  Abstract: Objective:To evaluate the impact of bonded provisional restorations after bone augmentation for single-tooth implantation in the aesthetic zone on the surrounding soft tissues and patient satisfaction, and to explore its clinical restoration effect.Methods: Thirty patients who underwent single-tooth implantation in the aesthetic zone of the maxillary anterior teeth and simultaneous horizontal bone augmentation in the Department of Stomatology of the First Affiliated Hospital of Wenzhou Medical University from March 2022 to March 2024 were selected, with 15 cases in each of the study group and the control group.The study group used digital intraoral scanning technology and CAD/CAM technology to fabricate personalized milled resin teeth;the control group used traditional metal winged provisional bridges.After permanent restoration,the soft tissues were evaluated aesthetically,and the implant survival rate and the provisional restoration dropout rate were statistically analyzed.Patients were also asked to evaluate their satisfaction with the clinical effect of the provisional restoration. Results: At the end of the observation period,93.33% (28/30) of the provisional restorations remained.All 30 aesthetic zone implant restorations were successfully restored,with no early implant failure or bone augmentation failure requiring reoperation.The mean PES score was 10±1.55 in the study group and 9.13±1.81 in the control group, both within the 8 to 12 range.The total scores of patient satisfaction evaluation were high in both groups, but the mean score was higher in the study group, and the difference was statistically significant.In terms of pronunciation,foreign body sensation, and color scores,the mean scores of the study group were higher than those of the control group, and the differences were statistically significant. Patients in the study group had higher satisfaction than those in the control group.Conclusion:Within the limitations of this study, the clinical outcome of using bonded provisional restorations after bone augmentation for single-tooth implant placement in the aesthetic zone was favorable in terms of soft tissue aesthetics and patient satisfaction. Personalized milled resin provisional restorations were relatively better, but the indications should be well controlled.
