Resumen

SANCHEZ, Johana et al. Compressive resistance of teeth with large conducts restored with two techniques. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2018, vol.11, n.1, pp.20-23. ISSN 0719-0107.  http://dx.doi.org/10.4067/S0719-01072018000100020.

Objective:

To compare the compressive strength of single-rooted premolar teeth, treated endodontically and restored using the monoblock technique and complementation.

Materials and methods:

45 single-rooted inferior premolars were selected, which were randomly distributed in 3 groups, 2 according to the reconstructive design: monoblock and complementation; the third group, restored under the cast core technique, was used as a control group. To determine differences in fracture resistance, we performed an analysis of Variance (One-way ANOVA) and post hoc Bonferroni test

Results:

The mean resistance was higher in the group rehabilitated with the conventional technique, followed by the monoblock technique, and thirdly the technique of complementation with the lowest value. However, the monoblock and complementation techniques exhibited similar strengths.

Conclusions:

Restored teeth with cast posts have a greater resistance to fracture than restorations with prefabricated posts, glass fibers with complementation and monoblock techniques. However, they produce more non-repairable or poor prognostic failures than restored teeth with prefabricated glass fiber posts for their elastic modulus.
