    Regarding VAS, participants were asked to score their answer according to the amount of satisfaction on a 100mm line (Score zero = no satisfaction at all and score 100 = complete satisfaction). The questions cover several items related to prosthesis such as: retention, stability, comfort, ease of cleaning, ease of speaking, ease of chewing, limited activities due to embarrassment, quality of bolus and appearance
