Abstract: In this paper various sufficient conditions are given for the maximality of an $R$-order in a finite-dimensional central simple $K$-algebra, where $R$ is a regular local ring whose quotient field is $K$. Stronger results are obtained when we assume the dimension of $R$ to be three. This work depends upon earlier results of this author [5] for regular local rings of dimension two, and the fundamental work of Auslander and Goldman [1] for dimension one.
