Abstract
A dental soldering technique called stand soldering method was studied in this paper by determining the displacement of three-unit fixed partial dentures.
The number of times to pre-heat the stand, the height of the pillar of the stand and the thermal expansion coefficient of the stand were investigated as possible main factors causing the displacement.
The conclusions obtained were as follows:
Pre-heating of the soldering stand should be done at least once. The pillars of the soldering stand should be designed as short as possible. The material of the soldering stand should be identical to that of the denture in terms of the thermal expansion coefficient.
