简要总结
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.
详细描述
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

入选标准
- •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.
排除标准
- •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.
