title: [The quantitative study of retentive characteristics and masticatory efficiency of complete overdentures retained by magnetic retainers].
abstract: In order to evaluate the role of magnetic retainers for the retention of complete overdentures, the authors applied self-made measuring instrument and absorbent methods to measure the real retentive force and masticatory efficiency quantitatively at pre- and post installation of magnetic retainers in the complete overdentures. The results showed that the retentive force of the denture in the mouth increased about 1500g which was 78.95% measured extraorally; the masticatory efficiency of the patients was 1/3 higher after installation of magnetic retainers in the dentures than before which meant that the denture fitting time of the patient could be shortened.
