Abstract：AIM:Exploring the application effect of 3D printing technology guided enamel removal in the orthodontic treatment of malocclusion.METHODS:A total of 105 patients undergoing enamel removal orthodontic treatment on the adjacent surface of the lower dentition at the Department of Stomatology at Wenzhou Central Hospital between January 2022 and January 2023 were selected as the study population.Patients were divided into two groups based on the treatment method:an observation group(n=50),receiving 3D printing-guided precise enamel removal for adjacent orthodontic surfaces,and a control group(n=55),receiving traditional enamel removal treatment.The two groups were compared in terms of gray and hardness values,periodontal health status,dental function,aesthetic outcomes,and oral health-related quality of life.RESULTS:Post-treatment,the observation group exhibited lower gray values,gingival index,plaque index,gingival sulcus probing depth,and overall Bolton index,but higher hardness values compared to the control group(all P＜0.05).Additionally,scores for swallowing function,chewing function,dental occlusion,and pronunciation function were significantly higher in the observation group(all P＜0.05).The observation group also demonstrated better alignment of teeth,occlusion,and anterior teeth coverage compared to the control group(all P＜0.05).Furthermore,oral health-related quality of life scores were significantly lower in the observation group than in the control group(P＜0.05).CONCLUSION:The application of 3D printing technology in precise enamel removal of adjacent surfaces in orthodontics demonstrates excellent outcomes,including improved periodontal health,enhanced aesthetic results,and a better quality of life.This technique holds significant potential for clinical adoption and wider promotion.
