She finished Petar Preradović elementary school and grammar school in Zadar, and graduated in 1995 from the School of Dental Medicine, Zagreb.
She is especially dedicated to working with children and with children with special needs, and in the field of aesthetic dental medicine. She achieves excellent results in laser therapy of gum tissue, specialising in that area through numerous dental courses. Laser dentistry is the most advanced dentistry field, and Dr. Ivona Dijan Fabijan practices it daily in her work.
Besides aesthetic dental medicine, she also works with fillers. She is thus able to not just enhance the inner part of oral cavity, but the outer oral area as well (nasolabial fold, mentolabial fold, cheeks, lid area...).
