Abstract
One-piece implants incorporate the trans-mucosal abutment as an integral part of the implant. One-piece implant are usually welded together and immediately loaded. Since few reports are available on the effect of welding on implant’ survival, a retrospective study is performed. Nineteen patients (10 females and 9 males) with a median age of 62 years (min-max 43-80) were enrolled. The mean follow-up was 7 months. A total of 176 one-piece implants (Diamond, BIOIMPLANT, Milan, Italy) were inserted. One hundred and thirty-eight implants were welded. Disease-specific survival curves were calculated according to the product-limit method. In our series SVR is 93.75. Kaplan-Meier algorithm demonstrated that welded implants have a statistical significant better survival than unwelded implants. In conclusion one-piece implants are reliable devices for oral rehabilitation (since they have a SVR = 93.75) and welding procedure reduce the number of lost implantsI documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
