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.
