2024年10月10日 · The RPI system, which includes an I-bar retentive element, mesial rest, and distal proximal plate, minimizes torqueing forces and directs occlusal loads parallel to the long axis of abutments, reducing lateral forces.

2020年4月29日 · Remember RPI system on free end saddles! Ensure you have a written description of your design, as drawings and pretty colours won't be enough. Here is a model design sheet for you to practice! Re-evaluate and confirm your surveying and denture design. Ensure the patient is happy with the design, including the material – In this case, Co-Cr.

2017年5月12日 · This document provides an overview of removable partial denture (RPD) design, with a focus on the RPI and RPA systems. It discusses the challenges of tooth-tissue supported prostheses and how RPD design can control damaging forces. The RPI system aims to minimize stress using components like I-bar retainers, mesial rests, and proximal plates.

2020年10月5日 · Direct retainer is a component of removal partial dentures (RPD), which is used to retain and prevent dislodgement, consisting of a clasp assembly or precision attachment. Depending on their placement inside (within) the abutment tooth or outside (surrounding) the abutment, direct retainers can be broadly classified as:

2019年9月27日 · Polyetheretherketone (PEEK) is a new material used for the frameworks of removable partial dentures (RPD). The questions whether the PEEK framework has similar stress distribution on...

2000年12月23日 · The RPI system is designed to allow vertical rotation of a distal extension saddle into the denture-bearing mucosa under occlusal loading without damaging the supporting structures of the...
