Abstract
Abstract
Objectives: The aim of this study was to evaluate the passivity achieved by different impression techniques, conventional and digital one for implant assisted mandibular bar over denture.
Materials and methods: Each of the eight healthy, fully edentulous individuals received four implants in the mandibular interforaminal space. Two bars were given to each patient, one made using the traditional impression method and the other with the digital impression method. Periapical radiography and the Sheffield one screw test were used to evaluate passivity.
Results: There was a significant difference in passivity between the conventional and the digital impressions which show better results and less gap between bar and terminal implant by one screw test.
Conclusion: Regarding the passivity, digital intraoral scanning technique had more favorable clinical outcomes compared to conventional impressions technique in the construction of bar mandibular overdenture assisted by four implants.
