A dental implant abutment is a device screwed to the dental implant and in permanent contact penetrating the gingival tissue. MetAlive® treated abutments are sold worldwide by DESS and Into Dental in Finland.
Of all MetAlive® indications, the dental implant abutment is surely one of the most clearly justified. The attachment of cells and of both gingival epithelium and connective tissue bring advantages at all healing stages. MetAlive® achieves Fast and immediate attachment of cells on the abutment surface Faster generation of tissue through a greater proliferation rate of cells Closing of the gingival tissue wound also at the abutment interface, alongside the natural tissue wound closure Faster healing of the tissue at every stage of healing Greater contact area between the tissue and abutment surface (biological width) Reduction of encapsulation Reduction of bone resorption during the healing period Improved soft tissue closure of the infection gate At a histological level, the difference between the MetAlive® abutment and an ordinary abutment can be seen. Due to histological preparation techniques, the contact between a normal abutment surface and the gingival tissue has been lost and a clear gab is observed. In real life the gingival tissue is likely to have good contact with the abutment, but the strength of the interface is so low that the smallest mechanical trauma can detach the gingiva, thus opening the infection gate. On the MetAlive® abutment the gingival tissue is in perfect contact and has retained its normal structure despite the preparation. This is yet another piece of evidence strengthening our perception of significant clinical value Metalive® can offer. See video below.
Metalive achieves strong biological adhesion with gingival tissue. When gingival tissue is detached by force from the abutment, the failure occurs usually within the tissue as cohesive rupture. Proof of this is that tissue remnants are observed on the abutment surface after removal.
