Stress Distribution Pattern in Mini Dental Implant-Assisted RPD with Different Clasp Designs: 3D Finite Element Analysis

Figure 4

The relationship among the mini dental implant, equator attachment system, and the prepared model with RPD framework with acrylic base on edentulous areas: (a) the placement of mini dental implant at 16.5 mm distal to the distal surface of the last abutment tooth on both sides of edentulous ridges and (b) the silicon cap within the acrylic base attached on the RPD framework (i), the connection between the equator attachment and silicon cap within the acrylic base (ii), and the connection of the mini dental implant to the equator attachment system within acrylic base (iii).
