It has been referred to as a second-generation platelet concentrate, which has been shown to have several advantages over traditionally prepared PRP. It’s a new generation of platelet concentrates geared to simplified preparation without biochemical blood handling. This article describes the evolution of this novel platelet concentrate and its applications in the field of Oral and Maxillofacial Surgery.

Materials and Methods Two popular instruments Obwegesser's pterygoid and shark-fin osteotome were tested on dry human skulls. The external force required for separation of the pterygomaxillary suture with these osteotomes was generated by an electronically controlled 'Instron' tester Bi-06-108. Tests were performed with pterygoid osteotome placed on one randomly chosen side and sharkfin osteotome on the other side of the same specimen. The amount of strain developed by each of these instruments was recorded using two strain gauges on the right and left lateral pterygoid plates. Results Instrument used Mean force to achieve dysjunction Mean strain developed Pterygoid osteotome 169 N 887.66 microstrain Shark-fin osteotome 175.5 N 677.33 microstrain Conclusion Based on the distribution of strain, from this study, we conclude that Laster shark-fin osteotome is efficacious over Obwegeser's Pterygoid osteotome, in Le fort I osteotomy.
