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.

Aims : the study aims is to examine the inter- observer variability in radiographic interpretation of the variable position , shape and appearance of mental foramen. Materials and Methods: Four examiners, two dental radiologists and two oral surgeons evaluated 30 panoramic radiographs to evaluated the position, shape and appearance of mental foramen. Results: The most frequent position of mental fo-ramen was between first and second premolars then followed by those below the apices of the first and second premolars and the most frequent shape of mental foramen was irregular where separated type is the frequent appearance of mental foramen. For agreement there was no significant difference between two radiologist for position ,shape and appearance of mental foramen , but with a significant difference was found between four observer, for the position of mental foramen. Conclusions: The study concluded that the position of mental foramen is most commonly below and between the pre-molar teeth and the most frequent shape are irregular and appearance separated type

Radiographic evaluation of mental foramen on the panoramic radiography

The appearance and the location of the mental foramen have been evaluated on the panoramic radiograph of(83) adult patients with complete dentition. The most frequent appearance was a separated type of mental foramen(50.61%) followed by continuous(24.09%), diffuse(19.28%) and unidentified type(6.02%). The most common location of mental foramen in relation to the lower bicuspid teeth was below the apex of second premolar(53.85%), and it lied lower than the midway between the upper and lower border of the body of the mandible, and some what it lied at one third of distance from the mandibular symphysis to the posterior border of the ramus of the mandible.
