CONTOURING WAX PATTERNS FOR CROWNS Wax patterns for crowns can be contoured with specific shapes using the dental surveyor (Fig. Sprue, invest, cast, divest crown. Survival curves were calculated related to patient gender, prosthetic restoration (crown, FPD, RPD), abutment tooth location, and post properties (length, diameter, core material, cement). contours necessary for the RPD, a) current survey line, b) desired survey line, c) area of tooth to be reshaped to produce the desired survey line. Shirakura A, Lee H, Geminiani A, Ercoli C, Feng C. J Prosthet Dent. • If an abutment tooth requires a crown underneath an otherwise acceptable and serviceable RPD, the abutment surveyed crown will be fabricated to fit inside the clasp assembly of the existing RPD. Within the limitations outlined, this procedure allows the practitioner to use all-ceramic crowns in situations previously reserved for metal or metal-ceramic restorations. 3. Plummer, Metzler or Haeberle). Sometimes the supporting teeth require a full coverage restoration. Removable partial denture (RPD) abutment crowns are typically shaped to provide guide planes, rest seats, and retentive areas. 32. J Ir Dent Assoc.
