Effect of screw access hole design on the fracture resistance of implant ‐supported zirconia‐based restorations

ConclusionsThe screw access hole decreased the fracture resistance. A surrounding zirconia wall for the screw access hole increased the fracture resistance. Clinical SignificanceScrew access hole design may affect the fracture resistance of cement ‐retained implant‐supported zirconia‐based restorations with screw access holes. This study introduced a screw access hole design to improve the fracture resistance of these restorations.
