Study Notes
- Prof. Kratochvil's design concepts in CAD/CAM RPDs will continue to be relevant.
- Conventional design principles apply to both lost/wax CAD/CAM RPDs and digital design principles.
- Digital workflow of framework fabrication includes obtaining impression, CAD designing, and exporting SLA file.
- Digital designing can be done using modeling CAD softwares like 3Shape Dental System and Exocad.
- Framework fabrication methods include milling (CNC), spark erosion, stereolithography (SLA), and selective laser melting (SLM).
- New materials in RPDs include thermoplastic resins (Tri-Mack Plastics Mfg. Corp) and high-performance polymers like PEEK, PAEK, and PEKK.
- Thermoplastic resins offer advantages such as better aesthetics, lighter weight, and excellent precision, but require more thicker clasps and may have challenges like color stability, difficult repair, and poor adherence.
- Implant-retained RPDs offer advantages like increased retention, stability, and improvement in patient satisfaction, but come with disadvantages like increased cost, surgical interventions, and complicated clinical and laboratory processes.
- Attachment options for implant-retained RPDs include healing caps, precision attachment (era/bar/locator), and abutments for a fixed prosthesis.
- Waves of innovation in RPD include evidence-based dentistry, implant-retained RPDs, and new materials.
