Purpose: The aim of the current study is to develop a novel method to investigate the accuracy of 3D scanners and digital articulation systems.
Materials And Methods: An upper and a lower poured stone model were created by taking impression of fully dentate male (fifty years old) participant. Titanium spheres were added to the models to allow for an easily recognisable geometric shape for measurement after scanning and digital articulation. Measurements were obtained using a Coordinate Measuring Machine to record volumetric error, articulation error and clinical effect error. Three scanners were compared, including the Imetric 3D iScan d104i, Shining 3D AutoScan-DS100 and 3Shape D800, as well as their respective digital articulation software packages. Stoneglass Industries PDC digital articulation system was also applied to the Imetric scans for comparison with the CMM measurements.
Results: All the scans displayed low volumetric error (p⟩0.05), indicating that the scanners themselves had a minor contribution to the articulation and clinical effect errors. The PDC digital articulation system was found to deliver the lowest average errors, with good repeatability of results.
Conclusion: The new measuring technique in the current study was able to assess the scanning and articulation accuracy of the four systems investigated. The PDC digital articulation system using Imetric scans was recommended as it displayed the lowest articulation error and clinical effect error with good repeatability. The low errors from the PDC system may have been due to its use of a 3D axis for alignment rather than the use of a best fit.

Case: A 30-year-old man presented with left proximal tibia fracture (open Grade 3A) and a transverse lateral malleolus fracture (Weber B) following direct impact injury. Computed tomography revealed a rare posteromedial tubercle fibula fracture at the posterior inferior tibiofibular ligament (PITFL) insertion, with syndesmosis disruption. Initial damage control included an external fixator.

The emerging phenomenon of digital exclusion raises an important issue that not everyone is equally engaged in and can benefit from the digital world. Older adults are particularly susceptible to digital exclusion, but a comprehensive conceptual treatment of digital exclusion in older adults is lacking in the psychology literature. In this article, we provide a taxonomy to advance the literature on digital exclusion in older adults, identifying key conceptual attributes of older adults' digital exclusion experiences by articulating both structural (i.

Background: Nowadays, computed tomography (CT) scanning is one of the most practical and precise diagnostic imaging methods that can be utilized to evaluate the head in birds.
Objectives: This study aimed to present the normal anatomical data of the head of the cockatiel (Nymphicus hollandicus) using the CT method. In this research, the features of this bird's head were investigated in terms of bones, joints, muscles, sinuses and other constituent tissues.

Objective: This study aimed to investigate the e!ect of arthroscopic Bankart repair (ABR) alone and ABR with an additional remplissage procedure on joint range of motion and functional results in patients with anterior shoulder instability.
Methods: This retrospective study included patients treated 1 year ago with either ABR alone or the ABR additional remplissage procedure. The Bankart lesion was determined by magnetic resonance imaging, and the amount of glenoid bone loss was determined by computed tomography.
