The origin of clinical practice - Implants

My clinical practice is rooted in implant treatment. I studied implantology and oral regenerative medicine at the Tokyo Medical and Dental University Graduate School, where I learned to treat the entire oral cavity, including bone, gums, prosthetics, occlusion, and remaining teeth.

​

From Implants to Digital Orthodontics: While continuing implant treatment, I strongly felt the importance of not only replacing missing teeth but also correcting the position, alignment, and occlusion of remaining teeth. While incorporating Invisalign, which was cutting-edge at the time, into my clinical practice, I also worked with Ken Dentalix Co., Ltd. to develop our own digital aligner system, "Anligner," utilizing CAD/CAM and 3D digital technology. The name "Anligner" incorporates my own surname, Ahn.

2014-2016: Presented at the 1st to 3rd annual conferences of the Japan Aligner Orthodontics Research Society for three consecutive years.
2018-2019: I worked as a researcher in the Department of Orthodontics at Yonsei University College of Dentistry in South Korea, further deepening my research and clinical perspective in orthodontics.

Clinical experience in China

My involvement with China began when I visited the country to provide education and guidance on implant treatment. Subsequently, I worked as an implant specialist, engaging in clinical practice and education at prominent private medical institutions throughout China, including Shanghai Punan General Hospital and the Meilai Aesthetic Medical Group. My experience in the diverse medical environments of Japan, South Korea, and China has led to ANBI's current treatment style, which considers "implants x orthodontics x aesthetics" as a single treatment plan.

Cosmetic dentistry, and the smiles of our patients.

Through clinical practice in China, I interacted with leading clinicians in aesthetic dentistry in Korea and learned about minimally invasive aesthetic treatments that combine digital technology and advanced dental techniques while preserving natural teeth as much as possible. What impressed me most was seeing the change in patients' expressions when they looked in the mirror after treatment, and their genuinely happy smiles. From that experience, I began to design implants, orthodontics, and aesthetics not as separate treatments, but as a single treatment plan from the beginning. Rather than sacrificing quality of treatment to speed it up, I aim to reduce unnecessary steps and waiting times with digital technology, and to proceed with medically feasible treatments simultaneously, thereby reducing the burden on patients and the overall treatment period.

Feel safe and beautiful.

Papers/Research

​

2021 | Original Research Paper, First Author / Doctoral Dissertation: "A Study on Changes in Maxillary Alveolar Arch Morphology After Implant Treatment in the Cleft Alveolar Region"

Changes in maxillary dental arch morphology after implant treatment in the alveolar cleft region.
Ahn K, Sato H, Kurihara Y, Ogura H, Shirota T.
Clinical and Experimental Dental Research. 2021;7(4):484-489.
DOI: 10.1002/cre2.384 / PMID: 33342089

This research was conducted with Yoshiyuki Yasui as the lead author. It evaluated how the morphology of the maxillary alveolar arch and dental arch changes after implant treatment in the cleft dentition, examining not only the implant prosthetics in the missing tooth area but also the overall changes in the dental arch after treatment. This research linked implant treatment with orthodontics and dental morphology, and Yasui obtained his doctoral degree with this research as his main dissertation. This research also aligns with his current clinical philosophy of "not considering implants and orthodontics separately."

2017 | Maxillofacial Implants and Oral Function Reconstruction: "Three Cases of Improvement in Oral Function Using Maxillofacial Dentures with Locator Attachments After Head and Neck Cancer Surgery"

This report presents three cases of patients who underwent head and neck cancer surgery and received prosthetic rehabilitation using implants and locator attachments, with the aim of improving oral function with maxillofacial prostheses. It addresses not only the prosthetic treatment of missing teeth, but also the application of implant treatment to consider functional recovery and quality of life (QOL) in postoperative patients.

Research presentation at the Showa University Alumni Association: "A study on changes in maxillary alveolar arch morphology after implant treatment in the cleft palpebrae."
This research presentation, which examined implant treatment in the cleft palpebrae and changes in maxillary alveolar arch morphology, is a topic that will later lead to an English-language academic paper and a doctoral dissertation.

Major academic presentations and lectures in the field of implantology

​

2011｜European Association for Osseointegration (EAO) 20th Annual Scientific Meeting, Athens

"Research on changes in occlusal force due to implant prosthetics for unilateral free-end molar defects"
Alteration of occlusal force in unilateral free-end molar missing cases by implant prosthesis
Yoshiyuki Yasui, Makoto Shiota, Chiharu Imakita, Shinji Kuroda, Shohei Kasugai / Department of Implant Oral Regeneration Medicine, Tokyo Medical and Dental University. This study examined changes in occlusal force before and after implant prosthetics in cases of unilateral free-end molar ostosis. It evaluated not only the recovery of occlusal force but also its impact on the occlusal balance between the left and right sides, viewing implants not merely as prosthetic replacement for missing teeth, but as a means of restoring the overall function of the oral cavity.

​

2016 | The 33rd Kyushu Branch Annual Meeting of the Japanese Society of Oral Implantology - Special Lecture: "The Status of Dental Implants in South Korea and China"

I was invited to give a special lecture, and based on my clinical experience in South Korea and China, I spoke about the current state of implant treatment in both countries, the clinical environment, treatment systems, market development, and the future of implant dentistry in Asia.
