Abstract

BACKGROUND:

Molars are the main functional teeth, and molar repairing is able to improve the biological function of molars and has the sturdy histological effect.

OBJECTIVE:

To evaluate the application effect of different post-core materials in molar repairing.

METHODS:

The patients received molar repairing with amalgam post-core, cast post-core and fiber post-core were followed-up to observe the incidence of prosthesis loosening, fracture, loss, periodontitis and gingivitis. The combination between post-core crown prosthesis and dental body, broken root canal and the resorption of alveolar bone of root tip and root body were tested with X-ray film. The biocompatibility of different post-core materials used for molar repairing was evaluated and compared.

RESULTS AND CONCLUSION:

The amalgam post-core, cast post-core and fiber post-core have good effects for the repair of molars. But compared with cast post-core, the amalgam post-core and fiber post-core have better biocompatibility, lower incidence of prosthesis loosening, fracture, loss, periodontitis and gingivitis, and have better histological effect, considered as the best post-core materials for molar repairing.
