There are numerous gender differences in reported preferences on oral health. This Canadian study examined the satisfaction of edentulous men and women randomised to mandibular CDs (52 ♂, mean age 73 yrs; 65 ♀, 71) and IODs (51 ♂, mean age 72 yrs; 62 ♀, 73), in both cases opposed by maxillary CDs. All subjects were previous CD wearers and suitable for 2 implants with ball attachments.

There were 15 drop-outs from the IOD group, and 11 from the CD group. Both groups significantly improved satisfaction from baseline to 6 and 12 months after denture insertion. In the CD group only, females rated both aesthetics and chewing ability lower than males at 6 months, and aesthetics alone at 12 months. Gender ratings for overall satisfaction, comfort, stability, speaking ability and ease of cleaning did not differ in either group. There were no gender differences in the IOD group.
