Aston attends the Kois Education Center, widely regarded as the global standard of continuing dental education, being the only education centre in the USA conducting and publishing independent research.
He is also a Graduate of the Kois Center, based in Seattle – of which only a handful have attained this 9-step level of training within the UK and Aston is the only one in Wales.
Aston is the first cohort of dentists in the UK to have undertaken a post graduate certificate in Dental Airway Management allowing treatment as part of a medical multidisciplinary team approach to treat sleep disordered breathing, linking strongly to his full mouth treatment rehabilitations.
He takes referrals for prosthetics (dentures and implants) and complex tooth wear management and has lectured nationally on the topic. He has recently accepted a role lecturing in the University Hospital Llandough to the Dental Foundation dentists.
