The Caerphilly-born loose head, who has come through the Dragons Academy set-up, has represented Wales at both Under 16 and Under 20 level.
"The Dragons view Aaron as one of the stars of the future," said Dragons' Rugby Manager Robert Beale. "We plan to withdraw him from competitive rugby after the World Cup for several months and concentrate on strength and conditioning, which should enable him to compete at the highest level.
"Aaron has been earmarked as part of our next generation of front row players and we intend to invest as much expertise and resources into his as we can."
