title: Defining the posterior palatal seal on a definitive impression for a maxillary complete denture by using a nonfluid wax addition technique.
abstract: The posterior palatal seal area is defined as the soft tissue area at or beyond the junction of the hard and soft palates on which pressure within physiologic limits can be applied by a removable complete denture to aid in its retention. The retention of the maxillary denture is affected by the extent and the design of the posterior palatal seal. This article discusses a method of defining the posterior palatal seal on a definitive impression for a maxillary complete denture by using microabrasion and a nonfluid wax addition technique.
