The goal of the FC technique is to ensure uniform equilibration of support for the denture by loading the entire stress-bearing area. There are numerous techniques for the capture of final impressions in the edentulous arch to be considered.4,5 In theauthor’s experience, the most accurate is the functional impression. This technique requires only one step and, in most cases, uses a single impression material. For this purpose, impressions must record the soft tissue supporting areas simultaneously with accurate registration of the implant components. complete impression using the one-step technique with alginate. The technique aimed at creating an extremely accurate impression of undisturbed and uncompressed tissues. Prosthodontic application for implant carriers. Three types of impression techniques have been described in the literature.3 A single-stage impression procedure is commonly used with an open or closed tray technique.4,5 A double-impression technique for overdentures retained by only 2 implants has been suggested, using a zinc oxide eugenol (ZOE) impression paste and polyether impression material.6 The third type of impression technique is a functional impression technique for implant-retained overdentures.3,7 All of these techniques require operator finger pressure. Y1 - 2010/4. The tray is positioned in the mouth and pressed over the dental arch. For implant-retained overdentures to be successful, functional loads must be distributed optimally to the mucosa and the abutments. After setting, the fluid material usually gains an elastic consistency. • It is the shape of the ridge before functional load is applied. The custom tray technique is a particular variation of the two-step technique that involves the participation of the dental lab. They can be used in almost any clinical situation and, because of the detailed information, complete dental impressions are widely preferred by dental practitioners. Also, an implant-retained overdenture has characteristics resembling those of a complete denture with a combination of tissue support and implant retention.6 Thus, the resilience difference between implant and mucosa should be considered for the impression of implant tissue–retained overdentures.3 Therefore, the impression technique must provide an accurate resilience difference between implant and mucosa. The impression fidelity is not as high as in the case of the two-step or individual tray techniques but it is easier and faster to make. Note: The name of the techniques may vary from region to region. The impression of the opposite arch: these are the teeth opposite to the designed restoration. Gerodontology.
