Abstract

The extent and direction of movement of removable partial dentures during function are influenced by the nature of supporting structures and the design of the prosthesis since forces are transmitted to abutment teeth by rest, guide planes, and direct retainers during functional movements. Because of the lack of tooth support distally, the denture base will have tissueward underfunction proportionate to the quality (displaceability) of the supporting soft tissue, the accuracy of the denture base, and the total occlusal load applied. The movement of the base under function determines the occlusal efficiency of the partial denture and the degree to which the abutment teeth are subjected to torque and tipping stresses.The purpose of this study is to know the functional load exerts with RPI and RPL direct retainer in bilateral distal extension. This study is a laboratory experiment employing samples of 5 frames using RPI and 5 frames using RPL direct retainer design. Testing was conducted by Vishay Teaching Polariscope type 080. The result was noted and analyzed statistically using ANOVA.The result of this study indicates that F calculation value for frame with RPI and RPL direct retainer design is 5,35 and 6,11 Mpa; F calculation for the occlusal load distribution on first premolar and edentulous area is 276,90 Mpa and 171,53 Mpa; F calculation for occlusal load distribution on first premolar and edentulous area employing RPI and RPL direct retainer design is 9,17 and 11,96 Mpa. This statistical calculation shows that there is a significant difference between RPI and RPL direct retainer design, the occlusal load concentrated at edentulous area either RPI or RPL direct retainer, and the occlusal load distribution between the first premolar and edentulous area are more uniform on RPI direct retainer design.

Abstract

Good quantity and quality of bones are keys to the success of prosthodontic treatment. The quantity of bones is showed by the height of mandibular residual ridge, whereas the quality of bones is indicated by the bone density.The aim of this study is to investigate the relationship between the age, the bone density, and the height of the mandibular residual ridge. The observation is carried out to six edentulous menopausal women. The height of mandibular residual ridge and the mandibular bone density are measured by using CBCT-3D (Cone Beam Computed Tomography-3 Dimension). Pearson analysis of bivariate correlation is used to determine the relation between variables. As a result, there is a strong correlation between the increased of the age and the decrease of mandibular bone density (r=-0.922 with α=0.009). The study also shows a significant correlation between the decrease of the height of mandibular residual ridge and the decrease of the mandibular bone density (r=0.815 with α=0.048) and between the decrease of the height of mandibular residual ridge and the increase of the age (r=-0.89 with α=0.017).To summarize, the decrease of the height of mandibular residual ridge in this study correlates with the decrease of the mandibular bone density and the age.
