Abstract:
Polymerization shrinkage can result in poor denture fit. The aim of this study was to determine the accuracy of heat-polymerized acrylic bases on simulated edentulous metal ridges having simplified and standardized geometric configurations. Analysis of variance was used to explore the relationship between fit and ridge-slope/ridge-convergences. The outcome of that analysis revealed that the discrepancies between the base plates decreased significantly (p < 0.05) as both the ridge slope decreased and the anterior-sagital convergence increased. These geometric correlations can help clinicians to anticipate potential areas of sore spots on residual ridges when delivering complete dentures.

Teeth
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...

Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
