Digital approach to rehabilitating partially edentulous arch using advanced fabrication techniques for precision attachments in cast partial dentures: a case report

The integration of digital technologies in removable prosthodontics has significantly enhanced the precision, efficiency, and predictability of cast partial denture (CPD) fabrication. Conventional methods, often involving multiple manual steps, are prone to inaccuracies and technical errors that may compromise the prosthesis fit, patient comfort, and long-term clinical success. The advent of computer-aided design and computer-aided manufacturing (CAD/CAM), along with direct metal laser sintering (DMLS), has enabled the fabrication of high-precision frameworks and extracoronal precision attachments with improved biomechanical and esthetic outcomes. This case report presents the digital rehabilitation of a partially edentulous maxillary arch classified as Kennedy Class II Modification 2, utilizing a CAD/CAM-designed and DMLS-fabricated cast partial denture. The digital workflow encompassed intraoral scanning, virtual framework design, and additive manufacturing of the prosthesis with integrated precision attachments. Clinical outcomes demonstrated enhanced accuracy of fit, improved retention, and increased patient satisfaction, with a reduction in chairside adjustments. This report highlights the transformative impact of digital technologies on enhancing clinical standards and fostering personalized, patient-centered care in removable prosthodontics.
