[Three dimensional finite element stress analysis in the vertical fractured first premolar after bonding and replantation].

Abstract

PURPOSE:

To evaluate the change of stress distribution after bonding and replantation of vertical fractured first maxillary premolar.

METHODS:

The stress distribution in two types of loading and different treatments on the vertical fractured first maxillary premolar were analyzed by three dimensional finite element. The gap was respectively filled with Clearfil SE Bond and Super Bond C & B; and vertical and lateral stress force was calculated.

RESULTS:

The result of the FEM study of adhesive fracture tooth indicated that the stress distribution was similar to the normal tooth, Clearfil SE Bond was better than Super Bond C & B.

CONCLUSION:

The treatment of bonding and replantation for vertical fractured tooth is effective.
