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. A remount index is then made to preserve the facebow record; other-wise a new facebow record must be done during the inser-tion appointment.

Remove this carefully with a discoid or other small instrument and a mounted rub-ber point (Figure 27.10) but do not overpolish acrylic denture teeth.3) Finish the external surface and peripheral fold with rubber points to remove gross defects and impart the final contour. 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). When a complete denture is applied to only one of the jaws in the mouth, it is called a SCD. Start studying Flasking, Packing and Processing Complete Dentures.

Purpose: The purpose of this study was to compare the artificial tooth positional changes following the flasking and polymerization of complete dentures by a combination of two flasking methods and two polymerization techniques using computer graphic The most common fault is an increase in vertical dimension which leaves the incisal guide pin open or not touching the incisal guide table due to the slight excess of acrylic in the flask. Flasking ,Wax elimination. 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. Use the broad, flat surface of the mallet to remove the invested den-ture from the flask. Use coarse abrasives and burs first, if needed for gross reduction. The pro-cessed denture base containing the teeth should be recov-ered intact and still attached to the stone master cast. WHAT IS FLASKING? It shows up as a gap between the guide pin and the incisal guide table. Now that the dentures have been flasked, the wax must be eliminated to form a mold into which resin may be packed.

This is the only correc-tion done during the lab remount. If the flask was properly lubricated prior to the investing, removal should not be a problem as the invested denture should come out clean (Figure24.44).

Importance The form of the polished surfaces and the proper location of the artificial teeth play a major role in Stability of the dentures Influences its retentive quality. An occlusal error of up to 0.75 mm is acceptable and can be corrected by occlusal alteration of the teeth.Figures 24.45 and 24.46 Use a plaster saw or chisel to remove all plaster until the denture is exposed.Figure 24.47 If the denture detaches from the cast, clean the cast and the mounting carefully and allow them to dry. An air chisel, plastic shears, and/or nippers can be used to chip the plaster from around the periphery of the stone cast until the base is exposed. Their recognition and acceptance in prosthodontics are indeed incredible as they are found to be easy to A sanding sponge must not be used for this procedure because it is soft and incapable of developing a flat surface on the denture teeth.2) Ensure the greatest accuracy in marking the articular surfaces of the teeth by using one thickness of double‐sided articulating tape (AccuFilm®) (Figure 25.9).

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. 1. space between the teeth and resin base. Errors of flasking: Tooth movement: causes: - the use of plaster instead of stone. It is important to note that during the lab remount procedure, processing error is the only correction that is made.With the condyles locked in centric relation, deepen the marks in the fossae with the end of a laboratory acrylic bur (Figures25.10 and 25.11).

A complete denture (also known as a full denture, false teeth or plate) is a removable appliance used when all teeth within a jaw have been lost and need to be prosthetically replaced.In contrast to a partial denture, a complete denture is constructed when there are no more teeth left in an arch, hence it is an exclusively tissue-supported prosthesis. Treating the Complete Denture Patient, First Edition. The denture is secured to the cast with sticky wax.The flasking, packing, and processing of a complete den-ture can produce some distortion from the original waxed‐up form. Lubricate the teeth with petroleum jelly (Figure 26.2).

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. 7) Shaping and Polishing Flask: Is a metal tube used in investing procedures. The denture is placed in a bowl of water while the cast and mounting dry. Lock the maxillary member in its most forward position using the condylar thumbscrews (Figure25.3).2) Set the lateral guidance at 15° using the large set‐screw on top (Figure25.4).
