Abstract: Dental prosthesis support apparatus includes a plurality of dental implants having self-tapping threads on a lower portion thereof for seating in a jawbone and an upper portion for enabling engagement therewith. An armature is provided having sufficient flexibility to be aligned with the jawbone and engaged along the upper portions of each of the plurality of dental implants seated in the jawbone. The armature is formed from a material enabling subsequent rigidization. The method includes installing a plurality of dental implants into a jawbone in a spaced apart relationship and thereafter removably disposing an armature onto each of the plurality of dental implants and aligning the armature with the jawbone. The armature is removed and rigidized to the jawbone alignment and thereafter affixed onto each of the implants.

Abstract: A process for recovery of fluorocompound gas from an effluent gas stream containing the fluorocompound gas and other gas components, in which at least one of the other gas components is removed, e.g., by oxidation or contacting of the effluent stream with a dry material such as an adsorbent or scrubber medium, to yield a first effluent gas mixture containing the fluorocompound gas. The fluorocompound gas is removed from the first effluent gas mixture and recovered as a concentrated fluorocompound gas, by a process such as cryogenic processing, membrane separation, and/or adsorption.
