On the morning of October 20, 2026, Dr. Zhang Huihui, Director of Aesthetic Dentistry at Chengdu Anyu Dental Implant Hospital, successfully performed a Straumann® Emdogain® (Enamel Matrix Derivative) periodontal tissue regeneration surgery for a middle-aged female patient suffering from periodontitis. The surgery proceeded smoothly and steadily as scheduled. As the first clinical application of EMD material in the region, this milestone procedure fills a local clinical gap, marking the official introduction of this international cutting-edge periodontal regeneration technology to the hospital.
Smooth Surgery, Achieving a Regional "Zero Breakthrough"
The patient was a middle-aged woman with periodontitis who strongly desired to preserve her natural teeth instead of extracting them. Prior to the surgery, Dr. Zhang Huihui's team conducted a comprehensive examination and evaluation of the patient's periodontal condition to formulate a tailored surgical plan. During the operation, the procedure went smoothly and steadily, with the patient remaining in excellent condition. As the region's inaugural application of this biomaterial, the successful execution of this surgery provides a novel technical pathway for local periodontal regeneration treatments.
Flowers and Group Photos: Jointly Witnessing a Milestone Moment
Following the surgery, Dr. Zhang Huihui, a Straumann regional representative, and the patient held a flower presentation ceremony and took a commemorative group photo in a warm atmosphere. The Straumann representative attended the event specially to witness the historic first clinical application of Emdogain® in the region and extended congratulations on the smooth completion of the procedure.
30 Years of International Validation: True Tissue Regeneration
The Emdogain® used in this surgery is a periodontal regeneration biomaterial developed by the Straumann Group, manufactured at the Biora facility in Sweden, and supplied to the Chinese market by Straumann. According to post-surgery remarks by Dr. Zhang Huihui, the core component of this material—EMD (Enamel Matrix Derivative)—is a bioactive agent in the field of periodontal tissue regeneration that has been applied overseas for 30 years, backed by a vast collection of clinical cases and literature support. As a first-generation certified lecturer for the "Emdogain® China SQUAD Leader Training Program" initiated by Straumann, Dr. Zhang recently returned from an advanced academic study tour in Europe and has now successfully put the acquired techniques into clinical practice.
Discussing the biomaterial, Dr. Zhang noted that conventional bone grafting and soft tissue grafting typically result in a long junctional epithelium rather than forming a true new periodontal ligament. In contrast, after applying EMD, the material can induce the formation of new cementum, a functional periodontal ligament, and new alveolar bone on the root surface. "This represents true tissue regeneration in the truest sense, rather than simple reconstruction," she emphasized. She also reminded patients that not all periodontal cases are suitable for this treatment; a professional examination and comprehensive evaluation are required before formulating a tailored plan. Patients who wish to preserve their natural teeth are welcome to visit the hospital in Chengdu for evaluation and consultation.

Moving Toward "8020": Helping More Natural Teeth Stay
"I believe that with the promotion of EMD in China, an increasing number of natural teeth will be preserved, truly realizing the national '8020' goal—having 20 natural teeth at the age of 80," said Dr. Zhang Huihui. "We hope to work together with Straumann to provide better treatments for more patients". The successful implementation of this regional first Emdogain® clinical application at Chengdu Anyu Dental Implant Hospital marks another milestone in aligning the hospital with international cutting-edge periodontal regeneration technologies. Moving forward, the hospital will continue to introduce advanced technologies and concepts, continuously elevate regional periodontal diagnosis and treatment standards, and safeguard patients' natural tooth health.
