A novel framework to eliminate the effects of casting distortion when fabricating a fixed, detachable screw-retained prosthesis.

The ideal fixed, detachable framework sits passively on the implants and does not introduce any stress. Several techniques in the literature compensate for an ill-fitting framework. These techniques require extra visits, chairtime, and laboratory time and only mitigate the stress; the stress is not eliminated.

Effect of evaporation and mixing technique on die spacer thickness: a preliminary study.

Statement Of Problem: Casting relief is required for proper seating of castings to allow for luting agent thickness. The application of die spacer to the die is the most common method of obtaining casting relief. Die spacer film thicknesses that are outside the ideal range of 25 to 40 microm can cause clinical problems.

An injection technique for generating direct resin post and core patterns.

An injection technique can be used to rapidly generate direct post and core patterns with autopolymerizing acrylic resin. The technique uses an autopolymerizing acrylic resin, a serrated plastic pin, and a syringe with a disposable needle tube and plug to inject acrylic resin into the root canal. The technique is simple, accurate, and faster than the bead-brush technique and eliminates some of its shortcomings.
