简要总结

This study aims to evaluate the marginal and internal fit of intra-radicular attachments fabricated by direct scanning using two different intraoral scanners compared to indirect scanning of conventional impressions.

详细描述

This study evaluates the marginal and internal fit of intra-radicular attachments fabricated using different techniques. It compares direct digital scanning with two intraoral scanners and indirect scanning using conventional impressions. The aim is to determine which method provides better adaptation and accuracy, and whether there are differences between the two scanners in achieving clinically acceptable fit.

入选标准

  • Endodontically treated teeth requiring intraradicular attachments.
  • Adequate oral hygiene.
  • Partially edentulous cases where compromised remaining teethcannot serve as abutments for traditional removable partial dentures (RPDs). -
  • Periodontally compromised teeth that can still be maintainedasoverdenture abutments with proper treatment.

排除标准

  • Severely compromised remaining teeth with poor prognosis duetoextensive decay or severe periodontal disease.
  • Severe bone loss around abutment teeth.
  • Severe malocclusion making overdenture placement difficult.
  • Limited inter-arch space that cannot accommodate overdenturecomponents.
  • Poor oral hygiene increasing the risk of decay or periodontal issues.
  • 6. Patients medically unfit for any surgical procedure.
