Objectives. This prospective study evaluated the survival rate and the implant-crown success of single-tooth titanium dental implants produced with direct laser metal forming (DLMF) after 1 -year of functional loading. Materials and methods. 110 maxillary (N = 65) and mandibular (n = 45) implants (TixOs®, Leader Novaxa, Milan, Italy) were placed in 82 patients (44 males, 38 females; age range 26-67 years) in 7 different clinical centers. The prosthetic restorations included 110 single crowns (SCs) (32 anterior, 78 posterior). The scheduled 1-year follow-up examination focused on several clinical, radiographic, and prosthetic parameters. Implant success was defined as the absence of pain, sensitivity, suppuration, and exudation; absence of clinically detectable implant mobility; absence of peri-implant radiolucency; distance between the implant shoulder and the first visible bone contact (DIB) < 1.5 mm; absence of prosthetic complications at the implant abutment interface. Results. After 1 -year of functional loading, the overall implant survival rate was 99.1% (98.4% maxilla, 100% mandible). The mean DIB was 0.60 mm (± 0.32). All but 3 of the 109 surviving implants fulfilled the implant-crown success criteria (implant-crown success 97.2%). Conclusions. Titanium dental implants produced with DLMF seem to represent a valid treatment option for single-tooth restorations in the maxilla and in the mandible. Further studies are needed to evaluate the long-term performance of these implants. © 2011 Bsevier Srl.
