[Experiment study on fit of anterior osseointegrated implant frameworks related to the number of fixture abutments].
Good fitness of osseointegrated frameworks was a key factor to protect implant for function. The purpose of this study was to evaluate the fitness of anterior implant fixed bridge in one-piece casting made of Ni-Cr alloy in different numbers of fixture abutments. The specimens were measured by the three-dimensional measurement system (German Opton uMM550). The results demonstrated that there were statistically significant differences in dimensional changes among one, two or three fixture numbers, the space of retention was 50-150 microns, and the flow of retention was 100-250 microns.
