A composite pipe segment is formed to include tapered in wall thickness ends that are each defined by opposed frustoconical surfaces conformed for self centering receipt and intimate bonding contact within an annular space between corresponding surfaces of a coaxially nested set of metal end pieces. The distal peripheries of the nested end pieces are then welded to each other and the sandwiched and bonded portions are radially pinned. The composite segment may include imbedded conductive leads and the axial end portions of the end pieces are shaped to form a threaded joint with the next pipe assembly that includes a contact ring in one pipe assembly pierced by a pointed contact in the other to connect the corresponding leads across the joint.

A dental tray is provided using a molded plastic. One form of tray includes buccal and lingual walls defining a series of recesses or indentations on opposed wall faces. When in use, a flexible impression support is applied to the walls and is coated with a suitable impression cement which enters the recesses and secures the impression support thereto. After an impression has been taken, the impression support is stripped from the tray and a mold is made therefrom. The use of recesses in the walls facilitates manufacturing of an inexpensive device of plastic using high speed, injection molding techniques.
