No eccentric adjustments are made to the occlusion prior to the clinic remount, as it is impossible to obtain totally accurate records of jaw relationships with base plates and wax rims or teeth set in wax.

Since the casts are moist and sticky wax will not stick to wet casts, retention cuts are made on the proximal surfaces of both the casts and their plaster mountings (Figure25.6).

Remount the complete den-tures by adding sticky wax around the entire periphery of the mounting and cast (Figure25.7).25.3 Adjusting theOcclusion1) Check the guide pin for an increase of vertical dimen-sion, which is expected and is termed “processing error” (Figure 25.8). 2) Wax elimination.

Flasking, Packing, andProcessing Complete Dentures 149After the flask is sufficiently cool to the touch, the flask lid is removed by wedging an instrument such as a Buffalo knife or chisel in the notch (Figure24.41) that is provided on the flat end of the flask. Since the early 19th century, the construction of complete dentures has involved a lost-wax/investment technique with teeth set in a wax-trial denture, then encompassed by an investment material, with the wax ultimately replaced by a definitive denture base material. Do not use heavier articulating paper because it will record areas that are not in intimate contact. Start with medium pumice followed by fine flour of pumice until all scratches are removed. Uploaded by stone adhere to the surface of the denture: causes : - the application of separating medium contimated with stone. in complete closure of flask. You may use rubber bands or place a heavy weight on top of the upper member of the articulator to hold the guide pin tightly against the guide table.

Making aRemount Index 157Figure 26.8 Print the patient’s name on the index with a permanent marker.Figure 26.7 The remount platform has two or three distinct depressions on its surface which produce an index. Treating the Complete Denture Patient160Figure 27.1 Remove the cast from the denture in small sections one piece at a time.Figure 27.2 Trim off all flash from the peripheral borders of the dentures with a laboratory acrylic bur.Figure 27.3 Use an arbor band to quickly remove large amounts of flash.Figure 27.4 Take care not to overreduce buccal, facial, and lingual fold contours.Figures 27.5 and 27.6 Take care not to reduce or overpolish gingival festooning around the teeth. Treating the Complete Denture Patient154Figure 25.11 Avoid reducing any cusp tips.Figure 25.12 Once the pin touches the guide table, make no further adjustments during the lab remount.Figure 25.13 With a monoplane denture set in zero-degree teeth, flat-surface the maxillary denture’s occlusal plane with a piece of sandpaper resting on a flat surface. # A complete denture patient complains that he has pain in his throat during swallowing. Complete Denture Processing - Flasking . Therefore, only the occlusion is adjusted in centric relation in a laboratory remount to correct the changes in vertical dimension of occlusion due to processing error.If it is a zero‐degree monoplane denture, the occlusion of the maxillary denture’s occlusal plane is flat‐surfaced with a piece of sandpaper on a flat surface (Figure 25.13). Flasking is the process of investing the cast with the waxed denture in a flask to make a sectional mold that is used to form the acrylic resin denture base. Packing and Processing. The procedure for making a complete denture is as follows: Emergency treatement. Allow the plaster to harden. Small bubbles between the teeth may be easily removed by the point of a green‐handled knife (Figure27.7).1) Inspect the tissue side of the dentures for small blebs due to voids in the casts.

Flasking, Processing, and Finishing Removable Partial Dentures, Figure 7 The flask is assembled and the second pour of stone is made. Print the patient’s name on the index with a permanent marker to identify it and store it in a safe place for future use (Figure26.8).26Making aRemount Index 1. Errors of flasking: Tooth movement: causes: - the use of plaster instead of stone. 13 th ed. Since there are no cusps on zero‐degree teeth, the only occlusal reduction made on a denture with zero‐degree teeth is that the occlusal surfaces of the maxillary denture teeth are made flat using a flat piece of sand paper resting on a flat surface. Clean the bases of the casts and the surfaces they con-tact on the plaster mountings by brushing them with a soft toothbrush to ensure they are clean prior to mount-ing the casts on the articulator. 1. This would result in unnecessary and undesirable reduction of surfaces that will need to be preserved. Note that the basal seat surfaces are not altered or shined. Very well‐defined grooves which have been cut in the bases of the casts before their initial mounting will ensure that there is an accurate and stable fit between the casts and their mountings.
