Professor of Prosthodontics & Oral Rehabilitation

Background

Introduction

Following a period of Acting Head from January 2016, I was appointed Head, School of Dental Sciences in August 2016.  Prior to this I had been Director of Dental Education and Degree Programme Directorfor the previous 7 years.  My current publications are largely based in the area of Dental Education but also link with my clinical research which has focused on the assessment of factors that influence patient acceptance of prostheses. Through a series of RCTs and qualitative studies with edentulous subjects using impact supported prostheses we have established and quantified substantial improvements in Patient Satisfaction, Quality of Life.  This has supported a new international Standard of Care for this patient group which is embodied in the York Consensus Statement 2009 and supports offering this treatment as a minimum standard of care for this patient group. This outcome reflects contemporary clinical findings published since my contribution to the McGill Consensus Statement 2002 & was developed during my Presidency of the British Society of Prosthodontics

    Research Interests

    Efficacy of Treatment in Prosthodontics

    Clinical Research in Prosthodontics has focused on the assessment of factors that influence patient acceptance of prostheses. A unique prospective RCT compared the use of bilateral cantilever adhesive bridges with conventional partial dentures. Nutrition and dietary invalidity were investigated as part of these projects (Regional NHS funding). This theme was developed and supported a PhD studenship to test the value of customised dietary intervention and investigate barriers to dietary change.

    Professor Thomason has expanded this research grouping to investigate the effect of dental implant provision on health related quality of life. The research profile comprise a series of randomised controlled trials examinging implant supported prostheses in edentulous patients and is supported by a programme of Qualitative Research Projects based in the UK and shared with our Research Collaborators in the Faculty of Dentistry, McGill University, Montreal, Canada. An integral strand of this work includes the impact of this form of treatment on food choice and nutritional status. Research funding is maintained by a series of industrial partners, research charities, and Research Councils, including the Medical Research Council and the Canadian Institute of Health Research.

    Professor Thomason spent part of 2002 as Visiting Professor at McGill University, building on links developed with Prof Feine their Director of Clinical Studies. The McGill Faculty has an international reputation in patient based outcomes for implant treatment. He was appointed Adjunct Professor in the Faculty of Dentistry at McGill at the end of 2002 a post which he maintains through his work at McGill each year. A signatory of the McGill Consensus Statement, Professor Thomason has developed a strong collaboration with Professor Feine and other members of the McGill Faculty and is currently overseeing a series of projects in Canada.

    Oral Health in the Medically Compromised

    Funding from the Arthritis Research Campaign (ARC) has supported a 3 year investigation of the oral health of children and young adults with juvenile chronic arthritis (JIA) undertaken as a multidisciplinary project with the School of Medical Sciences (Rheumatology) supporting an MPhil student. The recently awarded Shirley Glasstone Hughes Research Award has underpinned investigations of the relationship between periodontal disease and cardiovascular diseases.

    Drug-Induced Gingival Overgrowth in Organ Transplant Patients

    Professor Thomason completed his PhD in the field of drug-induced gingival overgrowth in organ transplant patients and now lead a team comprising colleagues both in the School and Faculty which has built on the close liaisons established with the Regional Cardiac and Renal Transplant Centres. The principle theme of the work is the investigation of the aetiology and management of the dental problems that arise in organ transplant patients. The major clinical risk factors for drug-induced gingival overgrowth have been identified and described. At the cellular level, differences detected in the distribution of matrix metalloproteinases (MMPs) in patients with overgrowth have highlighted mechanisms for the shift in tissue homeostasis seen in this condition. The investigations have focused on the role matrix metalloproteinases (MMPs) and their natural inhibitors (TIMPs) and builds on previous work on TGF-ß and MMPs in gingival overgrowth, and the effects of cytokines on collagen turnover in cartilage and synovial tissue. These studies have supported a series of PhD and MPhil studentships).
    The clinical programme investigating both surgical and non-surgical therapies (comparison of different conventional surgery techniques and the use of laser surgery as well as the use of a sonic toothbrush in the control of post surgical regrowth) benefited from industrial funding and currently provides the clinical base for the clinical postgraduate research projects. Finding that steroid cover is not required for these patients during surgery has fundamentally changed the clinical management of this group of patient. The work with organ transplant patients has been recognised by the Oral and Dental Research Trust and the British Society of Periodontology.
