The finite element method was used to calculate the stresses in a maxillary canine tooth produced during lateral and vertical condensation. Description of the biological domain to be analyzed, and conversion of the manual operations of the endodontist to realistic load representation are intricate problems which must be overcome before stresses are recovered and plotted. The stresses in dentin are in general of comparable magnitudes during lateral or vertical condensation, but these magnitudes generally remain much below those presented in a previous study. From these calculations it appears that root fractures reported by some investigators may be explained in terms of stress concentrations and local irregularities of the samples tested.

EFFECT OF GLASS IONOMER LINERS ON BONDING STRENGTH OF LAMINATE VENEERS KEDICI, PS; KALIPCILAR, B; BILIR, OG (Elsevier BV, 1992-07-01) This study compared shear bond strengths of porcelain laminate veneers, fabricated on refractory dies, which were lengthened incisally by 0.5 mm. Specimens were divided into four separate groups. In group A, the teeth were reduced 0.5 mm and the bonding was to enamel. The teeth of the remaining groups were reduced 1.0 mm and the bonding was to dentin. For two of the groups glass ionomer liners were applied before etching. Bonding to enamel was best, with cohesive fractures in porcelain. In the other groups,...
STRESSES INDUCED BY DIFFERENT LOADINGS AROUND WEAK ABUTMENTS AYDIN, AK; TEKKAYA, AE (Elsevier BV, 1992-12-01) Stresses and deflections of abutments induced by various loadings were analyzed with a two-dimensional finite element model. The biomechanic system consisted of the mandibular posterior three-unit fixed partial denture (FPD). Four different loading types were analyzed: (1) a distributed force of 600 N; (2) concentrated nonaxial and (3) axial 300 N forces at the marginal ridge of the molar; and (4) a concentrated vertical 300 N force at the center of the pontic. All computations were conducted for three diff...
A biomechanical comparison between original and used titanium miniplates Tuncer, N; Demiralp, AS; Guven, O; Keskin, A; Bor, S (Elsevier BV, 1996-02-01) Four dogs were chosen for this study, An experimental fracture was made in the mandibular symphysis region of each dog. Two miniplates and eight screws mere applied, and removed three and six months postoperatively.
Fatigue Resistance of 2 Different CAD/CAM Glass-Ceramic Materials Used for Single-Tooth Implant Crowns Cavusoglu, Yeliz; Sahin, Erdal; Gürbüz, Rıza; AKÇA, KIVANÇ (Ovid Technologies (Wolters Kluwer Health), 2011-10-01) Purpose: To evaluate the fatigue resistance of 2 different CAD/CAM in-office monoceramic materials with single-tooth implant-supported crowns in functional area.
A moment technique for adsorption rate on metal surfaces of supported catalysts CO adsorption on Pt-Al2O3 washcoated monolith Dogu, G; Ozkan, G; Doğu, Timur (2001-12-15) A moment technique was developed for the investigation of adsorption on metal surfaces of supported catalysts. The technique was applied to the evaluation of adsorption rate parameters of CO on a Pt-Al2O3 washcoated monolith. The adsorption rate constants evaluated in the temperature range 273-316 K showed significant decrease with an increase in surface coverage. Results of pulse response experiments corresponding to zero coverage gave the apparent activation energy for adsorption as 21 kJ/mol. This method...
