简要总结
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.

结局指标
主要结局
Light touch test results
时间窗: Visits at 10 days, 1 month, 2 months, 3 months, 6 months, and 1 year after surgery
The light touch test is a common diagnostic tool used to assess sensory perception. Patients' lower lip and chin areas will be gently stroked with a soft object, such as a piece of cotton or a brush. The patients will then be asked to report their sensation. If they feel the touch, the response is considered normal. However, any reported changes, such as numbness or tingling, can indicate possible nerve damage or recovery after surgery.
2-point discrimination test results
时间窗: isits at 10 days, 1 month, 2 months, 3 months, 6 months, and 1 year after surgery.
The 2-point discrimination test is a neurological examination used to measure tactile spatial acuity. Two points of a caliper will be applied to the patients' lower lip and chin areas. The distance at which a patient can no longer differentiate between the two points provides an indicator of sensory nerve function. Any reported changes in the ability to distinguish between two points may suggest alterations in nerve sensitivity or recovery after surgery.
次要结局

- Thickness of the mandibular inferior border(At baseline)
- Thickness of the buccal cortex(At baseline)
- Distance from the nerve canal to the buccal cortex(At baseline)
- Change in peri-implant bone resorption(At 3 months, and 12 months after surgery.)
- Distance from the nerve canal to the inferior border of the mandible(At baseline)
- Change in Implant stability quotient (ISQ) values:(During implant placement and follow-up visits at 3 months.)
- Patient satisfaction(At 12 month follow-up visit)
