Intraoral Scanning in D4 Dental Clinic

D4 Dental Clinic is a multi-specialty dental facility in Shanghai's Changning District. Dr. Herman Hsu founded it in 2020 as a center for interdisciplinary dental care. It combines restorative dentistry, orthodontics, and implants through a unified digital planning framework.

Digital Smile Design and Clinical Achievements

In 2020, D4 Dental Clinic became the first certified DSD Clinic in Asia. This designation marks it as a center for Digital Smile Design (DSD). DSD uses facial analysis and 3D imaging to plan dental outcomes before any procedure begins. The clinic holds DSD Clinics Certification with registration number CN20001.

The medical team includes six clinicians, with two DSD Master clinicians. Founder Dr. Herman Hsu serves as a DSD Instructor and Key Opinion Leader. He regularly participates in international dental education. Doctors at the clinic trained at institutions including:

• Harvard School of Dental Medicine
• New York University
• McGill University
• Shanghai Jiao Tong University School of Medicine
• University of Auckland
• University of New South Wales

Specialties and Treatment Pathways

The clinic organizes care into defined pathways. Different specialists collaborate on each patient case. This structure keeps aesthetic goals aligned with functional health and long-term stability.

Aesthetic Restorations and Whitening

Aesthetic treatments start with Mockup validation. Patients see a physical preview of their final smile before permanent changes occur. The clinic is an authorized PHILIPS ZOOM! Whitening Experience Center. Staff provide shade assessments based on the cause of discoloration.

Orthodontics and Pediatric Care

The orthodontic department treats adults and children. Digital diagnosis maps tooth movement and bite construction. Dr. Christine Chen and Dr. Joy Guo offer several options:

• Invisalign and clear aligner therapy
• Fixed orthodontics with ceramic or metal braces
• Lingual braces installed on the back of the teeth
• Early pediatric intervention to monitor growth timing

Pediatric care focuses on mixed-dentition records. This helps manage oral habits and bite development at the right stage.

Periodontal and Implant Dentistry

The Periodontal Stability Pathway is foundational at D4. It confirms gums and bone are healthy before starting implants or braces. Dr. Victor Sun and Dr. Elaine Niu focus on periodontal maintenance. This prevents inflammation around new restorations. Implant procedures use computer-assisted planning for precise placement based on digital records.

Diagnostic and Treatment Technology

The clinic follows a "records-first" workflow for accuracy. Specialists use Cone Beam CT (CBCT) to visualize bone structure and root positions in three dimensions. Digital tools include:

• Intraoral scanning for impression-free records
• Cerec Omnicam for digital diagnostic models
• Computer-aided design (CAD) software for DSD planning
• Digital bite registration systems

These technologies let the team compare periodic scans to monitor shifting or wear over time.

Services for International Patients

D4 Dental Clinic supports patients visiting Shanghai from abroad. Clinical staff offer consultations and treatment discussions in English for clear communication. The clinic provides guidance on travel timing. Staff also help patients prepare records to share before their visit. For those needing follow-up care outside China, the team helps plan maintenance with home-based providers.
