Objectives. Polyamide-12 (PA) is a flexible material suited for denture bases and clasping. This study investigated its potential aging effects with a focus on surface roughness, color stability, and elasticity. Methods. PA specimens (Valplast) of 40 × 10 × 2mm and equally measuring PMMA specimens (Palapress) as control were fabricated. Color changes after storage in air, water, coffee, and red wine (n = 10) were measured using the CIE L*a*b color specification. Elasticity after thermocycling (1000, 3000, and 7000 cycles, n = 15) was measured by three-point bending testing. Mean surface roughn

Among them, flexural fatigue and impact are the most common failure mechanisms of an acrylic denture base. It has been shown that there is a correlation between the static strength and fatigue life of composite resins. Therefore, the transverse strength of the denture base materials can be an important indicator of their service life. In order to improve the fracture resistance of PMMA, extensive studies have

碩士<br>國立臺灣科技大學<br>化學工程系<br>100<br>The common problems encountered for dentures include: (i) the loss of adhesion between soft linings and denture base, and (ii) the growth of microorganism and formation of biofilm on the denture which usually resulted in bad smelling and hygiene concerns. This study aims to incorporate antifouling molecules onto the denture base materials and to evaluate the variation of the adhesion between soft linings (Molloplast B) and denture bases (Luctione 199). Two chemical grafting methods were proposed in this study to incorporate mPEG (poly(ethylene glycol) methyl e

Submitted in fulfillment of the requirements for the award of the degree of Master of Health Sciences: Dental Technology, Durban University of Technology, Durban, South Africa, 2017.<br>The poor mechanical properties of denture base acrylic resins can cause dentures to fracture either through impact or stress fatigue. Various metal reinforcing materials such as powders, nets, plates and wires together with synthetic fibres are therefore used to improve the strength properties of denture base acrylic resins. Despite their benefits, they are difficult to apply during fabrication, are costly, non

Johannesburg, 2013<br>Background: The majority of edentulous patients are unable to afford anything other than mucosa-borne complete dentures, but the conventional methods of complete denture fabrication can be lengthy and expensive. Simplified techniques have been proposed to reduce the number of clinical visits as well as the laboratory time

In this study, Luciton 199 ( Dentsply, USA ) was used as the denture base substrate with diff-erent repair-joint designs (butt, round, and 45 degree bevel ). Specimens of denture base acrylic resins were repaired with autopolymerized ( Repair Materi-al, Dentsply USA ) and visible light-cured ( Triad, Dentsply, USA ) repair ma

This research selected two kinds of hot spring water to be the models, which are the green sulfonic springs and white sulfonic springs. The purpose of the research is to improve the health and quality of life of human beings through the diversified use of hot springs resources. The first experiment is start from by making the

Statement of the Problem: Despite its popularity as a denture-base material, poly-methyl methacrylate exhibits inherently low resistance to impact and fatigue failure. This is reflected in the analyses of the prevalence of denture fracture which suggests that prosthesis failure remains an unsolved problem. Consequently, various approaches to improve the physical and mechanical properties of denture-base polymers have been proposed. These include incorporation of solid metal forms and various types of fibers to provide reinforcement to fracture prone areas. In recent years there has been consid

Submitted in fulfillment of the Degree of Master in Technology: Dental Technology in the Department of Dental Services Faculty of Health Sciences, Durban University of Technology, 2008.<br>Globally in the field of Dental Technology, polymethyl methacrylate (PMMA) resin continues to be the popular material for the fabrication of denture bases in removable prosthodontics. However, the mechanical strength of the denture base is a concern due to fractures occurring intra-orally or when accidentally dropped. The objective of this in vitro investigation was therefore to evaluate and compar
