Comparison of conventional and digital impression approaches for edentulous maxilla: clinical study

Sinem Kahya Karaca & Kıvanc Akca. BMC Oral Health volume. 2024

The expectations for the clinical and laboratory phases of tissue-supported complete dentures (TSCDs) are changing. Currently, there is a trend towards fast, comfortable, reliable, and low-cost methods.

In TSCD impressions, simplified impression and digital impression methods involving the use of an intraoral scanner (IOS) are becoming preferable. Given this situation, this study aims to compare different conventional and digital impression methods used in TSCDs.

Three-dimensional differences between intraoral scans and conventional impressions of edentulous jaws: A clinical study

Lo Russo et al. J Prosthet Dent 2019

"Intraoral scans of edentulous jaws are feasible, and their accuracy is not significantly different from that of conventional impressions, either clinically or statistically."

Trueness and precision of intraoral scanners in the maxillary dental arch: an in vivo analysis

Winkler et al. Sci Rep. 2020

"The overall difference of the median precision measurements between the two scanners was approximately 10 μm (0.0098 mm). However, the lowest precision was detected for TRIOS 3 scans of a specific patient."

Automated Caries Detection using a 3D Intraoral Scanner. An in Vivo Validation Study

Michou et al. 2021 Scientific Reports

The use of 3D intraoral scanners (IOS) and software that can support automated detection and objective monitoring of oral diseases such as caries, tooth wear or periodontal diseases is increasingly receiving attention from researchers and industry. This study clinically validates an automated caries scoring system for occlusal caries detection and classification, previously developed for an IOS system featuring fluorescence (TRIOS 4, 3Shape TRIOS A/S, Denmark).
