Güncel post materyallerinin( PEEK,fiber, döküm metal )farklı ferrule koşullarında kırılma dayanımlarının incelenmesi

Aim: The

fracture resistance of the post materials used nowadays significantly

impacts the fracture type of the post material. The current study aimed

to examine the impact of the fracture resistance of PEEK posts, whose

use as a post material has not yet become widespread, on the fracture

pattern that will occur. Materials and Methods:

Sixty-six extracted upper central incisor human teeth were used in the

study. Six groups of posts were produced from metal, fiber, and PEEK

materials (n = 11). Afterward, the fracture resistance test was applied

to the samples. Samples were classified according to fracture type as

repairable or irreparable. The ANOVA and test were used in statistical

analysis. Post-hoc tests were carried out using Tukey’s and Tamhane’s T2

tests. On the other hand, Pearson’s chi-square test and the

Fisher-Freeman-Halton test were conducted for comparisons between

categorical variables. The statistical significance level was accepted

as p < 0.05. Results: According to the fracture

resistance test results, the groups where metal personal posts were used

displayed higher fracture resistance in comparison with all other

groups. According to the results of the optical microscope examination,

the incidence of repairable fractures was significantly higher in the

PEEK post group with ferrule preparation (p < 0.05). No significant

difference was identified between the fiber and PEEK post groups with

ferrule preparation (p > 0.05). Conclusion: In the

absence of the ferrule effect, fractures are catastrophic, regardless of

the material used. The use of PEEK as a post material contributes to

keeping fractures at a repairable level.
