In your opinion, what is the difference between a good and a bad implant? What would the perfect implant be like?
In my opinion, the difference between a good and a bad implant is the type of titanium used in their manufacture, the surface treatment, as well as the quality of the prosthetic elements.
To me, the perfect implant would have a slight antibacterial neck, so that there would not exist bacterial aggregation, micro-coils in the first 2 mm and the remaining coils would be self-tapping.
The implant would be practically cylindrical, with anti-rotational grooves, rounded apex and morse taper. The surface treatment should result in an osteoinductive implant. The perfect implant should also have many prosthetic solutions, in order to be able to manage rehabilitations similar to the natural tooth.
