Prof. dr. M.A.J. van Waas, DDS, Ph.D., nick name Rien (09-22-1946).

He studied dentistry at the dental school of the University of Utrecht in the Netherlands, where he in 1985 received his doctor’s degree with a thesis titled: “Een kunstgebit, een kwestie van doorbijten” (Artificial teeth, a question of ‘grinning and bearing’).

From 1985 till 1995 he worked in the Department of Oral Function of the University of Nijmegen, doing research in the field of complete (over)dentures, shortened dental arches, oral implantology and geriatric dentistry.

In 1995 he became a Full Professor at the ACTA (Academic Centre for Dentistry in Amsterdam), enabling him to function as a lecturer as well as a researcher in the field of Prosthodontics and Oral Implantology.

During the years he published together with his colleagues around 80 articles in English and a little more in Dutch.

He retired in 2009, but is still lecturing in complete and partial dentures with and without implants, in treatment strategies in patients with reduced dentitions (crowns and bridges on natural teeth and implants) and in geriatric dentistry.

As a living creature on earth, he tried to understand the incentives and the behavior of human beings. For this reason he is going into astronomy, geology, quantum mechanics and the evolution of life on earth, and with my scientific background I am concerned with scientific integrity and ‘bad science’.
