Abstract
One-piece implants became more and more popular in the last few years. They incorporate the trans-mucosal abutment as an integral part of the implant. Since no report specifically focus on one-piece implants inserted in mandible is available, a retrospective study was performed. Eleven patients (7 females and 4 males) were enrolled in the present study. A total of 93 one-piece implants (Diamond, BIOIMPLANT, Milan, Italy) were inserted. Cox analysis was used to detect if any of the studied variables (i.e. diameter, length, replaced tooth position and welding) has an impact both on failures (SVR, i.e. lost fixtures) and/or on success (SCR, i.e. crestal bone resorption around implants lower than 1.5 mm). In our series SVR and SCR were 100 (i.e. no implant lost) and 97.8 (i.e. 2 failed implants), respectively. Cox analysis demonstrated that no studied variables (i.e. diameter, length, replaced tooth position and welding) have direct impact on survival (i.e. lost implants) as well as on clinical success (i.e. crestal bone resorption) (p > 0.5). In conclusion one-piece implants are reliable devices for mandible rehabilitation.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
