Objective.The purpose of this study was to measure and comparison the maximum bite forces of acrylic and flexible partial dentures in patient with free end edentulous area during different adaptation period. Subjects/ Methods. In this intra-individual study twenty four free end extension patients (FEE) were be selected, twelve of them having Kennedy Cl. I against natural dentition, while the remaining 12 patients having Cl. I against Cl. I Kennedy classification. Three testing sessions made for both types of partial denture that used in this study, by using a portable occlusal force gauge, and each patient was instructed to bite as hard as possible on the gauge. Then, the measurements done at the first day of insertion of the partial denture ,after 10 days, after the 30 days, and lastly after 90 days from insertion for the flexible denture first then for acrylic denture or the opposite. Results. There is a significant differences were found in the values of maximum bite force between the two types of partial dentures with mean of (39.9375±1.04949) for the acrylic denture and (72.39±3.07194) for the flexible denture in all adaptation periods in group one, and with mean of (28.6250±0.69038) for the acrylic denture and (51.7292±1.37954) for the flexible denture in all adaptation periods in group two. Conclusion.The flexible partial dentures give highest values of the maximum bite force in all adaptation period than the acrylic partial dentures, the maximum bite force was increased with increased the adaptation period, and the patients in group one have the highest maximum bite force than group two in both types of partial denture and in all adaptation periods.
