Lateralization of the Inferior Alveolar Nerve After Repositioning of the Bone Window Versus Sticky Bone Augmentation

Egypt20 participantsStarted 2018-10-25

Plain-language summary

Rehabilitation of edentulous posterior mandibular regions with severe ridge atrophy using implants is subject to anatomical, surgical, and biological difficulties. In many cases, the bone is severely atrophied that sufficiently long fixtures cannot be placed without encroaching on the inferior alveolar nerve (IAN). IANL is defined as the lateralization of inferior alveolar neurovascular bundle posterior to the mental foramen, with preservation of the incisive nerve; exposure and traction are used to deflect the IAN laterally while the implants are placed.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients suffering from unilateral posterior mandibular edentulism and having \< 8 mm of bone above the mandibular canal. * The width of the ridge should be \> 4mm. * The patient should be psychologically accepting the implant and the involved procedures. * The patients should have adequate oral hygiene and adequate bone quality. Exclusion Criteria: * Any absolute contraindication for implant surgery such as uncontrolled diabetes mellitus, blood and/or bleeding disorders, serious osseous defects…etc. * Any relevant systemic disease directly affecting bone metabolism and healing. * Any habits that might reduce the blood flow and retard healing such as heavy smoking and alcoholism. * A history of any grafting procedure at the designated area. * Patient with thick cortical bone buccally and a thin neurovascular bundle.
