Early loading after 21 days of healing of nonsubmerged titanium implants with a chemically modified sandblasted and acid-etched surface: two-year results of a prospective two-center study.
PURPOSE The aim of this two-center study was to evaluate screw-type titanium implants with a chemically modified , s and blasted and acid-etched surface when placed in the posterior maxilla or m and ible , and loaded 21 days after placement . MATERIAL AND METHODS All 56 patients met strict inclusion criteria and provided informed consent . Each patient displayed either a single-tooth gap , an extended edentulous space , or a distal extension situation in the posterior m and ible or maxilla . Eighty-nine dental implants  ( SLActive , Institut Straumann AG , Basel , Switzerl and ) were inserted according to an established nonsubmerged protocol and underwent undisturbed healing for a period of 21 days . Where appropriate , the implants were loaded after 21 days of healing with provisional restorations in full occlusion . Definitive metal ceramic restorations were fabricated and positioned on each implant after 6 months of healing . Clinical measurements regarding soft tissue parameters and radiographs were obtained at different time points up to 24 months after implant placement . RESULTS Of the 89 inserted implants , two ( 2.2 % ) implants failed to integrate and were removed during healing , and two ( 2.2 % ) additional implants required a prolonged healing time . A total of 85 ( 95.6 % ) implants were therefore loaded without incident after 21 days of healing . No additional implant was lost throughout the study period , whereas one implant was lost to follow-up and therefore left unaccounted for further analysis . The remaining 86 implants all exhibited favorable radiographic and clinical findings . Based on strict success criteria , these implants were considered successfully integrated 2 years after insertion , result ing in a 2-year success rate of 97.7 % . CONCLUSION The results of this prospect i ve two-center study demonstrate that titanium implants with a modified SLA surface can predictably achieve successful tissue integration when loaded in full occlusion 21 days after placement . Integration could be maintained without incident for at least 2 years of follow-up
