Objectives A 3‐year proof‐of‐principle study was initiated to evaluate the clinical efficacy of immediately loading titanium dental implants with surfaces enhanced with porous tantalum trabecular metal ( PTTM ). First‐year interim results are presented. Materials and Methods Healthy, partially edentulous patients ( n = 30) were enrolled and treated per protocol (minimum insertion torque: ≥35 Ncm) with 37 implants placed in one or two premolar or molar locations in either jaw (study group). Implants were immediately provisionalized out of occlusion with single acrylic crowns. After 7 to 14 days of soft tissue healing, implants were definitively restored in occlusion with ceramometal crowns. Because most study group implants (54.1%, n = 20) had less than 1 year of clinical follow‐up, this interim analysis was limited to the first 22 consecutively placed implants in 17 subjects (10 women and 7 men) who completed 1 year of clinical follow‐up to date (focus group). Results To date, one implant failed to integrate in the study group (survival = 97.3%, n = 36/37). Focus group implants achieved 100% ( n = 22/22) survival with 0.43 ± 0.41 mm of mean marginal bone loss. There were no serious complications. Conclusion Early clinical findings indicated that immediate loading of PTTM implants was safe and effective under the controlled study conditions.
