Aim:

To analyze the fracture resistance of three post systems and their mechanism of failure.

Materials and Procedures:

Forty-five newly excised human mandibular single-rooted pre-molar, for periodontal or orthodontic reasons, were used. The teeth were separated into three groups (n = 15) based on the post system utilized. Group A had teeth restored with custom cast post; Group B had prefabricated glass fiber posts (Angelus post); and Group C with edelweiss composite post (Edelweiss Post).

Results:

The custom cast posts provided the highest fracture resistance but exhibited more unfavorable fractures. The edelweiss posts exhibited the least fracture resistance.

Conclusion:

Further investigations should be targeted at elucidating the force dynamics of this newer post system.
