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.
后腭封闭区被定义为硬腭与软腭交界处或其后方的软组织区域，可摘全口义齿可在该区域施加生理限度内的压力以辅助固位。上颌义齿的固位受后腭封闭的范围和设计影响。本文讨论一种通过微磨除和非流体蜡添加技术在确定性印模上确定上颌全口义齿后腭封闭的方法。
