20例上颌无牙颌种植固定修复的临床疗效观察

Abstract

Abstract: Objective To retrospectively analyze the clinical effect of implantsupported fixed dental prostheses in patients with edentulous maxillaries. Methods A total of 109 implants in 20 patients with edentulous maxillaries in the Affiliated Stomatological Hospital of Nanjing Medical University from January 2017 to January 2020 were reviewed. Panoramic radiographs were taken immediately after the operation and during the followup, and the implant survival rate and periimplant marginal bone loss (MBL) were observed and compared. The clinical effect was measured by the OHIPEDENT questionnaire (Oral Health Impact ProfileEDENT) and a visual analog scale (VAS), and SPSS software was used for descriptive statistical analysis. Results During the followup, 3 out of 109 implants were removed due to the failure of osseointegration, and the implant survival rate was 97.24%. The MBL was about 0.74 mm/year; the average score of the OHIPEDENT questionnaire was 8.00, and the VAS score was 9.15 on average. Conclusion The shortterm clinical effect of maxillary edentulous implantsupported fixed dental prostheses is stable, and patient satisfaction is high.
