Volumetric comparison of three different innovative bone collecting devices for autogenous bone grafts.

Objective: The aim of this study was to evaluate the clinical relevance of three different bone collecting devices in a volumetric comparison. Method and Materials: Bone harvesting for the collection of bone particles was performed on bovine mandibles. Three different types of bone collecting devices (Tests 1, 2, and 3) were used. Ten drilling sites in each group were prepared and bone particles were collected. Bone particles were sieved twice in sieves with 500 pm and 1,000 pm openings. The bone particles were divided into three groups: < 500 pm (SP), 500-1,000 pm (MP), and >1,000 pm (LP). Total wet volume, fractional wet volume, fractional dry volume, and weight were measured. The shape of the dried particles was examined using a microscope. Results: All particles in all three groups had a wood shaving-like appearance. With Test 1 and Test 2, LP were the most common (0.510 ± 0.064 mL, 0.430 ± 0.067 mL), and in Test 3, MP was the most common (0.112 ± 0.019 mL). Among the SP and MP, the wet volume of Test 3 was significantly greater than those of Tests 1 and 2 (P < .001). However, among the LP, the wet volume sequentially increased from Test 1, to Test 2, and Test 3 (P < .001). The proportion of dry volume was similar to that of wet volume. Conclusion: Three innovative bone collecting devices could collect comparable amounts of bone particles to commercially available bone graft materials. [ABSTRACT FROM AUTHOR]
