Purpose The purpose of this clinical investigation was to evaluate full‐arch fixed‐dental restorations supported by immediate loaded axial and tilted implants in a single‐cohort study. Survival rate of axial and tilted implants was compared. Materials and Methods From 2006 to 2010, 30 patients were recruited and treated with dental implants. Provisional fixed‐dental prostheses were screw‐retained over axial or axial and tilted implants within 24 hours after surgery. Follow‐ups at 6, 12, and 24 months and annually up to 5 years were scheduled, and radiographic evaluation of peri‐implant bone level changes was conducted. Results Thirty patients (20 females and 10 males) were followed up for an average of 44 months (range 18–67 months). Six patients received both upper and lower implant rehabilitations, resulting in 36 restorations. A total of two hundred two implants were placed (maxilla = 118; mandible = 84) and 46% of the fixtures were evaluated at the 4‐year recall. Four axial implants were lost in three patients, leading to 98.02% implant (97.56% axial implants and 100% tilted implants) and 100% prosthetic cumulative survival rate, respectively. No significant difference in marginal bone loss was found between tilted and axial implants in both jaws at 1‐year evaluation. Conclusions Midterm results confirmed that immediate loading of axial and tilted implants provides a viable treatment modality for the rehabilitation of edentulous arches.
