Telescope crown, konus (conus) crown, or insertion coping? Telescope crown, konus crown or conus crown, and insertion coping are all different names given to similar retention strategies for a removable prosthesis. They can be on dental implants or teeth. We can use these for dental partials with existing teeth or for a full arch prosthesis […]
Lost wax investment technique with teeth in a wax trial denture Advancements PMMA used since 1930’s polymethylmethacrylate Recent advancements is delivery of PMMA through injection molding In 2002 LC thermoplastic urethane-dimethacrylate resin Advantage of urethane-dimethacryalte No monomer No flasking and packing Short processing times Less than half volumetric shrinking compared to PMMA Will bond to […]
