bone density, periodontal status, teeth mobility, denture retention, stability, degree of comfort, efficiency of biting, and total serum protein in blood before and after wearing DuCo RPD. All these factors were
compared with patients before and after wearing traditional RPD. Body weight, physical signs, facial symmetry, dental caries, alveolar bone density and periodontal status were not statistically different
between the RPD and the DuCo RPD users. Bone resorption, teeth mobility and teeth loss of the RPD group were significantly higher (p < 0.05) than the DuCo RPD group. A major increase in retention and
stability (p < 0.05) were also observed for the DuCo RPD group. Patients who wore DuCo RPD had a higher biting efficiency than patients who wore RPD (p <0.05). DuCo RPD use is more practical and
patients with DuCo RPD application showed better physiological outcomes than patients with RPD application.
