Comparison of four bone collectors designed for oral and maxillofacial surgery--an in vitro study

Four bone collectors designed for oral and maxillofacial surgery were compared in an in vitro study. Two commercially available bone collectors (Osseus Coagulum Trap, Quality Aspirators and Frios, Friatec) with mesh sizes of 0.17 x 0.17 and 0.44 x 2.40 mm, respectively and models developed by the authors with mesh sizes of 0.355 x 0.355 or 0.50 x 0.50 (Model I) and 0.80 x 0.80 (Model II) were tested. All collectors are designed to be connected to the suction device. Five dissected pig mandibles were used to determine the harvesting capacity during drilling and suctioning for 30 s. All collectors harvested bone quite effectively, but the highest amount of bone chips was harvested by Model I which had been designed by the investigators.
