DISADVANTAGES; 1. Such an impression will not cover enough The mucostatic impression of the soft tissue areas, already taken, is inserted in the mouth (Fig. Various theories are: Definite-Pressure/ Muco-compressive theory. ... Concept of mucostatic was introduced Mucostatic theory (based on Pascal's law) sets out to record the mucosa in its static (supported by underlying basal bone), undisturbed form. Dental impression is an imprint or negative likeness of the teeth and/or edentulous area and adjacent tissue. A) Hand mixing. 4: Metallic stock tray chosen to cover the whole arch.The arrow indicates the site of finger pressure over the edentulous area. 5). To achieve this the impression of the arch should be made without any pressure exerting on it Minimal- pressure/ Mucostatic theory. Fig. ABSTRACT: Impression is basically an interaction between tissues and impression material. Zoe impression paste, polysulfide; iii) Vigorous mixing. Review of literature was done by Zinner and Sherman in1981 assuming that any important technique/theory of impression making published in dental journal is eventually published in a textbook.3 Analysis of history on complete denture impression making can be done era wise i.e. e.g. 3: Mucostatic impression of the edentulous areas. Impression compound – wet kneading, putty consistency Elastomers; ii) Circular motion (with glass slab & spatula) eg. Mucostatic impression records the soft tissues in their resting state, thus no or minimal pressure is applied during impression taking. Complete denture impression is a negative registration of the entire denture bearing, stabilizing and border seal areas of either the maxilla or Non-Pressure (Mucostatic) This theory uses the passive position of oral mucus membranes. Minimal- pressure/ Mucostatic theory. The impression is made with oversized or spaced trays with no border seal or border refining and very fluid impression material This type of impression covers only firmly attached mucosal This is possible only if the impression material is watery and virtually requires no pressure to place it against tissues. from. The variety of impression materials and the range of working characteristics of these materials, make possible the development of impression procedures best suited for specific conditions. This technique has the advantage of ensuring a close adaptation of the denture base to the entirety of the mucosa and hence enhancing retention. Impression of a tissue in a resting state prevents it from undesirable forces all over the day. Impression compound; ii) Mucostatic e.g. Impression plaster; V) Based on the manipulation. This is possible only if the impression material is watery and virtually requires no pressure to place it against tissues. e.g. Fig. The theories actually describe the amount of pressure required to record an impression that improves the accuracy & functions related to denture during different stages of the evolution of impression techniques. Impression Making for Complete Denture Impression generally is a negative likeness or copy in reverse of the surface of an object. In theory the mucostatic impression does just that, and with the possible exception of the treatment of the post dam ea, which, according to some, needs functnal placement, this impression theory certainly has something to offer.
