A systematic review on volumetric analysis in orbital MRI.

Aim: Volumetric analysis of orbital soft tissues using magnetic resonance imaging (MRI) offers valuable diagnostic and pathophysiological insights into orbital inflammation, trauma, and tumors. However, the optimal MRI protocols and post-processing methods for specific conditions remain unclear.

Methods: A systematic search was performed in PubMed/MEDLINE, Web of Science, and Cochrane Library for all studies published before November 2024.

Intraoral scanning of the edentulous jaw without additional markers: An validation study on scanning precision and registration of an intraoral scan with a cone-beam computed tomography scan.

Purpose: A fully digital approach to oral prosthodontic rehabilitation requires the possibility of combining (i.e., registering) digital documentation from different sources.

Three-dimensional characterisation of the globe position in the orbit.

Purpose: Current methods to analyse the globe position, including Hertel exophthalmometry and computed tomography (CT), are limited to the axial plane and require the lateral orbital rim and cornea as landmarks. This pilot study aimed to design a method to measure the position of the globe in the axial, coronal and sagittal plane and independent from orbital bony and corneal references.

Methods: With the aid of three-dimensional CT reconstruction technology, we determined the globe position in the orbit based on the centre of the globe.

Validation of 3D documentation of palatal soft tissue shape, color, and irregularity with intraoral scanning.

Objectives: The purpose of this study was to assess the feasibility of 3D intraoral scanning for documentation of palatal soft tissue by evaluating the accuracy of shape, color, and curvature.

Materials And Methods: Intraoral scans of ten participants' upper dentition and palate were acquired with the TRIOS® 3D intraoral scanner by two observers. Conventional impressions were taken and digitized as a gold standard.
