A relaxed implant bed: implants placed after two weeks of osteotomy with immediate loading: a one year clinical trial.

A waiting period of 2 weeks after osteotomy increases the surrounding tissue activity to its maximum level as collagen formation and neoangiogenesis represent a relaxed and acceptable implant bed configuration. The aim of the present study was a clinical and radiologic evaluation of early osteotomy with implant placement delayed for 2 weeks with immediate loading in the anterior and premolar region with minimally invasive approach. Seven GS II implants (Osstem) were placed in 6 patients. Osteotomy was done followed by flap closure without placement of the implant. After waiting for approximately 2 weeks, implant placement was done, which was loaded immediately with provisional crown in implant protected occlusion. It was replaced by definitive restoration after 6-8 weeks, which was considered baseline. Implant stability and marginal bone levels were assessed with clinical and radiologic parameters at baseline, 6- and 12-month intervals. None of the implants were found mobile during the 1-year period. The average mean marginal bone loss was 0.4 mm over the 1-year follow-up period. In the present study, early osteotomy with delayed implant placement showed negligible crestal bone loss with no mobility.
