The effect of resin cements and primer on retentive force of zirconia copings bonded to zirconia abutments with insufficient retention.

Kim SM, Yoon JY, Lee MH, Oh NS - J Adv Prosthodont (2013)

Bottom Line: Superbond C&B groups (S & SZ) showed significantly higher retentive force than Panavia F2.0 groups (P & PZ).In Panavia F2.0 groups, the use of primer was found to contribute to the increase of retentive force.On the other hand, in Superbond C&B groups, the use of primer did not influence the retention forces.

ABSTRACT

Purpose: The purpose of this study was to investigate the effect of resin cements and primer on the retentive force of zirconia copings bonded to zirconia abutments with insufficient retention.

Materials and methods: Zirconia blocks (Lava, 3M ESPE, St. Paul, MN, USA) were obtained and forty sets of zirconia abutments and copings were fabricated using CAD/CAM technology. They were grouped into 4 categories as follows, depending on the types of resin cements used, and whether the primer is applied or not:Panavia F2.0 (P), Panavia F2.0 using Primer (PRIME Plus, Bisco Inc, Schaumburg, IL, USA) (PZ), Superbond C&B (S), and Superbond C&B using Primer (SZ). For each of the groups, the cementation was conducted. The specimens were kept in sterilized water (37℃) for 24 hours. Retentive forces were tested and measured, and a statistical analysis was carried out. The nature of failure was recorded.

Results: The means and standard deviations of retentive force in Newton for each group were 265.15 ± 35.04 N (P), 318.21 ± 22.24 N (PZ), 445.13 ± 78.54 N (S) and 508.21 ± 79.48 N (SZ). Superbond C&B groups (S & SZ) showed significantly higher retentive force than Panavia F2.0 groups (P & PZ). In Panavia F2.0 groups, the use of primer was found to contribute to the increase of retentive force. On the other hand, in Superbond C&B groups, the use of primer did not influence the retention forces. Adhesive failure was observed in all groups.

Conclusion: This study suggests that cementation of the zirconia abutments and zirconia copings with Superbond C&B have a higher retentive force than Panavia F2.0. When using Panavia F2.0, the use of primer increases the retentive force.

Mentions: Fig. 4 shows the surface of the zirconia before and after primer application. A relatively even film formation is visible on the zirconia surface after use of the primer. All of the fracture failure modes demonstrated adhesive failure (Fig. 5). Some of cement remained in 1/3 of the cervical area of the zirconia abutments, while the rest remained within the zirconia copings.
