HOMA ZADEH
Dr. Zadeh has earned his Doctor of Dental Surgery (DDS) degree from the University of Southern California (USC) Ostrow School of Dentistry. He completed post-doctoral clinical training in periodontology, as well as a PhD degree in immunology, at the University of Connecticut Health Center (UCHC) School of Dental Medicine and School of Medicine, respectively. Dr Zadeh served as full time faculty for 28 years, earning tenure status at the USC. He served as director of postdoctoral periodontology program (2012-2019). Dr. Zadeh is internationally recognized for his clinical and scientific expertise. He has lectured nationally and internationally in over 40 countries at prestigious conferences on topics ranging from aesthetics to minimally invasive periodontal and implant surgery, as well as tissue engineering. Dr Zadeh has published over 100 journal articles in peer review journals, reviews, abstracts and book chapters.
Dr. Zadeh served as president of the Western Society of Periodontology (WSP) in 2017 and continues to serve as trustee on the board.
Dr. Zadeh is the innovator of the VISTA technique recognized around the world as one of the most effective methods for the treatment of soft tissue and bone deficiencies around teeth and implants. He has also innovated many concepts and devices, which have been registered with dozens of patented and developed into products in clinical use in many countries.
Dr Zadeh directs the VISTA Institute for Therapeutic Innovations, an Academy of Osseointegration (AO) authorized training center. He maintains a private practice of periodontology and implant surgery in Southern California.

LECTURE
ORTHODONTICS AND GINGIVAL RECESSION: IS IT AN INEVITABLE TRADE-OFF?
Orthodontic therapy—particularly with Clear Aligner Therapy (CAT)—has become an integral part of interdisciplinary dentistry. It enables clinicians to optimize tooth positioning for improved esthetics, restorative access, and implant site development. However, the risk also exists that orthodontic movement can inadvertently cause periodontal harm, including root dehiscence, gingival recession, and marginal bone loss.
Modern digital workflows, including CBCT and intraoral scanning, now allow clinicians to visualize roots, bone, and soft tissue in three dimensions. Yet, AI-driven treatment planning often prioritizes alignment goals over periodontal health, leaving patients—especially those with thin gingival phenotypes—at risk for soft tissue complications.
This lecture presents a proactive, synergistic approach to orthodontic and periodontal care. By integrating CAT with the Vestibular Incision Subperiosteal Tunnel Access (VISTA) technique and phenotype modification, clinicians can preserve and enhance soft tissue architecture during orthodontic treatment. Practical protocols will be shared to guide clinicians in sequencing orthodontic, surgical, and restorative phases for optimal esthetic and functional outcomes.
OBJECTIVES: At the completion of the course, participants will be able to:
-
Learn the role of soft tissue phenotype modification in preserving periodontal health during orthodontic therapy
-
Identify pitfalls and complications associated with aligner therapy, including gingival recession
-
Develop clinical strategies for combining CAT and VISTA to minimize recession and enhance treatment predictability
