[The comparison of three methods for plat castable ceramic crowns].
The adaption of ceramic crown is a critical factor. This study compared the adaption of Plat castable ceramic crowns made by three methods. These are the first, routine method, the second, die spacer technique and the third, model investing method. The average adhesive thickness at different parts of crown of these three crown groups are 157 microns, 65 microns, 41 microns and at the margins are 261 microns, 46 microns, 33.4 microns respectively. The result indicates that the crowns making from the second and third methods could improve the adaption significantly.
