This study investigates the effects of inferior alveolar nerve lateralization on the post-implant insertion sensory outcome for patients with severe mandibular bone resorption.

This is a prospective randomized clinical trial. The study was carried out in patients with posterior mandibular atrophies among selected cases from patients attending the Faculty of Dentistry dental polyclinics, and some private dental clinics in Sana'a city The age of patients was above the age of 18 years All patients received a thorough dental examination (extra-oral and intra-oral examination) in dental clinics using a dental mirror, ball-tipped World Health Organization (WHO) dental prob, and dental tweezers. Sterile examination tools by autoclave class B were used. Clinical examination included Oral health and oral hygiene status, interarch distance, dimensions of the edentulous ridge, and soft tissue condition. Panoramic radiographs were taken to assess the condition of the patients' teeth and jawbone, as well as to detect any oral infections requiring treatment. Surgical procedures are performed to translocate the inferior alveolar nerve to provide a good space for implant insertion. All cases ahs undergone follow-up for post-surgical sensory disturbances.
