Using a Neelon technique (also called “brush-dip” or “salt-and- pepper” technique), flow conventional pattern resin into the impressions of the clasps on the surface of the Blu-Mousse index. This tooth was one of the retainers for a mandibular RPD. Take an alginate impression with the partial in place and remove impression from the mouth, keeping the partial in the impression. [9] , [10] In recent years, the shift from analog to digital impression taking has also been implemented into maxillofacial rehabilitation of oncology patients. Hindels noticed that his technique fulfills three definite requirements needed to ensure proper load distribution in extension saddle partial dentures [8]: Through a survey of regular periodic examinations of partial denture cases realized according to this technique, less post-insertion adjustments were needed and refitting because of ridge resorption was rare [9]. 2- Monteith B. The tray is selectively relieved and covers the edentulous areas up to the border tissue attachment including the retromolar pads [3, 8, 10, 11]. The tray is tested in the mouth for stability. 1.

Based on the theories of impression a) Mucocompressive or definite … Tissue /Tooth- tissue supported RPD can't be constructed on a master cast made from a single impression because occlusal forces must be equitably distributed to the abutments and tissues of the ridge. Both phases necessitate correct impression making. Copyright © 2020 Dental News. The different resiliency of these supporting tissues may lead to the instability of the prosthesis. 1983, St Louis, MO: Mosby, p.381-400. The tooth supported RPDs have an advantage of presence of a direct retainer whereas this is lacking in the prosthesis fabricated over distal extension bases. 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. His technique consisted of making a mucostatic impression of the edentulous ridges followed by a pick-up impression with digital compression of the first through holes prepared on the impression stock tray.
