Histology. “In vivo” studies.       Various histomorphometric studies have been carried out. They all have shown (See tables below): Higher osseointegration level on Lifenova’s surfaces in comparison to untreated titanium, Ti6Al4V and several commercial surfaces. An accelerated osseointegration. Details of those studies can be found in: Comparative histomorphometric study of five different dental implant surface treatments in Beagle dogs.
