A non-randomized comparative usability pilot study conducted at the University Hospital of Basel, Switzerland.
A rigorous, standardized protocol designed to objectively compare two bone harvesting instruments under controlled clinical conditions.
BoneGainer demonstrated statistically significant superiority over the conventional Safescraper in every measured category.
BoneGainer demonstrated significantly improved ergonomic performance, reducing operator fatigue and enabling more controlled surgical movements throughout the procedure.
The replaceable blade mechanism maintained consistent cutting behavior throughout procedures, eliminating the performance degradation seen with conventional instruments.
Increased user satisfaction was observed across all experience levels — from trainees to experienced oral surgeons — confirming broad clinical applicability.
Cohen effect size values of r = 0.82 – 0.86 confirm very large clinical relevance per established statistical classification, substantiating the practical significance of the findings.
The study demonstrates significantly improved ergonomic performance, consistent cutting behavior, and increased user satisfaction. BoneGainer presents itself as a clinically validated and functionally effective solution for autologous bone harvesting.
