摘要： The present invention is a method for forming, repairing or restoring a dental restoration which includes the steps of forming a base material of high-fusing temperature metal particles, low fusing temperature metal particles and a volatile binder substantially or entirely of wax; applying the base material to a die; shaping the base material upon said die into the desired configuration of the dental restoration; removing the configured base material from the die; combining particles of activated carbon with investment material to form a combined dental investment material having activated carbon in a concentration above at least 0.005 wt. % of the combined dental investment material; filling the configured base material with the combined dental investment material; heat treating the shaped base material in the investment at temperatures up to 1200.degree. C. to vaporize the volatile binder from the base material for forming a porous structure with a void volume of at least 20%; and filling the porous structure with a filler material to form a finished dental coping.

摘要： A moldable dental composition including high-fusing temperature metal particles and a binder comprising wax preferably in a concentration of above at least twenty percent (20%) of the composition. The high-fusing temperature metal particles should have an irregular nonspherical geometry and a thin cross-sectional average thickness. The moldable dental composition may also contain low fusing temperature metal particles for enhanced wetting of the high fusing metal particles during heat treatment at a heat treatment temperature which will substantially melt the low fusing metal particles. However it is not essential to the subject invention for the composition to contain low fusing metal particles.

摘要： The dental prosthesis of the present invention includes a plurality of flexible metal arm connectors which extend from a common member in forming a bridge or from a common joint in forming a splint. The arm connectors are adapted to be affixed to adjacent retaining members on the abutment teeth to be restored. The arm connectors must be sufficient in length to make reasonable contact with the buccal and lingual surfaces and preferably should contact the occlusal surface as well. The arm connectors may be ring-like in geometry and/or be corrugated for expansion.
