title: [Experimental study on fitness of retainers of one-piece casting frameworks of distal-extension implant denture].
abstract: An experiment on fitness of retainers of one-piece casting frameworks was performed between two non-noble metals and among three of abutment positions fixture implant with a coordinate measuring machine for three-dimensional analysis. The results showed that there was no statistically significant differences in retainer fitness between the two metals, and among the three fixture abutment positions. However, all retainer displayed shrinkage in three dimensions, and the retainer shrinkage on the cervical surface were more than on the occlusal surface. The fitness of retainers of one-piece casting frameworks would be improved if used in multi-unit implant fixed denture.
