difference between the groups was not statistically significant (p = 0.77)

Support of all placed implants, extended to the first molar region, not need to be reduced from the day of delivery to the final follow-up

Prosthetic screw loosening and abutment fractures. All unsuccessful prosthetic events occurred in the first year, with the majority experienced by the oncologic group. 5-year follow-up complication probability values were 10.7% [95% CI 4.1–26%] for the atrophic group, and 10.7% [95% CI 3.5–29.6%] for the oncologic group
