Dental implant study aims to prevent nerve damage
NCT ID NCT07363239
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study reviews past records of 100 people who had dental implants placed in the lower jaw. Researchers want to see if placing implants very close to a major nerve (the inferior alveolar nerve) causes numbness, pain, or other nerve problems. They will use 3D X-rays (CBCT) to measure the distance between the implant and the nerve. The goal is to find a safer distance to help dentists avoid nerve injury.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help dentists place implants more safely and reduce the risk of nerve damage.
- What could go wrong
- This is a small, retrospective study that only looks at past records, so it cannot prove cause and effect. Results may not apply to all patients.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Age ≥ 21 years. 2. Implants placed in mandibular first/second premolar or molar positions (Froum et al., 2021). 3. Patients without neurosensory changes following implant placement and healing (Froum et al., 2021). 4. Patients with neurosensory changes after implant placement, including paresthesia, anesthesia, dysesthesia (and neuralgia where applicable) (Froum et al., 2021). Exclusion Criteria: 1. Incomplete records preventing outcome ascertainment (Froum et al., 2021). 2. Refusal/unavailability of postoperative CBCT when clinically required for evaluation (Froum et al., 2021). 3. Poor-quality CBCT scans or scatter artifacts interfering with evaluation (Froum et al., 2021). 4. Contraindications for radiographs (e.g., pregnancy/breastfeeding) in cases where additional imaging would otherwise be clinically required (Froum et al., 2021). 5. Implants placed after mental foramen
