Objective To explore the effect of wave-shaped arch in orthodontically correct dental occlusal plane canting. Methods A total of 82 patients with dental occlusal plane canting who were treated in our hospital from March 2021 to May 2023 were selected as the research objects. The patients were divided into control group and observation group by random number table method, with 41 patients in each group. The control group was treated with micro-implant anchorage, and the observation group was treated with wave-shaped arch. The duration of treatment, the degree of plane canting and oral health were compared between the two groups. Results The correction time of the observation group was (5.53±2.11) months, which was shorter than (13.25±4.82) months of the control group (P <0.05). After treatment, there was no significant difference in the average reduction of the dental occlusal plane canting angle between the observation group and the control group (P >0.05). There was no significant difference in the scores of oral cleanliness, occlusal function, masticatory function and pronunciation function between the observation group and the control group after treatment (P >0.05). Conclusion The wave-shaped arch has a reliable effect on the treatment of dental occlusal plane canting, which is equivalent to the effect of micro-implant anchorage, but it can shorten the treatment course, effectively improve the degree of plane canting, and improve the oral health status.
