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.
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.
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. 5. Poor oral hygiene increasing the risk of decay or periodontal issues.
