摘要

Denture defects affect patients’ aesthetic appearance and masticatory function, thus reducing their quality of life. There are many ways to repair denture defects, among which removable partial dentures are a basic and widely used method. The purpose of this study was to compare the clinical performance of Bio-HPP and Vitallium frameworks in the restoration of free-end removable partial dentures. 80 patients with free-end removable partial dentures treated at the Stomatology Hospital of Xi’an jiaotong university from January 2022 to March 2023 were randomly divided into two groups. 40 patients in the control group received Vitallium frameworks and 40 patients in the observation group received Bio-HPP frameworks. The abutment tooth mobility, gingival index, and patient satisfaction after one year of restoration were compared and analyzed between the two groups using an Independent T-test. P < 0.05 was considered significant. All our experiments were carried out in accordance with relevant standards and regulations of Stomatology Hospital of Xi 'an Jiaotong University. After 1-year follow-up, in terms of aesthetics, comfort, and patient satisfaction, Bio-HPP was significantly superior to Vitallium frameworks, whereas the opposite was true for denture stability (P < 0.05). Besides, there were no significant differences in the mobility of abutment teeth and gingival index between Bio-HPP and Vitallium frameworks (P > 0.05). Both Bio-HPP and Vitallium frameworks can be used in restoring free-end removable partial dentures and the performance of the restorations was clinically acceptable. However, Bio-HPP has unique advantages in terms of aesthetics and comfort.
