| Title |
No Clinical or Statistical Difference Between Porcelain and Composite Restorations for Fractured Maxillary Incisor |
| Clinical Question |
In a patient with a maxillary anterior tooth fracture, would a composite restoration, compared to a porcelain veneer, provide a stronger restoration? |
| Clinical Bottom Line |
For a patient with a maxillary anterior tooth trauma fracture of 4 mm or less, there is no statistically significant difference in the fracture resistance between a composite restoration and porcelain veneer. The composite restoration and porcelain veneer are clinically acceptable treatments, but treatment decision would depend on esthetics and cost. |

| 21752192 | Batalocco/2012 | 60/ human-extracted maxillary central and lateral incisors | Controlled in-vitro trial | | Key results | The composite veneers of the 2 mm fracture group demonstrated a mean failure load of 1386.59 N ± 712.16 while the 4 mm fracture group demonstrated a mean failure load of 1322.61 N ± 716.16. The porcelain veneers of the 2 mm fracture group demonstrated a mean failure load of 1039.29 N ± 592.96 while the 4 mm fracture group demonstrated a mean failure load of 1459.21 N ± 910.25. | |

Comments on
The Evidence |
Validity: This article is a controlled and presented a comprehensive and detailed description of their respective materials and methods. The trials tested the results for validity by comparing the findings to known values. Although the 2 experimental groups, composite and porcelain, technically were prepared differently, the 2 groups were prepared using clinically established and accepted methods. The veneer was prepared without a palatal extension while the composite was prepared with a palatal extension with a bevel. |
| Applicability |
Anterior maxillary trauma fracture restored with either a composite restoration or porcelain veneer. |
