QDT 2004 uccessful osseointegration and function have traditionally been the main goals of implant therapy. However, successful osseointegration does not automatically lead to an optimal esthetic result, and inadequate treatment planning may severely compromise the esthetic result regardless of biologic and functional integration. Exact replication of the natural dentition, maintenance of a har...

The replacement of a single missing anterior tooth with an implant-supported crown is a demanding therapy. This report describes a treatment in which an anterior maxillary implant was immediately restored with a provisional restoration. During the provisional phase, an optimal emergence profile was created by adjusting the provisional restoration. An impression was made with an individually fab...

Management, be it multi-access, resource, mobility or network management, is a key aspect in the design, deployment and operation of current and future networks. The challenges that mobile network management faces today are increasingly associated with the multiplicity of operating environments. For instance, heterogeneous resource sharing, dealing with a larger variety of user profiles, and op...

Extending the Unified Modelling Language (UML) version 2.0 with a profile and stereotypes that allow the modelling of an approval system with multiple levels, each with inherently dualistic complementarity, allows the high-fidelity characterization of the stacked levels of a real world approval hierarchy. The objective was to extend UML to model the complex, emergent and multi-level decision ma...

With the emergence of the first 3G mobile technologies in everyday life, mobile phones and PDAs are able to function as more than just simple means of communication. Research on these devices, in combination with 3G networks includes the development and use of a context aware personal assistant to support users. The Youngster project was one of the pioneers, which sought solutions for a more ef...

One of the new challenges of learning in a partly-networked world is to open the field of mobility for e-learning applications. Currently, a large majority of applications are developed for ``PC-like'' computers connected to the Internet with high bandwidth, interacting with the user through mouse and screen. But with the emergence of wireless connectivity and small devices one can think to oth...

This review article discusses the current role of ultrasound in interventional spine practice as both a diagnostic tool and as a modality for image guidance with procedures. Epidemiology of spine pain, the emergence of ultrasound, advantages and disadvantages of ultrasound in comparison to other image modalities are discussed. Recent selected published articles pertaining to the role of ultraso...
