Kohn conducted some biomechanical studies in the mandible of human corpses where displacement with resorbable PLLA/PGA screws and bicortical titanium screws were studied. Screws were subject to force exerted on a board; this exercise showed that there is no significant difference between both types of screws.
Algunos estudios biomecánicos de Kohn en mandíbula de cadáveres humanos se evaluó el desplazamiento con tornillos reabsorbibles PLLA/PGA y tornillos de titanio bicorticales donde fueron sometidos a fuerza sobre una viga, comprobaron que no existe una diferencia significativa entre los tornillos de titanio y los tornillos.
