AI Article Synopsis
- - This study addresses the challenges in implant dentistry regarding accurate digital data positioning for patients with missing teeth, emphasizing the need for effective fiducial markers (reference points).
- - The researchers tested 15 different dental materials as fiducial markers to see which produced the least amount of radiographic artifacts on cone beam computed tomography (CBCT) scans, using 3D modeling software for analysis.
- - Findings revealed that flowable composite resin generated the least artifacts compared to other materials, suggesting it is a better choice for fiducial markers in CBCT imaging to enhance accuracy in dental implant procedures.
Article Abstract
Abstract Background/purpose: Computer aided implant surgery has been widely adopted in modern implant dentistry. However, absence of reliable anatomic landmarks for superimposing digital data sets for patients with terminal dentition or complete edentulism remained challenging. Utilization of additional fiducial markers intraorally as the reference points for the improvement of accuracy became crucial in implant digital workflow. Nevertheless, the choice of the material for fiducial markers should present the least radiographic artifacts under cone beam computed tomography (CBCT) for better accuracy. The aim of this in vitro study was to investigate the volume of radiographic artifacts generated through different materials under the image of CBCT.
Materials And Methods: Fifteen dental materials were selected and configured into cubic shape. All the materials were scanned initially with the laboratory scanner as the control groups. The samples were scanned by CBCT machine as test groups and the volume of artifact generated under CBCT images were compared and analyzed using 3D modeling software.
Results: Eleven out of fifteen materials could be recognized under CBCT images. Volumetric analysis reported that statistically significant differences among the materials could be noted, and the flowable composite resin presented the least volumetric difference. Lithium disilicate glass-ceramic, flowable composite resin, and gutta-percha presented the least deformation and maintained their cubic shapes.
Conclusion: The results of the present study may imply that flowable composite resin compared to all ceramic materials, amalgam and gutta-percha may be a preferable choice when utilized as fiducial markers under CBCT images.

Background And Purpose: The aim was to estimate the cost of the external beam radiotherapy (EBRT) in public health care centers in Catalonia (Spain), according to the ESTRO-HERO costing model for 2018.
Materials And Methods: Personnel, equipment, and activity data from 2018 from the 11 RT centers were used, incorporating European mean values adapted to the Catalan context. Secondly, EBRT costs were estimated, incorporating 2023 fractionation technique and scheme usage percentages.

Advancements in cryo-EM have stimulated a revolution in structural biology. Yet, for membrane proteins near the cryo-EM size threshold of approximately 40 kDa, including transporters and G-protein coupled receptors, the absence of distinguishable structural features makes image alignment and structure determination a significant challenge. Furthermore, resolving more than one protein conformation within a sample, a major advantage of cryo-EM, represents an even greater degree of difficulty.

Purpose/objective: MR-only radiotherapy planning exploits the benefits of MRI soft-tissue delineation, whilst negating the registration inaccuracies caused by MRI CT fusion. Fiducial markers have conventionally been used in prostate radiotherapy to reduce on-treatment image matching variability. However, this is an invasive procedure for the patient, and presents technical difficulties in an MR-only pathway as fiducial markers are difficult to visualise on MRI.

Cryo-electron tomography is an imaging technique that allows the study of the three-dimensional structure of a wide range of biological samples, from entire cellular environments to purified specimens. This technique collects a series of images from different views of the specimen by tilting the sample stage in the microscope. Subsequently, this information is combined into a three-dimensional reconstruction.

Background: Posture of the upper neck is considered by some to contribute to neck pain and headache. Infrared reflectors and cameras permit non-invasive three-dimensional (3D) evaluation of head and neck range of motion but have not been used to examine the relative pose (position and orientation) of the head, upper and lower neck.
Research Question: Can the relative 3D pose of the head, upper and lower neck regions of adult humans be non-invasively measured and perturbated while recording the characteristics of neck or head pain?
Methods: An optical motion capture system was used in a repeat measure descriptive analysis study.
