Implant angulation and fracture resistance of one-piece screw-retained hybrid monolithic zirconia ceramic restorations.

ABSTRACT:

Objective

This study aimed to investigate the fracture resistance of one-piece screw-retained hybrid monolithic zirconia ceramic restorations in different implant angulations.

Materials and methods

Three implant fixtures were embedded in acrylic resin blocks with 0°, 15°, and 25° angulations. For each group of implant angulations, 11 screw-retained one-piece monolithic zirconia restorations were made and bonded to the titanium inserts with a dual-cure self-adhesive resin. The complexes were screwed to the implant fixtures with titanium screws. The samples were thermocycled, subjected to compressive load, and fracture modes were recorded. One-way ANOVA and post hoc Tukey's test were used for statistical analyses (α = 0.05).

Results

One-way ANOVA showed the fracture res
