The Finite Element Analysis has been used for stress analysis of prosthesis,
orthodontic or orthopedic appliances and filling materials.
The primary purpose of the present studying was to evaluate the effectiveness of
needle post in promoting the retention and integrity of composite crown restored on the
pulpotomized primary central incisor.
Three finite element models-natural tooth (Sample I), composite crown with (Sample
¥±) and without (Sample ¥²) needle post-were constructed and the stress distribution
within each model were analyzed and compared one another.
The results can be summarized as follows :
1. In sample ¥°, the stress was shown to have distributed uniformly throughout the
whole tooth even to the alveolar bone.
2. In sample ¥±, the transmission of stress from the crown to the root area was
shown to be very poor and irregular.
3. In sample ¥², the needle post was proved to be very effective in distributing the
stress well to the aveolar bone which might help in maintaining the stability of crown
restoration.
