Comparative histological and biomechanical assessment of MDR titanium dental bone implants in the shape of a tapered screw and coated in titanium according to the vacuum plasma spray method
The trial was carried out with the purpose of performing a biomechanical and histological assessment of the tipped, tapered dental implant.At the same time a comparative assessment was carried out, with particular focus on the bone/implant interface on three different surface kinds (machines STi titanium, vacuum plasma spray VPS, fluorohydroxyapatite FHAVS).
The trial produced the following outcomes:
- radiography analysis did not outline any trace of bone rarefaction in any of the implanted screws.FHAVS coated implants displayed bone growth around and over the whole implant, with a significant thickening of the cortical bone.VPS-treated implants, too, did the same, though to a lesser extent.
From a biomechanical standpoint there is evidence of complete osseointegration.
