CONCLUSIONS The use and positioning of Vario SR Abutments helps to stabilize the soft tissues at gingiva level due to the fact that the abutments will not be re- moved anymore once the provisional restoration is inserted. The passivation, first of the provisional and then the final restoration on the implants is supported by the conical characteristics of the Vario SR Abutments. This prevents any tension, which, if present, might be respon- sible for a prosthetic failure due to overload, even with correctly posi- tioned implants. I addition, perfect passivity insures the preservation of the aesthetics, short and long terms stability. The convenient removabil- ity of the screw retained prosthesis, if necessary, is possible without in- terfering with the gingival seal. The stability is granted by the screw retaining system: screws with ade- quate dimensions combined with a large number of threads and appropri- ate depth avoiding thus any friction or tension of the screw joint, grant- ing therefor the stability of the fixation. The possibility to remove the rehabilitation will provide inspection over time, either at prosthetic level or at the implant-prosthetic emergence. This applies as well to the professional hygiene recalls. This type of rehabilitation, on 6 implants, in accordance to the interna- tional literature shows great restorative efficacy in edentulous patients, in single ore both jaws. The correct positioning of the implants will help to preserve the marginal bone and simple routine maintenance of the res- toration for the patient to his greatest satisfaction.
