Digital impressions in prosthodontics are emerging as an alternative to traditional elastomeric impressions. Various digital impression systems like CEREC, E4D, iTero, and Lava COS use intraoral scanners with blue or red lasers to optically capture 3D images of the teeth and produce digital models. This eliminates the need for physical impressions and allows for viewing of the occlusion digitally. The digital files can be used to directly mill restorations chairside or be sent to a lab for fabrication. Benefits include accuracy, reduced errors and cross-contamination control compared to conventional impressions. However, the equipment has high costs and requires trained personnel. Overall, digital impressions are expected to become more common
The document describes the Digital Denture process which allows for both digital and conventional steps in denture fabrication. Key steps include taking an initial impression and bite registration, scanning these to create virtual models, designing the dentures digitally including defining the occlusal plane and esthetic lines, and milling customized trays and a positioning jig. The denture teeth are then bonded to the milled denture base using the positioning jig before final milling and polishing.

Indirect Digital Workflow for Virtual Cross-Mounting of Fixed Implant-Support...PapaDoc3
This document describes an indirect digital workflow for virtually cross-mounting fixed implant-supported prostheses to create a 3D virtual patient. Scans of the patient's face, interim prostheses, and CBCT images were used to digitally transfer the maxilla's position to a virtual articulator. This allows mounting casts accurately in the patient's centric relation without physical articulators or mounting plates. The technique aims to reproduce the maxillomandibular relationship independently of occlusal contacts for repeatable registration. It provides advantages like improved treatment planning and reduced chairside time compared to conventional methods.
This document summarizes a seminar presentation on using CAD/CAE software in bio-medical applications. CAD/CAE techniques are commonly used for engineering purposes like design and analysis, but can also support medical fields through applications in dentistry, prosthetics, bio-mechanical studies, and archaeology.

CAKE: Sharing Slices of Confidential Data on BlockchainClaudio Di Ciccio
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

This article describes a technique to make an implant-retained maxillofacial prosthesis using CAD/CAM technology
and a rapid prototyping machine. The primary advantage of this technique is virtual 3-dimensional integration of the
defective surface with the mirrored and digitalized normal ear. Making an impression of the defective side is not neces-
sary, because only the position of the implants must be recorded to develop the bar for the retention of the prosthesis.
This procedure allows positioning of the ear straight onto the computer screen, eliminating the diagnostic waxing,
