CLINICAL A Relaxed Implant Bed: Implants Placed After Two Weeks of Osteotomy With Immediate Loading: A One Year Clinical Trial Jyoti Bansal, MDS* Suresh Kedige, MDS Abhishek Bansal, MDS Samir Anand, MDS 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. Key Words: early osteotomy with delayed implant placement, acceptable and relaxed implant bed configuration, immediate loading INTRODUCTION he ideal goal of lifelike restoration has helped nurture new vistas in the art and science of implant dentistry. The protocol of ‘‘restoration-driven implant placement’’ ensures that the implant is an apical extension of the ideal future restoration and Maharishi Markandeshwar University, Mullana, Ambala, India. *Corresponding author, e-mail: drjyo17@yahoo.co.in DOI: 10.1563/AAID-JOI-D-10-00036 T not the opposite. With the high predictability of osseointegration, the current trend is gearing toward the development of various implant placement protocols to enhance the patient’s function, esthetics, and comfort.1 The original Branemark implant protocol required a load-free and submerged healing to obtain predictable osseointegration to avoid the fibrous tissue encapsulation around the implant. However, recent research advocates precise preparation of the implant bed and adequate primary implant Journal of Oral Implantology 155
