The aeronautical industry has begun to use advanced manufacturing and 3D printing for functional parts. The Product Design Laboratory (PDL) has studied the feasibility of manufacturing a part by Additive Manufacturing and has compared the geometric quality of the resulting part with those currently manufactured by plate assembly. Traditionally, we...

In dentistry, for different reasons, several processes necessary to respond to different patient needs must be performed outside the mouth. This forces to have an “extra ore” model of the patient’s masticatory apparatus. For this purpose, the best alternative today is the virtual articulator. For an effective use of the virtual articulator, it is n...

Statement of problem: Obtaining reliable digital scans of edentulous patients is challenging because of the absence of anatomic landmarks/geometric variations along the dental arch. Whether adding an auxiliary geometric device (AGD) will improve scanning is unclear. Purpose: The purpose of this in vitro study was to analyze the accuracy of compl...

The reuse of damaged stamps or forgingc dies is a key aspect of the forging process. Whenever a forging die must be repaired the damaged zones are filled with welding material to be later machined. In this process, some phases can be optimized as the amount of welding material and moreover the machining tool paths and parameters. With the introduct...

The virtual technique described in this article integrates reverse engineering and mandibular dynamics into dental computer-aided design and computer-aided manufacturing (CAD-CAM) systems. This technique aims to provide more objective information to the dental technician for the diagnosis, planning, and treatment phases. In order to carry out this...

Erratum to: Int J Interact Des Manuf DOI 10.1007/s12008-013-0203-2Unfortunately, the article title was published incorrectly in the original publication. The correct title should read as “Virtual production of dental prostheses using a dental virtual articulator”.

The clinical procedure described provides a quantifiable, repeatable, and reliable method of transferring the location of the maxillary dental arch from the patient directly to a virtual articulator (virtual facebow transfer) by means of reverse engineering devices to design a customized dental restoration. This procedure allows the dentist and the...

New methods of data acquisition such as 3D scanners have become increasingly necessary for the verification of the geometric dimensioning and tolerancing (GD&T) specifications in the manufacture of industrial parts. This paper proposes a method for the verification of a positional tolerance in two cylindrical features in an industrial part digitize...

Dental virtual articulators constitute a great improvement in the design of dental prostheses. The use of computer aided design (CAD) systems and Reverse engineering tools permits the introduction of kinematic analysis in virtual design processes. This paper presents a research project aiming at designing a dental virtual articulator in order to si...

This paper presents a research project aiming at designing a Virtual Articulator in order to simulate and analyze mandibular movements of the human jaw. Its main goal is to improve the design of dental prostheses, adding kinematic analysis to the design process. First, plaster models are scanned. Second, the type of articulator is selected. Third,...

This research project presents the construction of a Dental Virtual Articulator that permits the design of collision-free geometry on dental prostheses. Thanks to this articulator kinematic analysis can be taken into account in the design of dental prostheses. This is an improvement of the utmost importance in this field. Several steps have been fo...

This paper introduces a research project aiming at building a digital facebow with which maxillary casts (upper models or arcades) can be located on a virtual dental articulator. Its main goal is to improve the design process of dental prostheses by adding this virtual step to the already available methodology. The main practical implication of thi...

This article describes how life cycle assessments are performed in the ecodesign learning centre at the Faculty of Engineering in Bilbao (University of the Basque Country UPV-EHU) aiming at improving already existing products. In this case, the assessed product has been a series of switchgears for primary distribution manufactured by a company spec...

In current design and manufacturing processes, the verification of tolerances is mainly focused on dimensional tolerances. As a general rule, manufacturing instructions specify dimensional tolerances and surface qualities. However, geometric tolerances are hardly ever specified, and this often leads to a lack of adequacy of the design. A better ade...

This article describes a digital technique to transfer the location of digitized casts obtained directly from the patient to a virtual articulator (digital/virtual facebow transfer). The primary advantage of this technique is that it allows the dentist and the dental laboratory technician to work in a fully digital environment without having to mou...

The implementation of computer-aided design/computer-aided manufacturing (CAD/CAM) systems with virtual articulators, which take into account the kinematics, constitutes a breakthrough in the construction of customised dental prostheses. This paper presents a multidisciplinary protocol involving CAM techniques to produce dental prostheses. This pro...

When designing a custom-made dental restoration, using a digital workflow represents an important advance over mechanical tools such as facebows or mechanical articulators. When using virtual scanning procedures, there is a direct transfer from the patient to the articulator. This paper presents a novel methodology to design custom-made restoration...

: In recent years, the development of medical science has been marked by an increasingly interdisciplinary, which could be attributed to various engineering applications. The rapid development of computer-aided technologies, which completely transformed the production engineering, has also left an indelible mark in dentistry. Especially in the area...

The main practical implications of...

Purpose: This paper describes the first step of a project that aims to improve the design and placement of dental prostheses through an in-depth analysis of jaw movement. This analysis requires prior obtaining quality digital models of all elements involved in the movement. The paper describes the process to obtain the digital models through Revers...

This paper describes the process to obtain a high quality digital model of a human skull, by reverse engineering techniques. This development was made in the Product Design Laboratory (PDL), in the Faculty of Engineering of Bilbao (The University of the Basque Country). The digitalization of the skull is the first stage of a project that PDL is dev...
