Improvement of Acrylic Resins Structure in Removable Prosthesis Base Polymerization

Abstract

The materials used in additive techniques are initially in a plastic state so that they can be inserted into various cavities or easily molded after which they pass into a rigid phase. This process is performed by various methods, depending on the nature of the material. The study aims at analyzing the chemical and biological behavior of flexible acrylates compared to classical acrylates, whose structure was optimized through the introduction, at a structural level, of certain polymeric and antiseptic structures in view of obtaining a high degree of biocompatibility, the elements of variability consisting in the difference between the two polymerization regimes, the polymerization under pressure and the classical polymerization.The polymerization of acrylic resins by the technique of thermobaro-polymerization with injection compensation leads to the formation of materials with superior impact resistance. The pressure regime is very important, being a factor that influences the polymerization without being initiated. Breaking strength is an essential element in assessing the quality and duration of the prosthesis use.

Influence of Thermal Processing for 3D Printed Components

“…In medical field of wide use is the poly (lactic acid) (PLA), a thermoplastic polymer with characteristics similar to those of petroleum based ones [5], that can be used for various applications with the advantage that it is also biodegradable. Given the increasing concern on health and hygiene PLA has become a matrix for most antibacterial polymer composites [6][7][8][9][10][11][12][13][14][15][16][17][18].…”
