Challenge Skills Criteria for Dental Implants Success in Inferior Alveolar Nerve Lateralization and Transposition

Abstract

Objectives: direct the surgeons to solve the problem of insufficient posterior alveolar ridge height for successful dental implants.Materials and Methods: Case series: Four patients underwent inferior alveolar nerve translocation operation with dental implant, One male and 3 females. Intervention and outcome: Cases divided to 2 groups, group A in which surgery done under local anesthesia were the bony windows not involve the mental nerve (the window done distal to mental nerve). Group B underwent surgery under general anesthesia with bony window involve mental nerve. Result: Survival rate of the I.A.N. were 100% with 9 succeed dental implants inserted with the translocation of the nerve. Fixed prosthesis delivered with good satisfaction of these patients. Parasthesia extend between 3 weeks up to 8 weeks with complete recovery after 6 months. Patients followed for 6 years. Conclusion: IAN Lateralization and Transposition is the most appropriate choice for dental fixture replacement in atrophied posterior mandible rather than other choices as bone augmentation or short implants. Although skill, precise and experience challenges must available in the surgeon for optimal and long term success result. Avoidance of permanent injury to the IAN should be avoided by accurate clinical and radiographical examination. Patient choice for local or general anesthesia has no effect on surgeries itself.
