Abstract:
OBJECTIVETo establish the computer aided design (CAD) software platform of individualized abutment for the maxilla central incisor.
METHODSThree-dimentional data of the incisor was collected by scanning and geometric transformation. Data mainly included the occlusal part of the healing abutment, the location carinae of the bedpiece, the occlusal 1/3 part of the artificial gingiva's inner surface, and so on. The all-ceramic crown designed in advanced was "virtual cutback" to get the original data of the abutment's supragingival part. The abutment's in-gum part was designed to simulate the individual natural tooth root. The functions such as "data offset", "bi-rail sweep surface" and "loft surface" were used in the process of CAD.
RESULTSThe CAD route of the individualized all-ceramic abutment was set up. The functions and application methods were decided and the complete CAD process was realized.
CONCLUSIONSThe software platform was basically set up according to the requests of the dental clinic.
