Resistência à tração de coroas de NiCr cimentadas sobre munhões de liga de titânio, com 4 diferentes tipos de cimentos

In this work of tensile strength was evaluated the efficacy of 4 cements (S. S. White zinc phoshate, Ketac Cem Easymix glass ionomer, RelyX Luting 2 composite resin/glass ionomer and Panavia 21 TC special acrylic resin) used to fix NiCr crowns to usinated titanium alloy abutments. Were used 40 abutments distributed in groups of 10 elements, to each material. The mechanical essays were developed at a MTS 810 universal machine, adjusted to a 0.5 mm/m velocity. The ANOVA applied to data pointed out the existence of significant differences between groups; the subsequent Tukey´s test (p<0.05) also detected significant differences, except at comparisons of phosphate versus RelyX and phosphate versus Ketac Cem. The better performance was presented by Panavia 21 (1,127.996 N); RelyX (478.197 N) showed itself similar only to phosphate (430.662 N), wich had a performance similar to that of Ketac Cem (227.705 N).

Proposta de melhoria do layout de um armazém de vidros automotivos

This work was based on a case study of improvement of the warehouse layout of a multinational automotive glass sector, located in the State of Sao Paulo. The aim was to propose a layout template to be more effective and besides optimizing production would also promote an increase in warehouse packaging capacity for metal containers containing glasses, thus reducing operating costs. To achieve the desired purpose, it was developed two layout proposals and to this end inventory management tools have been used, such as ABC curve and the Spaghetti Diagram, and other concepts of Packaging Engineering and Logistics. By the end of this work, it was obtained as a result, a project in which it was possible to rearrange the packages according the demand, and the developed changes became the most efficient layout both in storage capacity as well as in the internal drive

Limitations of enamel microabrasion technique applied in a pediatric patient: case report

Enamel microabrasion is a non-invasive method that removes intrinsic and superficial defects from teeth aimed to improve dental esthetic with minimal loss of dental tissue. This case presentation describes the attempt for teeth color correction utilizing that conservative technique in a young girl whose upper central incisor presented an opaque white stain. Scanning electron microscopy (SEM) was conducted in order to illustrate the glasslike luster and a smooth texture of microabraded enamel surface. The correct diagnosis of defect is a difficult task, when consider this conservative approach.

Effect of ultrasonic ecxitation on the ultimate tensili strength of glass ionomer cements after different water storage times

The application of ultrasound waves with a conventional dental ultrasonic scaler on glass ionomer cements surface accelerated initial setting reaction and improved the mechanical properties. Objective: This study evaluated the ultimate tensile strength of glass ionomer cements after ultrasonic excitation and different water storage times. Material and method: Twelve specimens of each material (Fuji IX GP, Ketac Molar Easymix and Vitremer) were prepared, and six of each received a 30-second ultrasound application during initial setting of the cements. After storage of the 24 hours or 30 days, the specimens were sectioned into stick to microtensile testing and the mean ultimate tensile strength values were submitted to Welch’s ANOVA and Tamhane’s test. Result: The results showed that the Vitremer presented the highest mean tensile strength. The chemically set Fuji IX GP presented significantly higher mean tensile strength after 30 days than after 24 hours of storage (p < 0.05). At 24 hours, the ultrasonically set Fuji IX GP presented significantly higher mean tensile strength than their counterparts set under standard conditions (p < 0.05). Conclusion: Treatment with ultrasound increased the tensile strength of Fuji IX GP in the early period of maturation.

Protese total fixa em função imediata confeccionada em resina composta indireta

Immediate functioning of osseointegrated implants has been widely employed in edentulous patients due to its safety and high predictability. However, viability and success of immediate-loaded implants is defined by factors such as number of implants, distribution and splinting, as well as reduction of oblique loads and excessive occlusal contacts. The indirect composite resin-modified glass enable building of a highly aesthetic prosthesis, combining satisfactory resistance and better force dissipation on occlusal loading. This article describes a resin composite, mandibular fixed prosthesis on osseointegrated implants in immediate function.
