Dental implant placement at the atrophic posterior mandible carries a risk of Inferior Alveolar Nerve (IAN) damage and permanent facial paresthesia. Currently, available treatment options are associated with higher long-term failure rates or involve surgically complex techniques with high surgical failure rates, significant risk for IAN damage and prolonged healing period . Hypothesis The proposed novel treatment technique can serve as an alternative treatment approach with higher immediate and long-term success rates while implemented in a minimally invasive approach. Objectives Describe and evaluate the safety of the treatment and the long-term success rates of novel implantation method. Results Fourteen dental implants were placed at the atrophic posterior mandibular region of nine patients. Follow up period of post implant placement, exposure and rehabilitation ranged from 1 to 6 years. During follow up period all implants were well osseointegrated with 1-2 weeks of healing period. Furthermore, there was no implant failure or evidence of inferior alveolar nerve damage. Conclusions Computer-Guided dental implant placement at the atrophic posterior mandible can serve as an alternative treatment method. This method can be implemented in a safe and minimally invasive approach and associated with higher success rates then currently available treatment methods. Further research on larger study groups is required in order to evalute the safety and the short and long term succsses rate of this novel treatment technique.
