The denture is then positioned on the model and the new saddle areas are poured. The denture is then positioned on the model and the new saddle areas are poured.
Case Description The article describes a patient who had a unilateral distal extension removable partial denture that was fabricated after the failure of a year-old partial denture due to extensive dental decay. An altered cast procedure to improve tissue support for removable partial denture.
Denture construction then continues as normal. Case Report A female patient aged about 50 years came with the complaint of missing upper and lower teeth. A well-made removable partial denture that has appropriate extensions, borders and ridge-to-dentition relationship will benefit the partially edentulous patient by providing increased comfort and improved dental function.
The metal framework was constructed on a cast produced by a mucostatic impression material. The distribution of loading of the free-end saddles is improved and denture is more stable.

The patient presented with missing 13,15,16, 24, 27, 36, 37, 46, 47 and mandibular anterior 4 unit fixed partial denture [Figure 1] and [Figure 2]. The metal framework was constructed on a cast produced by a mucostatic impression material.
Literature Reviewed This article reviews research that evaluated abutment tooth movement as a result of the relationship of the denture base to the residual ridge, revealing that improved fit reduced tooth movement.
The result is a potentially more stable RPD that improves the support for the occlusal relationship of the opposing dentition and the RPD restoration. All of which lead to increased patient satisfaction. The altered cast technique is employed to try and prevent this by making an impression of the mucosa under controlled pressure.
Contemp Clin Dent ;1: The resulting model represents the free-end saddle areas under conditions, which mimic functional load. Border molding was carried out; impression was made with zinc oxide eugenol impression paste.
This presentation describes the original concept of the altered cast impression technique as described by Applegate  review studies of the technique and the clinical and laboratory phases required for distal extension RPD fabrication.
All of which lead to increased patient satisfaction. Base plates were then constructed in self-cured acrylics on the framework in the saddle areas, and these are close fitting.
However, this technique has the potential benefits of reducing the number of postoperative visits, preserving the residual ridges, improving stress distribution, decreasing food impaction and decreasing the torquing of abutment teeth.

NB may need soft tissue support as well if large span, one rest can support missing teeth in general Altered cast technique. Cast partial denture made using the altered cast impression technique helps create an environment in which the teeth and the edentulous tissues support the base as compatibly as possible.
The result is a potentially more stable RPD that improves the support for the occlusal relationship of the opposing dentition and the RPD restoration. Author: dmurphy7 [ B ] Created Date: 7/30/ AM.
The result is a potentially more stable RPD that improves the support for the occlusal relationship of the opposing dentition and the RPD restoration.2 The altered cast impression technique is relatively simple to incorporate in the fabrication of the RPD.
The altered cast technique allows the ridge, recorded in functional form, to be related to the teeth so that when the prosthesis is seated, it derives support simultaneously from the teeth and the denture base. Altered cast impression technique is commonly used for the mandibular distal extension partially dentulous arches.
The technique is relatively simple but requires increased chair-side time and.Download
