Official title

A New Concept of Safety Distance to Place Implants in the Area of the Inferior Alveolar Canal to Avoid Neurosensory Disturbance: A Retrospective CBCT Study

Overview

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.

Interventions

  • Other nerve approximation group
    implants placed with distance more than 2 mm from the inferior alveolar canal

Primary outcome measures

  • Neurosensory outcome [Time frame: 6 months]

Eligibility criteria

Inclusion criteria

  • 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).

Exclusion criteria

  • 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

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
