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

Inferior Alveolar Nerve Clinical Trial

Official title: Lateralization of the Inferior Alveolar Nerve After Repositioning of the Bone Window Versus Sticky Bone Augmentation: A Randomized Controlled Clinical Trial

Status Completed

Clinical Trial 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.

Clinical Trial Description

This prospective randomized clinical trial will enroll 20 patients with posterior mandibular ridge atrophy. Ten of which will undergo computer guided nerve lateralization with subsequent implant placement and repositioning of the osteomotized bone window and ten patients will undergo computer guided nerve lateralization with subsequent implant placement and sticky bone grafting. ;
