What is it about?
We measured the fracture strength of titanium insert-reinforced zirconia abutments fabricated by varying the axial height of the titanium insert and the labial height of the zirconia abutment to suggest an ideal titanium insert axial height in terms of the integrity of the abutment–implant complex.

Why is it important?
The positive effect of the titanium insert was demonstrated by the higher flexural strength of the internal connecting type. However, the use of a titanium insert-reinforced zirconia abutment could lead to the zirconia prosthesis becoming fractured or dislodged.the axial height of the titanium insert could determine the surface area bonded to the zirconia abutment and varies depending on complicated clinical conditions. However, there are few studies in the literature that can provide guidelines for the fabrication of titanium inserts.
Perspectives
I think this journal will be a useful guide for those who need aesthetic and high-strength zirconia implant abutments.
