Primary Outcome Measures

Name	Time	Method
1. Retention Measured as force required to dislodge the complete denture. This will be measured using a gauge attached to denture and face bow placed on participants face. Recording is done by taking 5 readings and determining the mean score.2. Plaque accumulation Determined by standard scoring scale- Modified Quigley-Hein visual scoring Scale-.

Secondary Outcome Measures

Name	Time	Method
