a Mean and standard deviation (SD) of occlusal contact area at each of the four times. The horizontal label axis was the time stage (1) before implant surgery with the complete denture in situ and (2) right after with provisional implant, (3) 1–2 weeks and (4) 3 months after insertion of the provisional screw-retained restoration, and the label to the vertical axis was contact area (mm2). The occlusal contact area was increased at 3 months after wearing implants (paired t test, p < 0.005). *p < 0.005, significant difference between conditions. b Mean and standard deviation (SD) of bite force at each of the four times. The horizontal label axis was the time stage, and the label to the vertical axis was bite force (N). The approximate maximum bite force was increased at 3 months after wearing implants (paired t test, p < 0.005). *p < 0.005, significant difference between conditions. c Mean and standard deviation (SD) of glucose data at each of the four times. The horizontal label axis was the time stage, and the label to the vertical axis was glucose data of Glucosensor value (mg/dl)
