The occlusal surface of the denture is pressed into the putty sufficiently deeply to produce firm retention.
The occlusal surface of the denture can be similarly displayed, following an imprint of the intaglio surface in the lid of the box if it has sufficient depth (Fig. 7).
Almost no region has shown negative deviation, since the actual surface of the denture base cannot invade the surface of the cast model.
Dab three or four pea-sized amounts of adhesive to the tissue surface of the denture, then insert.
Samples consisted of supragingival dental plaque pooled from at least two remaining teeth, or if the patient was edentulous, from the buccal mucosa, or, if they were wearing a denture, from the tissue surface of the maxillary denture.
Previous studies showed that the analysis of the capacity of denture biofilm removal was based on the internal surface of the complete denture that this surface has greater potential for collection of pathogenic microorganisms [ 7, 35, 36].
The average deviations between the tissue surface of the wax denture and the plaster cast were listed in Table 1.
Using the multipoint registration and best fit alignment command, "DataWaxRP" was registered to "DataModel&WaxRP" and "DataWaxManual" to "DataModel&WaxManual," where the polished surface of the wax denture was set as the common area.
Deviation between the tissue surface of the wax denture and the plaster cast was shown in Figure 2, the green area represents a good fit between them, yellow and red areas indicate a positive deviation (tissue surface locating above the cast surface), and the blue area indicates the presence of a negative deviation (tissue surface locating below the cast surface).
Also, the surface topography of the denture has been shown to greatly influence adhesion and subsequent retention, with more roughened surfaces retaining more organisms [ 17– 17].
