Official title
Effect of Scanning Technology on the Accuracy of Digitally Customized Intraradicular Attachments: A Cross Overstudy
Overview
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.
Detailed description
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
Interventions
- Device 3 shape desktop scanner
Scanning of intra-radicular impression by desktop scanner - Device SHINING 3D intraoral scanner
Direct scanning of the intra-radicular canal by Intraoral scanner A - Device Planmeca Emerald S intraoral scanner
Direct scanning of the intra-radicular canal by Intraoral scanner B
Primary outcome measures
- Accuracy [Time frame: Immediately after scanning.]
Secondary outcome measures (1)
- Patient-reported comfort [Time frame: Immediately after impression taking and scanning.]
Eligibility criteria
Inclusion criteria
- Patients aged 18-65 years.
- Endodontically treated teeth requiring intra-radicular attachments.
- Adequate oral hygiene .
- Periodontally Compromised Teeth: When some teeth have reduced bone support but can still be maintained as overdenture abutments with proper treatment.
Exclusion criteria
- Severely Compromised Remaining Teeth: If the remaining teeth have poor prognosis due to extensive decay or severe periodontal disease.
- Severe Bone Loss Around Abutment Teeth: If the remaining teeth do not provide adequate support, they may fail early, leading to additional complications.
- Severe Malocclusion: Where occlusal discrepancies make overdenture placement difficult.
- Limited inter-arch Space: cann't accommodate the overdenture components. 5 . Poor Oral Hygiene: increase the risk of decay or periodontal issues in retained abutments.
