In mid-to-late October, Professor Wang Jun, Director of the Department of Orthodontics at Sichuan University West China Hospital of Stomatology, appeared at academic conferences in Shenzhen and Chengdu successively, delivering special reports on the iteration of Lingual Orthodontics technology and the latest research findings on stepwise lingual orthodontics. The two reports brought the technological evolution path of "standardized lingual orthodontics — personalized lingual orthodontics — stepwise lingual orthodontics" into national and international academic view, and also made digital-intelligent stepwise lingual orthodontic treatment one of the most closely watched technological directions in the industry.

On October 15, at the "Precision · Intelligence · Future — Digital-Intelligent Lingual Orthodontics Academic Symposium" hosted by Shenzhen Stomatology Hospital, nearly 200 orthodontists and industry peers from across the country attended. The conference adopted a format combining theoretical lectures with hands-on instruction. Professor Wang Jun, starting from clinical needs, introduced the development path and related technical characteristics of Lingual Orthodontics technology.

Professor Wang Jun of West China Hospital of Stomatology pointed out that the development of Lingual Orthodontics technology is ushering in a new breakthrough. The currently closely watched digital-intelligent stepwise lingual orthodontic treatment is an innovative technology that integrates the dual advantages of Clear Aligner Therapy and lingual orthodontics: it retains the characteristics of lingual orthodontics — fixed, invisible, and not dependent on patient compliance — while introducing the stepwise treatment approach of Clear Aligner Therapy, driving lingual orthodontics from "adjustment relying on individual doctor's experience" toward "step-by-step advancement according to a pre-set plan," enabling doctors with clear aligner experience to also smoothly enter lingual clinical practice.

From the perspective of technological iteration and evolution, lingual orthodontics has gone through three stages: from standardized to personalized, and then to stepwise. In the first-generation standardized stage, lingual bracket bases and data were mainly based on standardized designs, with cumbersome processes and long time requirements; in the second-generation personalized stage, brackets could be individually designed according to patients' tooth morphology and occlusal relationships, with treatment precision and comfort greatly improved, but still highly dependent on doctors' clinical experience; in the third-generation digital-intelligent stepwise stage, the visualized planning and stepwise movement concepts of clear aligner therapy are introduced into lingual clinical practice, making complex lingual processes plannable, clinical pathways clearer, and the doctor learning curve expected to shift downward.

Professor Wang Jun stated that digital-intelligent stepwise lingual orthodontic treatment not only changes treatment tools but also broadens the clinical pathway of lingual orthodontics — it lowers the entry threshold for lingual technology and provides new possibilities for the industry's technological development.

On October 21, at the "International Symposium on Orthodontic Frontiers" (ISOF) hosted by Sichuan University, Sichuan University West China Hospital of Stomatology, the State Key Laboratory of Oral Diseases, the National Center for Stomatology, and the National Clinical Research Center for Oral Diseases, Professor Wang Jun focused on "Latest Research Progress in Lingual Orthodontics Technology," once again sharing the innovative concept and cutting-edge technology of the Stepwise Lingual Appliance, and delivered a report in English.

At the conference, international experts and scholars asked questions and exchanged views on the relevant reports, and stepwise lingual orthodontic treatment quickly became the focus of discussion. The questions and exchanges not only centered on the report content but also extended to the clinical value and promotion prospects of this technological path; from on-site interaction to discussions between sessions, stepwise lingual orthodontic treatment continued to attract widespread attention from international peers, becoming one of the most notable technological directions in this international academic exchange.

From the Digital-Intelligent Lingual Orthodontics Academic Symposium in Shenzhen to the ISOF international academic stage in Chengdu, Professor Wang Jun's two reports point to one trend: lingual orthodontics is moving from "standardized and personalized" toward "stepwise." This is not only an update of the technological path but also a shift in clinical paradigm — lingual orthodontics is moving from an era of "relying on individual experience" toward one "driven by plannable digital-intelligent solutions." When more doctors with clear aligner experience can enter lingual clinical practice, lingual orthodontics can be expected to move from "a technology mastered by a few doctors" toward standardized services that are "accessible to more doctors and available to more patients."
