Objective: The purpose of this study is to compare the retention of palate-less versus complete palatal coverage dentures fitted with zirconia mucosal inserts. Materials and Methods: Fourteen male patients received upper complete dentures fitted with zirconia mucosal inserts. Half of the dentures were fabricated with complete palatal coverage (Group I) and the other half was palate-less (Group II).Retention was measured for all patients using force measurement gauge through six months follow-up period. Results: Both groups showed increase in denture retention through the follow-up period however, dentures with complete palatal coverage (Group 1) showed higher mean values of retention compared to palate-less dentures (Group II) at all follow up periods. Conclusion: Both denture designs showed satisfactory values of retention yet, dentures fabricated with complete palatal coverage showed higher values of retention than palate-less dentures.
