The 2026 ICOI (International Congress of Oral Implantologists) Japan Chapter General Assembly and Scientific Conference will be held over two days, Saturday, November 14 and Sunday, November 15, 2026, at Bellesalle Shinjuku South Exit in Shinjuku, Tokyo. As Conference Chair, I sincerely welcome you all to attend.
In recent years, implant treatment has advanced significantly due to progress in digital technology and materials, making safer and more predictable treatments possible. At the same time, Japan is facing a super-aging society unparalleled anywhere else in the world, and the role expected of us in dental care is also changing. In a society with an aging population, it is becoming more important than ever to select treatment options that take into account the patient’s overall health and lifestyle, while keeping in mind the long-term maintenance of oral function.
The theme of this conference
is "Minimalism in Implant Dentistry – What Do Patients Really Want?"
In implant dentistry, the goal is not merely to perform highly advanced procedures. We believe that the future of implantology requires us to identify what truly constitutes valuable treatment for patients and to provide necessary and appropriate care while avoiding excessive invasiveness and overtreatment.
For this conference, we have invited clinicians and researchers active both domestically and internationally to discuss “the future of implant treatment” from various perspectives, including digital technology, minimally invasive treatment, prosthetic design, and long-term prognosis. We also hope this will serve as an opportunity to reflect on the significance of implant treatment in a super-aging society and the role of implantology as patient-centered care.
Furthermore, we hope this conference will serve as a venue for learning and networking not only for dentists but also for dental hygienists, dental technicians, and students, providing an opportunity to gain new insights and build professional networks.
We sincerely look forward to meeting you all in Shinjuku, Tokyo. We sincerely hope to see many of you there.

Using models, participants will practice filling extraction sockets with bone graft material, placing membranes, and performing soft tissue grafting using the VISTA technique.
The Sinus Optimization Strategy (SOS) proposes a streamlined, graftless approach to sinus elevation designed to reduce complications, shorten healing time, and enhance predictability in implant dentistry. This concept focuses on maximizing the natural osteogenic potential of the Schneiderian membrane and surrounding sinus walls, allowing clinicians to achieve vertical bone gain without the routine use of grafting materials. By emphasizing atraumatic membrane handling, precise pre-operative diagnostics, and controlled intra-sinus space creation, SOS reframes the sinus lift as a biologically driven process rather than a graft-dependent procedure. Clinical observations suggest that minimizing foreign materials may reduce postoperative inflammation, membrane perforation risk, and graft-related morbidity, while still supporting stable implant integration. The SOS framework provides clinicians with a simplified, biologically conservative pathway for managing posterior maxillary atrophy, one that prioritizes patient comfort, procedural efficiency, and long-term implant success.
