Professor Michael Braden, BSc, PhD, FIM

Emeritus Professor


BSc (Lond),1957; PhD (Lond) 1962.
British Rubber Producers Research Association, 1951-1961. Most significant research- establishing the mechanism of ozone degradation of diene elastomers.
Appointed Lecturer in Dental Materials Science at the London Hospital Medical College 1961, in the Department of Prosthetic Dentistry, both to introduce a stronger scientific basis to the undergraduate teaching of dental students, and to initiate research. Promoted to Senior Lecturer 1963, and appointed Reader in 1968 by conferment of title. Appointed Professor of Biomaterials in Dentistry by Conferment of Title in 1973, with the formation of the Department of Biomaterials in Dentistry. The chair was established in 1992.

In 1990, was co-applicant with Professor W Bonfield CBE FRS(Director), the late Professor Denis Chapman, and Professor George Bentley for an Interdisciplinary Research Centre in Biomedical Materials, involving Queen Mary College, the London Hospital Medical College, the Royal Free Medical College, and the Institute of Orthopaedics. I was an Associate  Director i/c the Dental Programme, and Project Coordinator for the Optimised Bone Cement Project. After Professor Chapman's retirement I was also Deputy  Director.
The IRC was funded for 10 years, with Reviews at the end of two and five years.
Distinguished Scientist Award of the International Association for Dental research (Wilmer Souder Award) 1993. Gold Medal of  the British Society for the Study of Prosthetic Dentistry !993-the only non-clinical holder of this medal
Selected Invited Lectureships
Distinguished Lecturer Universities of Toronto, Mc Master,  Kingston, Canada 1992

Research Interests:

On entering the Dental Materials field in 1961, perusal of text books and papers being published on the subject, I was struck as a  polymer scientist at the general primitive state of the scientific aspects. Therefore my early work was  aimed at investigating clinically relevant  areas from a scientific perspective. Thus publications 1-5 introduced  fracture mechanics, heat transfer, diffusion, rheology, visco[-elasticity in characterizing properties of dental materials. 6-8 introduced analyzing the composition and structure of materials, together with their chemistry of function. This in turn lead to the development of new clinical materials, and the expansion of the work into orthopaedic surgery(9), and  drug delivery systems. (10).
(9) lead to a new bone cement which had limited clinical trials lasting some 15 years. Furthermore  the reputation thus earned led  to our being asked to develop  new orthodox bone cements for an orthopaedic company, which have been on the market for some years.
Clearly with some 200 publications over the years, selection is difficult. The development of these areas has lead to collaboration with other centres, both in the UK and overseas, including joint work with clinicians.
The principles of fundamental studies allied with the development of new clinical materials has continued over the intervening years, and are mirrored in the current list of publications, both by myself, and colleagues.
