Objective To investigate the effect of minimally invasive all-ceramic restoration on aesthetic satisfaction of restorations in patients with anterior tooth defect. Methods A total of 100 patients with anterior tooth defect admitted to the Department of Stomatology, Tongshan County Maternal and Child Health Hospital from January 2024 to June 2025 were selected as the research subjects. According to the random number table method, they were divided into the control group and the observation group, with 50 patients in each group. The control group was treated with traditional all-ceramic restoration, and the observation group was treated with minimally invasive all-ceramic restoration. The upper tooth defect rate, alveolar bone related indicators and aesthetic satisfaction of restorations were compared between the two groups. Results The upper tooth defect rate in the observation group (4.00%) was lower than that in the control group (16.00%) (P<0.05). After 6 months of treatment, the new bone contour and bone mineral density in the observation group were higher than those in the control group, and the vertical absorption of alveolar bone was lower than that in the control group (P<0.05). The scores of all dimensions of aesthetic satisfaction of restorations in the observation group were higher than those in the control group (P<0.05). Conclusion Minimally invasive all-ceramic restoration can improve the aesthetic restoration effect of anterior tooth defect, reduce the upper tooth defect rate, improve alveolar bone related indicators, and enhance the aesthetic satisfaction of restorations.
