This study aims to evaluate the accuracy of intra-radicular attachments fabricated by direct scanning using three different scanners in vivo. The primary outcome will be the accuracy of the fabricated attachments, while secondary outcomes will includepatient-reported comfort during procedure of taking intraradicular attachment conventional impression and direct scanning.
The fabrication of intra-radicular attachments is a critical step in restoring endodontically treated teeth. The accuracy of these restorations directly impacts their clinical performance, including retention, marginal fit, and long-term success. With advancements in digital dentistry, intraoral scanners (IOS) have become increasingly popular for direct scanning of intra-radicular preparations. However, the accuracy of these scanners varies depending on their technology, software, and clinical conditions

Scanning of intra-radicular impression by desktop scanner
Direct scanning of the intra-radicular canal by Intraoral scanner A
Direct scanning of the intra-radicular canal by Intraoral scanner B

Accuracy
measure accuracy between the dimension of the prepared canal gained by intra-radicular impression and the dimension of the prepared canal directly by two different types of intraoral scanners
Time frame: Immediately after scanning.
Patient-reported comfort
Patient-reported comfort (assessed via a Likert scale questionnaire) Scaled from 0-100 The highest score means excellent The lowest score means unsatisfactory
Time frame: Immediately after impression taking and scanning.
