Drying and aging paint dispersions display a wealth of complex phenomena that make their study fascinating yet challenging. To meet the growing demand for sustainable, high-quality paints, it is essential to unravel the microscopic mechanisms underlying these phenomena. Visualising the governing dynamics is, however, intrinsically difficult because the dynamics are typically heterogeneous and s...
STUDY DESIGN An experimental pilot study using an acrylic interbody cage in a dog cervical spine fusion model. OBJECTIVE To compare bony fusion in autologous bone grafting with a novel acrylic cage in terms of preservation of disc height, biomechanical properties, and histologic characteristics. SUMMARY OF BACKGROUND DATA Degenerative diseases of cervical intervertebral discs are commonly t...
INTRODUCTION The aim of the study is to evaluate interfacial bond strength between silicone prosthetic elastomers and polymethylmethacrylate (PMMA). MATERIALS AND METHODS Silicone elastomers were attached to PMMA and a total 120 specimens were fabricated which were then subdivided into 12 sub-groups. Each sample was then subjected to laboratory test to determine the bond strength. The specime...
The purpose of this study is to compare the flexural strength values of four different methods for chair side direct transfer methods of implant housing. Materials and Methods: Sixty heat-cured polymethylmethacrylate denture blocks were prepared of size 11 (±0.5) x 8 (±0.5) x 38(±0.5) mm. At the centre a hole of 5mmx8mm dimension was made to secure the implant housing.The Implant Housings were ...
There is a great concern about the indoor microbial colonization especially in places that should have high standards of environmental hygiene. Besides, due it shortened useful life coating by discoloration and degradation. Currently this problem must be solved an innovative eco-friendly way. In sense, aim work was to develop green waterborne paint formulated with microcapsules containing essen...
Paints and coatings have been recognized as a useful type of forensic evidence for several decades. During this time the materials themselves, the analytical methods used to examine them, and the legal environment surrounding the use of scientific evidence in courts have all changed. This paper is not intended to provide a comprehensive bibliography on the topic, but rather to provide a concise...
A procedure was explained to fabricate a surgical stent to aid the placement of maxillofacial implants for prosthetic auricular rehabilitation. An impression of the defect was made, and a wax pattern of the missing ear completed and evaluated on the patient. The definitive wax prosthesis was processed in clear acrylic resin. Also an occlusal maxillary splint was fabricated and joined to the acr...
BACKGROUND Poor mechanical properties are among the main limitations of acrylic resins. Addition of titanium dioxide (TiO2) nanoparticles to acrylic resin has been shown to improve its mechanical properties with an adverse effect on its color. Thus, this study sought to assess the tensile and impact strength of a color modified heat cure acrylic resin reinforced with TiO2 nanoparticles. MATER...
Background and Purpose: In people wearing dentures, the growth of various Candida species under the prosthesis leads to the formation of biofilm, which can play the role of a reservoir for Candida and other kinds of microbes. Since nano-chitosan particles can cause lasting antimicrobial activity, a more recent approach that utilizes acrylic resins with nano-chitosan particles is proposed. Th...
A comparison of the impact strength between Acropars and Meliodent acrylic resins Dr. F. Golbidi* - Dr. A. Meghdadi** *-Assistant Professor of Prosthodontics Dept. – Faculty of Dentistry – Isfahan University of Medical Sciences. **-Dentist. Background and Aim: One of the mostly used materials in removable prostheses are acrylic resins with various physical and mechanical properties. The impact ...
