3D‐Printed Sinus Lift Training Models as an Educational Tool for Dental Students

Journal of Dental Education, EarlyView.
ABSTRACT Purpose/Objectives The aim of this study was to evaluate whether 3D‐printed models can be an inexpensive and suitable way to train dental students to perform a sinus lift. Methods The sinus lift model was created using CAD/CAM technology. Approximately one year prior to their final examination, thirty‐one dental students evaluated and tested ...

An Exploratory Comparative Analysis of Mixed Reality Simulation Versus 3D‐Printed Models for Undergraduate Training in Third Molar Removal

Journal of Dental Education, EarlyView.
ABSTRACT Purpose/Objectives To compare the effectiveness of MR simulation and 3D‐printed models in training undergraduate students in wisdom tooth removal, and to assess students’ perceptions of the MR simulator. Methods Students trained first on either the MR simulator or 3D‐printed plastic models and then repeated the training using the other method ...

Dosimetric Outcomes of Definitive Radiation Therapy to Anal Squamous Cell Carcinoma in a Single Institution Using Volumetric Modulated Arc Therapy Evaluated Against Australian and International Treatment Planning Guidelines

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated 43 clinically approved VMAT plans for anal squamous cell carcinoma (SCC) against RTOG, eviQ, ANROTAT and departmental planning guidelines to assess the achievability of current dose constraints. While most target coverage and median OAR dose objectives were within protocol, not all constraints were consistently met, supporting the ...

Comparison of Six‐ and Three‐Dimensional Error Corrections for the Planning Target Volume in Patients With Nasopharyngeal Cancer

Journal of Medical Radiation Sciences, EarlyView.
6D correction for CBCT achieves better dose coverage of target tumour volume than 3D correction in patients with nasopharyngeal carcinoma. 6D correction significantly improved the dose coverage of PTV‐low at 5 weeks after treatment as compared to 3D correction.

Intrafraction motion and impact of margin reduction for MR‐Linac online adaptive radiotherapy for pancreatic cancer treatments

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 17-24, March 2025.
This analysis included quantification of intrafraction motion in pancreas stereotactic ablative radiotherapy treated on the MR‐Linac, leading to the development of adjusted (PTV) margins. Intrafraction motion indicated an average target displacement of 1–3 mm, resulting in an adjusted PTV margin of 2 mm in the right–left and superior–inferior ...
