Load-bearing capacity of screw-retained zirconia crown-abutment complexes of different heights fabricated by additive and subtractive methods after cyclic loading: An in vitro study

Why it matters for dental
Prosthodontists and implant teams who restore zirconia screw-retained crowns need to know whether 3-D-printed versus milled abutment-crown complexes of varying heights will survive long-term cyclic loading before changing workflows or inventory.
Key points
- In-vitro study compares additive vs. subtractive zirconia fabrication on load-to-failure after simulated mastication.
- Crown-abutment height is a tested variable; clinicians will see which heights retain adequate fracture resistance.
- Results due 23 July 2026 in The Journal of Prosthetic Dentistry; no interim data released.
- Findings could shift material purchasing and lab prescriptions for single-implant zirconia restorations if one method shows superior durability.
