Dental composite material and process |
摘要 |
A composite suitable for use as dental composite is provided by a glass material having a softening range of at least 10 DEG C. and having a particle size of less than 250 mesh to provide a precursor mix. The precursor mix is mixed with a fugitive pore forming material and a binder to form a pressable mix. The pressable mix is pressed at a pressure in excess of 5,000 pounds per square inch to form a sinterable mix. The sinterable mix is sintered for a period of time sufficient to remove said fugitive pore forming material and to form a sintered mass for crushing to form particles of less than 250 micrometers in size to be incorporated into a dental composite. |
