简要总结
o evaluate the radiologic proximity of mandibular dental implants placed less than 2 mm from the inferior alveolar canal using cone-beam computed tomography (CBCT), and to determine the relationship between implant-canal distance and the occurrence of postoperative neurosensory disturbances.

入选标准
- •Age ≥ 21 years.
- •Implants placed in mandibular first/second premolar or molar positions (Froum et al., 2021).
- •Patients without neurosensory changes following implant placement and healing (Froum et al., 2021).
- •Patients with neurosensory changes after implant placement, including paresthesia, anesthesia, dysesthesia (and neuralgia where applicable) (Froum et al., 2021).
排除标准
- •Incomplete records preventing outcome ascertainment (Froum et al., 2021).
- •Refusal/unavailability of postoperative CBCT when clinically required for evaluation (Froum et al., 2021).
- •Poor-quality CBCT scans or scatter artifacts interfering with evaluation (Froum et al., 2021).
- •Contraindications for radiographs (e.g., pregnancy/breastfeeding) in cases where additional imaging would otherwise be clinically required (Froum et al., 2021).
- •Implants placed after mental foramen
