TL;DR
Cavity depth and tooth structure thickness significantly influenced the accuracy of intraoral scanners in endocrown restorations and significantly influenced the accuracy of intraoral scanners in endocrown restorations.
OBJECTIVE To evaluate the effects of pulp chamber depth, tooth type, and intraoral scanner (IOS) on the accuracy of endocrown digital impressions. MATERIALS AND METHODS Standardized endocrown preparations with 2 and 5 mm pulp chamber depths were performed on molar and premolar typodonts. Digital impressions were obta...
Evaluating how different ISB designs affect the trueness and precision of digital impressions in a completely edentulous maxillary arch with multiple implants found significant differences were found among ISBs in both trueness and precision.
OBJECTIVE The accuracy of intraoral scanners is commonly described by trueness and precision; however, the extent to which single-tooth crown preparation geometry influences these outcomes across different scanner systems remains unclear. This in vitro study aimed to evaluate trueness and to descriptively assess precis...
Both Medit i900 and Dexis IS 3800W provided clinically acceptable accuracy for Kennedy Class I mandibular arches, and accuracy was influenced by scanner type, tip size, and scanned area.
Scanner accuracy varied significantly, with Primescan and Trios 4 demonstrating superior trueness and precision and iTero and Medit showed reduced accuracy, particularly in angular measurements.
