MULTIPLE LAYERED DENTURE BLOCK AND/OR DISK

This invention designs and builds multiple layers (two layers or more) of millable dental blocks or disks for milling of various dental devices, specifically denture base blocks or disks of denture base material, where milled teeth cavities to receive artificial denture tooth materials to form final dental devices, such as partial and full dentures. This invention also designs and builds multiple layers (two layers or more) of millable denture base or denture blocks or disks comprised of denture base or/and denture tooth materials to form final dental devices, such as partial and full dentures. A method for manufacturing a layered denture is provided. The invention provides a multiple layered denture base block (or disk) for milling a denture base. The invention also provides a multiple layered denture block (or disk) for milling a denture. Highly shape adjustable or shape memory polymer layer(s) may be used in these multiple layered forms. Different layer of material has different mechanical and physical properties to meet different need, which provide added benefits to the patients, dental professional and dental laboratory.
