Comparative in vitro study of the accuracy of impression techniques for dental implants: Direct technique with an elastomeric impression material versus intraoral scanner

Medicina Oral Patología Oral y Cirugia Bucal, 2018
The aim of this study was to compare a conventional technique (elastomeric impression material - EIM) and a digital technique (scanner digital model - SDM) on a six-analog master model (MM) to determine which was the most exact.Twenty impressions were taken of a master model (EIM) and twenty scanned impressions (SDM) (True Definition).

Pre-Training with Diffusion models for Dental Radiography segmentation [PDF]

arXiv, 2023
Medical radiography segmentation, and specifically dental radiography, is highly limited by the cost of labeling which requires specific expertise and labor-intensive annotations. In this work, we propose a straightforward pre-training method for semantic segmentation leveraging Denoising Diffusion Probabilistic Models (DDPM), which have shown ...

Prepolarized MRI of Hard Tissues and Solid-State Matter [PDF]

, 2021
Prepolarized Magnetic Resonance Imaging (PMRI) is a long-established technique conceived to counteract the loss in signal-to-noise ratio (SNR) inherent to low-field MRI systems. When it comes to hard biological tissues and solid-state matter, PMRI is severely restricted by their ultra-short characteristic relaxation times.
