Abstract:
A method of filing an endodontically prepared root canal includes the steps of applying filler material to a distal portion of an elongated shaft formed of heat conducting material, inserting the proximal portion of the shaft having the filler material thereon into the root canal, heating the shaft to decrease the surface tension of the filler material and removing the shaft leaving the filler material in the root canal. An obturator system for practicing the method of filling an endodontically prepared root canal employs an elongated heat conductible shaft having proximal and distal portions with filler material on the distal portion, the distal portion of the shaft with the filler material thereon being insertable into a tooth root canal and a heat source serving to selectably heat the shaft allowing it to be removed while leaving the filler material in the root canal.
Abstract:
A highly flexible instrument particularly useful in medical applications is elongated and formed of a plurality of flexible metallic strands, at least one strand being spirally wound and having a scraping edge thereon.

Abstract:
A high speed drill bit is formed of a longitudinal body designed to rotate about a longitudinal axis. Each flute has a leading edge with a positive rake angle and a trailing edge with a neutral or negative rake angle. The bit cutting face is formed by surfaces and cutting edges that are asymmetrical with respect to each other.
Abstract:
A combined storage container and installation device for a dental post having an elongated distal end and a proximal head. The device includes an elongated container having a top opening, a cap has a recess therein to hold the proximal head in the recess while allowing fluid to pass into and through the recess. The cap is received and held in the open top of the container. By holding and manipulating the cap, the dental post may be removed from the container and installed under sterilized conditions.
Abstract:
An attachment for pivotally supporting a denture in the mouth of the user in which the user has at least two spaced apart dental posts implanted therein, such posts being in the front of and one to either side of the front center of the mouth of the user, the attachment including an anchor member semi-permanently attached to the anchor posts and having a bar portion extending between the spaced apart dental posts. A denture member which conforms generally to the contour of the anchor member is engagable in proximity with the anchor member bar portion. The denture member is cast within a denture having simulated gum portions and teeth portions. The denture member has an arm for removably and pivotally interlocking the denture member with the anchor member bar portion when a denture having the denture member formed therein is in a usable position within the mouth of the user. Pivotation limiting trunnions are formed as a part of the anchor member. The trunnions serve to limit the angle of pivotation of the denture member relative to the anchor member.
