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.
