Abstract:
This study aimed to evaluate the mechanical behavior of a removable partial denture (RPD) using a new technique of impression-the combined impression technique (CIT)-via three-dimensional finite element analysis (FEA). A patient was selected to have removable partial dentures fabricated using CIT and the open-mouth impression technique (OIT), and the results were compared through FEA. Compared to OIT, CIT resulted in lower von Mises stresses on abutment teeth and alveolar ridges, with no significant stress concentrations and more balanced mucosal displacement in edentulous areas. CIT proved promising as it presented more favorable results than OIT in this simulation.

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...

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.
