Design outcomes

Primary

MeasureTime frame
To test whether or not the ADLC system results in superior VAS scores in terms of retention compared to the LOC system after 6 months applying a cross-over design.Timepoint: T0: Baseline (1 week after insertion of denture) T1: 1 month following insertion of denture T2: 3 months following insertion of denture T3: 6 months following insertion of denture—

Secondary

MeasureTime frame
Patient-reported outcome measures (PROMs) Stability of the prosthesis, maintenance of oral hygiene, ability to speak, comfort and esthetics be evaluated using VAS scores. Assessment using OHIP-14 questionnaire. Cost effective analysis for both the attachment system. Technical outcomes Timepoint: T0: Baseline (1 week after insertion of denture) T1: 1 month following insertion of denture T2: 3 months following insertion of denture T3: 6 months following insertion of denture T4: 1 year following insertion of denture T5: 3 years following insertion of denture T6: 5 years following insertion of denture—
