Fig. 4
Occlusal force according to dental status with NRT (high and moderate groups). Two separate graphs to compared occlusal force with dental status in A high NRT group (24–32 teeth) and B moderate NRT group (16–23 teeth). A bar denotes mean value and whisker denotes standard deviation (SD). Superscriptabc denotes same subgroup by Bonferroni’s post hoc multiple comparisons test in ANOVA. Side table for high NRT group: ANOVA was applied to compare mean with SD of NT, NRT, NT-Post and NRT-Post across dental status. Side table for moderate NRT group: T-test was applied to compare mean with SD of NRT, NT, NT-Post and NRT-Post between dentate and denture (partial and complete denture) group
