ShanghaiMay 28, 2026 /PRNewswire/ — On May 26, the “GS Technology Concave Malformation Special Training Course,” hosted by Zhengya Dental, concluded successfully in Shanghai. The training course focused on the core theme of “Formulation and Practice of Two-Phase Remediable Treatment Plans Based on Growth Prediction,” with lectures led by Professor Shen Gang of Taikang Dental, and co-taught by clinical experts including Dr. Xu Ziqing and Dr. Wang Xingxing from Zhengya.
The training course attracted over 250 orthodontists from domestic regions and countries including the United Kingdom and Singapore. Participating experts engaged in systematic discussions on Professor Shen Gang’s diagnostic classification system for malocclusion and case analyses, delving into the latest achievements of the Shen Gang orthodontic team in applying jaw position reconstruction technology to the diagnosis and treatment of convex and concave deformities.
Theoretical Foundation: Three Key Stability Factors in Jaw Position Reconstruction
During the lecture, Professor Shen Gang reviewed the diagnostic classification methods for convex deformities, emphasizing the guiding role of a classification system based on facial features and underlying causes in developing individualized plans. He clarified the three theoretical foundations of jaw position reconstruction:
- Stability of the disc-condyle-fossa relationship
- Stability of cusp-fossa interlocking
- Stability of muscle habits
Professor Shen noted that a deep understanding and application of these three factors are key to achieving stable jaw position remodeling and enhancing long-term treatment controllability. Subsequently, Dr. Xu Ziqing, drawing on extensive clinical cases, demonstrated the clinical advantages of the GS series device S8-SGTB in precise arch expansion, early alignment and leveling, vertical control, and molar distalization.
Full-Cycle Management: Remediable Diagnostic and Treatment Framework for Concave Deformities
The afternoon session focused on the diagnostic classification and growth prediction of concave deformities. Dr. Wang Xingxing systematically elaborated on the distinguishing features of alveolar, jaw-positional, and skeletal concave deformities, proposing a treatment framework that is age-specific, stage-based, and remediable. This framework emphasizes scientifically implementing three-phase, two-phase, or single-phase treatment plans for patients of different ages, while reserving remediable pathways to effectively address dynamic changes during growth and development.
Global Physician Feedback: Rising Influence of Chinese Original Technology
The training course received high praise from attending physicians both domestically and internationally. Many experts believe that the jaw position reconstruction technology based on growth prediction, proposed by Professor Shen Gang’s team, provides highly practical clinical pathways for the systematic treatment of complex malocclusion.
Dr. Stephen Dega from the UK remarked: “Professor Shen Gang’s theoretical system of jaw position reconstruction is logically clear. The condyle’s movement trend is ultimately forward and outward, rather than backward displacement—this can be described as a paradigm shift in diagnostic concepts. Especially when considering the broader direction of maxillofacial health prevention and airway health protection, the industry is moving in the right direction, which is truly exciting.”
Dr. Rocio, also from the UK, said in an interview: “In Europe, whether for children or adult patients, conventional treatment still primarily relies on traditional braces or orthognathic surgery. Now, we are learning to apply mandibular advancement jaw position reconstruction technology, which effectively reduces dependence on surgery. It is an outstanding innovation.”
The successful holding of this training course marks the gradual expansion of the influence of the jaw position reconstruction theoretical system led by Professor Shen Gang on a global scale. By deeply integrating diagnostic classification, growth prediction, and full-cycle treatment, Zhengya’s GS technology is helping Chinese original orthodontic technology exert a more significant influence on the global academic stage.
