Senior Lecturer in Dental Technology
Biography
Dr Mike Cattell is a lecturer in the Centre of Adult Oral Health, at Bart’s and the London, School of Medicine and Dentistry, UK. In 1994 he was awarded an MSc in Dental ceramics and worked in conjunction with the Department of Biomaterials and the Department of 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 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. Dr Cattell teaches undergraduate and postgraduate dental students and is course mentor for Foundation Degree student Dental Technicians. He supervises MSc and PhD students in the faculties of both Dentistry and Materials and is course director for the MSc in Dental Technology. He was awarded the Certificate in Learning and teaching (2007) and is an Associate of the Higher Education Academy. He is a reviewer for several Dental and Scientific Journals including: Dental Materials, Materials letters, Materials Research bulletin, Biomedical Materials Research and the Journal of Dentistry. Dr Cattell is also a consultant for industrial companies and has supervised several industrial projects.

Research interests:
The nucleation and crystallisation of novel glasses and leucite glass-ceramics for Dentistry and processing techniques to enhance their mechanical properties are Dr Cattell’s main research areas. Work has been carried out to develop new leucite glass-ceramics as low wear/high strength materials for all ceramic dental restorations, with heat extrusion as a method of restoration manufacture. Etchable glaze coatings for dental prostheses to improve mechanical properties have similarly been explored. Other areas of work are the mechanical testing of ceramic materials and the application of Statistical analyses (Weibull and Gaussian) to describe the distribution of flaws in brittle materials and the material survivability. Fatigue and fracture testing of all ceramic dental restorations in a simulated oral environment has also been investigated.
His initial research on leucite glass-ceramics led to a patent and the commercialisation of a leucite glass-ceramic and an etchable glaze material, as Restorative Dental materials. 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). In 2008/2009 he has published two patents for higher strength (nano-scale) and low wear leucite glass-ceramics in conjunction with industry which should be shortly on the market. Dr Cattell is presently working on glass-ceramics with unique microstructures and mechanical properties which have never been demonstrated in this category of materials. This work is in collaboration with Professor Robert Hill, a world leader in this field and member of the prestigious Technical Committee (IGC, TC7) on Nucleation, Crystallisation and Glass-Ceramics.
