What is a denture post dam?
Medical Definition of postdam : a posterior extension of a full denture to accomplish a complete seal between denture and tissues.
What is the function of post dam?
A groove cut along the posterior palatal margin of a denture cast which produces a ridge on the finished denture and forms a more effective posterior seal to aid retention. It also acts to prevent food debris collecting between the palatal mucosa and the denture.
What is post dam area?
Post Dam Area: It is the area between anterior and posterior vibrating line. extends medially from one tuberosity to the other.
What does the post dam provide on a maxillary denture?
The laboratory relining/rebasing of a maxillary complete denture (CD) requires a uniform reduction in the intaglio surface of denture base. This procedure provides a space for impression material and a new layer of acrylic resin.
What is denture flange?
Denture Flange In Complete Denture the extensions of the denture on both lingual and buccal sides are known as Denture Flanges. These should be present for providing the proper peripheral seal to the denture which is the main factor for the stability of Complete Denture.
What is peripheral seal?
1. The fit around the outer margins of a denture that creates an effective contact between the denture and the soft tissues and improves retention. 2. The peripheral contact between a restoration and the prepared tooth tissue; also sometimes referred to as a border seal.
What is posterior palatal seal?
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.
