Overview

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.

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.

Intraoral scannerDEVICE

Use of an intraoral scanner to obtain digital impressions for the fabrication of intra-radicular attachments. Two different intraoral scanners will be used to capture digital data of the prepared tooth, and the resulting scans will be used to fabricate the attachments through a CAD/CAM workflow. The accuracy of the fit will be evaluated and compared with conventional impression techniques.

Inclusion Criteria: * 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. Exclusion Criteria: 1. Severely compromised remaining teeth with poor prognosis duetoextensive decay or severe periodontal disease. 2. Severe bone loss around abutment teeth. 3. Severe malocclusion making overdenture placement difficult. 4. Limited inter-arch space that cannot accommodate overdenturecomponents. 5. Poor oral hygiene increasing the risk of decay or periodontal issues. 6\. Patients medically unfit for any surgical procedure.

Outcomes

Primary Outcomes

Marginal and internal fit evaluated using software.

Time frame: Immediately after scanning

Secondary Outcomes

Time control, the time taken for each scanningor impression-taking process will be recorded in seconds using a stopwatch.

Time frame: During scanning
