A comparison of profilometer and AutoCAD software techniques in evaluation of implant angulation in vitro

Purpose: The aim of this study was to compare 2 different methods of assessment of implants at different inclinations (90 degrees and 65 degrees)-with a profilometer and AutoCAD software. Materials and Methods: Impressions (n = 5) of a metal matrix containing 2 implants, 1 at 90 degrees to the surface and 1 at 65 degrees to the surface, were obtained with square impression copings joined together with dental floss splinting covered with autopolymerizing acrylic resin, an open custom tray, and vinyl polysiloxane impression material. Measurement of the angles (in degrees) of the implant analogs were assessed by the same blinded operator with a profilometer and through analysis of digitized images by AutoCAD software. For each implant analog, 3 readings were performed with each method. The results were subjected to a nonparametric Kruskal-Wallis test, with P <= .05 considered significant. Results: For implants perpendicular to the horizontal surface of the specimen (90 degrees), there were no significant differences between the mean measurements obtained with the profilometer (90.04 degrees) and AutoCAD (89.95 degrees; P=.9142). In the analyses of the angled implants at 65 degrees in relation to the horizontal surface of the specimen, significant differences were observed (P=.0472) between the mean readings with the profilometer (65.73 degrees) and AutoCAD (66.25 degrees). Conclusions: The degrees of accuracy of implant angulation recording vary among the techniques available and may vary depending on the angle of the implant. Further investigation is needed to determine the best test conditions and the best measuring technique for determination of the angle of the implant in vitro.

Utilização do AutoCAD 2004 para quantificação de pesquisas usando fotomicrografias eletrônicas

Objective: To determine if the AutoCAD 2004 program is available to be used in quantitative research on electron microscopy. Methods: A demonstrative of the AutoCAD2004 was done in an experimental model of diabetes induced in rats. The animals were divided by lot in control group animals (GC-10 animals) and diabetic group (GD - 10 animals), evaluated 1 month after the diabetes induction.The eyes were removed after sacrifice and prepared to electron microscopy. The retina was photographed and the AutoCAD2004 program was used to measure the basal membrane of retina vessels. The results were submitted to statistical analysis. Results:The AutoCAD2004 was effective to obtain quantitative measures from the basal membrane of retina vessels and there were no difference between the studied groups. Conclusion: The AutoCAD2004 was effective, safe and easy to apply to quantify biological parameters, which allowed suggest it to quantitative research.

Herramienta software para el aprendizaje de la generación de la cardiode en un entorno AutoCAD

This article presents a novel application which has been developed in Visual LISP for an AutoCAD environment, and which shows intuitively and quickly the generation of the Cardioid curve in five different ways (conchoid of a circumference, pedal curve of a circumference, inverse of a parabola, orthoptic curve of a circumference and epicycloid of a circumference). This cyclic curve has a large number of artistic and technical applications, among them the profile of some cams.

Innovative approaches to teaching engineering drawing at tertiary institutions

This paper arises from our concern for the level of teaching of engineering drawing at tertiary institutions in Australia. Little attention is paid to teaching hand drawing and tolerancing. Teaching of engineering drawing is usually limited to computer-aided design (CAD) using AutoCAD or one of the solid-modelling packages. As a result, many engineering graduates have diffi culties in understanding how views are produced in different projection angles, are unable to produce engineering drawings of professional quality, or read engineering drawings, and unable to select fits and limits or surface roughness. In the Faculty of Built Environment and Engineering at the Queensland University of Technology new approaches to teaching engineering drawing have been introduced. In this paper the results of these innovative approaches are examined through surveys and other research methods.

CADDS: an automated die design system for sheet-metal blanking

This article reports on the design and implementation of a Computer-Aided Die Design System (CADDS) for sheet-metal blanks. The system is designed by considering several factors, such as the complexity of blank geometry, reduction in scrap material, production requirements, availability of press equipment and standard parts, punch profile complexity, and tool elements manufacturing method. The interaction among these parameters and how they affect designers' decision patterns is described. The system is implemented by interfacing AutoCAD with the higher level languages FORTRAN 77 and AutoLISP. A database of standard die elements is created by parametric programming, which is an enhanced feature of AutoCAD. The greatest advantage achieved by the system is the rapid generation of the most efficient strip and die layouts, including information about the tool configuration.
