Background: The routine and frequent use of dental implants to replace missing teeth is accompanied by high expectations from patients. These expectations are not limited to function and esthetics but extends to patient comfort and time spent in receiving treatment. Replacement of an unrestorable maxillary premolar can be challenging when considering the concerns of patients. A one‑piece implant (OPI) incorporates the trans‑mucosal abutment facing the soft tissues as an integral part of the implant. Since no report specifically focused on OPIs inserted in premolar areas, a retrospective study was carried out.

  Materials and Methods: Nineteen patients (10 females and 9 males) with a median age of 62 years (43‑80) were enrolled and a total of 176 OPIs (Diamond, BIOIMPLANT, Milan, Italy) were inserted.

 Results: In our series survival rate (SVR) and success rates (SCR) were 90.6% and 97.9%, respectively. Statistical analysis demonstrated that no studied variable had an impact on survival (i.e., lost implants) as well as on clinical success (i.e., crestal bone resorption).

 Conclusion: OPIs are reliable devices for oral rehabilitation in the premolar areas.
