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.

Exclusion Criteria:
Device: Dental implant
insertion of dental implants after surgical tranlocation of the inferior alveolar nerve.
Cone-beam Computed Tomography (CBCT)
visualize the inferior alveolar canal (IAC) and assess the proximity of the implant to the nerve
Time frame: The implant's success rate was determined by primary stability during insertion, assessed by ratchet, and then confirmed by X-ray. CBCTs were taken at 3 months and 4 months after implant insertion to check for marginal bone loss.
Subjective Function Score
Patients rate their perceived sensory function relative to an unaffected area, providing a measure of functional impairment.
Time frame: Neurosensory evaluation was carried out on the 1st and 7th postoperative day and every month thereafter for up to 6 months.

Ran from Jun 2024 to primary completion in Apr 2025, 10 months.
Of 82 non-industry interventional studies with no phase under Bone Resorption, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 35. This study's 10 months is below that.
Counting every sponsor, half of 83 studies reached it within 23 months; a quarter within 12 and three quarters within 35.
