Oral Design – The Aesthetic Philosophy of Natural Beauty

Chief Director Dr. Jaewon Seo of TU Dental Clinic is an official member dentist who shares the philosophy of Oral Design.

The standard for designing life, beyond the oral cavity.

An International Dental Aesthetic Research Groupin the Field of Dental Aesthetic Prosthetics

Oral Design is an international dental aesthetic philosophy and research group that views teeth as a design element, considering facial balance, expressions, and overall atmosphere. Founded in 1982 by the world-renowned dental aesthetic maestro Willi Geller, it has been expanding the standards of natural smiles and dental aesthetics for over 40 years, based on the collaboration between dentists and ceramists.

We do not consider the oral cavity to be merely the inside of the mouth,
but believe that every oral cavity forms its own individual face and mouth.
We believe that every oral design case is the ultimate custom-made case,
and we seek the best design for each patient's mouth to build a better relationship
between the person and the prosthetic.

Maestro Ceramist

Maestro Ceramist Willi Geller

Willi Geller, known as the father of modern aesthetic dentistry, is a legendary ceramist who founded Oral Design in 1982 and is a respected artist for his artistic vision and delicate expression. By applying artistic sensibility to the field of aesthetic dentistry, which previously focused on technology, he is highly renowned for leading leap-forward developments by presenting new perspectives and concepts that upgraded both technology and beauty.

Oral Design Philosophy

The Beginning of All Standards

The philosophy of Oral Design began in 1982 with Maestro Ceramist Willi Geller. He is the figure who established the concept of a ‘Designed Smile’ by introducing an artistic vision to the technology-centered field of aesthetic dentistry. This standard remains at the heart of Oral Design today.
