D4 is committed to researching digital design, optimizing service processes, utilizing advanced diagnostic instruments, and implementing precision customized treatment plans. This commitment aims to avoid the repetitive adjustments often associated with traditional treatment methods, striving to provide professional, suitable, and health-focused personalized designs and treatments.

Pursuing the industry goal of 'high quality, high standards,' D4 consistently makes maximum efforts to ensure that every customer experiences the transformative changes that come with unlocking their aesthetic potential.



D4 is the first domestically authorized and designated collaboration room for the Philips Zoom brand.

As a Philips teeth whitening collaboration experience clinic and a pre-market testing clinic for product launches, D4 has developed special strategies tailored to the teeth whitening needs of Asians. Dr. Xu Hengkai, as a gold-medal lecturer invited by Philips, offers customers the most comprehensive and safe Philips Zoom teeth whitening treatment in the country.


D4 has dedicated pediatric-friendly treatment rooms equipped with projectors to alleviate the anxiety of children during dental visits. The clinic uses internationally renowned 3M fluoride varnish to ensure the well-being of children's teeth.

Implementing the Finnish Romo Bite Induction system, accredited by the U.S. FDA, EU CE certification, and China CFDA medical device registration, D4 provides a reliable approach to guide occlusal development. Additionally, the clinic utilizes the Invisalign First orthodontic system from the United States, employing digital design for children's invisible orthodontics. This system monitors and guides oral and facial development from early childhood to adolescence

D4 adopts the Swiss Straumann implant system, which boasts the highest global market share. Straumann® represents top-tier Swiss quality, precision, and innovation, backed by a robust global scientific network, providing assurance in the field of dentistry. D4 exclusively utilizes the Straumann® implant system, ensuring that each implant is placed under the guidance of a fully navigated implantation process using 3D-printed surgical guides after a digital design plan.

This approach guarantees the safety and reliability of each implant treatment for every patient at D4. The restoration not only focuses on functional aspects but also considers aesthetic bite function and facial support. It aims to avoid the human errors associated with traditional implantation methods.

For the past five years, D4 has been implementing a comprehensive digital clinic solution, establishing digital model archives for every patient. This ensures that each patient visiting D4 retains digital models from different periods, preserving optimal oral bite data for potential future treatments, such as restoration, orthodontics, and bite reconstruction, accounting for natural wear and tear over time.

The clinic also provides referenceable pre- and post-treatment data for each procedure, preparing for future comprehensive digital oral and facial solutions. Simultaneously, it offers robust diagnostic evidence for pathological changes in the oral cavity that may occur over time.


Digital Smile Design (DSD) is a modern cosmetic dentistry technique that utilizes computer-aided design and digital imaging technologies to simulate the perfect smile. The DSD technology helps dentists and patients communicate and collaborate more effectively to achieve the desired smile outcome.

Through digital imaging, patients can preview and confirm the effects of cosmetic dentistry treatments before and after, providing them with greater confidence in undergoing the procedures. DSD technology finds wide applications in repairing tooth defects, enhancing tooth color, and adjusting tooth positions, among other aspects of dental aesthetics.

My apologies for that oversight. Here is the translation into English:

Bracket Correction: This is the most common orthodontic technique. Dentists install metal brackets and wires on the patient's teeth and gradually adjust the tension and force of the wires to move the teeth into the desired positions.

Invisible Correction: This is a bracket-free orthodontic technique that uses transparent braces or aligners. While ensuring effectiveness, this method provides a more discreet way of orthodontic correction, less noticeable to others.
