Konsultasi dengan dokter gigi di Bauhinia Dental

Purple Orchid Dental is a private clinic network established in 2026. It operates three locations across Hong Kong and Shenzhen. Dr. Zhu Shengji founded the facility to provide cross-border dental care. He is a Hong Kong government-registered dentist with doctoral studies at Peking University. He also trained at the University of Edinburgh Royal College of Surgeons. The network runs two specialized units in Shenzhen and one outpatient clinic in Hong Kong.

Key Facts & Achievements

The network employs eight doctors across four departments. They trained at the University of Hong Kong, Peking University, and Nanjing Medical University. The team includes a member of the American Academy of Cosmetic Dentistry. Another doctor belongs to the World Federation of Orthodontists.

Specialties & Procedures

The clinic provides targeted dental care across multiple specialties:

Orthodontics and Clear Aligner Therapy

The orthodontic department creates customized care plans using clear and traditional brackets. Doctors correct bite alignment with several systems:

• Invisalign clear aligners
• Ceramic braces
• Self-ligating braces
• Lingual braces
• Traditional metal braces

Dentists use specialized imaging to assess bone and tooth positions before planning treatment. Team specialists hold official Invisalign certifications.

Aesthetic Restorative Dentistry

The restorative department improves tooth appearance and function. Specialists perform resin restorations to repair chipped or decayed teeth. The clinic also provides custom porcelain veneers and full ceramic crowns. These restorations cover surface defects and strengthen damaged structures.

Dental Implantology

For patients with missing teeth, the clinic offers implant surgery using Swiss-made Straumann Dental Implants. This system provides reliable osseointegration – where bone grows around the implant. Dr. Li Xin focuses on implant care. Dr. Wang Ting holds a PhD in prosthodontics, so she manages complex tooth restorations.

Periodontal Care and Oral Surgery

The clinic operates a periodontal disease center to treat periodontitis and periodontosis. Doctors use ultrasonic equipment for supragingival cleaning and subgingival scaling. These techniques remove calculus from above and below the gumline.

For severe gum disease, surgeons perform flap surgery or apply semiconductor and water lasers. General surgical treatments include standard extractions and wisdom tooth removal. Fully erupted wisdom teeth take under 30 minutes to remove. Impacted teeth require one hour or longer. After surgery, the clinic tracks recovery through a follow-up program to reduce infection risks.

Teeth Whitening

The clinic offers two whitening options:

• In-clinic whitening completed in 1–2 sessions
• Home whitening using custom trays worn 15–30 minutes daily

Over 90% of patients achieve satisfactory results. Dentists treat cavities and gum issues first to prevent sensitivity. For home treatments, patients receive custom trays during two visits. Mild sensitivity may occur but resolves when treatment stops.

Equipment & Technologies

The clinics use specialized diagnostic equipment:

• CBCT – 3D dental imaging for precise bone assessment
• Panoramic X-ray systems for full-jaw views
• Periapical X-ray imaging for targeted tooth root inspection
• CEREC Omnicam – digital scanning to create 3D dental models

Digital scanning replaces traditional paste impressions, which improves patient comfort.

Services for International Patients

Purple Orchid Dental coordinates care continuity between Hong Kong and Shenzhen. The clinic participates in the Hong Kong Elderly Medical Voucher program. Eligible seniors can use government vouchers at both Shenzhen locations. The clinic also integrates with Hong Kong's medical health app. This lets users access their cross-border health records directly at the Shenzhen clinics.
