Clinical Significance of Internal Friction Connection and Micro-Threads in Implant-Supported Prostheses: A Literature Review

Received: 13 August 2020;  Published: 17 December 2020;  doi: 10.21926/rpm.2004024

Abstract

A connection structure using both a screw and friction is advantageous to secure an abutment to an implant. Understanding the biomechanics of the implant-abutment connection is necessary for the long-term clinical survival of a dental implant with decreased complications. The internal conical friction connection structure and micro-threads have shown favorable biological hard tissue response with exceptional structural features. The internal conical connection structure maintains the [...]

The Effect of Curing Temperature on the Morphology and Electro-Optical Properties of a Flexible UV-Cured Polymer Dispersed Liquid Crystal (PDLC)

Received: 11 October 2020;  Published: 08 December 2020;  doi: 10.21926/rpm.2004023

Abstract

In this work, the experimental data on flexible PDLC films at the industrial scale and the effect of cure temperature (Tc) on the morphology and electro-optical properties of a UV-cured PDLC system via polymer-induced phase separation (PIPS) method were studied. Under constant UV radiation intebsity and thickness, the morphological parameters such as dimension, number density, and volume fraction of the phase-separated liquid crystal droplets as well as the optical transmissions and switching vo [...]

Mechanical and Rheological Properties of 3D Printable Cement Composites

Received: 29 July 2020;  Published: 23 October 2020;  doi: 10.21926/rpm.2004022

Abstract

Additive manufacturing is a recent revolution in the construction field since cementitious materials became printable. This extrusion technique has enabled the construction of very complex geometry with a reduction in costs, time and labour interventions. This study aims to evaluate the possibility of reinforcing 3D printable cementitious composites with the use of nano and micro materials, particularly nano silica, micro silica and microfibrillated cellulose (MFC) which are known for their abil [...]
