Abstract

OBJECTIVE:

To establish the computer aided design (CAD) software platform of individualized abutment for the maxilla central incisor.

METHODS:

Three-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.

RESULTS:

The 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.

CONCLUSIONS:

The software platform was basically set up according to the requests of the dental clinic.
