Purpose: To overcome the limitations of implant placement in Knife edge ridges, Summer introduced Osteotome technique in 1994. It has been claimed that bone condensing for preparation of the implant site in soft bone avoids the risk of heat generation and also implants can be placed precisely with increased primary stability. The purpose of this study was to analyze the use of the osteotome technique, followed by immediate implant placement, using cases presenting different conditions as dento-alveolar bony defects and to define management solutions in the event of existing bone resorption.

Material and Methods: A group of twenty patients treated with bone expansion by means of osteotome technique, followed by single immediate implant placement were placed either in the maxillary or mandibular regions. Clinical findings have been recorded (complications, infection, and wound dehiscence) during the whole follow up period. The amount of bone expansion at the alveolar ridge after implant placement was measured clinically, gingival margin was evaluated clinically, and the marginal bone resorption (crestal bone loss) were evaluated radiographically for the restored implant oneyear after implant’s functional loading.

Results: The surgical sites for the implant areas showed no post-operative complications, infection nor wound dehiscence during the whole follow up period. No prosthetic complications were recorded at follow up visits. The amount of bone expansion at the alveolar ridge were ranged 2.6-4.2 mm. The amount of marginal bone resorption from time of implant placement to one-year’s after implant’s functional loading were ranged 0.8-1.9 mm. The contour, height, and width of gingival at the implant site was corresponded to the soft tissues that surround the adjacent natural teeth) The gingival margin as esthetic outcome were achieved for most of the restored implants one-years after implant’s functional loading.

Conclusion: Based on the results of this study, the Osteotome technique is a good technique for the purpose it was introduced i.e. for Knife edge ridges and the advantages for this technique for patients include less surgical trauma and a shorter treatment time.
