Abstract: Presented herein are methods and devices for designing dental components, such as physical models of a patient's anatomy, crowns and bridges. An operator of a prosthetic designing system can receive information, such as from a scanner, which provides information on the topology of the patient's dentition. The operator can use this information to design a custom prosthetic to fit the patient. Part of the designing process involves using a finish line defined for a preparation as a segmentation line for a physical die corresponding to the preparation, and using a path of draw line as an insertion axis line for a dental prosthetic.

Abstract: A method of preparing a blood platelet lysate starting from platelet-rich plasma from whole blood of animals, to which blood a citrate has been added to prevent coagulation, is described. The method is characterised by concentrating the platelet-rich plasma by ultrafiltration to obtain a plasma that is richer in platelets, adding water for lysis of the platelets included, adding Ca2+ to the lysed concentrated platelet-rich plasma for forming coagel of other components than lysed platelets, centrifuging the coagel, whereby a clear, bright-red liquid of blood platelet lysate is obtained, which substantially consists of lysed platelets, and a coagulate, and, after centrifugation, the liquid going through a filtering step.
