12. A fixture range or system for Osseo distraction, or for orthodontic anchorage in a jaw, having available matched components, provided with fittings to facilitate the connection of arch wires, or the cementation of orthodontic components.
-
13. A fixture as claimed in claim L having a surface treatment intended to encourage rapid osseointegration, wherein said surface treatment comprises plasma spray, etching, blasting, titanium dioxide, hydroxyl-apatite or other roughening processes, on only the more superficial endosseous part of the fixture which is intended to contact the bony cortex of the intended site, and a smoother, possibly machined surface towards the apical portion of the fixture.
-
14. A fixture as claimed in claim L having a progressively rougher surface, which is relatively smooth toward the apex of the fixture, and which becomes relatively rougher, and more attractive to bone growth towards the coronal aspect of that part of the fixture which is intended to contact the bony cortex of the intended site.
-
15. A range or system of components for Osseo distraction, or for orthodontic movement of teeth, provided with fittings to facilitate the connection of arch wires, or the cementation of orthodontic components, wherein said range or system of components is arranged to be used in conjunction with a fixture having an externally threaded intra oral part or a threaded and flattened intra oral part.
