Preceramic and postceramic solder joints.
TLDR
This investigation evaluated preceramic and postceramic soldering procedures and found the strongest joints were achieved by using wider gaps and the oven soldering technique.Abstract:
This investigation evaluated preceramic and postceramic soldering procedures. Three gap spaces and two soldering methods were evaluated. Wider gaps produced stronger joints. The strongest joints were achieved by using wider gaps and the oven soldering technique. Very wide gaps (0.76 mm.) are not recommended because of possible distortion through excessive solder shrinkage. However, in practice, many solder joints exceed the 0.31 mm. recommended minimum; these joints will not show decreased strength.read more

Distortion of Three-Unit Implant Frameworks During Casting, Soldering, and Simulated Porcelain Firings
TL;DR: Assessment of distortion inherent in casting, soldering, and simulated porcelain firings of screw-retained, implant-supported three-unit fixed partial dentures found Soldering did not improve the casting misfit of a three- unit implant-ret retained FPD model.

An investigation of tensile strength of dental solder joints
TL;DR: It was concluded that there was a significant increase in strength for the Type III gold as the gap distance was increased, and the postsolder joints were statistically stronger than the presolder joints.

Accuracy of one-piece castings, preceramic and postceramic soldering.
TL;DR: An investigation was conducted to evaluate the relative accuracy of one-piece castings of FPDs of three, four, and five units with those assembled by preceramic soldering and postceramic Soldering.

Distortion in dental soldering as affected by gap distance
Leon M. Willis,Jack I. Nicholls +1 more
TL;DR: In identifying the criteria which influence soldering distortion, the results of this study indicate the following: linear distortion identified at the investment phase is due to setting expansion of the plaster and soldering investment, and linear distortion occurs because of the contraction of the solder.

Warpage produced by soldering with dental solders and gold alloys
TL;DR: In this paper, it was shown that the more precise the fit of the parts to be soldered, the less they will be distorted, whether the joints considered are of wires or of bars.
