RESUMO

Differents drafts of tooth implant insert differents levels of tension in the surrounding bones. This can results in differents prognostics for the implants installed. This work considered by photoelasticity (resilience) of the circuit transmission the gradient of tensions produced in near pre-ordered of the implants when installed in photoelasticity matrix. Eight points were considered when no burden and thirteen points when submited to the axial burden of 0,30N, testing the hypothesis that the tension is the same at the differents implants. The implants used were Titamax TI Medular, Titamax TI Cortical, Titamax Cone Morse and Alvim TI (Neodent, Curitiba, Brazil). The value of the midle cutting tension between the analysed points of each group was submited to the variant analyse showing that has a suggestive statistic difference (p<0,05) between the unburden group. In this situation the Tukey test showed where the difference was. The results outpointed that between the tested implants, the one that produced more medium tension after the installation was the Alvim TI and the axial burden incidence did not result in significative difference at the medium tension produced for all the groups. This work objective was to estimate, in photoelasticity analyse, the tension produced by differents drafts of implants after their installation and after burden incidence, testing the hypothesis that the tension is the same in the differents kinds of implants.
