Abstract: Objective: To evaluate the short-term clinical effect and related influencing factors of Admira Fusion and BEAUTIFIL Ⅱ resin used for moderate wedge-shaped defects in senior patients. Methods: Fifty cases of patients, between 50 to 80 years old, with moderate wedge-shaped defects were selected from September 2016 to March 2017 as research objects. They were randomly divided into two groups and were treated with Admira Fusion (Group A) and BEAUTIFIL Ⅱ (Group B), respectively. The repair success rate, the edge sealing rate, the rough surface rate, the color coordination rate, the Q-H modified plaque index, and related influencing factors were followed up. The relevant clinical data were analyzed. Results: Twelve months after restoration, the success rate of Group A (96%) was significantly higher than Group B (84%) (P＜0.05). Twelve months after restoration, the edge sealing rate and the rough surface rate of Group A were 96% and 4%, respectively. While those of Group B were 84% and 16% (P＜0.05). Univariate analysis showed that the success rate of restoration was correlated with oral hygiene habits, diet, the tooth position, and chewing habits (P<0.05). Conclusion: Admira Fusion nano-resin to repair moderate wedge-shaped defects of middle-aged and senior patients has indicated better marginal sealing and excellent color match, which is worthy of wide clinical application. Thus Admira Fusion should be the preferred choice for senior patients with moderate wedge-shaped defects.
