Impact of Mandibular Canal Trajectory on Paresthesia After Inferior Alveolar Nerve Lateralization

Evaluating the Influence of Mandibular Canal Trajectory on the Duration of Postoperative Paresthesia in Patients Undergoing Inferior Alveolar Nerve Lateralization: A Prospective Cohort Study

This prospective cohort study aims to investigate the relationship between mandibular canal trajectory and the duration of postoperative paresthesia in patients undergoing inferior alveolar nerve lateralization. The study will assess mandibular canal trajectory using anatomic factors and evaluate nerve sensory function using subjective and objective tests. Implant success criteria will also be assessed. The study will be conducted on patients who underwent IANL due to mandibular atrophy and were unable to receive standard or short implant placement. Data will be collected at regular follow-up visits up to 1-year post-surgery.

Inclusion Criteria:

• Patients with atrophied posterior mandible with less than or equal to 6 mm of bone over the inferior alveolar canal
• No previous grafting or implant surgery at the site where nerve lateralization is planned
• No neurosensory impairment
• No contra-indications for implant surgery

Exclusion Criteria:

• Patients who have undergone radiotherapy in the associated area
• Patients using bone-modifying agents
• Smokers with daily consumption of more than ten cigarettes
• Patients with neurosensory impairment due to trauma, tumor, or cancer
