This study was conducted to observe the changes in impact resistance of a denture base resin reinforced with five types of fiber. E-glass, polyester, rayon, nylon 6, and nylon 6/6 fibers were cut into 2, 4, and 6 mm lengths and added into the resin at a concentration of 3% by weight. Five test specimens for each formulation, as well as control specimens without fiber, were prepared using a mold including a V-shaped notch with 55 x 10 x 10 mm dimensions. Impact tests were carried out using a Charpy-type tester. Additionally, surfaces of the impact sections were observed under a scanning electron microscope (SEM). Results indicated that impact energy tended to increase with fiber length, and that the highest value was recorded for rayon fiber-reinforced specimens of 6 mm length. E-glass fiber reinforcement produced relatively stable, high values for each length, whereby good interfacial strength between polymer matrix and glass fibers was confirmed by SEM analysis.

In vitro Comparison of Autoclave Polymerization on the Transverse Strength of Denture Base Resins Durkan, Rukiye; ÖZEL, MEHMET BİROL; Bagis, Bora; Usanmaz, Ali (Japanese Society for Dental Materials and Devices, 2008-07-01) The aim of this study was to determine the effect of autoclave polymerization on the transverse strength of denture base polymers. To this end, 30 rectangular test specimens were fabricated of two heat-polymerized denture base polymers. The test groups were: (I) control. i.e.. conventional water bath to polymerize result by heat at 100 degrees C for 30 minutes; (II) autoclave polymerization at 60 degrees C for 30 minutes followed by 130 degrees C for 10 minutes; and (III) autoclave polymerization at 60 degr...
The effect of acquired salivary pellicle on the surface free energy and wettability of different denture base materials Sipahi, C; Anil, N; Bayramlı, Erdal (Elsevier BV, 2001-03-01) Objective: The objective of the present study was to evaluate the effect of salivary coating on the wettability and surface free energy of different denture base materials.
THE EFFECT OF HEAT-TREATMENT ON THE PROPERTIES OF PEEK AND APC2 FOLKES, MJ; KALAY, G (Elsevier BV, 1993-01-01) The effects of various thermal treatments on the properties of both PEEK and APC2 have been systematically studied. X-ray diffraction data, together with dynamic mechanical measurements, indicate that the T(g) values for both materials are considerably higher than those generally reported. Also, the tan delta values for quenched APC2 specimens are considerably higher than for slowly cooled materials. Microstructural observations show that this is likely to be due to poor fibre/matrix adhesion, in the case o...
The biomechanical relationship between incisor and condylar guidances in deep bite and normal cases Darendeliler, N; Dincer, M; Soylu, Reşit (Wiley, 2004-05-01) The purpose of this study was to investigate the biomechanical relationship between the condylar and anterior guidances in deep bite malocclusion and control groups. The subjects consisted of 18 deep bite patients and 14 normal occlusions. A four-bar mechanism was described on the lateral cephalogram films and a computer program, for which the lengths of the links measured on the films were the inputs, was developed. The computer program was used to calculate the angles of rotation of the mandible and the c...
ANALYSIS OF STRESS-DISTRIBUTION IN A VERTICALLY CONDENSED MAXILLARY CENTRAL INCISOR ROOT-CANAL YAMAN, SD; ALACAM, T; Yaman, Yavuz (Elsevier BV, 1995-06-01) In this study, the stress distribution in a maxillary central incisor subjected to an endodontic treatment was determined by using a three-dimensional finite-element method, The tooth had a variable root canal cross-sectional area, and the canal was assumed to be filled with vertical condensation. The Clinical practice was simulated by considering the obturation in successive stages, The main aim of the study was to investigate the possibility of fracture due to the obturation process, It was found that, wi...
