Comparison of Ribbond and Everstick Post in Reinforcing the Re-attached Maxillary Incisors Having Two Oblique...

This study aims to compare the resistance to fracture in maxillary incisors which were fractured in two different oblique patterns and then were re-attached and reinforced using anatomic fiber-reinforced composite (FRC) post.

Sixty extracted and intact human maxillary incisors were obtained and divided into two groups (A and B; n = 30). "Labiopalatal" and "palatolabial" fractures were induced in group A and group B, respectively. These two groups were further subdivided into two subgroups (n = 15). In subgroup I Ribbond fiber (Ribbond Inc., Seattle, WA, USA) and in subgroup II Everstick post (everStick Post™, GC Corporation, Tokyo, Japan) were used. Fractured fragments were re-attached using resin and tested for fracture resistance in universal testing machine. Statistical analysis was done with ANOVA one-way test and post hoc test.

The labiopalatal fracture pattern of group A showed significantly increased resistance to fracture than the palatolabial fracture pattern of group B in both the subgroups. Similarly, subgroup II with Everstick post exhibited significantly higher fracture resistance than subgroup I with Ribbond in both groups A and B (p value < 0.05).

The study simulates a clinical scenario of coronal fracture of a tooth and focuses on the techniques and materials which can be used for successful management of such cases.
