Objective: To describe a simple drilling technique to simultaneously place implant in horizontally deficient anterior maxilla.

Study design: A horizontal bone defect was noticed in a 20-year-old male with two missing maxillary middle incisors. We used a step-by-step drilling technique to prepare the implant site, during which the drill preparing directions was corrected step by step to the final ideal direction. Then the implants were placed and bone grafting materials were used in undercut for guided bone regeneration. After 6 months the implants was restored and followed for 2 years by cone beam CT.
Results: Clinical and radiograph evaluation revealed new bone formation at the labial side of anterior maxilla. Final crowns were restored and the new bone formation demonstrated a stable situation during the 2 year follow-up.

Conclusion: This step-by-step correcting direction technique can be used as an alternative procedure to overcome the horizontal bone defect in anterior maxilla.
