Profile

Dr Mike Cattell is a Reader in Dental Technology and Biomaterials, at Bart's and the London, School of Medicine and Dentistry. In 1994 he was awarded an MSc in Dental ceramics and worked in conjunction with the Department of Biomaterials/ Materials at Queen Mary (QM) and published extensively within the Dental Biomaterials field. He then went on to work in conjunction with the Interdisciplinary Research Centre in Biomedical Materials (QM) and the Department of Biomaterials and Tissue engineering at the Eastman Dental Institute and gained his PhD in 2003. This work included the synthesis and heat extrusion processing of novel leucite glass-ceramics and led to the patenting and commercialisation of a leucite glass-ceramic as a restorative dental material.

He was previously a Senior Chief Dental Technician in Restorative Dental Technology with over twenty-five years’ experience and was awarded the TEC Diploma in Dental Technology and Sherring Lucas award prize (1984), and later an advanced Certificate in fixed Prosthodontics as his specialisation (1986). Managing a busy conservation laboratory and teaching has given him a vast technical knowledge/experience in a wide range of manufacturing techniques used in dental restoration construction, together with knowledge of functional dental occlusion, dental anatomy and the aesthetics of restorations. He was awarded the Certificate in Learning and teaching (2007) and is an Associate of the Higher Education Academy.


In 2012 Mike was a games maker and Lead responsible for setting up and running the Dental Laboratories for the Olympic and Paralympic games, providing all Dental prosthesis requirements for athletes, including a successful mouth guard programme. He was part of the Olympic and Paralympic games medical team who won the prestigious Nursing Times Team of the year award.
Dr Cattell teaches both undergraduate and postgraduate dental students and supervises MSc and PhD students in the faculties of both Dentistry and Materials. He is course director for the MSc in Dental Technology and a reviewer for several Dental and Scientific Journals including: Dental Materials Journal, Journal of Dentistry, European journal of Prosthodontics and restorative dentistry, British Dental Journal, Journal of the European Ceramic Society, Advances in Applied Ceramics: Structural, Functional and Bioceramics, Ceramic bulletin). He is on the board of the European Dental Materials society and is an International and National External examiner. Dr Cattell is also a consultant for industrial companies and has supervised several industrial projects. His research students has won numerous prices including: Drapers prize, Voco prize for Dental Biomaterials (IADR), Kulzer travel award (IADR).

Research

Research Interests:

Main research interests are the synthesis, nucleation and crystallization of novel glasses for Dentistry. This work led to novel low-wear, high-strength nano-scale glass-ceramics to prevent facture and wear of dental ceramic restorations and several patents and publications. Over three million restorations were provided for patients and sold in 46 countries for one glass-ceramic formulation, generating significant industry and general dental practice profits. The leucite glass-ceramic product was clinically rated excellent by the 'Dental Advisor' and also by the Clinical Research Associates (CRA), who evaluate products for the dental profession. The Leucite glass-ceramic (Lumineers®) was also awarded top cosmetic product by the 'Dental Advisor' (2008). The product uses a 100% pain-free minimally invasive approach, saving as much as 20% enamel reduction per patient, as tooth preparation and anaesthesia are not required. We also estimate a substantial reduction in tooth enamel wear. It has high patient acceptance and satisfaction, and has received media coverage worldwide. The research work behind this material also won the Voco prize for Dental Biomaterials research at the International Association of Dental Research meeting. According to the 2014 REF the impact arising from this work was judged to be excellent in terms of reach and significance.
Dr Cattell is presently working on glass-ceramics with unique microstructures and mechanical properties which have never been demonstrated in this category of materials. Other ceramic research areas are the development and testing of Diopside, Nephalene, lithium disilicate glass-ceramics, YTZP ceramics and glaze coatings for dental restorations to enhance their mechanical properties and adhesive bonding. Processing ceramics using novel plasma spark sintering, electro spinning of fibers and layer by layer drug encapsulation are newer research areas. Projects have collaborated with Industry, the Eastman’s Dental Institute, School of Engineering and Material Science (SEMS, QM) and Nanoforce (QM).
