Recently, Hangzhou DTC Medical Devices Co., Ltd. was officially granted a utility model patent by the China National Intellectual Property Administration (CNIPA) for its self-developed "Orthodontic Buccal Tube Convenient for Archwire Insertion" (Patent No.: CN 224292022 U) . This achievement expands DTC's core patent portfolio in the orthodontic field and reflects the company's persistent investment and technical accumulation in medical device research, development, and innovation.
In clinical orthodontic treatment, buccal tubes are essential components of fixed appliances, designed to accommodate the archwire and guide tooth movement. However, traditional buccal tubes often present operational challenges during archwire insertion. When clinicians use instruments to grip and slot the archwire, minor hand tremors or instrument slippage can cause the archwire to fall out. Because archwires are highly elastic, they tend to spring back or shift when bent in complex configurations. If the wire slips out, clinicians must readjust and repeat the insertion steps, which not only extends chair time but also increases the risk of archwire deformation from multiple attempts, thereby impacting patient comfort.
To address this clinical challenge, the DTC R&D team developed this novel orthodontic buccal tube after extensive technical exploration. The patented design features a coordinated structure comprising a baseplate, a tube body, an elastic component, and a limiting block with a slanted edge. During insertion, when pressure is applied to the slanted edge, the limiting block automatically shifts downward, compressing the elastic component to provide reliable guidance and positioning for the archwire. Once the archwire is successfully inserted, the cooperative action of the elastic component and the limiting block effectively locks and secures the wire in place, preventing accidental detachment.
Beyond optimizing the insertion mechanism, the design also prioritizes clinical safety and patient comfort. The buccal tube incorporates fixing blocks on both sides of the inner body, along with curved plates featuring curved grooves. During archwire insertion, these grooves align with the wire's outer profile to provide directional guidance, significantly reducing friction.
Additionally, when the protruding blocks snap into the fixing slots, the curved plates are securely locked. This structure serves as a physical barrier at the archwire slot and the wire's end, preventing the wire tip from scratching or irritating the patient' s oral mucosa in the complex oral environment. This clinician-friendly design streamlines workflow while enhancing the overall patient experience.
As an enterprise specializing in the R&D, manufacture, and sales of orthodontic medical devices, DTC recognizes that independent research and technical innovation are key drivers of corporate development. Over the years, the company has consistently allocated resources to R&D funding, manufacturing equipment, and technical talent, while building a robust intellectual property protection and management system. The grant of this patent is a reflection of DTC's steady R&D progress. Throughout our development process, we remain committed to a clinical-need-driven philosophy, striving to resolve practical clinical challenges through precise structural improvements.
Looking ahead, DTC will continue to uphold its brand philosophy of "pursuing excellence and serving clinical needs" by stepping up its research efforts in material science, precision manufacturing, and digital orthodontic technologies. We aim to accelerate the transformation of patented technologies into clinical applications, striving to provide orthodontists and patients worldwide with safer, more efficient, and more comfortable integrated orthodontic solutions, while supporting the high-quality development of the dental industry.
