The impression techniques Following are the different impression techniques that can be used for resorbed mandibular ridges: The functional impression technique. Impression mak-ing in total edentulism is … first impression stage. The liquid is very fluid, i.e. Impression techniques in use at the middle of the twentieth century vary not only in the plan of the technique, but with the use of the plan by each operator as well. Relating this to complete denture impression technique, we have been provided with a set of philosophies - "no pressure, minimal pressure, definite pressure and selective pressure". • 1950s elastomeric impression It is defined as a custom made device prepared for a particular patient which is used to confine and control an impression material making an impression. The admixed technique. 8 This method is based on the histological anatomy of the supporting tissues. A mucostatic impression technique using irreversible hydrocolloid served as control. This presentation will present a layering impression method utilizing several viscosities to accomplish both the functional and mucostatic properties required for proper removable prosthesis. The mobile tissue area will be recorded with a zinc oxide impression material (Krex). * Mucostatic impression technique, which aims to achieve support from the other firm areas of the arch and maximizes retention. • 1936 Alginate-type materials patent awarded. Impression techniques used were Applegate's functional fluid wax and a single-impression technique with mercaptan rubber. An individualized impression tray makes on the cast obtained from primary impression. * Mucodisplacive impression technique, with the aim of compressing the loose flabby tissue to allow functional support from it by replicating the contour of the ridge during compression by occlusal forces. Complete denture fabrication in clinically compromised situations such as flabby ridges is a challenging task for the clinician. The method will describe a one appointment procedure delivering superior detail of both hard and soft tissues. This article discusses the basic principles of nonpressure mucostatic and selective-pressure functional impression concepts and provides a theoretical and scientific basis for the design of a CD base. Tray adhesive was applied. 5: The mucostatic impression with the occlusal rims in place. Impression making is an essential step in the fabrication of complete dentures. mucostatic, and, being a water-based system, readily adapts to the soft tissues. Accurate impressioning of these tissues plays a major role in ensuring a well-fitting prosthesis. Mix the Zinc Oxide (Krex) impression material and apply it over the mobile tissue with a small brush or syringe. This advocates the selective pressure impression technique and provides dentists with good evidence for the clinical procedure. Publication types Review MeSH terms Dental Impression Technique* Denture Bases* Denture, Complete* (b) Altered-cast impression for the distal-extension RPD. MUCOSTATIC IMPRESSION TECHNIQUE • Also known as minimal pressure impressions. After the face-bow transfer, the maxillary and mandibular master casts were mounted in centric relation on a (a) (a) (b) (b) (c) (c) Figure 3.: (a) Maxillary impression prepared by mucostatic impression technique. PMID: 398820 [Indexed for MEDLINE] MeSH terms. In this report, a technique is presented in which conventional impressio … Two part impression technique or Mucostatic and mucodisplacive combination or window technique was first described by Osborne in 1964. The selective pressure impression technique combines aspects of both mucostatic and functional impression techniques. A mucostatic impression technique using … Fig. • 1940s first alginate impression. Four basic impression philosophies proposed over years for impression making are: mucostatic, mucocompressive, minimal pressure, and selective-pressure impressions [1-4]. Functional impression can be used very effectively to create stability in cases exhibiting extreme resorption. 2). Fig. 4: Metallic stock tray chosen to cover the whole arch. Mucostatic theory follows the impression being taken of the mucosa when in its normal resting position. The arrow indicates the site of finger pressure over the edentulous area. ...
