Abstract: Objective: To observe the effect of minimally invasive tooth extraction and immediate implant technique in 42 cases of anterior tooth restoration. Methods: A total of 84 patients with missing maxillary anterior teeth who were admitted to the Department of Stomatology, Yuebei People’s Hospital from May 2017 to May 2018 were selected as the research objects, and they were divided into an immediate group and a delayed group (42 cases in each) using a random number table method. The immediate implantation technique was implemented after minimally invasive tooth extraction in the immediate group, and the delayed implantation technique was implemented after minimally invasive tooth extraction in the delayed group. The aesthetic effects and restoration satisfaction of the two groups were observed. Results: There was no statistical significance between the red aesthetic index and white aesthetic index scores of the two groups at the completion of the restoration (P>0.05), the red aesthetic index and white aesthetic index scores of the two groups were higher than that at the completion of the restoration 6 months after the restoration, and the immediate group was significantly higher than the deferred group (P<0.05), the repair satisfaction score(9.08±0.85) of the immediate group was significantly higher than the deferred group(8.13±0.93) after 12 months of repair. Conclusion: The minimally invasive tooth extraction and immediate implant technique can effectively improve the aesthetic effect and satisfaction of patients with maxillary anterior tooth loss, and can be widely used in clinical practice.
