title: Improving the cementation of complete cast crowns: a comparison of static and dynamic seating methods.
abstract: This study measured the effect of static and dynamic forces, during cementation, on the retention and seating of complete cast crowns made for extracted human teeth prepared with a diamond bur. Under a static load, the castings failed to seat by a mean value of 203 micron. When dynamically loaded, the castings seated an average of 14 micron beyond the point of precementation measurement. No statistically significant differences were found in the retention of the crowns cemented by the two different methods.
