J Prosthet Dent, 1960;10:112-123. This maneuver permits to relate the edentulous ridge to the residual teeth in a functional state. Distal extension removable partial denture (RPD) depends largely on the residual alveolar ridge for support, stability and retention. This article reviews various impression techniques that aim to equalize the masticatory load between teeth and edentulous areas thus enhancing the stability of partial denture during function and preserving the residual oral structures. The individual tray is loaded with zinc oxide-eugenol impression paste (Cavex Outline by Cavex Holland BV) and brought to position without any compression while the soft tissues are left in their passive state (Fig. Instructor, Dpt of Removable Prosthodontics School of Dentistry, Lebanese University, Beirut, Lebanon. Accurate impressioning of these tissues plays a major role in ensuring a well-fitting prosthesis. Functional impression tech. In tooth- and tissue-supported RPD, we included trials comparing the same material and different dual-impression techniques, and different materials with different dual-impression techniques. The tissue surface of the saddle is a negative reproduction of the anatomic, undistorted surface of the alveolar mucosa.

The mucostatic impression of the soft tissue areas, already taken, is inserted in the mouth (Fig. J Prosthet Dent 2001;85(4). Care is taken so that the height of the occlusal rims surpasses the height of the residual teeth in order to ensure a positive and sole contact between the occlusal rims and the impression stock tray later on during the pick-up impression phase (Fig. Fig. Make a preliminary impression and models. 28 (Figure 1).

The construction of a removable partial denture in distal extension cases is a delicate procedure since the prosthesis is supported by two different tissues, namely teeth and mucosa. Christensen 26 has described a closed-mouth impression technique using a high-viscosity impression material to facilitate an indirect RPD reline that yielded a near optimal fit.

[9] , [10] In recent years, the shift from analog to digital impression taking has also been implemented into maxillofacial rehabilitation of oncology patients. INTRODUCTION An impression is defined as a negative likeness of the teeth and/or edentulous areas where the teeth have been removed, made in a plastic material which becomes relatively hard while in contact with these tissues 5). Initially, when an impression is made to establish a relationship between the teeth and the mucosa in a displaced state, a perforated tray has to be provided with two circular openings to exert a pressure on the acrylic tray on the molar regions.
