organic bonded abrasive tools, having controlled microstructures, comprise a relatively low volume percentage of abrasive grain and a relatively low hardness grade, but are characterized by the excellent mechanical strength and efficient grinding performance of much harder grade, lower porosity tools, especially in versatile grinding processes, such as centerless grinding. A method for centerless grinding with these tools is provided. Methods for making the abrasive tools utilizing agglomerated abrasive grain are described.

A bonded abrasive tool, having a structure permeable to fluid flow, comprises sintered agglomerates of a plurality of abrasive grains and a binding material, the binding material being characterized by a melting temperature between 500 and 1400&#xb0; C., and the sintered agglomerates having a loose packing density of &#x2266;1.6 g/cc and three-dimensional shape; a bond material; and about 35&#x2013;80 volume % total porosity, including at least 30 volume % interconnected porosity. Methods for making the sintered agglomerates and abrasive tools containing the sintered agglomerates are described.

Porous abrasive articles with agglomerated abrasives and method for making the agglomerated abrasives

Grinding of mill rolls is carried out with chatter resistant abrasive grinding wheels having relatively low elastic modulus values and relatively high burst speed values. Grinding operations may be carried out at high efficiency with controlled wheel vibration, thus generating optimum surface quality on the ground mill rolls.
